Bug description:
  In disco; I have this issue where my external monitor (a ThinkVision
  P24h-10) connected to my ThinkPad T480s turns off for short times
  while actively working on the system. I noticed that if I don't move
  my mouse at all while it's off, it stays off.

  The T480s is connected to the monitor via USB-C; the monitor provides
  DP, USB, and Power over that connection. When the display turns off,
  USB devices continue working.

  I have attached /sys/debug/dri/0 output from when the monitor was off
  (a) vs on (b).

  Other related bits:
  * This also happens on HDMI, but much less often
  * There are no log messages when the display turns on/off in the journal.
