Red Hat Bugzilla – Bug 213444
system-config-display does not change resolution in FC6
Last modified: 2008-08-02 19:40:35 EDT
Description of problem:
In FC6, system-config-display does not change display resolutions. Display
resolution persists at its initial 1280x1024 even though the generic CRT
monitor is capable of lower resolutions.
My FC6 is installed on an Intel DG965SS motherboard with an Intel Integrated
Graphics Controller and model i810 Integrated Graphics chipset. FC6 works well
in all respects except this display resolution issue.
When I select 1024 x 768, system-config-display changes /etc/X11/xorg.conf from:
Viewport 0 0
Viewport 0 0
Modes "1280x1024" "1280x960" "1280x800" "1152x864" "1152x768" "1024x768" "1024x7
68" "800x600" "800x600" "640x480" "640x480"
Version-Release number of selected component (if applicable):
How reproducible: Please see steps below.
Steps to Reproduce:
1. In FC6 Gnome, go to System > Administration > Display.
2. Change resolution from default 1280x1024 to another resolution, say
4. Resolution should change to new value. It does not.
Screen resolution does not change after reboot.
Screen resolution should change to 1024x768 after reboot.
I even tried installing Linux with a resolution=1024x768 install
parameter but the resolution stayed glued to 1280x1024.
Also tried option "UseEDID" "false" without success.
I too have this same problem. After upgrading to Fedora Core 6, I tried to
change the screen resolution using Ctrl-Alt-'+' and Ctrl-Alt-'-' to no avail.
This feature was available from Fedora Core 5 and below. Some of us don't have
the visual acuity we had in earlier years. I need this feature to read the fine
print on some webpages.
With a Viewsonic VX2035mx-1 (1680x1050) lcd display and an Nvidia Geforce2 400mx
display adapter, setup fails to detect the lcd resolution and sets it at 800x600
and 640x480. When "1680x1050" "1280x1024" "1024x768" are prepended to the
Modes line in the xorg.conf file, the display defaults to 1440x1050 but shows
1680x1050. To obtain 1680x1050, 1440x150 must be selected and then the display
adapter runs at 1680x1050. The screen is then scrambled when a password prompt
pops up after the screen saver shuts down the diaplay.
The VIA UniChrome Pro video adapter embedded in the VT8237 chipset and the evesa
driver would not permit a setting that kept the horizontal settings from 90khz
even with HorizSync 30.0 - 82.0 and VertRefresh 50.0 - 85.0 lines added to the
Thank you for fixing this bug! You are a true mensch! I finally can read the
punchlines of Zippy the Pinhead! Are we changing resolutions yet?
