Bug ID: 70701 Summary: With DPM enabled, Radeon 4570 (R710) doesn't remain in Single_Disp state Product: Drivers Version: 2.5 Kernel Version: 3.13 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: abhinav.kumar.in@gmail.com Regression: No
When using DPM with the open-source radeon driver, the Card first gets into Power-State-1 which is the desirable one. But after few seconds, it changes its state to a seemingly multi-display one.
Tested on a Dell Studio 1555 with Radeon 4570 running Trusty alpha and openSUSE 13.1.
