Bug#373219: xserver-xorg: Runs at inappropriate resolution, despite successful video and monitor detection



Package: xserver-xorg
Version: 1:7.0.20
Severity: normal

I generated this bug report a few days ago using reportbug, but it failed to
send automatically. So, I'm forwarding it now by hand, and I've attached
copies of my xorg.conf file and the results of "debconf-show xserver-xorg".
(The report is from the same day as the email. I've now updated to version
7.0.22, but the problem persists.)

Package: xserver-xorg
Version: 1:7.0.20
Severity: normal


When I run X, it runs at 640x480 and reports the refresh rate as 
somewhere around -17000 Hz. When I check /var/log/Xorg.0.log, it appears 
to have correctly detected my video card (ATI Radeon X800 XL) and my 
monitor (DELL 2405FPW) and confirmed that various resolutions up to 
1920x1200@60 are valid on the primary head.

I upgraded my monitor to the current one in early May and at first it worked
very nicely at 1920x1200. As far as I know, my packages were up to date at 
that time, as I update frequently. About a week later, in mid-May, I 
updated my packages without any apparent errors, but the next time I ran 
X this problem occured. In all other ways, X seems to run ok still. But, 
I consider it unusable at 640x480 (at least with my current settings for 
fonts/icons, etc.) so it is effectively completely broken for me.

I've tried auto-updating my xorg.conf file, in case that was the 
problem (even though the file I had worked fine for a week). 
Unfortunately, I'm having problems that seem to have been mentioned in 
previous bugs (e.g., #363965), and I can't get the file to regenerate. 
I've tried "dpkg-reconfigure xserver-xorg", and I've tried it with the 
-phigh flag, but in both cases it doesn't even touch the modification 
time. With the -phigh flag, it doesn't even ask all of the setup 
questions.

I don't know why debconf-show failed in the system info below. 
"debconf-show xserver-xorg" worked when I ran it by hand. It's difficult 
for me to paste the information into this message, since I'm running at 
console now, but I will be happy to try to provide any system/config 
information you would like to see if you let me know. I am eager to fix 
this problem and get my system back into a usable state.

By the way, I don't know if this is the source of the problem or 
irrelevant, BUT:
In the log file, the radeon driver "Failed to detect secondary monitor 
DDC", which is appropriate since I'm not using a secondary monitor. It 
then assigns default statistics to this non-existant monitor, rules out 
all resolutions as invalid (including 640x480), and assigns it a default 
resolution of 640x480. It is clearly aware that this is the secondary 
display, and my xorg.conf is set up for only one screen, but it seemed 
worth mentioning since the primary display isn't working correctly. 

Thank you for your work on these packages, and I hope this problem can 
be resolved without too much trouble.
