Ati

From wikinotes

I haven't had great experiences with ATI cards in linux I'd advise against it if possible - especially on laptops that tend not to have their flagship cards.

Specifically, I've had issues with HDMI support, and fairly recent cards that no longer have driver support.

##### Agnes:
Unfortunately Radeon HD 2300 is a R500 generation card, and it's prerequisites are:
Kernel <=  2.6.29
Xorg   <=  1.5.3
pacman -S xf86-video-ati		# (Open Source Driver)
