But not for me (sob). I put in my yaboot.conf
image=/vmlinux
label=debian-aty
root=/dev/hda10
read-only
partition=10
append="video=aty128fb:mode:1024x768-60"
with and without the "mode:1024x768-60" string. In both cases boot is
ok, but the screen turns blank. I have to login as root and reboot with
a "video=ofonly" image. Here are interesting kernel messages:
boot with video=ofonly:

I also couldn't get your first suggestion ("current" as mode and depth 8
in XF86Config) to work, the server always deleted all modelines. I tried
Section "Monitor"
Identifier "LCD Panel"
VendorName "Apple"
ModelName "Studio Display"
...
HorizSync 48.4
VertRefresh 60, 75
EndSection
...
Section "Screen"
Driver "FBDev"
Device "Linux Frame Buffer Device"
Monitor "LCD Panel"
DefaultColorDepth 8
SubSection "Display"
Depth 8
Modes "current"
#Virtual 1280 960
EndSubSection
EndSection
for the LCD flat panel we have (Apple Studio Display). Apple is thin on
specs in the manual where I find "1024 by 768 at 60 Hz refresh rate" and
two lower resolution modes at 75 Hz refesh which get mapped to 1024x768.
Oh, and fbset -x (when running with video=ofonly) tells me
mac108:/home/skluth# fbset -x
Mode "1024x768"
# D: 100.000 MHz, H: 93.985 kHz, V: 116.318 Hz
DotClock 100.001
HTimings 1024 1040 1048 1064
VTimings 768 784 792 808
Flags "-HSync" "-VSync"
EndMode
which has almost twice as much vertical refresh than Apple says? Should I
paste this into XF86Config? Or will I smoke-test the display?
Cheers, Stefan
