[Intel-gfx] More on the i835GM problems on Fujitsu/Siemens

[Thomas Richter]

Hi Daniel, hi folks,

a bit more details on the intel-drm problem on the ancient 835GM based 
laptop. It seems that the problem of a blank
screen can be avoided by modifying the xorg.conf a bit. Currently, my 
xorg.conf contains a screen section as follows:

Section "Screen"
         Identifier "Screen0"
         Device     "Card0"
         Monitor    "Monitor0"
         DefaultDepth 24
         SubSection "Display"
                    Depth 24
                    Modes "1024x768" "800x600" "640x480"
         EndSubSection
EndSection


If this is replaced by

Section "Screen"
         Identifier "Screen0"
         Device     "Card0"
         Monitor    "Monitor0"
EndSection


then I do get a picture again when logging in. So it looks as if 
something is messed up when detecting the supported
modes for the chipset. Maybe this helps in hunting down the problem.

Sorry that I cannot bisect the problem further, I won't have this 
machine available for the next two weeks.

Greetings,
     Thomas
