When I click on the system settings icon in my menu, I get the bouncing symbol for a few seconds, but no setting manager comes up. I tried garuda-update, but that did not fix the problem.
I also tried right clicking the desktop and choosing display settings, which also failed.
I fixed it by reinstalling Garuda. My keyboard was set to British English and I was trying to change the locale. Since the install was brand new, it was no big deal to redo it.
I had changed various settings with no success. Rebooted numerous times. Banged my head on the table a few times too.
