Created attachment 478979 [details] dmesg output Description of problem: After upgrade from Fedora 13 to Fedora 14 the screen of my notebook is flickering after starting with grub, while my external monitor (24", HDMI) is still fine. The monitor is still flickering, when the login-screen appears. When I press the Fn-Screen button some times, the notebook is changing the display configuration and after some presses, both monitors are available in the right configuration without flicking. I thought it might be a problem with the kernel-mode-setting, because its also flickering during the boot process. Version-Release number of selected component (if applicable): Kernel: 2.6.35.11-85

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 add drm.debug=0x04 to the kernel command line, restart computer, and attach * your X server config file (/etc/X11/xorg.conf, if available), * X server log file (/var/log/Xorg.*.log), and * output of the dmesg command (after the issue happens and before reboot), to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above. We will review this issue again once you've had a chance to attach this information. Thanks in advance.
Same card (AGP though), similar problem. Adding "radeon.new_pll=0" fixes the flickering but disables 3D acceleration. Will try with a Fedora 15 Alpha to see what "drm.debug=0x04" says...

Hello, I attached the files with "drm.debug=0x04" enabled. After the times flickering including login-screen, now the flickering is only there during boot-process some times, but not too often. When the login-screen comes up, there is no flickering anymore. I also tried to reproduce the failure without drm.debug, but there is still no flickering at the login-screen anymore. Sincerely, Tobias

This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached 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, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. 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
