yesterday I was using my computer for studying watching video tutorials, and finished at just before midnight.
today I am home from work and want to continue the above and I turn on my computer and notice that all my theming has disappeared.
All my panels and window borders and applications like file manager thunar all have this classic light grey xp block style look.
What happened, ( I feel like it was a system update since I haven’t installed anything in a long time except keeping the system up to date daily). and how do I get my computer to look like it did?
