Description

I just found out that almost every action in GDM (including just moving the mouse) results in new DCC probe messages appearing in /var/log/Xorg.0.log, describing the attached monitor. Created attachment 374204 [details]
strace of Xorg during gdm user select
The only action performed during this strace was selection of a user name in the GDM login dialog by pressing Enter. The strace was terminated when the password selection dialog had appeared completely.
Created attachment 374205 [details]
xorg.conf (problem appears without xorg.conf, too)
Created attachment 374206 [details]
xorg.0.log
System is F12, but runs a rawhide kernel for testing. Problem also appears with kernel-PAE-2.6.31.5-127.fc12.i686.
All logs aboard. This bug has been triaged -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers *** Bug 542097 has been marked as a duplicate of this bug. *** The Xorg.0.log is very long with lots of repeated output of monitor detection. It's similar to https://bugzilla.redhat.com/show_bug.cgi?id=523646#c12 In https://bugzilla.redhat.com/show_bug.cgi?id=523646#c16 there is a report that kernel-2.6.31.6-145.fc12.x86_64 from updates-testing improves the situation. Since these two bugs look very similar, can someone here test that kernel too? I only get bad performance at the login screen, and for me 2.6.31.6-145.fc12.x86_64 does not exhibit this behaviour. For me the problem carries over to the desktop, and 2.6.31.6-145.fc12.PAE.i686 does not fix it (neither in GDM nor on the desktop) Hi, I reported this bug here https://bugs.freedesktop.org/show_bug.cgi?id=24556 a while ago. I closed it but I should not have : $ ls -lh /var/log/Xorg.0.log -rw-r--r-- 1 root root 115M nov. 30 17:12 /var/log/Xorg.0.log The bug still occurs with kernel 2.6.31.6-145.fc12 both at GDM login screen and while using firefox. There is a sysprof log in the bug I filed in freedesktop bugzilla. This was my description of the bug : "Xorg is very sluggish on my intel X4500HD graphic card. It's sluggish even in GDM at startup but it's worse when using firefox : it's getting slower and slower until X seems to be freezed and hard reboot is needed. The uncompressed Xorg log weights 15M. sysprof points to drm_do_probe_ddc_edid. I don't have a Xorg.conf and I don't use composition." Isn't this bug the same as https://bugzilla.redhat.com/show_bug.cgi?id=523646 ? It probably is. I noticed something else, which may be related, running F11 (fully updated, shared home dir) on the same hardware. Soon after starting GNOME the kernel starts triggering a flood of udev events relating to the graphics card: KERNEL[1259658330.187297] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1259658330.201980] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1259658330.209853] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1259658330.214514] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1259658330.218688] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) This just goes on and on. The system stays usable, though, it just triggers a ton of udev child processes. *** This bug has been marked as a duplicate of bug 523646 *** (In reply to comment #9) > I only get bad performance at the login screen, and for me > 2.6.31.6-145.fc12.x86_64 does not exhibit this behaviour. I think I was lucky. 50% of the time I get the slow behaviour. |
