แก้ไขจอกระพริบ

you can find how to make it work quite easyly over the forums, this post included.

For the video card :

1. Make sure the restricted driver is installed (in Synaptic search for nvidia-glx-new)
2. Execute this command in a terminal:
sudo dpkg-reconfigure -phigh xserver-xorg
3. Open Restricted Drivers Manager and enable the nVidia driver.
4. Reboot, and you should be good to go.



For the wifi :
mkdir /tmp/wifi
cd /tmp/wifi
wget http://snapshots.madwifi.org/special/madwifi-ng-r2756+ar5007.tar.gz
tar -xvzf madwifi-ng-r2756+ar5007.tar.gz
cd madwifi-ng-r2756+ar5007
make
sudo make install
For the soundcard :
Download/install "linux-backports-modules"
Add this line to /etc/modprobe.d/alsa-base : options snd-hda-intel model=acerI have a aspire 7220 and this technique worked well... Hope this'll work for you too.
