Mageia 9 upgrade has broken graphics driver. SOLVED!

[petechristyuk]

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?

Yes, thanks! I just found that half-an-hour ago, before I saw your post, and have managed to sort it! But many thanks anyway!

I'm a bit puzzled as to why the update replaced a legacy driver with a mainline one, but there again, NVidia on Linux is generally a pain in the posterior. I use either AMD or Intel on all my own machines, having given up on NVidia ages ago. That's why I had an old NVidia card to put in my wife's machine. Perfectly adequate for her requirements, but oh! Those painful NVidia drivers....!

You're welcome. Glad you got it sorted!
