Description Sebastian Noack 2007-11-18 08:31:49 UTC 
When I boot my system and start X, everything is fine. But when I kill X and start it again xorg uses a resolution of just 800x600 instead of 1400x1050 as before. When i run xrandr, the only available resolutions listed are 640x800 and 800x600, after restarting X. When i reboot my system it is fine, again.

I pasted my xorg.conf at the bottom of this bug report, but this problem also occurs when I use the configuration generated by Xorg -configure without changes.

Comment 1 Sebastian Noack 2007-11-19 04:39:42 UTC 
I also tried two older versions of the linux kernel (2.6.18.8 and 2.6.23.1) and the new xorg-7.3 with xorg-server-1.4. But the problem still exists. I am currently using the "vesa" driver instead of the "radeon" and it works. But this doesn't solved this bug.
Comment 2 Alex Deucher 2007-11-19 06:36:16 UTC 
Please attach (as opposed to cutting and pasting) your xorg logs (working and non-working).

Comment 6 Alex Deucher 2007-11-20 09:14:05 UTC 
The second time around the driver is finding a second monitor attached for some reason and attempting to use it.  The following should fix it:
Option "MergedFB" "FALSE"
Comment 7 Sebastian Noack 2007-11-21 12:48:22 UTC 
Thanks. This worked for me. But even though I don't use MergedFB, shouldn't it work with the radeon driver?
Comment 8 Alex Deucher 2007-11-21 14:27:15 UTC

For some reason it's detecting a phantom monitor on the second start up which is causing your problem.  Turning off mergedfb causes the driver to ignore the second output.
Comment 9 Alex Deucher 2007-12-11 09:36:03 UTC 
The old version of the driver is no longer actively maintained.  Please upgrade to the latest version.
