Hmm, I'm still seeing this with an apparently up to date 14.04. It's an Acer Aspire 1301 which until I installed 14.04 (fresh on SSD) was working fine. What I have noticed is that I can now only use the Nouveau drivers - the Nvidia ones are hopeless - crashes with major rendering issues almost straight away. Again, all was fine prior to 14.04.
The death is infrequent - can use for a couple of days over multiple simultaneous logins, then get a lock when switching users. alt-ctrl-f1 drops me back to a terminal, alt-ctrl-f7 back to the frozen display. So next time it happens, what is the best way of capturing a log? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1247189 Title: Ubuntu freezes completely when switching user To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1247189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
