Having installed the ssh package, when I get the lockup behaviour noted above, I can login, viar secure shell, to the machine.
Also noticed a bunch of these in /var/log/messages: [drm] nouveau 0000:03:00.0: PFIFO_DMA_PUSHER - Ch 2 [drm] nouveau 0000:03:00.0: PFIFO_CACHE_ERROR - Ch 2/1 Mthd 0x1c3c Data 0xfff47d4d -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/701532 Title: setting monitor positions only sort-of works -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
