I've install Arch on my lenove z475 with AMD Radeon HD 6470M and HD 6520G, and I'v install xf86-video-ati, xorg, gnome3 But if I don't add "radeon.modeset=0", the screen goes black. If I add it, then gnome 3 default to "fallback" mode and screen resolution is poor. So... anybody can help to get the xf86-video-ati driver work normally?

PS: I've tried the "catalyst" but the topbar disappeared and it crashed twice, so I'd like to stick to xf86-video-ati now.

ati is not a real driver. It picks one of the other real drivers depending on what card it detects. – Ignacio Vazquez-Abrams Oct 7 '11 at 1:02

You need to use the catalyst driver for newer cards like yours, particularly if you want the 3D effects required for Gnome-shell... "All cards from HD 5xxx (R800) and newer are supported, but for now, with 2D support only." – jasonwryan Oct 7 '11 at 1:10
@jasonwryan So... using catalyst would be the only way? Are there any other drivers that I could try? "catalyst" won't display topbar... – wing67 Oct 7 '11 at 1:27
There are quite a number of options when using catalyst: you should work through this page: wiki.archlinux.org/index.php/ATI_Catalyst – jasonwryan Oct 7 '11 at 1:43
@jasonwryan I've tried "catalyst-generator" following that page... but still, could get it right... – wing67 Oct 7 '11 at 1:48
