Public bug reported: I have posted related report to X.Org https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/638871 (some logs available) But then I have found this bug in mesa.
After KDM-login X-Server will be restarted. I have downgraded from "7.9~git20100909-0ubuntu1" to "7.8.2-2ubuntu2" and it works again and I can start my KDE. ** Affects: mesa (Ubuntu) Importance: Undecided Status: New ** Tags: kde kdm kubuntu -- X crashes after KDM in the new version of mesa https://bugs.launchpad.net/bugs/639812 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
