Title:
  Suspend unreliable (possibly FUSE related)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Since updating to Focal my laptop stopped suspending reliably. It will
  sit there either without display or with the desktop stuck for almost
  a minute before it goes back to work again.

  Looking at the kernel logs this seems to be related to a FUSE mount
  that I have running:
