So I accidentally stopped a running Xorg process on my ubuntu (with kill -STOP and the PID). I was trying to stop another process but got the wrong PID.
After I did it, immediately mouse and keyboard stopped working. On reboot, I can log in just fine (mouse an keyboard work perfectly, same goes for my windows setup and also ubuntu in recovery mode), but then the second I'm logged in I can't use mouse or keyboard again (neither usb nor the ones my laptop has). The mouse is just frozen. This means I can't open a command window etc. either. Other stuff seems to be working normally (time updates in the UI and I get notifications like HPLIP errors).
How can I fix this?
I'm on Ubuntu 18.04.
