I am unable to open the Settings on my installation of Ubuntu 18.04. There are multiple questions on the site already related to this, but the details of their situations seem different.
If I open Settings by searching the Settings application and clicking on it, its name appears on the top of my screen next to a spinning wheel for a few seconds before disappearing (similar to the situation in this question). If I run
gnome-control-center directly from the terminal, it hangs for a few seconds before exiting with a timeout message.
mees@mees-ThinkPad-L480:~$ gnome-control-center Failed to register: Timeout was reached
I can however get the version:
mees@mees-ThinkPad-L480:~$ gnome-control-center --version gnome-control-center 3.28.2
I have run
sudo apt remove --purge gnome-control-center sudo apt autoremove sudo apt install gnome-control-center
Some of the answers mention nvidia drivers, but I do not have an nvidia graphics card, so this should (?) not be the issue.
I was in the process of trying to update my Wacom drivers (following these instructions) when the problem occurred.
