I have Gnome Shell Extension Manager installed. When I install an extension, such as ArcMenu, I am unable to activate it due to the slider being grayed out.
Things I have tried:
- restarting computer
- uninstalling and reinstalling Gnome Tweaks, Extension Manager
- activating extensions through the terminal
- all steps suggested at this Ask Ubuntu, including removing any existing user extensions from ~/.local/share/gnome-shell/, removing "ding@rastersoft.com" from extensions folder.
- using other extensions, including "Apps Menu"
I appreciate any assistance.
