Notes

Graphics

There are two models of this laptop, one with a NVIDIA graphics chip and the other with an ATI chip.

NVIDIA Graphics

For the graphics to function fully you will need to install the proprietary NVIDIA driver. Have a look in the guides section of this site for installation instructions for a few Linux distributions.

ATI Graphics

Worked on first Ubuntu boot, with open source “radeon” driver, and then with “fglrx” driver in Ubuntu package manager.

See the guides section on this site for details on installing the fglrx driver on your Linux distribution.

Wireless

The Intel 5100 wireless works just fine as long as you are using a distribution with Linux kernel 2.6.27 or higher. Fedora 10 and Ubuntu 8.10 are good choices.

Sound

Sound is a problem with this laptop, unfortunately at the moment it does not work as standard.

First, try adding the following line to your /etc/modprobe.conf (or your distributions equivalent) file:

options snd_hda_intel model=hp-dv7

Then reboot the computer and see if sound works.

If sound continues not to work then you will need to install the latest ALSA drivers.

To install the latest ALSA just follow the steps from this thread: http://ubuntuforums.org/showthread.php?p=6589810#post6589810

Summary

Sound is the major issue with the HP Pavilion dv7t, there is some technical knowledge and work required to get it to work.

Logan Sackette:

purple_fedora here, and I am experiencing similar issues my laptop is labeled Pavilion dv7, and like I asked earlier the fingerprint reader seems to be non-functional but as far as I could find, it was because my laptop is one model newer than the driver that HP released. although I was able to obtain the .dll files and am trying to figure out where to go from there so anyone else out there feel free to chime in.

Upgrade alsa to the latest version by following the steps described here worked like a charm: http://ubuntuforums.org/showthread.php?p=6589810#post6589810

I just got a dv7t-3100 and I can't get the wireless to show up. I am running the latest SuSE 11 x64. Everything I read says it should be fine since the kernel is the latest and Intel says that it's built in. iwlan is installed. It just doesn't show up. The light on my keyboard says the hardware is running and it was working in windows 7 before I blew it away.

Any other ideas? Is it having problems with the 64 bit? I'm trying to use this laptop to get myself back into the linux world and this driver is driving me crazy.

Igor, 2009/10/04 02:46

I still cant figure out how to create the modprobe file and where, still looking around, whenever I find a solution it feels like im running into one more problem =)

Im really enjoying this distro but it has its problems and im determined to get it working.

Finally got everything working after installing the latest nvidia drivers and BIOS firmware.

Suspend did not work until I downloaded the latest firmware from the HP site, booted into windows and used the program from their website to reflash the BIOS.

I had also been getting weird lockups during grub-boot about once every 20-30 boots (just need to reboot and it worked fine after that). That also seems to have stopped since I flashed the BIOS.

Thank you!!! I've been searching for a solution to this issue for nearly a week, but nothing else has worked. I'm running MEPIS 8 RC1 64-bit on an HP dv7-1285dx entertainment laptop and this worked like a charm on it.

Again, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you… well, you get the idea, I'm sure.

could someone check and tell me what firewire chipset is used?

Anwer, 2008/12/15 19:53

With respect to getting sound working, you can create a '/etc/modprobe.d/sound' file with the following contents:

— cut here —
options snd-hda-intel model=hp-m4 enable_msi=1
options snd slots=snd-hda-intel
# u1Nb.Jqboh86TqAC:82801I (ICH9 Family) HD Audio Controller
alias snd-card-0 snd-hda-intel
— cut here —

It worked for me after a reboot.

Ubuntu 8.10 alpha-6 on dv7t

I have this laptop and I am running Ubuntu on it. 8.04 didn't work so well, the graphics was messed up and I would have to do too much to get the wifi working. I tried ndiswrapper, it installed correctly, even said there was a device, but it didn't work. Upon reboot, i saw that there were several errors about microcode something.

Anyway, installed 8.10 after reading that it has support for Intel 5100 wireless chipset and it sure did. Graphics is much better. I am still having some problems with sound. It seems to configured, because I hear some beeping when the computer starts, gnome actually. but then i can't play anything. In installed cheese and I didn't have to configured anything to get the camera to work.

I am still waiting for an easy way to configure the fingerreader. I have found some info, but that is too much way.
