X freezes after log out (network available)

[ndde]

When using the log out functionality of gdm X does not start up again. The system is stuck. The only way to access the system is via network, e.g. ssh.

When system is stuck the screen shows wired points on a mostly black screen.

Note that if i not click on log out the system works well.

Hello

/var/log/syslog

here you are

Hallo,

as far as i know dell-wmi has to do with hotkeys. The unknown keys that appear in dmesg are not related to this bug. they appeared in former ubuntu versions, too.

Hi,

reinstalled the 3 packages but the bug further exist.

I attach log-files that might be helpful.

[ndde (jannis-upb)]

Hi,

the problem lies in KMS. When turning it off [1] the problem does not occur. So i found a workaround.

Regards,

Now i tried to reproduze the bug using the radeonhd driver. Using this driver log out works fine. Contact me in case you need further information.

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version.Thanks in advance and sorry for the late response.
