apport information ** Tags added: apport-collected vivid
** Description changed: 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. + Hope I didn't forget to mention anything important.
