EDIT: I kinda forgot to actually mention my problem. When booting nornall, I get stuck at a lonely white blinking cursor on a black screen, so startx seems to make some problems. I enter a TTY and run startx and this is what I get when running startx:
output of startx
What was the output ? It is not visible for me here.
Were you using startx successfully before ?
Or are you reverting to trying startx and you did use some graphical display manager like gdm, sddm or lightdm before ?
Could it be a disk space problem ? If you run out of space trouble can happen with various applications.
Can you boot from a previous kernel (At the GRUB or systemd boot menu) and see what happens ?
