I just did it today and it broke the display drivers. Had to redownload and
reinstall my drivers from the AUR again Even the X server wasn't working
and I had to go back to my Win7 because I forgot the AUR address
In the beginning of my installation I tried nvidia. It didn't work. I then
installed Nouveau, which didn't work very well either. I also had an
lts kernel, headers and firmware as a backup and for some strange
reason it was using the lts... I guess the normal kernel crashed.
I would try a different install with Nouveau and lts from the beginning,
but right now it would take some time. I have to figure out what needs
to be installed to make H&D2 work with Nouveau... something lib32.
