I just got this working with a CN700 (DRI works fine too). The driver or
Xorg or whatever doesn't detect the hsync and vsync values properly. You
have to add them to xorg.conf manually to work around this bug.
For example for my 1280x1024 LCD screen these are my Monitor and Screen
sections of xorg.conf:
Section "Monitor"
Identifier "Configured Monitor"
Option "DPMS"
HorizSync 30.0 - 80.0
VertRefresh 56.0 - 75.0
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
Obviously for your 1280x800 laptop screen you'd need to edit the
horizsync, the vertrefresh and display modes, but I'm sure once you
input the right values everything is going to work.
Back to 2001 everyone.
