The problem goes away once the X server is restarted. Adding "sleep 5" to /etc/init.d/xdm also makes the problem go away.

https://bugzilla.novell.com/show_bug.cgi?id=658788 https://bugzilla.novell.com/show_bug.cgi?id=658788#c3 --- Comment #3 from Vladimir Klebanov 2010-12-11 20:53:28 UTC --- The problem is I don't understand it well enough, but I'll try. Apparently, the problem is that X comes up "too early" while the VT7 is in an "error state". In Ubuntu this was due to another component (cryptsetup probably) "stealing" the terminal. Comment #92: --------------------------------------------------------------

...

The last thing I noticed before my shiny new SSD died a horrible death today was that the problem would go away if I commented out the line "console owner" in /etc/init/cryptdisks-enable.conf.

That precisely fits the problem definition. "console owner" while X is running while forcibly take the ownership of tty7 away from X. It doesn't like that so much (cf. this bug) -------------------------------------------------------------- That's my understanding - it could be wrong though.

You mean diagnose the culprit? Honestly I don't know. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
