Bug description:
  [Impact]

  The Nvidia driver corrupts and/or forgets its textures when resuming
  from suspend, by design. Documented here:

  https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt

  *NOTE* that this is actually not a common problem because the system
  must be using Nvidia as the primary GPU to be affected. So generally
  only desktop users will encounter the bug, not laptops. And even then,
  only desktops that use suspend/resume or VT switching may trigger it,
  if ever.

  Some components of the desktop implement the OpenGL extension which would signal that it is necessary to re-load the textures into memory.
  Some other components, namely GTK4 and Flutter applications, do not  implement this extension, and thus display graphical artifacts after resuming from suspend.

  To address the problem at a driver level, we are going to enable the
  driver option "PreserveVideoMemoryAllocations", which saves the GPU
  video memory contents to disk before suspending and uploads it back to
  the the GPU upon resuming.

  There is no risk of other processes messing with the stored memory
  contents, because it is saved to an unlinked file, and only the driver
  has its inode open.

  [Test Plan]

  1. Set up Ubuntu 24.04 on a desktop machine with an NVIDIA GPU
  2. Install the driver version being tested, for example:
     $ sudo apt install nvidia-driver-570
  3. Reboot the system
  4. Log-in to Ubuntu
     + Ensure that you logged-in to an X.org session, by verifying that
       `echo $XDG_SESSION_TYPE` returns the string "x11"
  5. Open Nautilus and App Center
  7. Suspend the machine
  8. Resume
  9. Verify that the previously opened Nautilus and App Center windows do not show
     any graphical artifacts

  [Where problems could occur]

  When testing in Sept 2024, the "PreserveVideoMemoryAllocations" feature was found to be broken on some kernel/driver version combinations.
  The driver would crash upon resume, locking the system, possibly even preventing ssh access. The only recovery option would be to forcefully reboot the system.

  [Original Bug Report]

  I recently installed ubuntu 20.04 on my computer, and I am running
  into an issue when I do the following:

  * Login with a user on desktop
  * Select switch user, and login as second user
  * Switch user again, and return to original user

  At this point, text and icons in the menubar / sidebar are corrupted.
  Text and icons in normal windows appear correctly. I have attached a
  screenshot of what this looks like.
