Thanks, Bog (is it okay if I shorten your name? )
I tried removing the conflicting packages, but everything went in tilt… got to the greeter but as soon as I entered my credentials, I got a black screen. Tried different kernels and all, but it just wouldn’t work.
Ok, I am just gonna brag in the next segment here, as I am still new but I managed to save my system and I am insanely proud of myself
At the grub menu I launched the system by going into tty and started removing the almost all the Nvidia packages I installed and reinstalled the old ones (440xx).
I rebooted, and got the (can’t recall the exact message) ‘Failed to start lightdm-greeter’. Rebooted to an older kernel and everything worked fine! No settings lost or anything
I still don’t know why all of this happened, though. I am using the latest (58) kernel and tried installing the 450 drivers that belong to said kernel…
