Title:
LightDM (?) blank/white screen after resume from suspend
Status in linux package in Ubuntu:
Invalid
Bug description:
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.
