I can try, but it does not looks like it can be upgraded. This laptop works fine on 14.10 and does not seems to be supported by Toshiba anymore.
For me most interesting in call stack is this: #4 0x0000000000000000 it's NULL, istn't? It looks like there is some callback, thread or signal catcher which is not initialized correctly, it is called and bad things happend. I'm not sure is this even traceable, maybe there is some compilation option which could help catch such jumps? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448775 Title: Unable to login after upgrade from 14.10 to 15.04 possible XOrg crash To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1448775/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
