Title:
lightdm crashes during normal operation with no obvious cause
Status in lightdm package in Ubuntu:
New
Bug description:
This has happened several times in the last few weeks, including twice
yesterday. 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.
