Linux video installation is really tiresome.
Consider the old laptop I am installing at the moment with Via graphics.
Toying with the idea of Archbang Linux, I had to add modprobe.blacklist=viafb
to the kernel boot parameters to get it started. Once installed, it was too unstable. So ... switch to the best ... Sabayon 10 XFCE amd64.
During installation the graphics display was fine - correct resolution, no issues at all.
On boot up the graphics presented the Sabayon wallpaper, but zoomed in on the "X" of "Sabayon X". No menus, visible. Just a mouse cursor. Apart from cursor movement the system was frozen. Trying to switch to a terminal ALT-CTRL-2 gave a black screen. modprobe.blacklist=viafb did not help.
Rebooting into revovery, X -configure
failed with "Number of screens does not match number of detected devices"
startx took several seconds, but eventually two terminal prompts appeared in windows with white background.
xrandr shows an * next to 1920x1200.
Xorg config is here: http://bpaste.net/show/67032/
Any advice would be much appreciated. Does anyone know of a detaled Linux video troubleshooting guide?
