I have in iMac a1419 with faulty NVIDIA GTX780 graphic card.
I have build a full Ubuntu system on Samsung 128 GB USB drive. I'm booting into the system by pressing on keyboard "alt" key and selecting the external USB based drive. Generally speaking all is working fine,but I need to boot via advance options to force the graphic save mode or I get glitches on the screen.
I wonder how can I set Ubuntu 22.04 to permanently switch off/ disable the NVIDIA graphic card, so I can boot system the normal way not via safe mode.
Thank you in advance for any help.
I have run the the below suggested command to purge NVIDIA driver and rebooted the system. Booting the system normal way was stopped halfway with the above information (please see the screenshot). Booting to graphic save mode allow me to load the system, but that means no change to the case. Thank you in advance for any suggestion.
Thank you in advance for any help.
sudo apt-get purge nvidia*
