I tested once so far. I have dual screen setup with monitor Samsung SyncMaster 2253LW and internal laptop monitor, which is turned off when booting (using KDE's Display Dialog setting)
The bug is reproducible usually on first or second boot per day -- I have to reboot because the system gets unusable. Then the monitor usually does not blink. But I decided to keep kernel 3.2.5 around. I noticed that the bug is still there after some series of kernel 3.3.x updates. Can I help somehow to identify the problem? I will try to test with Live Fedora 17 beta disk.
I have a similar symptom that may shed some light onto your situation. I am running Fidora 17 with an Invidia graphic card. Things work fine unless, I run the monitor through a KVM switch. With the KVM switch, the monitor is not properly detected, and the Invidia driver sets the resolution to a low resolution. Ever 20 seconds or so, it resets the monitor and tries again to identify the monitor. When it does the reset the screen goes blank for about 1 second. So I have a low resolution display that goes black every 20 seconds. Perfect..... I have been trying to find a solution to hard configure the monitor settings like in /etc/X11/Xorg.conf but my system has no such file. I am guessing the new version does not use such a file. I also looked at ~/.conf/monitors.xml which contains a complete monitor descriptor when I do not use the KVM switch, but I do not find a way to make it persist so I can boot with the KVM switch. Right now I must remove the KVM switch each time I boot. It sounds like the bug of this thread would also benefit from a fixed configuration instead of a sensed one. Can anyone shed some light on this?
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '16'. 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 16'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 16 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, you are encouraged to click on "Clone This Bug" 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
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 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.
