Re: Possible movement on VIA P4M800 graphics bug
I have a similar chipset that was misbehaving earlier. It seems to be different enough to be working with the latest update.
Code:
01:00.0 VGA compatible controller: VIA Technologies, Inc. CN896/VN896/P4M900 [Chrome 9 HC] (rev 01)
Previously I was using the vesa workaround. Removed everything vesa (I thought) and found that the monitor wasn't working AT ALL after login. The culprit was displays.xml in ~/.config/xfce4/xfconf/xfce-perchannel-xml, which had a refresh rate of 0, for some reason. Once that file was gone, all was OK.
BACKUPS are unsexy — until you discover you should have done one yesterday.
Spare your nerves and do one before you upgrade or install.
