The backtrace shown here is stuck waiting for getpwnam() to finish, because (I assume) we're trying to add the acl rule allowing the authenticated user to add the screen. Thing is, gdm doesn't _do_ that on unlock, just at server setup. So I think what's actually happening is, the server _is_ really crashing on unlock for some reason, the log you've attached here is from the server launched to replace it, and the stall in getpwnam is because your network config has changed from under you and your NIS server or whatever is no longer accessible. There's not a lot X can do about the network going away from under it, but if it really is crashing on unlock that can be fixed. When this occurs, do you see a /var/log/Xorg.0.log.old file with a real crash backtrace at the end? Thanks Adam for looking into this and sorry for not replying before. I have actually been unable to reproduce the bug for the past few weeks. Maybe a recent update have managed to fix it. If it reappears I'll let you know, but I think the bug report can be closed for now. After evaluating this issue, there are no plans to address it further or fix it in an upcoming release. Therefore, it is being closed. If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened. |
