screen 'flicker'/artifacts after boot into arch

i experience some sort of flickering/artifacts (dunno how to call it, it's like pixels flying across the screen) after i boot into arch. even when i'm (still) in a tty with no x session running. (before booting into arch, while in the grub menu, it's ok)

it looks pretty much like this.

my gpu is an ati radeon hd4570, i have the free radeon driver (xf86-video-ati) installed.
not sure whether it can be a driver issue though, because it happens even when i'm not in a graphical session?

unfortunately i don't know what to do or what to look at to fix this. investigating this issue i'm led to believe it could have something to do with grub or kernel settings or sth, but i have 0 experience with configuring either.

i'm dualbooting with ubuntu 14.04 btw, which also runs the radeon driver, and i don't have the problem there.

i'd appreciate any sort of help!

(this is my first time posting here, i apologize if i ignored any forum etiquette)

For Radeon you should use xf86-video-ati, not xf86-video-intel.

Hey, any luck with this? I've had this issue for months now. It's stopping me from using Arch on 1 laptop altogether and I don't have time to debug it properly.

nope. i believe it's because of the newer kernel (compared to ubuntu, where i don't have this problem). dunno how to tweak around to maybe fix it, maybe i'll just try to install an older kernel.

Re: screen 'flicker'/artifacts after boot into arch

i saw that, tried and it didn't change anything. like i said, the artifacts are there even in a tty, and without x-server or graphics driver installed. so it probably is nothing with x or radeon.
