Bug #: 42034
Summary: rendering stops when screen blanked
Classification: Unclassified
Product: xorg
Version: 7.6 (2010.12)
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon

This is likely caused by vsync syncing.
Apparently vsync is generated when screen is blanked.
When running glxgears and screen is blanked (xset dpms force off) sometimes
glxgears would run at top speed, sometimes it would report 0 frames for the
period when screen is blanked.
Linux 3.0.0-10-generic
X.Org X Server 1.10.4
radeon 6.14.99
