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: -------------------- Section "Device" Identifier "Videocard0" Driver "i810" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection -------------------- to: -------------------- Section "Device" Identifier "Videocard0" Driver "i810" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1280x1024" "1280x960" "1280x800" "1152x864" "1152x768" "1024x768" "1024x7 68" "800x600" "800x600" "640x480" "640x480" EndSubSection EndSection -------------------- 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 1024x768. 3.Reboot. 4. Resolution should change to new value. It does not. Actual results: Screen resolution does not change after reboot. Expected results: Screen resolution should change to 1024x768 after reboot. Additional info: 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 Monitor section.
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?
