Edit: I solved this using the command gsettings reset org.gnome.Settings last-panel

And it turns out I have the exact problem of this user: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/2017498 I just didnt know because everything in gnome control center didnt work. After resetting, I deliberately clicked on the mouse settings and it went bad again. Reset again and it works again.

Old Description (out of date, just for reference):

Hi! I'm trying to find out why my display settings are not showing when rightclicking or using gnome-control-center display.

I have recently disabled a mod I had done to disable pipewire since I couldn't hear anything when using rdp. But probably some of the changed configuration is now breaking parts of my system.

Here's the error message when using the above command:

GStreamer-Play[16682]:   ERROR: GtkGstPlay: 'playbin' element not found, please check your setup
^CTrace/breakpoint trap (core dumped)

I tried the following:

• uninstalling gstreamer (bad idea)
• reinstalling gstreamer using apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio
• reinstalling ubuntu desktop

I'm pretty much out of ideas as when I google the problem I only get obscure problems on github which don't seem to resemble the problem I have.

Can anyone tell me what may be wrong? I will gladly provide logs if you need them.

Thank you very much for reading. Have a good one.
