Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
Blank Screen initiates then fails
Status in Ubuntu:
Incomplete
Bug description:
Blank Screen initiates after timeout (usually 5 minutes but set to 1
minute to replicate this bug), screen goes blank on both laptop and
external Dell, but immediately comes back on. Whilst it is blanking,
any running applications show their windows (which is not usual) but
it appears gnome-shell and the window manager are not running (no dash
and no window decorations).
Disconnecting external monitor exhibits the same Blank Screen failure
on the laptop screen.
I have turned Automatic Screen Lock off for now to remove that as a
cause.
I have also had intermittent failure of gnome-shell.
