[Mageia-dev] Switching VT when in GDM causes X11 quit with fatal error.

Thu Jul 28 13:25:43 CEST 2011

Hi,
+
+I'm not sure what the problem is as I've not had time enough to debug
+properly.
+
+Booting with regular init or systemd, if you switch VT to text console
+and back again causes X to quit with a fatal error:
+
+[   105.480] (II) AIGLX: Resuming AIGLX clients after VT switch
+[   105.480] (WW) intel(0): drmSetMaster failed: Invalid argument
+[   105.480] (EE) intel(0): failed to set mode: Permission denied
+[   105.480]
+Fatal server error:
+[   105.480] EnterVT failed for screen 0
+[   105.480]
+[   105.480]
+Please consult the The X.Org Foundation support
+         at http://bugs.mageia.org
+ for help.
+[   105.480] Please also check the log file at "/var/log/Xorg.0.log" for
+additional information.
+[   105.480]
+
+
+Now I'm not 100% sure but if I run:
+setfacl -m user:gdm:rw- /dev/dri/c*
+
+before switching back then X does not crash. This could just be a simple
+race condition - X trying to do fancy DRI stuff before console-kit has
+had the chance to change the active session and add the ACL accordingly,
+but some other input on this problem is welcome.
+
+
+Note: systemd doesn't seem to give me a console login - so this is only
+with regular init - I presume I need to add a symlink somewhere to get
+regular console logins with systemd :) I'll look into that later.
