I've created another user with no applications running at all and still have the desktop covered in black.
I have tried running xwininfo and get the display I attach. ** Attachment added: "xwininfo display" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1970141/+attachment/5584749/+files/Screenshot%20from%202022-04-28%2021-02-43.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1970141 Title: Desktop is mostly covered by a black rectangle Status in gnome-shell package in Ubuntu: Incomplete Bug description: Hi I'm running Ubuntu 20.4 with the Apr 20 updates applied. gnome-session: Installed: (none) Candidate: 3.36.0-2ubuntu1 Version table: 3.36.0-2ubuntu1 500 500 http://gb.archive.ubuntu.com/ubuntu focal/universe amd64 Packages 500 http://gb.archive.ubuntu.com/ubuntu focal/universe i386 Packages gnome-shell: Installed: 3.36.9-0ubuntu0.20.04.2 Candidate: 3.36.9-0ubuntu0.20.04.2 Version table: *** 3.36.9-0ubuntu0.20.04.2 500 500 http://gb.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 100 /var/lib/dpkg/status 3.36.4-1ubuntu1~20.04.2 500 500 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages 3.36.1-5ubuntu1 500 500 http://gb.archive.ubuntu.com/ubuntu focal/main amd64 Packages I accept that this is "cosmetic" but it's still annoying. I have two large monitors attached which I run as a large single workspace across both screens. I have been running this for years without problem over several Ubuntu releases. Following the recent upgrade (Apr 20 2022), my desktop wallpaper is no longer displayed properly. Almost all of it is covered in solid black except for a very small sliver of the wallpaper at the bottom of each screen. If I change the desktop background there is no effect (except for the small sliver at the bottom of the screen) changes. If I reboot, or if I log in as a different user, there is no change. If I click "Activities" or press the Windows button, the menu of desktops I can switch to is displayed with the correct wallpaper, but when I switch to it it comes out all black on both screens (apart from the icons, any windows and the sliver at the bottom of the screen). I have 2 different laptops which I have upgraded also but those are OK. I've not tried any dual-screen on them. Possibly relevant is that I have an nVidia display controller. It does appear to be a problem that has crept in with the most recent update. Everything else I do is unaffected as far as I can see but I'd just like something different from the boring solid black.
