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, if available) 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 (if you have one) 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.

Xorg.0.log from latest git has regression too
Still a problem on Fedora 11. $ rpm -q xorg-x11-drv-ati xorg-x11-drv-ati-6.12.2-14.fc11.i586 I found a workaround though, maybe this will help in fixing this bug too? xrandr --newmode "1920x1200_60.00" 162 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync xrandr --addmode DVI-0 1920x1200_60.00 xrandr --output DVI-0 --mode 1920x1200_60.00 xrandr --output DVI-0 --right-of LVDS I should note the flickering *only* happens when I set my monitor to native 1920x1200 resolution as exposed through xrandr. $ xrandr --output DVI-0 --mode 1920x1200 If I choose 1680x1050 there is no flickering. However using the custom 1920x1200 modeline I mentioned in comment #4 fixes the flickering. Using the latest from rawhide things have gotten worse. The external 1920x1200 DVI display does not even come on to flicker anymore. It just stays black. And using the previous workaround from comment #4 doesn't work anymore. $ uname -a Linux localhost.localdomain 2.6.31.5-112.fc12.x86_64 #1 SMP Tue Nov 3 00:28:52 EST 2009 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/redhat-release Fedora release 11.92 (Rawhide) Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command yum upgrade --enablerepo='*-updates-testing' Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD . Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you. If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you. [This is a bulk message for all open Fedora Rawhide Xorg-related bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.] (In reply to comment #7) > Please, if you experience this problem on the up-to-date system, let us now in > the comment for this bug, or whether the upgraded system works for you. I have tested again with a newer build, desktop-i386-20091104.16.iso, and the problem still exists. There are two cases here 1. booting with KMS (the default) On boot my secondary DVI display does not light up at all. No flickering or anything. The green status light on my monitor doesn't even come on to indicate a signal. I'm left with no way of logging in because the GDM puts the login on the dark screen. (This was the the same case from comment #6) 2. booting with 'nomodeset' kernel option On boot the secondary DVI display lights up but flickers very badly just like my original bug report. Adding a custom modeline as in comment #4 fixes the flickering. I'm not sure how you want to handle this bug. Ignore the 'nomodeset' case and just focuss on getting it to work with KMS? From my comment #8, the first case looks like bug #421982 (and presumably duplicates bug #484992 and bug #522238). Situation, the secondary DVI output does not light up monitor when using KMS. Using VGA connection instead *does* light up monitor with KMS. Sorry, s/bug #421982/bug #521982 I've filed a new bug #544018 to cover case #1 (booting with KMS) from comment #8 This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. 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 '11'. 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 11'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 11 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 Improving summary. --- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers [This triage is part of collective effort done by students of University of Rijeka Department of Informatics.] This is fixed in F13. Great! Thank you for reporting back. |
