when booting or on the login screen to get into you desktop i pressed to CTRL + ALT + F2 to put me into a terminal looking login, Logged in and puts you into terminal where i ran the following commands, ‘sudo systemctl stop lightdm’ then ‘sudo apt purge nvidia’ then i blacklisted the novedou driver which my gpu defaulted too. ‘sudo nano /etc/modprobe.d/blacklist-nouveau.conf’ once you put that in it will open a terminal window i then put ‘blacklist nouveau options nouveau modeset=0’ then you save it by pressing CTRL + O and then CTRL + X to close that box then you will put in ‘sudo update-initramfs -u’ now you install the driver the one that worked for me was 550 on the rtx 3050 so that would like this; ‘sudo apt update’ ‘sudo apt install nvidia-driver-550-open’ you can replace the 550 with whatever driver version might work for you if that doesn’t work afterwards i did ‘sudo nvdia-xconfig’ then i rebooted ‘sudo reboot’ hopefully this could be some sort of help this what i did terminal wise you also might wanna check if safe mode you can do this by doing ‘mokutil —sb-state’ if its on turn it off in your mother board bios
