Kernel Issues

There was (technically still is} an issue around kernel version 3.2.1 where a tiny, insignificant piece of code was removed which was specific to this model of laptop. This causes a massive 'flickering' effect which, if you look closely, is the screen being moved horizontally about 10 times a second.

The only ways to fix this is to recompile your kernel, removing this line of code in the process

/* HP Compaq 2730p needs pipe A force quirk (LP: #291555) *
{ 0x2a42, 0x103c, 0x30eb, quirk_pipea_force }

or just upgrade your kernel to a version past 3.4-rc1

Ubtuntu 9.10 / 64bit

Everything works fine without post-installation tuning. Switching between laptop mode and base station mode works great with <Fn>+F4. I just add some tips for the scrolling in tablet mode (using the dedicated switch) :

To map the events with up and down keys, just add these two lines to your rotate script :
sudo /usr/bin/setkeycodes e007 108
sudo /usr/bin/setkeycodes e006 103

Note1: Invert the codes when you rotate your screen (see section “xorg.conf and Tablet Mode” below)
Note2: Add a line in /etc/sudoers to allow 'sudo /usr/bin/setkeycodes' without password

Ubtuntu 8.10 / 64bit

Installation took forever - would not boot from my external cd, so i had to convice it to use my sd card to boot and a separate partition on the hd for packages.

I had to use the “alternate” cd with the option acpi=off to get it to even boot - otherwise it crashes immediately.

Fortunately the network (lan + wlan) worked out of the box. WLan seems to randomly drop every once in a while, but will pick back up after a short time.

Starting X with the intel driver crashes the whole machine. Tried both the 2.4.1 (ubtuntu) and 2.4.2 (debian) version. Only luck was with the standard vesa drivers. Resolution is 1024×768.

The error seems to be in the kernel. Loading the it amd64 bit kernel from deb trunk main allowed ACPI to start, which in turn is required for all other hardware. Afterwards most things started to work just fine.

Tablet (pen), and Sound require tinkering (see below).

xournal has a bug in ubuntu 8.10:
working well in lucid 10.04

Debian Squeeze / 64bit

Most of the system works out of the box. The Tablet, extra keys and WWAN works by following the instructions below.

Wacom Tablet

The Wacom tablet needs a configuration file 65-xorg-wacom.rules in /etc/udev/rules.d with the following content:

ACTION=="add|change", SUBSYSTEM=="pnp", ATTR{id}=="WACf*", ENV{NAME}="Serial Wacom Tablet"
ACTION=="add|change", SUBSYSTEM=="pnp", ATTR{id}=="FUJ*", ENV{NAME}="Serial Wacom Tablet"
ACTION=="add|change", SUBSYSTEMS=="pnp", ATTRS{id}=="WACf*", ENV{ID_INPUT}="1", ENV{ID_INPUT_TABLET}="1", ENV{x11_driver}="wacom"
ACTION=="add|change", SUBSYSTEMS=="pnp", ATTRS{id}=="FUJ*", ENV{ID_INPUT}="1", ENV{ID_INPUT_TABLET}="1", ENV{x11_driver}="wacom"

Extra keys

Screen rotation, Extra keys etc, see below


Gobi WWAN, see below

Individual Errors


There seems to be an error in the DSDT, see This causes the battery and some switches not to work.

According to bug report this is fixed in kernel version 2.6.29-rc1 and above before that use the option mentioned below.

ACPI works fine when the option “fan always on on AC Power” is turned off in the BIOS.

STR (suspend to ram) working well in lucid 10.04 and fc14 (not in maverick 10.10)

Intel Video Driver

The drivers crashes when entering sleep mode. A related bug report is here:

According to the info from the GM45 chipset is only properly supported starting from version 2.4.2, but the package in Debian unstable (2.3.2-2+lenny5) contains all the patches necessary. On the other hand, the kernel has to be patched to have AGP working properly. The patch can be downloaded from here:

It's already incorporated into 2.6.28-rc2.

One thing to notice is that 3D acceleration is much faster in landscape mode (1305 FPS in glxgears) than in the portrait one (112 FPS only).

screen rotation works fine with intel 2.5.0~git20081023 / kernel 2.6.27, but crashes with intel 2.5.0~git20081023 / kernel 2.6.28-rc3

Some combinations leave traces on the screen, best results where achieved with video-intel 2.4.1-1ubuntu10 / kernerl 2.6.28-rc3

on lucid lynx 10.04 LTS

second Monitor recognized and working from vga-port (maverick 10.10 does NOT! out of the box, like fc14 and sabayon 5.4)

Screen Brightness

Adjustment of the screen brightness. Using Gnome Brightness Applet doesn't make any changes and neither does cating various values into


I've managed to adjust brightness using these commands:

xrandr --output LVDS --set BACKLIGHT_CONTROL native
xrandr --output LVDS --set BACKLIGHT 9000

but the second one takes way too long to have it assigned to the dedicated buttons.

The largest possible value seems to be 12382

  • on lucid 10.04 brightness adjustment works fine out of the box via fn-f9 fn-f10 and fn-f11.


In current distros based on xorg server 1.5 (ubuntu 8.10 or fedora 10 preview x64), you should set the following setting in the “intel” section of your xorg.conf:

Option “Legacy3D” “true”

this decativates the GEM functions of the 4500hd, but resolves some problems:

* screen brightness changeable through gnome-powersettings / applet (keys don't work out of the box, but they are just not assigned)

* suspend to ram works out of the box

* xorg runs stable. (no crash at logout/shutdown)

Rotate-Button, HP Info button, Lid Rotation Switch

You need to load the module hp-wmi. Depending on your kernel version, the rotate button might not work (prior to 2.34).

To load the module at boot time, execute the following command as superuser

echo "hp-wmi" >> /etc/modules

Now we need sensible mappings for the scancodes. Add this to your rc.local above the “exit 0” line. Change the keycodes at will.

#up and down keys
setkeycodes e007 108
setkeycodes e006 103

#presentation button and info button
setkeycodes e008 229
setkeycodes 0x213b 178

You might want to recompile the hp-wmi module if your rotate button does not work. Add the middle line to
the driver/platform/x86/hp-wmi.c

{KE_KEY, 0x213b, KEY_INFO},
{KE_KEY, 0x231b, KEY_HELP},

The direction key is mapped to keycode 153 by default.

The rotation switch does not give an ACPI event, however there is a file /sys/devices/platform/hp-wmi/tablet that
indicates the current swivel status.

See for a script for automatic rotation. Use this script as basis to modify your working rotation script. Change the occurances of “dock” in ”…/hp-wmi/dock“ to “tablet”) and the 4 in the elif line to 1.

if [[ -e /sys/devices/platform/hp-wmi/tablet ]]; then
new=`cat /sys/devices/platform/hp-wmi/tablet`
elif [[ $new == "1" ]]; then

on lucid 10.04 first part of the script woks well and turns into portrait-mode, but second part after swiveling back to landscape does not


As the laptop has a built-in audio jack sensor, you will only have sound when you plug in your headphones with the out of the box setup. However if you use the following config it should work as expected.

cat /etc/modprobe.d/sound
alias snd-card-0 snd-hda-intel
options snd-hda-intel model=laptop enable=1 index=0

It may require 2.6.27 or later due to driver fixes.


Is more sensitive vertical than horizontal

Otherwise works fine, including the scroll zone.

The TouchStyk
you can set the middle mous button scroll (like on thinkpads) on Gnome with
sudo apt get install gpointing-device-settings
then find 'Pointing Devices' in the settings menu and look for 'emulate mouse wheel' and play with the key or button number (3?) in 'PS/2 Generic Mouse' as which the Styk is recognized. The price is to loose the paste-function for the middle click.
Didn't find a way to make the styk work as a 'left mouse click' on hitting the styk.

Fingerprint reader

It's an AuthenTec model, USB ID #08ff:2810.
It is apparently not going to be supported for a while, according to this:


You may have to download the current firmware from

Wireless confirmed to work solid unter 32bit without WPA.

Unter 64bit with WPA and 2.6.27 kernel there are sometimes drops - these may also be related to Ubuntus network manager - further investigation is needed.

Debian 64bit with WPA2, 2.6.28 kernel and wicd network manager wireless works without any problems.

Gobi WWAN Configuration

To get the 3G WWAN module to work you need:
* gobi_loader
* qcserial driver
* firmware for your WWAN-module
* (if kernel > 2.6.32) The following patches

In Debian Squeeze

apt-get install gobi-loader

As of latest 2.6.32-5 the wwan-patches is in debian kernel package!

== Compile and install a wwan-patched kernel ==
(hopefully this step is soon obsolete

* download kernel source, kernel patches and kernel-package
apt-get install kernel-package linux-patch-debian-2.6.32 linux-source-2.6.32
* unzip, apply debian patches as well as wwan patches to source
tar xfj /usr/src/linux-source-2.6.32.tar.bz2
cd linux-source-2.6.32
/usr/src/kernel-patches/all/2.6.32/apply/debian <patchlevel> (while writing it was 5)
patch -p1 < ../usb-wwan-2.6.32.diff
* make kernel package
fakeroot make-kpkg –initrd –append-to-version=+usb-wwan-patches kernel_image
* install kernel package

Install your firmware in /lib/firmware/gobi/

on lucid lynx 10.04 LTS

  1. needed to install gobi_loader (which is not yet in the repositories) from here via 'make' and 'sudo make install'
  2. needed also the firmware (amss.mbn + apps.mbn) from my vista-install (C:\QUALCOMM\QDLService\Packages\0\*, for my APN copied to /lib/firmware/gobi/* according to this (OK, in german but its not so hard to imagine, what Bob means …)
  3. then I made a 'sudo apt-get install linux-backports-modules-wwan' (my actual kernel is: 2.6.32-25-generic) according to (there's a problem with the usbserial-module in lucid)
  4. then un2400-WWAN worked via network-manager (well, I disabled the PIN of my SIM-card), even after awaking from Suspend To RAM (STR).
  5. what I like is the functionality of rfkill (sudo apt-get install rfkill)

on Maverick Meercat 10.10

  1. gobi_loader: It's now in the repositories: sudo apt-get install gobi_loader
  1. firmware: Copy it from you Windows installation. Copy both files from C:\QUALCOMM\QDLService\Packages\0 to /lib/firmware/gobi (or /etc/firmware/gobi, I copied it to both and don't know which one is right). If you're not in Germany, you may need to copy the files from another folder than “0”! I don't know how you find out, I'm in Germany and followed a german blog (see above).
  1. Now is a good time to reboot. Gobi should load the firmware driver at boot time.
  1. Install rfkill: 'sudo apt-get install rfkill'. If you 'rfkill list', you should see your wwan device. Note that lsusb may not show it! Rfkill reveals that wwan is “soft blocked”. Do 'rfkill unblock wwan' to unblock it. Now lsusb shows the device!
  1. Network Connection Manager should now offer an option to connect via wwan. May take a few (like, 5) seconds till it shows up.


Virtual must be at least 1280×1280 for rotation to work.

In this case it is: 1920×1280 (external screen) + 1280×1280 (internal), arranged horizontally.

xrandr --verbose | grep "LVDS" | grep ") normal ("

xsetwacom set "cursor" Rotate CW
xsetwacom set "eraser" Rotate CW

On Lucid 10.04: for 'xsetwacon set' you can take the device names in ”“ from 'xinput list' for stylus and erazor.


The right kernel with the right options is required. Installation requires a lot of patience for fine tuning.

Screen is blinking about every 2 seconds in grapic mode. I don't know how to fix it. Tried 2 distros: centos 6 and fedora 16. Ubuntu 11.10 doesn't boot from SD.

Windows works well.

anatheism, 2012/03/14 00:39

I fixed the flashing screen on CentOS 6 by adding acpi=off to the grub kernel argument.

Modiying the line in /boot/grub/grub.conf will make the change permanent so you don't have to add it at every reboot.

Saxony, 2012/03/15 17:26

Yes, flickering stops indeed, but you loose resolution (only 1024×768 instead of 1290×800) and some hardware needs acpi to ge detected … I'd been running Sidux → aptosid for about 3 years without that problem. It had been introduced with the 3.1-series kernels (3.2 same problem); running 3.0-7 had no issues. Unfortuneadly it isn't in the repos anymore (I decided to make a new installation some weeks ago without saving the kernel-deb before wiping the partition …).

Saxony, 2012/05/25 16:35

good news : install kernel 3.4.0 to get rid of the problem !

Xournal is in the Debian and Ubuntu repositories, the downside is it does not save the annotations in PDF as such, but exports is possible. An alternative might be Jarnal, but needs java.

Hello evryOne

Did someone try to use compiz with this Elite 2370p? : compiz frequently crashs the laptop, freezing the screen and forcing a hard reset.

Michael Hosack, 2011/08/31 05:07

Hi guyrodge,

I don't normally use compiz, but when I boot Knoppix 6.7.0 off a thumb drive it uses compiz by default. I didn't test it very much but it seemed to be working. I disabled a bunch of the compiz effects because I don't care for eye candy sucking up cpu cycles and power.

To boot off a thumb drive, I had to press <esc> while booting, then <f9> and then chose the option to boot off a usb drive.

If you try Knoppix 6.7.0, type “knoppix” at the Knoppix boot prompt, otherwise you will get the set-up for the visually impaired (talking menus, etc).

Knoppix often uses more up-to-date versions of software than is normally bundled with distros. If Knoppix works without the hiccups you encountered, then you may wish to use the same version of compiz. The website contains a list of the bundled software under the “Knoppix 6.7 Release notes”. It says compiz is version 0.8.4-4 .


Michael Hosack, 2011/02/07 04:02

“Squeeze” was just updated as the latest stable release of Debian (6.0.0). I installed the amd64 version on this device with an LXDE desktop and got most of the hardware working with help from this page. I found it necessary to use “xinput list” (as described by Teppo) in order to get the device names for the pen. I couldn't get the rotate button to work with the default 2.6.32 kernel and don't care to try a newer “experimental” kernel or recompile hp-wmi since it is easy enough to put a rotate script on the Desktop to click on. WiFi was not recognized until I installed the firmware-iwlwifi package from the “non-free” repository. After installing “alsamixergui”, audio worked without any configuration (haven't tested mic input). I haven't found a need for an xorg.conf with this installation so far.

For some reason /dev/sdb1 was pointing to a CDROM (non-existent for me since I don't have the docking station) in /etc/fstab . This made usb thumbdrives refuse to mount. Deleting this line fixed the problem but I don't know if that will cause problems with an external CD/DVD drive. I installed off of a usb — Debian has *greatly* simplified this process with Squeeze by providing “hybrid” CD images ( I initially tried to install the earlier stable release, Lenny, but that was a big headache.

Matthias, 2011/01/15 18:18

I'd like to give a little update on how I managed to install 10.10:

First of all, download the alternate cd and create a usb startup medium. This will also allow to encrypt your ubuntu partition before installation.

Your screen may not show anything until you did a full update after you installed the whole thing; All the acpi=off and so on thingies didn't work for me, screen stayed black. The trick is to connect a secondary monitor to your laptop, then the notebook screen will work (but, ironically, you won't see anything on the secondary screen).

Boot time is amazing compared to vista business!

Thanks to all who worked on this site :-)

eko, 2010/05/03 11:43

To get Rotate-Button, HP Info button and Lid Rotation Switch working you have to load the kernel module hp-wmi. Furthermore you have to map the keys with setkeycodes. Press one key once, than refer to dmesg to get the keycode.

cms, 2010/07/12 17:32

I loaded the module but dmesg doesn't give me any usable output. What scancodes did you use?

Watch Firefly, 2010/04/21 21:35

I was trying to boot my virus infected HP 2730p using Ubuntu 8.10 Live CD. It does not go beyond Ubuntu loading bar. I had similar problem with Dell Vostro 400, but after updating the Vostro's BIOS, it works like a charm. In fact, I cleaned Vostro by using Live CD.

I did not see any specific comments on BIOS requirements here. Will updating BIOS of HP 2730p to latest version will solve the problem?

Please advise.


Watch Firefly, 2010/04/24 18:24

Hi Everyone,

I just wanted to post an update. After installing new BIOS software F.0D-12/08/2009, I tried booting Ubuntu 9.10 Netbook Remix from the CD. It worked flawlessly.

Hope this helps.

This script rotates the screen either with the given parameter (0, 90, 180 or 270 degress), or, if no parameter is given, it iteratively rotates the screen for 90° in the clockwise direction.

It's a bit long, but not so complicated:


# Parameter (degrees rotation): [ 0 | 90 | 180 | 270 ]
# If no rotation is provided, the screen is rotated for 90° in the clockwise
# direction.

# Also, don't forget to create keyboard shortcuts (I used Alt+Right, Alt+Up,
# Alt+Left and Alt+Down).

DIGITISER_PEN="Wacom Serial Tablet PC Pen Tablet/Digitizer"
DIGITISER_ERASER="Wacom Serial Tablet PC Pen Tablet/Digitizer eraser"

function getNextRotation() {
    CURRENT_ROTATION=`xsetwacom --get "$DIGITISER_PEN" Rotate`
    case "$CURRENT_ROTATION" in
        "NONE" )
        "CCW" )
        "HALF" )
        "CW" )

case "$1" in
    "0" )
    "90" )
    "180" )
    "270" )

if [ -z "$RANDR_ROTATION" ]; then

xrandr --output "$SCREEN" --rotate "$RANDR_ROTATION"
xsetwacom --set "$DIGITISER_PEN" Rotate "$WACOM_ROTATION"
xsetwacom --set "$DIGITISER_ERASER" Rotate "$WACOM_ROTATION"

Also, sometimes after waking up from suspend the X and Y scaling is just erroneous. Appending these two lines at the end of the above script helps setting it back to default:

xsetwacom –set “$DIGITISER_PEN” xyDefault 1
xsetwacom –set “$DIGITISER_ERASER” xyDefault 1

Btw, I am using Fedora 12…

I have Ubuntu 9.10 running on this device. Most things work very well. Rotation is great with teppo's script above.

The only issue I have is that occasionally when I rotate the LED above the F5 key goes on. When that happens, the keyboard, track pad, and eraser head pointer are all disabled. Any ideas? It always seems to be when the screen is rotated to portrait and I've turned the monitor around.

I've not had an opportunity where I can do any real troubleshooting. I just use the stylus to reboot the machine then all works well. I have had times where if I leave the machine for a while then return to it things will have reset to normal again.

This is one of those odd quirks that only shows up once in a while, so it is difficult to troubleshoot.

Maybe you can tell about battery life time? I see your post is recent.

Chris, 2010/12/03 00:15

I have Ubuntu 10.10 running on another Elitebook (8440p). I get less than two hours of runtime, even with the battery settings configured to slow things down when unplugged. I get almost 4 hours when used with Windows 7.

Madmann, 2010/03/09 09:25

I have Ubuntu 9.10 running and have experienced the same thing: dead Keybord, trackpad and so on, on my machine i get these things to work again by switching the Wlan on and off or off and on again, maybee this will help you too.

I dont know where that results from, nor why switching the Wlan helps, but i dont mind aslong as it works this way

Ghabit, 2010/01/15 10:31

Can someone tell how long it works with battery? Tnank you.

teppo, 2010/03/01 21:37


screen 70%

with WLAN: 11-13W 1 battery: 3.5-4h 2 batteries: 7.5h-8h
without WLAN: 9-10W 1 battery: 4.5-5h 2 batteries 9-9.5h

My experience is about 7 hours when doing some heavy surfing and office use with the secondary slate battery attached.

teppo, 2010/03/01 21:41

ups !

with WLAN: 11-13W 1 battery: 3.5-4h 2 batteries: 7.5h-8h
without WLAN: 9-10W 1 battery: 4-4.5h 2 batteries 9h

teppo, 2009/11/16 21:36

The new X-server configures tablet with hal or something like that so xsetwacom doesn't recognize stylus etc. It can be fixed by changing the rotation script.

You can find out the new names by installing xinput and running “xinput list”.
Probably something like “Wacom … ”

My rotation script:

xrandr –verbose | grep “LVDS” | grep ”) normal (”
echo $test
if "$test" != 0; then
xrandr -o normal
xsetwacom set “Wacom Serial Tablet PC Pen Tablet/Digitizer” Rotate none
xsetwacom set “Wacom Serial Tablet PC Pen Tablet/Digitizer eraser” Rotate none

xrandr -o right
xsetwacom set “Wacom Serial Tablet PC Pen Tablet/Digitizer” Rotate cw
xsetwacom set “Wacom Serial Tablet PC Pen Tablet/Digitizer eraser” Rotate cw

hopefully this helps someone.

Does anybody got the Touchstick working as Touchstick with e.g. press2select?

teppo, 2009/05/05 03:12

Hey. Does anyone have one idea how to disable 2730ps internal speakers when docks sound output is connected?

shurik, 2009/03/20 21:46

Hello all,

I've just managed to connect to the Internet using un2400 on my HP EliteBook
2730p. Here are the steps.

1) Boot into Windows, start HP Connection Manager and load the firmware that corresponds to your wireless provider (I have AT&T). You might want to read if you have troubles with this step.

2) Boot back into Linux. Now the card should be visible for lsusb with _different_ product ID:
Bus 002 Device 003: ID 03f0:1f1d Hewlett-Packard
I suspect that this product ID can vary for different wireless providers.

Please note that you must NOT load the hp-wmi module as suggested somewhere. It apparently resets everything back (including the product ID that becomes 0x201d) and one has to repeat step 1 again. In fact, the Connection Manager even lists the card as “disabled” for a while.

3) Download this patch:

Apply the patch to your kernel source (it works fine with 2.6.28) and add one more line to drivers/usb/serial/qcserial.c after, say, line 26:
{USB_DEVICE(0x03f0, 0x1f1d)}, /* HP un2400 Gobi Modem Device */
Change the product ID approprietly if you have a different one. 0x201d will definitely _not_ work.

4) Recompile the kernel with qcserial as a module and reboot.

5) Load qcserial with “modprobe qcserial”. You should see some encouraging messages in /var/log/messages such as:

      Mar 20 15:58:54: USB Serial support registered for Qualcomm USB modem
      Mar 20 15:58:54: qcserial 2-2:1.2: Qualcomm USB modem converter detected
      Mar 20 15:58:54: usb 2-2: Qualcomm USB modem converter now attached to ttyUSB0

You can later have this done automatically by editing /usr/share/hal/fdi/information/10freedesktop/10-modem.fdi

6) Do “cat < /dev/ttyUSB0 & echo ATI > /dev/ttyUSB0”
You should be able to see some useful information about your modem.

7) Enjoy!!

By the way, the driver for Gobi apparently originates from Qualcomm itself
(read the comments at the beginning of qcserial.c). Hooray!!

shurik, 2009/03/20 23:45

Update: the card settings (firmware?) apparently don't survive suspend and shutdown of the laptop: the product ID is reverted to 0x201d and the card is
not recognized as a modem anymore. So one has to boot to Windows again in
order to reset it back to 0x1f1d. Anyone knows how to fix this?

teppo, 2009/03/03 00:35

I edited the rotation script to turn the screen to the right (and xsetwacom to CounterWise) because I think the laptop is designed that way.

If somebody disagrees feel free to leave a comment or just edit the wiki.

TheAshMan, 2009/01/30 16:28

Fedora 10 install worked with i686 DVD version, but on first reboot to finish setup and create first user it hangs on splash screen and never recovers. I edited the kernel boot command (thanks to Matej above) adding “acpi=off noacpi” –both for good measure– and it booted right up!

teppo, 2009/02/03 00:15

Problem you had is mentioned in ACPI section and is fixed in kernel 2.6.29-rc1 and above

Matej, 2009/01/03 00:11

Ok, I haven't read carefully enough. The 'fan always on on AC Power' option did the trick.

Sorry for the confusion. :) Bye!

Matej, 2009/01/03 00:02

Flashing BIOS in Vista (using the HPQFlash (68POU) tool from HP) did not help… I still have to specify the 'acpi=off' kernel boot argument in GRUB.

Oh, I forgot to metion that Fedora 10 pauses for several seconds on two occasions:

First when loading GDM and second when logging into the Gnome desktop (just before the Gnome Panel appears, both pauses show no disk activity for ~10 seconds (the same was not noticed on an HP nc8430 notebook and a G33 desktop -- both using the same version of Fedora 10).

Hope this info helped anyone… Bye

Matej, 2009/01/02 23:38

I've managed to install Fedora 10 i386 on my 2730p – but only with acpi disabled (which is very bad - no powertop for me :( ).

I had to use a bootable USB stick for installation. Sadly, there were tons of problems…

First, the specs of my tablet: [CPU=Intel Core 2 Duo SL9400@1.86GHz],[RAM=2GB],[Graphics=GMA 4500MHD].

Here is what I have done:
1.) I wanted to create an MBR backup (for the preinstalled Vista - just in case). However, I found no working Live CD Distro that would boot successfully… That is until I discovered (using the Ubuntu 8.10 live CD and the unetbootin bootable USB creation tool) that I had to specify 'acpi=off' in the kernel boot arguments. Ubuntu booted and I could use 'dd if=/dev/sda of=/mnt/Backup/VistaMBR.backup bs=512 count=1'. :)

2.) In order to install Fedora 10 I had to use the full i386 installation DVD and the 'liveusb-creator 3.2' tool FOR WINDOWS - only this version would let me put the DVD image onto my USB stick.

2.1.) The installation USB booted but would not install directly from the USB -- I had to use the 'URL' installation (obviously using wired internet connection). With this, the installation was concluded.
2.2.)  Vista was available in the Grub menu and booted without problems. The installed Fedora 10 would boot only if 'acpi=off' kernel boot argument is specified in Grub <-- this happened even after an update to the most recent kernel version (using the standard repository, of course).

Now I'm trying to update BIOS… God knows, perhaps it will help…

teppo, 2008/12/09 22:58

Just installed Debian testing on this computer. External monitor worked but setting the resolution to correct is kinda messy. Sound output and input aren't working.. No idea what to do with them.

Knetworkmanager can't find network interfaces although they work well pretty well with newest kernel from (maybe just some software missing.. don't know).

Everything else works just the way that is already stated before.

teppo, 2008/12/09 22:59

I meant to say that sound output/input in base aren't working.

teppo, 2008/12/09 23:57

Me again.. I found out that you need 0.7 version of network-manager to it to detect wlan interface.

antonio, 2008/12/04 01:40

Thanks to this page it took me only half a day to have my tablet working
with UBUNTU intrepid amd64: system,networking,X, sound,camera,stylus and digitizer.
I still have problems with WWAN,screen rotation,that sometimes closes my session,
sound in some applications,dhclient after wpa_supplicant, hibernation. Scroll button works but not the other tablet buttons.

SteveL, 2008/11/22 12:50

Ubuntu 8.10 on the elitebook with ATI

I've got most of Ubuntu 8.10 up and running on this toy. I had the version with the ati graphics card -with the proprietary driver it works well, except the picture on external monitors is pretty bad. More research is needed there -it could just be screwing up scaling.

Sound is down, even with the patches you've recommended; again more research.

Brightness from the gnome app works, and from software; its only the keys that are dead. That leaves wifi as the troublespot -I am exploring wcid to see if that is any better; I like its multiple WLAN profiles anyway.

Battery life is OK. Better than vista, though I'm still surprised by how hot it is and how much power it burns compared to my older laptop. The new, multiple cores may be efficient, but you pair for the pair of them in electrons. For deleting email and powerpoint, that's overkill, unless you run Vista, in which case your battery is toast. With Linux I have a real little workstation, though I miss the 1400×1050 resolution of its predecessor: the screen is wide, but short.
