Bug #: 47708 Summary: LVDS panel does not turns off in stand-by mode Classification: Unclassified Product: DRI Version: unspecified Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: eugene.shalygin@gmail.com

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).
