It’s currently an old Nvidia card with whatever was automatically configured when the system was installed (nouveau?). I don’t know what the replacement card will be yet. I have a box of bits I need to dig around in. Whatever it is, it will be a few years old.
I need to replace this card because it’s playing up and getting worse.
I simply want to change the graphics card on a PC. How do I get X to reconfigure the driver? (I could do it in the old sax days.)
The X-server will largely take care of this automatically at boot (using open source drivers). For NVIDIA (or AMD hardware), you can then decide on wthether to install proprietary drivers.
