Red Hat Bugzilla – Bug 128113
Screen resolution changes everytime system boots
Last modified: 2014-06-18 05:07:28 EDT
Description of problem:
I did a fresh install of FC2 on my DELL Dimension 8100 desktop with
ATI RADEON 7200 graphics card and Sun 21" monitor (Sony GDM-20E20). In
the window manager I can set the resolution to 1600x1200@65Hz which
works great as long as I don't reboot the box.
When I reboot the box screen goes blank during "start-up" and the
"login screen". Since I setup to "auto login" I do get the window
manager to display but only in 1152x864. I will have to manually
change resolution back to 1600x1200 everytime.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install FC2
2. Set screen resolution to 1600x1200

Are you setting the resolution using Preferences->Screen Resolution?
That's using xrandr to set the resolution up.
Thanks for the conf/log file - investigating
Yes and I also used "display" settings too with the same results.
I think both utilities update /etc/X11/xorg.conf.
Thanks for all your help.
No preferences->screen resolution does not update the config it uses
xrandr to dynamically change resolution.
Just to confirm, the attached config file and logs are after setting
up resolution to 1600x1200 using system-config-display and booting?
Can you attach the output of xrandr -q
Is there an option in Preferences->Screen Resolution for 1600x1200
@75Hz as this is what X is trying to set and failing.
The attached log is from an X server configured to start up in
1600x1200 resolution, which is correctly starting up in 1600x1200.
If you're sometimes experiencing it not starting up in 1600x1200, then
we need an X server log file from when it starts up in a different
resolution. Whatever is causing it to not start in 1600x1200 will
be present in the log file. Comparing the two will show the problem
The current log file attached here says "1600x1200 works fine"
though. Can you attach log from failed startup?
I'm running into the same problem but on FC4. This is a new problem for me. (or
seems to be) I don't have to restart that often but about 2 weeks ago this
started happening and I've noticed on reach reboot that I have to reset my

This is my Xorg log when its not working
When I reboot my system it comes in at a resolution of 1600X1200 even though I
change it and set as my default 1280X1024. This is what my Xorg log looks like
before the switch

I'm including my xorg.conf in the hopes that this helps.

Remove "1600x1200" from the end of the list there. Does the problem go away
