As a follow-up, my system ran fine for a little bit with the fixes I mentioned in post #115, but then after a while the screen went black and I couldn't do anything but hold the power button in to power off.
The system wouldn't even reboot with Alt+SysRq - K, S, U, B... This is not very fun - I am trying to set up Ubuntu for a Windows user, trying to convert her, but if the system randomly crashes like this, the conversion is bound to fail. -- MASTER: [i855] GPU lockup (apport-crash) https://bugs.launchpad.net/bugs/541511 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
