Yesterday, my wife's computer brought up a notification that Mageia 9 was now available, and did she want to upgrade? I answered "yes" for her. The update seemed to go fine, informed me that it had successfully completed and that I should reboot.
On rebooting, the computer refused to bring up any form of GUI. I was left with a black screen and a flashing cursor.
I've managed to get it into rescue mode and the issue is the graphic driver. Mageia 9 automatically upgraded the NVidia graphics driver to version 535.xxx. This is incompatible with the GT710 card fitted, which requires a legacy driver, 470.xxx.
I can get to a command prompt, but nothing else. How do I remove the 535 driver and replace it with the 470 driver from the command line? Or even use the nouveau driver just to get it up and running again while I sort it out?
