Created attachment 749764 [details] Random pixels My XFCE desktop was filled by many random pixels. When a window is redrawed, most random pixels disappear. When I move a window, I get more random pixels. -- I tried kernel 3.7, 3.8 and 3.9: I have the same issue (random pixels in Xorg). I upgraded my Fedora recently, and I didn't have this issue before.
My GPU is "ATI Radeon HD 5570", and Xorg uses the radeon driver according to this Xorg log: [ 28.297] (--) RADEON(0): Chipset: "ATI Radeon HD 5570" (ChipID = 0x68d9) Driver version according to rpm: $ rpm -qi xorg-x11-drv-ati Name : xorg-x11-drv-ati Version : 7.0.0 Release : 0.9.20121015gitbd9e2c064.fc18 Architecture: x86_64 Install Date: mer. 06 mars 2013 01:14:23 CET Group : User Interface/X Hardware Support Size : 413992 License : MIT Signature : RSA/SHA256, jeu. 14 févr. 2013 17:19:03 CET, Key ID ff01125cde7f38bd Source RPM : xorg-x11-drv-ati-7.0.0-0.9.20121015gitbd9e2c064.fc18.src.rpm Build Date : jeu. 14 févr. 2013 16:19:04 CET Build Host : buildhw-02.phx2.fedoraproject.org Relocations : (not relocatable) Packager : Fedora Project Vendor : Fedora Project URL : http://www.x.org Summary : Xorg X11 ati video driver Description : X.Org X11 ati video driver. -- Which kind of information do you need to diagnose this crash?
Created attachment 749765 [details] Random pixels on desktop Another screen shot of my whole desktop (I have two screens) to see random pixels.
It looks like the crash is related to a new version of a mesa library. Downgrading mesa libraries fixed the issue: sudo yum downgrade mesa-{libGL,libEGL,libgbm,libglapi,dri-drivers,libGL-devel,libxatracker} llvm-libs
Logs of the downgrade: Supprimé : llvm-libs.x86_64 0:3.2-2.fc18 mesa-dri-drivers.x86_64 0:9.1-3.fc18 mesa-libEGL.x86_64 0:9.1-3.fc18 mesa-libGL.x86_64 0:9.1-3.fc18 mesa-libGL-devel.x86_64 0:9.1-3.fc18 mesa-libgbm.x86_64 0:9.1-3.fc18 mesa-libglapi.x86_64 0:9.1-3.fc18 mesa-libxatracker.x86_64 0:9.1-3.fc18 Installé : llvm-libs.x86_64 0:3.1-11.fc18 mesa-dri-drivers.x86_64 0:9.0.1-1.fc18 mesa-libEGL.x86_64 0:9.0.1-1.fc18 mesa-libGL.x86_64 0:9.0.1-1.fc18 mesa-libGL-devel.x86_64 0:9.0.1-1.fc18 mesa-libgbm.x86_64 0:9.0.1-1.fc18 mesa-libglapi.x86_64 0:9.0.1-1.fc18 mesa-libxatracker.x86_64 0:9.0.1-1.fc18
Created attachment 751369 [details] Xorg logs (after the downgrade) I'm using XFCE 4.10. The compositor is disabled.
I just had the issue again with the latest mesa and Xorg versions, 20 minutes after the boot, in XFCE. I connected to this desktop computer using a laptop through SSH to run "Xorg -retro :1". At the first try, I didn't see any random pixels, but it's hard to see them on the Xorg -retro background, so I'm not sure. At the second try (stop Xorg -retro and type again the command), I had also random pixels. I don't know what it does mean.
This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. 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 '18'. 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 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 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 change the 'version' to a later Fedora version prior to Fedora 18's end of life. 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.
I'm sorry, I forgot to close the issue. It was an hardware problem: I manually turned off the fan 2 years ago, but recently, the GPU started to bug. I fixed the issue by plugging again the noisy fan. I fixed again the issue by replacing the ATI by a fan-less Nvidia card :-) Sorry for the noise!
