I need to access the Appearance Editor in settings. This is missing in my Ubuntu 22.04.1 . So I found this webpage that recommends to set a variable:
No option for appearance in settings after upgrade to 22.04
This is:
XDG_CURRENT_DESKTOP=ubuntu:GNOME gnome-control-center
As soon as I set this variable in Terminal a settings window opens, but I do not find the Appearance Editor there. How can I get to the Appearance Editor? Does it still exist in Ubuntu Studio 22.04.1?
