enable() and disable() are implemented at the extension's discretion. So
a buggy extension may be running code still (or already crashed) even
when told to disable itself. That's why we need to delete extensions as
much as possible here. That's not as easy with the Ubuntu extensions
because they are system requirements and removing them risks auto-
uninstalling the entire desktop.

I mentioned wallpapers because those potentially need "slicing" in Xorg
due to Xorg not having separate textures per monitor. It has one texture
covering all desktops which risks exceeding the maximum texture size for
the GPU. But that problem only exists in Xorg, not Wayland.

Just disabling d...@rastersoft.com should be enough as a first step.

Please also run this in a Xorg session:

  xrandr --verbose > xrandr.txt

and attach the resulting output here.

Title:
  Ubuntu 24.04 (X11) sometimes logs in to a black screen with only an X
  cursor

Status in gnome-shell package in Ubuntu:
  Incomplete

Bug description:
  I recently upgraded from Ubuntu 22.04 to Ubuntu 24.04. Now whenever I
  log in, sometimes I'll get a blank screen. It will only show the mouse
  cursor as an X.

  The problem seems to be intermittent. So far it's only happened to me
  using X11.

  My current workaround:

  1. Open another terminal (e.g. Ctrl+Alt+F6)
  2. Restart gdm3 (sudo systemctl restart gdm3)

  This seems to be affecting many people, although I couldn't find an
  existing bug: https://askubuntu.com/questions/1514757/issue-with-
  ubuntu-24-04-black-screen-with-cursor-on-login
