I experience the same error several times a day. So far I haven't been able to identify what causes the problem, but in the past 4 days I had like 20 crashes. In these cases screen locks up for ~5 seconds than crash report window pops up, but otherwise I can continue to work. Every once in a while (once in every 2 weeks) I see total lockup of X.
I'm not sure, but the problems started to accur about the time when I encrypted my home. Chris, do you have your home encrypted? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1129679 Title: Server hangs preceded by "EQ overflowing."
