[Openchrome-users] Scrambeld screens in Ubuntu 7.10 with VN800

[Christiaan van Dijk]

Hi,

just ran into a comparable problem with my CN700. Decided to update all 
drivers to the latest version (DRI/Openchrome). All worked fine until I 
switched to VBE modes, want this for best support of the DVI extension 
board. With VBE modes got all  the problems as described below.
Now fixed the problem by downgrading DRI  to an older version. Need to 
play a bit more with DRI to find the latest correctly working version.

Regds,
Christiaan.
