This question already has an answer here:
How do I tell GRUB to boot Ubuntu in command-line and not to load any AMD graphics drivers?
It seems that my laptop's Graphics card is broken - there are blue stripes. I am able to get to the GRUB menu with these blue stripes. However, once I chose "recovery mode" the screen just freezes and cursor keeps blinking forever. My goal is to somehow boot into system and copy all personal files to a remote host, but I can't do that presumably because Ubuntu tries to load AMD GPU driver and switches graphics mode. The same issue happens also If I try to boot my system with USB flash drive.
