[Launchpad Bug Tracker <1456531@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

On Xubuntu 15.04, when I suspend the machine and resume afterwards, the
screen remains completely white/blank. I can move the mouse cursor, but
I don't see any screen elements. Clicking or wildly pressing keys
doesn't do anything.

I can switch to a different console with Ctrl+Alt+F1 and log in, just
fine.

For this bug report, I have removed all files from /var/log/lightdm,
then rebooted, suspended, resumed, and switched to VT1. Then copied the
/var/log/lightdm files to a different location. See their contents
attached to this bug report.

Other parameters:

- Simply locking and unlocking the screen works, ALTHOUGH I also see the
white screen there at first, and have to click a mouse button for the
login form to show up.

- I'm running a system with a fully encrypted hard-drive and have
configured LightDM to log me in automatically.

- System is up-to-date.

- No experimental packages, although I had an experimental version of
xserver-xorg-video-intel running, but removed it shortly after.

- System is a Thinkpad T450s with Intel HD 5500 graphics.

Hope I didn't forget to mention anything important. If you need more
information or want me to try something, let me know.
