When video goes into sleep mode, LVDS panel starts to show screens filled with b/w gradients and RGB colours in a cycle. In the same time a screen, connected via Display-Port goes into sleep mode correctly. This happens with and without X running. Ati drivers do not show such a behaviour.
Hardware: Acer Aspire 8942g with Mobility Radeon HD 5850.
Linux version 3.3 (but this happens starting with version 2.6.2x of 2.6.3x when I've tried KMS for the first time).
