I was tinkering around to get wine to run better, and I managed to make my GUI disappear (I can still boot into Solus and acces the terminal with Ctrl+Alt+F2).
I tried reinstalling the nvidia-drivers, but it didn't change anything.
I really want to avoid reinstalling my OS.
The last command I typed into the terminal before this happened had something to do with glsl and grub, I'm trying to find the post from where I got it.
