I had to reinstall X-server (I couldn't find another way to make X use the new Intel drivers for some reason). Except that, all is fine. Upgrade to kernel 6.2+, update Intel drivers, reinstall X, swap cards. I also had to modify my grub and my Xconfig a lot to make my old Nvidia card work, and cleaning it up took an hour. Overall, better experience than with Nvidia. If your computer/install is recent maybe you won't need to reinstall X at all. I kept my Linux across 2 mobo and 4 CPU over 10 years, I usually prefer patching/fixing the issues rather than reinstalling but I think I ought to clean it up.
