Well, I've looked at the crash dump and I'm not sure what symbols gdb can't find. I've loaded debug symbols for compiz-core and it still complains, so I'm at a loss.
I have been reading up on what the kernel trap means and basically it's saying that a process is performing something the hardware doesn't like. In cases like these, the driver is supposed to tell Compiz if something is supported or not, but apparently it's not. It's possible that the newer drivers are making an assumption about the underlying hardware. Your BIOS may be outdated which may fix some issues. Is it possible to try to update the BIOS on your machine and see if it helps? -- 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
