Video

nouveau

• seems to have only a reduced palette
• dual-screen with DP/hdmi output works
• audio via HDMI fails
• 3D (e.g. compiz) fails
• flickering of screen at all resolutions after a while

nvidia

cf http://wiki.debian.org/NvidiaGraphicsDrivers

aptitude install nvidia-glx

Create /etc/X11/xorg.conf:

Section "Module"
   Load        "glx"
EndSection

Section "Device"
   Identifier  "Video Card"
   Driver              "nvidia"
EndSection

• smoother palette
• no additional output, xrandr sees only the LID :(
  • nvidia-settings has to be used instead of xrandr
• audio via hdmi fails but cf previous point, need first to get hdmi working at all...
• 3D works
• console font gets bold??
• flickering here too...

Touchpad

Was a hell to get something else than a stupid "ps/2 mouse"

A few bugreports are tracking the problem, e.g. on Fedora and Ubuntu, where I could find a very freshly patched psmouse driver

wget http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.9/psmouse-alps-dkms_0.9_all.deb
sudo modprobe -r psmouse
sudo dpkg -i psmouse-alps-dkms_0.9_all.deb 
sudo modprobe psmouse

And everything works like a charm, e.g.

synclient -l
synclient CircularScrolling=1
synclient VertTwoFingerScroll=1
synclient HorizTwoFingerScroll=1

Audio

Internal mic was working OOB but I cannot output sound on the HDMI.
Tried several snd_hda_intel options such as model=dell-s14 but no progress.
Some info...

• Card:HDA Intel Chip: IDT 92HD81B1C5
• Card:HDA NVidia Chip: Nvidia GPU 0b HDMI/DP

Apparently hdmi audio is not supported by nouveau, only by proprietary drivers, pfff

Suspend

Suspend to RAM sometimes freezes and I've to force power off.
