Description Anatoly Berbeka 2012-08-01 14:09:33 UTC
I apologize for my English.
I have incorrect picture. After installing Arch Linux or Opensuse 12.1 the picture seems like divided at 3 fragments, but instead [1 2 3] I have [3 1 2] or [2 3 1]. (Look the photo). No matter with which monitor - I tried 2 monitors. Sometimes I receive just black screen (1 of 3 cases, or [3 1 2] or [2 3 1]).
I have this problem at TTY and X too.

CPU: AMD Phenom II X4
GPU: AMD 6970
Xorg driver: xf86-video-ati 1:6.14.6-1
