Hi, I'm not really sure if this is the right place, as I suspect my issues are on the kernel-level, but I figure this would be a good start.
I'm playing with a Sylvania netbook based on VIA C7-M CPU with a VX700-based display adapter (see lspci and such below). It originally had a system called gOS which I didn't really like. I installed Debian Testing on it. It is currently running an up-to-date system with the latest kernel from Debian Unstable. Though I also had similar issues with various other Debian kernels (2.6.32-5-686 from Stable, 2.6.32, 3.0) and with self-compiled 3.0.8 and 3.2.0-rc2. When viafb is loaded the screen blacks-out immediately. If I disable loading it, I manage to get a display working. OpenChrome seems to be used in X. Not good enough for Gnome3, but it works. However if I try to suspend and resume, the system resumes OK, but the display is messed up. pm-suspend --quirk-s3-bios seems to work around it. Occasionally the system just hangs completely. I have no idea what makes it hang. I ran it with memtest86+ for a number of days and no problem was found. I see no aparant error message on the console. I tried running a network console a few times and got no useful output. I'm really at loss on how to debug/fix this. $ uname -a Linux vanmojo 3.1.0-1-686-pae #1 SMP Mon Nov 14 08:24:20 UTC 2011 i686 GNU/Linux $ lspci -nn 00:00.0 Host bridge [0600]: VIA Technologies, Inc.
