I have installed open suse 11.2 on my cq 40-108TU.I have two problems -

1.it can not detect wi fi.

2.I tried virtualization but it says “processors does not support virtualization”. I tried to see the bios options (as i saw it in a forum) but there was nothing regarding virtualisation.

I am using Linux Mint 8 on a Compaq CQ40-215WM.

It works perfectly. I couldn't imagine using Vista (which it was preinstalled with).


If you are a Windows sufferer trying to jump ship to Linux, use Mint. It will do what you want. No question about that.

ActionParsnip, 2011/02/01 18:26

Shame it's community is dwarfed by that of Ubuntu. Don't use a rehash of a great OS, use the original.

Manju, 2010/01/20 06:59

This solution by mark has worked for me it solved my problem i'm sure it will solve your sound problem too plz do reply after it solves yur problem

1. copy-paste the following command into the Terminal:

gksudo gedit /etc/modprobe.d/alsa-base.conf

2. and add these lines to the end of the /etc/modprobe.d/alsa-base.conf file:

# Keep snd-pcsp from beeing loaded as first soundcard
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=dell-m4-1
options snd-hda-intel enable_msi=1

3. Then navigate to System>Preferences>Sound and change everything to ALSA

4. copy-paste the following command into the Terminal:

gksudo gedit /etc/group

5. replace the following line (or something very similar to it):


with this line:


Stace, 2009/12/30 09:51


Thank you for this information. However, being an extremely new Ubuntu user, I don't know what you mean by:

* 3. Then navigate to System>Preferences>Sound and change everything to ALSA *

When I go to my Sound preferences, I see no ALSA options anywhere. Should this be in the Output tab, or Hardware? Is there something I need to download before this will work?



basha, 2010/03/18 11:14

thank u jyothi.

abhishek, 2010/06/07 18:11

Yes boys this worked me also. But earlier what was the prob.? Like to know what exactly we have done by following those steps? –any sources to give this info…?
