Hello sir,

These new notebooks are not well supported so we'll have to do some stuff in order to make the things work. Some things may not work at all, like the microphone.

I have a gateway notebook and I'd had the same problem when I installed any Linux distribution. Fortunately, Ubuntu was the only one to detect my wireless card without any problem. The problem I have is / was the Screen resolution, Audio + Microphone, FN Keys, other minor problems.

The ones I've fixed:

* The Screen resolution
* The Audio Output (Microphone doesn't work, tried something but ended up with a very very low microphone input)

To fix the screen:
Add to your /etc/X11/xorg.conf :

Section "Monitor"
Identifier "TVOutput"
Option "Disable" "True"
EndSection

(Same file, add after Section "Device"):
Option "monitor-TV" "TVOutput"

To fix the audio:
You need to install linux-backports-modules-2.6.22-14-generic and use this one when booting.

sudo apt-get install linux-backports-modules-2.6.22-14-generic

Use the command alsamixer and make sure the sound is not MUTED. UNMUTE IT.

---

That worked for me, hope it works your you. I hope the newer versions of Ubuntu (and other distributions / linux kernel) add support these notebooks / computers.

Make sure to back up your xorg.conf file first... Always a good idea.
To edit the file- copy this in a terminal.

sudo gedit /etc/X11/xorg.conf

Nothing is jumping out as a culprit here, since Daspah has had similar issues, you should follow his recommendations. All you need to do is edit your xorg.conf file. Painless as long as you follow directions.

sudo gedit /etc/X11/xorg.conf

just paste these in at the bottom of the file as Daspah recommended

Section "Monitor"
Identifier "TVOutput"
Option "Disable" "True"
EndSection

Read this one carefully, don't paste it all...(leave out the stuff in quotes)
(Same file, add after Section "Device"):
Option "monitor-TV" "TVOutput"

Then save and restart
Messing with the xorg.conf file is a linux rite of passage =) welcome aboard

If your audio is working, no need to install the backports kernel. You have the -generic, which is what I was hoping to see.

Post back with your results, please.

CORRECTION!

Read this one carefully, don't paste it all...(leave out the stuff in quotes)
(Same file, add after Section "Device"):
Option "monitor-TV" "TVOutput"

Should have said:
Read this one carefully, don't paste it all...(leave out the stuff in PARENTHESIS)
(Same file, add after Section "Device"):
Option "monitor-TV" "TVOutput"
