Go to tty1 with `Ctrl`+`Alt`+`F1`.

Go back to desktop with `Ctrl`+`Alt`+`F7`

Screens stays blank. Cursor changes from an arrow to a hand. 

When I then close and re-open the lid the screen comes back up but is seriously garbled. I need to minimize all applications to make them proper. The desktop does not refresh though and requires logging out and in.

nvidia version 173 is active.

What is the best way of triaging this?
