Title:
  Screen garbled on login and freezes on unsuspend

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  1. The login manager works but as soon as I log in, the screen is
  filled with colored vertical stripes and is unusable.  I found that if
  I change the screen resolution to the maximum (1920x1080), then the
  screen is ok.  Any other resolution that I've tried (eg (1440x900 used
  to be my preference) causes the unreadable display and it does not
  revert back, requiring a reboot.

  2. Coming out of suspend, the password entry screen is displayed, but
  there is no response to keyboard or mouse, requiring a reboot.

  HP Envy x360 laptop with AMD Ryzen 7 with Radeon graphics

  Last known kernel that worked is 5.11.0-46
