Red Hat Bugzilla – Bug 490385
Add wide screen modes to xorg-server by updating "extramodes"
Last modified: 2009-12-18 04:01:51 EST
Description of problem: 1920x1200 screen mode is not supported by the standard list of modes Version-Release number of selected component (if applicable): 1.5.3-13 How reproducible: Without fail Steps to Reproduce: 1. Use screen and graphics card capable of 1920x1200 2. start system-config-display 3. Actual results: 1920x1200 is not available Expected results: 1920x1200 should be available Additional info: Monitor is Samsung SyncMaster 2443BW Graphics card is nVidia GeForce4 MX 4000 use standard "nv" driver or the livna nvidia driver Digging through the source code it is clear that neither the vesamodes nor the extramodes files define any 1920x1200 modes. I have successfully added 1920x1200 at 60Hz to the xorg.conf file, but less persistent users will find this difficult. The 1920x1200 and other widescreen modes should be in the baseline set of modes.
Can you post your /var/log/Xorg.0.log file please? If your VBIOS hasn't programmed the panel for 1920x1200 nv will reject the modes as it doesn't have the code to reprogram it, I'd say that's what's happening here.
Created attachment 346702 [details] Xorg.0.log log file This is the version that works in wide screen with the modified xorg.conf
Created attachment 346703 [details] xorg configuration The modified xorg.conf file that specifies the 1920x1200 widescreeen mode. Parameters derived from CVTd6r1.xls obtained from internet.
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
