I'm kind of freaked out right now. Hopefully I can find a solution here. Something really strange happened.
Basically, all of a sudden, everything started to look messed up. The gui applications remind me of the classic theme in windows. All kinds of effects are gone. The gnome terminal has a black font on its black background. A custom profile I have in it has messed up colors too (it's black on white, it's supposed to be white on black).
I've seen similar questions on the internet, but the proposed solutions have been unsatisfying. I've tried various things:
- Changing the theme to something else and then back
- Clearing my cinnamon & gnome settings
- Creating a new user
- Installing official drivers for my video card (I hadn't done that yet)
... but all to no avail.
Here are some screenshots:
