Description of problem: For the last month or so, running rawhide on a Vaio SZ3 laptop I see occasional flickering of the whole screen in X. At moments when the system is very highly loaded, it is apparent that all screen elements are being redrawn, slowly. Version-Release number of selected component (if applicable): xorg-x11-drv-i810-2.2.1-14.fc9.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3.

There is a related problem in which the X screen goes black (not completely blank, as the LCD is still active). May be worth a separate bugzilla report.
I've seen this too, I know that there is bug 435747 regarding the backlight going off, particularly after suspend/resume, but I've not tried to suspend my laptop since installing rawhide on it yesterday :)
You can probably work around this by adding: Option "FramebufferCompression" "False" to your 'Device' section in your xorg.conf. See https://bugs.freedesktop.org/show_bug.cgi?id=13326
Should be fixed in xorg-x11-drv-i810-2.2.1-20.fc9 by forcing FramebufferCompression off by default.
Re-opening this bug because I've installed the mentioned version, having removed the explicit mention of FramebufferCompression in xorg.conf and there is still occasional flickering, at least on my hardware.
I can confirm screen flickering after resume from suspend, maybe framebuffer compression resets to on? My "Device" section is as follows: Section "Device" Identifier "Videocard0" Driver "intel" Option "AccelMethod" "exa" Option "MigrationHeuristic" "greedy" Option "ExaNoComposite" "false" EndSection Intel driver is xorg-x11-drv-i810-2.2.1-20.fc9
An update - I've just installed xorg-x11-drv-i810-2.2.1-21.fc9.x86_64 and the Xv problem mentioned in other bugs is solved but the whole screen flickering returns if I use compiz instead of metacity.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Created attachment 305838 [details] Trailing section of Xorg.0.log which is appended repeatedly (In reply to comment #10) > *** Bug 446615 has been marked as a duplicate of this bug. *** Bug 446615 is about an ATI Radeon X800 card using the "radeon" driver, not the "intel" one. In my case, the attached text block is appended to Xorg.0.log over and over again. It suffices to launch some GNOME application to trigger the flicker [a plain X application does not do this]. Accordingly, the number of copies in Xorg.0.log quickly reaches a three digit figure in a short period of time. I really wonder how bug 446615 would be a duplicate of the present one. The symptoms are fairly different. I would rather suspect a RANDR (applet) malfunction.
Created attachment 306927 [details] Xorg.0.log for HP A4576A attached to ATI Radeon X800 SE (R430) No improvement for the latest koji build xorg-x11-drv-ati-6.8.0-17.fc9. Xorg.0.log shows a trailing section about registering and removing a "DVI-0:ddc2" device. Said section is repeated over and over again, and only the first one has been kept in the attachment which otherwise contains the full Xorg log. In fact, no display is connected to the DVI output, only an analog CRT model HP A4576A to VGA-0. Executing 'xrandr -q' returns: ------------------------------------------------------------------------ Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 1920 x 1200 VGA-0 connected 1400x1050+0+0 (normal left inverted right x axis y axis) 364mm x 291mm 1400x1050 85.0*+ 74.8 70.0 60.0 1920x1200 60.0 1920x1080 59.9 1600x1200 85.0 75.0 75.0 70.0 65.0 60.0 60.0 1680x1050 84.9 74.9 69.9 60.0 59.9 1600x1024 60.2 1400x1050@75 75.0 1280x1024 85.0 85.0 73.7 75.0 60.0 60.0 1440x900 59.9 1280x960 85.0 60.0 1360x768 59.8 60.0 1152x864 100.0 85.1 85.0 75.0 75.0 70.0 60.0 1024x768 85.0 85.0 75.1 75.0 70.1 60.0 832x624 74.6 800x600 85.0 85.1 72.2 75.0 60.3 56.2 640x480 85.0 85.0 75.0 72.8 75.0 60.0 59.9 720x400 85.0 70.1 640x400 85.1 640x350 85.1 None disconnected (normal left inverted right x axis y axis) DVI-0 disconnected (normal left inverted right x axis y axis) ------------------------------------------------------------------------ So, which component should this bug get assigned to? Certainly not xorg-x11-drv-i810, as this is a more general issue.
An update - the flickering starts happening again if I switch to compiz with xorg-x11-drv-i810-2.4.2-8.fc10.x86_64 on Rawhide.
Same problem here on F10 rawhide: xorg-x11-drv-i810-2.5.0-3.fc10.i386 (Dell Latitude D610 w/ intel gma915)
I confirm the bug. Fedora 10 fully updated. Same hardware: Dell Latitude D610, intel gma915
I also can confirm the bug on an Acer Aspire 3610 with intel gma915. F10 fully updated. intel driver has the blinking and some issues with scaling the video for an attached projector. the i810 driver (which I used to use) doesn't work at all...leaves me at a blank black screen with a single blinking cursor in the top left with no fallback to runmode 3 like what used to happen when the wrong driver was chosen. Just an idea: If driver wierdness (although different in each case) is present with both drivers, is it perhaps something in the kernel? Complete disregard to this noob comment is expected.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. 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 '9'. 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 9'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 9 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 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
