I had problem to get my brightness work on my laptop. Press FN and F8/F9 work, but nothing happens even if I could increase/decrease. So I started to remove nvidia files from synaptic. Started to remove x11-driver-video-nvidia-current/dkms-nvidia-current that didn’t help (restarted). So I removed also x11-driver-video-nvidia173/dkms-nvidia173 (restarted) and nouveau driver didn’t help either. Then I removed x11-driver-video-nouveau and installed x11-driver-video-nvidia-current/dkms-nvidia-current but after x-server could not load. I thought writing startx would load x, no luck. I installed nouveau by: su (password) and then: apt-get install x11-driver-video-nouveau. Then by writing startx I could load x and I could get to my desktop. Problem now even if I install nvidia-current, nouveau driver is loaded and nvidia-settings are not in PCLinuxOS Menu → More application->Configuration.
cat /etc/X11/xorg.conf |grep Driver
So I want nvidia and not nouveau driver to load. Secondly how can I get brightness to work?
lspci | grep -i vga
