I installed a different nvidia driver using the update utility, when i rebooted the computer, it just shows a black screen
Welcome as a new member of the forum. Can I just ask you to edit your forum profile to indicate which edition of ZorinOS you have e.g. Pro, Core, Lite etc.
Please tell us which Nvidia card you have and which driver you installed?
What driver version did you install and what gpu do you have ? Try booting into recovery mode and undo the change.
Nvm, I fixed it by turning the pc on and off, sorry for wasting your time
You did not waste anyones time, we are here to help users. Even i post questions here because i am pretty new to linux.
