Since it doesn't look like the bug report includes it, my display information is:

There is no obvious user action that triggers the crash: the first crash yesterday, I was composing an e-mail in the GMail pop- out editor; the second I was editing a config file on a remote server via SSH; previously, the crash has happened while I've been just reading something on the screen, not interacting with the computer at all. The symptoms are a non-responsive display, with the exception of the mouse pointer. I'm not even able to switch to a different vt - just get a black screen. However, I *am* able to SSH into the machine, and when I did so yesterday I tried: * killing compiz * restarting the unity7 upstart job (my windows flashed briefly on the screen, then I got the login background) * restarting lightdm The latter action got me to a login prompt, where I was able to login and start a standard desktop session and, thankfully, resume my screen and tmux sessions and not lose any work.
