I have the flickering with the radeon driver, a Mobility FireGL 5200 and dual monitor setup. The flickering was on latest intrepid (with backports repository) and still is there on an up-to-date jaunty. I could correlate the flickering of my external monitor to screen activity. When I do nothing, the screen flickers almost not at all. When I move a window, or switch between virtual desktops, the screen flickers more often. When I run glxgears, the monitor stays blank until I quit glxgears. Also, disabling desktop effects improved my situation. With radeonhd, the screen does not flicker at all.

Hi Everybody: I think there is a solution without killing krunner.

The flickering is gone and I can use krunner, yay!

[Bug 278471] Re: Screen flickers or blanks every 10 s with KDE4
I can confirm that killing krunner fixes this, disabling KRandR does not. Also, the bug only seems to occur while the mouse is moving (screen blinks every ~3 seconds). In general it only blinks occasionally if the mouse is motionless, even if the keyboard is being used. After adding a script to ~/.kde/Autostart/ that executes `pkill krunner`, it now only seems to blink a few times while KDE is starting up. Does anyone know what it is about krunner that causes this? Also, this bug seems to be mainly about the KRandR issue.

You know, I'm really pissed. That KRandR kded module (aka Detecting RANDR (monitor) changes) is *not* in KDE proper but only in an obviously unfinished working branch of the KWin lead developer, Lubos Lunak. See http://websvn.kde.org/branches/work/~seli/randr/module/?revision=864812 for the current location and contents of that code. Congrats to Kubuntu for including unreleased code that explicitely specifies critical sections as HACK, well done. The last commit (6 weeks ago) even disabled that timer, quote: (...) #if 0 // xrandr apparently can't detect hw changes and on some systems polling freezes X :( QTimer* timer = new QTimer( this ); timer-start( 1 ); // 10 s connect( timer, SIGNAL( timeout()), this, SLOT( poll())); #endif (...) I suggest you people update the package to current SVN and leave it with that for Intrepid, so that not more damage is done than has already been inflicted. It won't work for events that happen during a KDE session then, but at least it doesn't break lots of systems in various subtle and annoying ways.

Same problem here, but killing kded4 doesn't help, neither does disabling the xrandr service. Instead, I found out that killing krunner works to fix the problem, but then I'm left without the program launcher. -- Screen flickers or blanks every 10 s with KDE4 https://bugs.launchpad.net/bugs/278471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi crwl, Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well. ** Changed in: xserver-xorg-video-radeonhd (Ubuntu) Status: New = Incomplete -- Screen flickers or blanks every 10 s with KDE4 https://bugs.launchpad.net/bugs/278471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 278471] Re: Screen flickers or blanks every 10 s with KDE4
Same problem here, ilowman and dipsol's fix work. I would describe it as flickering though, it's more like every 10 sec. or so the mode of the monitor is changed. I think the randrmonitor module queries the VGA port every time which results in the flickering. For example, if I run xrandr (from shell) without options to see what is connected, I get the same result. -- Screen flickers or blanks every 10 s with KDE4 https://bugs.launchpad.net/bugs/278471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Like Terry, I was also affected by this bug in the form of jerking of video playback every 10 sec. (or, jerking of konqueror auto-scrolling). Affected video driver was intel, and the chip 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) Since I don't have a physical tv-out connector in my laptop, I disabled the monitor-TV in the xorg.conf, which cured this issue for me. -- Screen flickers or blanks every 10 s with KDE4 https://bugs.launchpad.net/bugs/278471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks to ilowman and dipsol. It's a temporary fix and it flickers when KDE is booting up, but at least it's not doing it all the time now. -- Screen flickers or blanks every 10 s with KDE4 https://bugs.launchpad.net/bugs/278471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 278471] Re: Screen flickers or blanks every 10 s with KDE4
Upgraded 8.04 to 8.10 on an Acer Extensa 3100 laptop with 915/910-based graphics. After logging into KDE 4 I've got the same repeated flickering of the internal LCD display every ten seconds until I disabled KDE4's detect RandR (monitor) changes. As described above, manually calling XRandR command line tools causes flickering while the driver tries to detect which displays are currently connected. -- Screen flickers or blanks every 10 s with KDE4 https://bugs.launchpad.net/bugs/278471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 278471] Re: Screen flickers or blanks every 10 s with KDE4
Matthias: One more thing to consider, according to https://bugs.freedesktop.org/show_bug.cgi?id=16224 : If I'm not mistaken, EDID transfers are done in-band and thus will cause the monitor to lose sync. There's really no way around it. From the recent thread on the mailing list, it sounds like the solution is to fix GTK to not rely so heavily on calls to XRRGetScreenResources(). Disabling TV out did not fix the problem for me. Disabling KDE's randr service did, though obviously this may not be the correct solution. -- Screen flickers or blanks every 10 s with KDE4 https://bugs.launchpad.net/bugs/278471 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
