Funny enough, Fedora just works for me. The live CD convinced me enough to install and then it stopped recognizing the touchscreen and gyro components with my display.
Only after reinstalling on the fourth attempt did Fedora finally pick up my laptop display exactly like it did in the live USB.
I haven’t replaced a GPU on Linux, but my experience on windows has been to always uninstall and remove the graphics driver (forcing the Microsoft generic display driver) before replacing the GPU.
Then, it was just a matter of getting the drivers installed before I’m good to go. Granted, this was under Windows 10
