Hello all.
I'm new to archlinux, and so far I love it. The only problem I have is a problem I already had before (on ubuntu), and is related with my AMD graphic card, a radeon hd 7870.
When I try to start X with the AMD open source drivers, I see strange artifacts on my screen, the display is completely fucked up and I can't do anything (not even swith to a tty to try a diagnostic).
I had the same problem with ubuntu : only the proprietary drivers allowed me to start X. But I'm not completely happy with catalyst so I wanted to go back to open source drivers and try to solve this.
Here's a picture of the problem:

The colored parts show my wallpapers, and the bits of archlinux wiki are the page I was before uninstalling catalyst to try the open source drivers. When I had this problem on ubuntu, I was even able to see parts of windows, because it was the last thing my card displayed I guess. Is this a cache thing ?
Anyway, I'm thinking it may be acompatibility issue with my card, but I can't find any information on that. Is there a way to check if my card is compatible with open source drivers ?
If the card is supposed to be compatible, what should I try next ?
Thanks in advance.

could you share kernel/X logs?
if 'dmesg|grep -i tahiti' is positive then look at https://bugs.freedesktop.org/show_bug.cgi?id=60879
