[buzzmandt]

I haven't found a fix for this and am having the same problem.

No solution, just a poke in what may be a useful direction...

What does /var/log/kdm.log say after this happened?

[buzzmandt]

after restarting x and logging back in this is all there is in kdm.log

same problem here but its known issue i hope that can be resolved by a normal update
the only workaround i found us this :
Cntl-Alt-F1 for a console and run sudo stop kdm; sudo start kdm for a workaround.

look at this link : https://wiki.ubuntu.com/KarmicKoala/Beta/Kubuntu ;)

There's a bug in the Intel video driver that causes this. It's been fixed in a recent commit, but you'd need to use the xorg-edgers ppa or compile the driver yourself to get a driver updated to it.

Will Karmic get the 2.9.0 version of the driver? If not, this bug will probably stay throughout Karmic's lifetime (save backports). The workaround is to change /etc/kde4/kdm/kdmrc to have X terminate the server and restart a new one when logging out, instead of trying to reuse the same process (regeneration).

Find the line TerminateServer in the [X-*-Core] section and make sure it's uncommented and set to true.

[...] this is a known breakage. We don't
recommend that people run with regeneration though...

[...]

It's usually a display manager (gdm or kdm) option. On gdm it's
AlwaysRestartServer, on kdm it might be AllowClose=true (not sure about that).

Basically what you want to do is start a new X server everytime, rather than
trying to reuse the server you just logged out from.


I found the settings

add TerminateServer=true
to /etc/kde4/kdm/kdmrc under [X-*-Core]

Now log off works.

Comment #19 From Keith Packard 2009-09-17 18:20:14 PST -------

Fixed in commit 33f98e4056706f4c30bb4327677ac49e82058231 by leaving GEM running
across server reset.

http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=33f98e4056706f4c30bb4327677ac49e82058231

Don't destroy bufmgr at CloseScreen time

Under KMS, the bufmgr is not initialized at InitOutput time and so it won't be re-initialized during server regen. Thus we must leave the bufmgr running during regen and cannot destroy it in CloseScreen. Under UMS, each place the bufmgr is initialized, it checks to see if it has already happened. Hence, we can safely leave the bufmgr running across server regen for UMS too.
