Red Hat Bugzilla – Bug 121855
can't set resoltuion to 1400x1050

system-config-display gives me the choice of resolutions 640x480 and
600x800, even though my system is capable of up to 1400x1050 - in
fact, it is at the moment runnign at 1400x1050, even though this
resoltuion does not show in system-config-display. I am attaching
The system is Dell Latitude laptop with 1400x1050 LCD screen and ATI
Radeon 9000 Mobility video card

I did a clean install FC2-T3, three times. The system here is a
Gateway M500 using a nVidia GeForce4 420 Go video card, which uses a
resolution of 1280x854. In FC1 & FC2-T2 I have been able to set the
1280x854 resolution by using a ModeLine but in FC2-T3 it fails to
work. The log shows the 'nv' module is being loaded, etc. but it also
says that all resolutions it tries to set the X server to are out of
range, including 1280x854. After it runs thrue all resolutions it
finally sets X to 640x480.
I was able to get the resolution in FC2-T3 "fixed" by installing
FC2-T2, setting up the system there and then doing an upgrade with the
FC2-T3 CDs. The X server settings were carried over to FC2-T3 and now
the resolution is correct.
Two observations - one, when I had the clean install of T3 running, it
used XF86Config. I don't remember seeing the xorg.conf script as
reported by Sasha. I was working with XF86Config. Two, with the
present configuration, T3 upgraded from T2, XF86Config is still being

From bug 123262:
I'm using a fresh FC2-t3 install. There are no legacy XFree86 configs.
Darin: Does /etc/X11/XF86Config exist? There was a bug in test3 that
was causing both XF86Config and xorg.conf to be written, which was
Though the question was not addressed to me, on my system XF86COnfig
Yes it did. Interesting, it was not there after the initial reinstall
I renamed it and rebooted but the problem still persists.
Isn't this a dupe of either 120950 or that kernel bug which was
recently fixed which caused DCC probes not to work? These have both
been fixed in rawhide/FC2, but will require you to rebuild your
xorg.conf with system-config-display.
That did it.
After reselecting "Generic LCD 1024x768" and "ATI Rage Mobility" the
first panel's resolution dropdown now offered 1024x768.
XFree86.config was not re-created.
