I'm seeing the same. I have /usr/share/X11/fonts/misc populated and xfs running, so I doubt that's the issue. This seemed to start after one of the recent Xorg-related updates. A bit of poking around reveals: Jun 13 12:53:26 localhost setroubleshoot: SELinux is preventing /sbin/pam_console_app ly (pam_console_t) "append" to /var/log/kdm.log (xserver_log_t). For complete SELinux messages. run sealert -l 1cd15cf9-2db2-474f-b591-3672779e05d9 Jun 13 12:53:28 localhost setroubleshoot: [program.ERROR] Can not handle AVC'S related to dispatcher. exiting setroubleshoot context=system_u:system_r:setroubleshootd_t:s0, AVC sco ntext=system_u:system_r:setroubleshootd_t:s0 Jun 13 12:53:29 localhost kdm: :0[9600]: IO Error in XOpenDisplay Jun 13 12:53:29 localhost kdm[9197]: Display :0 cannot be opened Jun 13 12:53:29 localhost kdm[9197]: Unable to fire up local display :0; disabling. Jun 13 12:53:42 localhost audispd[1798]: writev(6): Broken pipe printed to /var/log/messages on logout. After removing setroubleshoot-server and setroubleshoot I'm left with: Jun 13 13:02:42 localhost kdm: :0[2980]: IO Error in XOpenDisplay Jun 13 13:02:42 localhost kdm[2576]: Display :0 cannot be opened Jun 13 13:02:42 localhost kdm[2576]: Unable to fire up local display :0; disabling. I've had the same issue: kdm starts up fine but stops after logout. I also have the selinux error, but it is unrelated to this issue. The issue (of me) is a crash of xfs: somewhere during the logout, xfs crashes and it is impossible to restart it. In my case, this was because my /tmp was a symblink to a directory on a partition which was mounted with options nodev,nosuid,noexec. After removing the symblink and creating /tmp in standard way, no xfs problems anymore. While trying to log in using xdmcp and kdm (see bug #243560), I wound up with complaints about the fixed font missing. After installing: xorg-x11-fonts-100dpi xorg-x11-fonts-75dpi xorg-x11-fonts-base and restarting xfs, this problem appears to have disappeared for me. I believe I have a simple method to reproduce this now. Simply stop and disable the xfs daemon. There may also be a need to remove any FontPath references in xorg.conf. I'd also removed all the xorg-x11-fonts-* fonts installed, but that seems to have no bearing on this. For me, logging out after doing this results in X/Kdm failing to restart. Starting the xfs service again returns things to a working state. Reassigning kdebase -> xfs. xfs shouldn't be dieing, period (imo). Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. We will review this issue again once you've had a chance to attach this information. Thanks in advance.

While preparing these files I noticed the KDE session in use became nearly unresponsive, taking 10-30 seconds to respond to user activity. Oddly, mouse movement seemed to help. Created attachment 158646 [details]

(In reply to comment #7) > Reassigning kdebase -> xfs. xfs shouldn't be dieing, period (imo). For the recored - in my case xfs IS NOT DIEING. I have noticed that after doing: # telinit 3 # telinit 5 I am able to login (no xfs restart during the above). Re-assigning back to kdebase... Anyone seeing this *not* on x86_64? anyone still seeing this, please make sure you have base-x installed: yum groupinstall base-x and try to reproduce. It seems to work now. I've found out that xorg-x11-fonts-base makes a difference but I don't know why it wasn't installed in the first place. OK, thanks for confirming. |
