lxg, as per http://support.lenovo.com/us/en/products/laptops-and-
netbooks/thinkpad-t-series-laptops/thinkpad-t450s an update to your
computer's buggy and outdated BIOS is available (1.17). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status
Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.

Title:
  LightDM (?) blank/white screen after resume from suspend

Status in linux package in Ubuntu:
  Incomplete

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.
