Description of problem: The custom ModeLine I've been using in previous fedora releases is utterly ignored by the radeon driver in Fedora 8. There appears to be a patch for this over in the xorg bugzillas: https://bugs.freedesktop.org/show_bug.cgi?id=10205 Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.7.195-3.fc8 How reproducible: Totally Steps to Reproduce: 1. Try to specify ModeLine 2. Find no evidence in X log that it was ever seen 3. Actual results: see above Expected results: I'd love to have my custom mode working so my stoopid (probably hardware bug related) radeon card will stop flickering. (Although I've actually gotten tired enough of the flakey hardware to order a new video card, so I may not care as much about this soon :-). Additional info: Anyone interested in the full history of my ModeLine can read: http://home.att.net/~Tom.Horsley/easy-linux.html
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. We will review this issue again once you've had a chance to attach this information. Thanks in advance.
Sorry, I solved my problem by swapping out the radeon card and swapping in an nvidia, so I can no longer get any new information relevant to the radeon driver :-). I can say, that it had no problem auto-detecting the EDID info for the monitor and driving it with that mode, unfortunately the monitor didn't actually work correctly with the input it asked for, which was why I wanted to use my own mode line running at a lower refresh rate. In the easy-linux.html web page link above, I had to disable DDC to get it to accept my custom ModeLine. I have a deep suspicion that the problem in the latest fedora 8 X server is that the DDC module is now built in and there is no way to turn it off. Unfortunately, that's about the most info I can provide.
Thanks, I will pass your thoughts to developers, and we'll see what they will do about it (moreover, note, that in Rawhide and thus Fedora 9, Xorg is completely rebuilt, so this whole issue may not be relevant for further development anymore; of course, we should fix in F8 anyway).
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. 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 '8'. 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 8'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 8 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 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
