I'm struggling to get the Radeon driver to work on my eMac G4's Radeon
7500 card (the fbdev driver works fine at 1024x768 with no
acceleration). On both Fedora 8 and Fedora 10 with default xorg.conf,
the screen is blank (the CRT doesn't glow or anything). I have a CRT
monitor that supports up to 1280x960. The eMac also has a video out
port. I suspect that video may show up on an external monitor, but I
can't test that until my adapter arrives.
With an unmodified configuration, Xorg accepts clients and the
/var/log/Xorg.0.log looks good. However, the screen is blank. I
suspect this may be bogus modelines. I tried a modeline I grabbed
from fbset in the working radeonfb Linux terminal:
$ fbset -x
Mode "1024x768"
# D: 99.197 MHz, H: 72.090 kHz, V: 89.001 Hz
DotClock 99.198
HTimings 1024 1072 1168 1376
VTimings 768 769 772 810
Flags "+HSync" "+VSync"
EndMode
I tried adding this mode through xrandr as follows:
$ xrandr --newmode "1024x768j" 99.198 1024 1072 1168 1376 768 769 772
810 +HSync +VSync
$ xrandr --addmode DVI-0 1024x768j
$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2048 x 1024
DVI-1 disconnected (normal left inverted right x axis y axis)
DVI-0 connected 1024x768+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm
1024x768 59.9*+
800x600 60.3
640x480 59.9
1024x768j 89.0
S-video disconnected (normal left inverted right x axis y axis)
$ xrandr --output DVI-0 --mode 1024x768j
xrandr: Configure crtc 0 failed
Just trying to xrandr to a different resolution fails:
$ xrandr -s 800x600
Failed to change the screen configuration!
And VT-switching to 7 (where Xorg is running) results in Xorg
segfaulting whether I do any of the above or not:

I tried adding my magic modeline via xorg.conf, but Xorg doesn't seem
to be taking it. Here is my xorg.conf:

This time, xrandr says:

(note that my modeline is missing)
My Xorg.0.log for this attempt is at
http://www.funsitelots.com/pub/Xorg.0.log_emacG4
How can I get Xorg to accept my modeline so I can see if this one will work?
