What happens if you uninstall xorg-x11-drv-intel?

The background here is that the intel driver hasn't had a release in
(checks) wow, over five years, which means its quality at any given
point is sort of unknown. You'd hope it would be converging on a good
state, and it does seem to have an ever-slowing change rate, but you
still end up with patches getting reverted after a month:

https://gitlab.freedesktop.org/xorg/driver/xf86-video-intel/-/commit/d90a2ff1a6f338fa70fc9a110d9f7b0e622c8a57


And this mostly doesn't matter because we default to a different driver
for most Intel hardware released since about 2006, with the notable
exception of your (Alexei's) machine which was new as of about 2010.

But the driver we default to on all the newer Intel chips should work
on yours too, though I'm not entirely sure whether you'll end up with
working 3D acceleration. And if you uninstall xorg-x11-drv-intel,
you'll fall back to the modesetting driver we use on the other Intel
chips, so, give it a shot?
