Notes

General

For proper support for the 6720S you should use kernel 2.6.22 or greater. Ubuntu 7.10 is a good choice for this laptop.

Graphics

To install older Ubuntu, or from Alternative CD you must chose 1024×768@16bit option, or manually add vga=791 to the kernel line, then the instalation will go smooth, and sweet :). Of course install the xserver-xorg-video-intel driver, when you finish the installation.

In Hardy compiz works out of the box.

Ethernet

You must upgrade to the newest BIOS, because the F.07< bioses, were known to have trouble with ethernet drivers in Linux (and also in Windows XP). After that you don't have to add `noacpi` options on boot, as it is said in some forums.

Wireless

* The Intel 3945ABG wireless controller uses the iwlwifi or the older ipw3945 module. Most recent Linux distributions should support this controller properly.
* The Broadcom BCM94311MCG wlan mini-PCI (rev 02) does not have a properly working native linux driver, so you must use ndiswrapper in distros like Feisty, and Gutsy. In Hardy Beta if you want make it work, you must patch the linux kernel with a proper patch (see forums), or the other, TEMPORARY, way is to remove the b43 nad b43legacy module with `modprobe -r b43` (i don't know why, but blacklisting just don't work), so you must do this every time you start ubuntu hardy and want to use Wireless, without the patch of course), and then use ndiswrapper.

Hibernation and Suspend

It is better to disable them from the beginning, as they won't work well on almost all linux distros, and can be really troublesome.

Tested on

Ubuntu Feisty 7.04, Gutsy 7.10, Hardy Beta 8.04

Summary

As long as you use a recent stable Linux distribution (such as Ubuntu 7.10 or Fedora 10) you shouldn't have major problems with this laptop, because Wireless, and Graphics have an excellent community support.

Installed Linux Mint 16 Cinnamon 32 bit, works fine but don't overdo it :-)
At times huge CPU use.
Using 64 bit not advised, extremely High iowat% >90% and CPU > 93%

Try this page, it's what I used to fix graphic errors.

It's a BIG thread on Ubuntu's forums:

I have an issue with the SD slot working on Ubuntu 11.10. Everything else works pretty well except that. I just wanted to see if anyone here has any solutions.

Mahmt, 2011/11/30 23:47

Hi i installed ubuntu 11.4 in my hp compaq 6720s

RikBoland, 2013/12/14 21:40

Hi dude I had same issue so I plugged it to Ethernet, then download wireless driver. Updated software turned the computer off (this is the important part) made a cup of tea with a biscuit and dunked x3 then with out Ethernet cable turned back on the machine logged in and told it smelt my wifi

Arshad, 2011/11/24 07:20

I think I have finally reached the right place. Can you help with this:
I have upgraded to Ubuntu 11.10 on HP Compaq 6720s notebook. Everything was working fine with 11.04. The widescreen aspect and actual resolution info has somehow been lost either during upgrade or my tweaking.

Supported resolution of the Compaq 6720s is 1280×800.

Some info about the system:

$ sudo lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile GME965/GLE960 Integrated Graphics Controller (rev 0c)

$ sudo xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768
default connected 1024×768+0+0 0mm x 0mm
1024×768 61.0*
800×600 61.0

I tried to manually add the resolution (1280×800) but that didn't work. Here is the result:
$ sudo xrandr –newmode “1280x800_60.00” 83.50 1280 1352 1480 1680 800 803 809 831 -hsync +vsync

xrandr: Failed to get size of gamma for output default
xrandr: screen cannot be larger than 1024×768 (desired size 1280×800)

(Note: While max size reported by xrandr above is less than 1280×800,
ddcprobe detects everything correctly)

Help is required.

Hi

I hope that you can help!

When ever I turn my Compaq 6720s on instead of going to boot my os it goes strait to Memtest86 and wont allow me to do anything else.

What maybe the issue?

Igor, 2011/08/26 19:55

Hi

The mouse pointer isnt moving or the two fingered scroll isn't scrolling?

Pau, 2011/03/20 12:58

Hi, all my devices are intel,and I've installed ubuntu since 2 years ago, there is only a problem, i can't hear the speakers of laptop and i must use some external, someone could help me?

JaZm0n, 2011/03/13 01:12

I just installed Ubuntu 10.10 32-Bit Desktop Edition on my old HP-Compaq 6720S.
Install went great and the only thing I had a problem getting to work was the wireless connection.

I used the following command to find out my wireless chipset in Applications / Terminal
“lspci -vnn | grep 14e4” - In my case “broadcom BCM4312 802.11b/g”

I enabled Broadcom STA wireless driver (System / Administration / Hardware Drivers / activating “Broadcom STA wireless driver”). - Needed an ethernet connection for download.

With my wired connection plugged into my Netgear WNR2000 router, I opened a webpage and went to the router address “192.168.1.1”

There was a router firmware update available which I downloaded after which my wireless worked with Ubuntu :-)

Not 100% sure if just connecting to the router with the wired connection or the firmware update done the trick (most likely the FW update).

Hopefully this may help someone else who is having problems getting their 6720S wireless to work.

JaZm0n, 2011/03/13 01:16

Forgot to mention after I enabled the broadcom STA wireless driver I could see my wireless router but it would not connect.

Ross, 2010/11/02 14:53

Here is native drivers for Broadcom in 6720s

Ross, 2010/11/02 14:57

And here is how to compile the driver:

svakulenko.a, 2010/10/14 19:50

I have hp 6720s, in my opinion, this model not optimized for linux. Main disadvantage is integrated graphic card. I tried all hints, all kind of drivers, raw, old, new - result always the same, laptop work very slowly (tested on kubuntu, fedora, ubuntu). I hope that my next laptop will be more computable with linux.

pip, 2010/10/15 07:00

I guess that it just depends on what kind of a graphic controller you get. Mine is Intel Corporation Mobile GME965/GLE960 Integrated Graphics Controller, and it works quite well. Unfortunately, when buying such things, it has become almost impossible to know what sorts of hardware one'll get. My 6720s variant is KE109EA (all Intel parts)

/sbin/lspci says


00:02.1 Display controller: Intel Corporation Mobile GME965/GLE960 Integrated Graphics Controller (rev 0c)
00:19.0 Ethernet controller: Intel Corporation 82562GT 10/100 Network Connection (rev 03)
00:1a.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #4 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev f3)
10:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

Mepis 8 works very well, fast and smooth, good battery life…even keyboard shortcut for display brightness (other shortcuts don't work); suspend and hibernation not tested

Charles, 2010/10/05 14:20

I have been running Debian GNU/Linux lenny on the Compaq 6720s for the passed three years. It runs perfectly well and all the hardware works out of the box. The battery life is very low. How can I increase the battery life? Can someone assist?

Abdelrahman, 2009/11/15 21:38

my have problem with my hp 6720s is that the power manger doesn't contain the on battery tap so when i remove the ac power supply the brightness decrease and after a moment it dims so every minute to increase the brightness

Omar Herrawi, 2009/11/14 21:10

UBUNTU 9.10 works perfectly on my HP 6720s.

Including hibernation and suspend.

The only problem that it eats my battery,Windows XP can stay for 4 hours..with Ubuntu i am lucky if the battery lasts for 2 hours.

nitaku, 2009/05/04 15:14

Raheem,

Would you please write to me what have you done to make Slackware working on HP 6720s?

nitaku, 2009/05/04 15:11

The chart above is a lie as is.

I'm having the aforementioned laptop HP Compaq 6720s.

After installing Slackware I'm having problem with the screen resolution,
I tried 'xorgsetup' 'xorgconfig' still I'm having two black lines both sides of the display.

I would be glad if Slackware would eventually would work on my laptop.

Backtrack uses Slack and I have never had a problem with that,- so Slack should work too.


Thanks for anyone in advance who can help to solve this problem.

robson, 2008/10/16 05:39

openSuSE 11.0

ethernet works if acpi=off in kernel
wifi doesn't work without ndiswrapper
touchpad doesn't work when you turn on 3D acceleration

Bill Giannikos, 2008/10/22 03:25

acpi=off turns off all power management for your laptop and so isn't recommended.

murdercode, 2008/09/21 00:43

Test by me

Ubuntu Hard Heron : works great . but it crash on the x server … wireless ok
Sabayon 3.5 : excellent , it need to install wi-fi ;)

everything can be get working, 2008/06/19 04:27

Ubuntu Hardy 8.04

I've found all the infos I needed here http://ubuntuforums.org/showthread.php?p=5211201#post5211201

Raheem, 2008/05/09 08:14

Tested Distros

Fedora Core 8 - everything works out of the box. except the wireless .. requires ndiswrapper
Mandriva 2008 - everything works out of the box, except the wireless .. ndiswrapper required use the gui tool provided - very easy
Suse 10.3 - Works great .. needs ndiswrapper for wireless.
Slackware 12.0 - video needs tweaking. wireless needs ndiswrapper
Sabayon 3.4 - experimenting on it now

pip, 2008/12/21 01:46

Fedora 10 - HP 6720S variant KE109EA has all Intel chips (Ethernet, USB, Wireless, IDE, Display) and everything works out of the box. Anaconda installer didn't at first finish GRUB bootloader installation, but started again in System Repair mode all went OK.
