Team moved to a new floor; system power was removed while I was at lunch (ugh). Powered on at new location, logged in, and... the desktop environment stated failed to start session "cinnamon".

I have tried:

  1. update packages sudo apt-get update && sudo apt-get upgrade
  2. uninstalling and reinstalling nvidia-375
  3. uninstalling and reinstalling cinnamon
  4. installing cinnamon-desktop-environment
  5. uninstalling, reinstalling, and resetting compiz settings

After #3, the error message went away, but the desktop environment never loaded. Instead, I just get my background image. No desktop icons, no taskbar, no user interaction at all.

The only thing I can do is load up a different console control-alt-F1 and do stuff from there. At this point, I'm not sure where to go to try to solve this. Any thoughts/helps/hints?

System configuration:

i7-6850K 32GiB RAM NVMe SSD Nvidia GTX 1060

Ubuntu 16.04 -- no Unity junk, only Cinnamon.


For what it's worth, I feel like an idiot...

I just now (after 5 hours pulling my hair out) thought that maybe the GPU was jostled during transit to the new floor. So I reseated the GPU.

Finally... the desktop environment loads.

Of course it's been reset (I now need to reset my theme settings, re-add icons to the tray, etc) but... it works yay.
