/tmp unwriteable after upgrade to intrepid beta, resulting in failure of graphical login

[Ernst Kloppenburg]

after doing the upgrade to intrepid beta (today), logging in via gdm failed with the message "your session lasted less than 10 seconds, ..."

The .xsession-errors log has
    mkdtemp: private socket dir: Permission denied

The reason was /tmp being unwritable
   drwxr-xr-x 14 root root 12288 2008-10-12 19:27 /tmp/

I could fix the problem with chmod go+w /tmp

But did not reboot since, maybe the fix does not persist.

Thank you for taking the time to report this bug and help make Ubuntu better, however there isn't enough information in this bug report to help diagnose the problem, can you tell me if this fix does persist after reboot? Can you tell me what packages were updated? Did you reboot cleanly, or did you hard reboot?

- what packages were updated? About 1000 :-)
- I did reboot cleanly (reboot initiated by the dist-upgrade tool)
- my fix does persist after reboot
(sorry, my next opportunity to contribute so finding the problem will be wednesday night GMT)

I also got this error. I ran 'sudo chmod -R 777 /tmp' and it seem to work.
