Summary: DPMS doesn't work correctly
Product: DRI
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: minor
Priority: medium
Component: General
AssignedTo: dri-devel at lists.freedesktop.org
ReportedBy: nissarin at gmail.com

dmesg output
Monitor will keep constantly switching off/on when entering power saving mode:
- LCD going black
- OSD message "Entering power saving mode"
- LCD turns off, then immediately goes back on and the cycle repeats
This bug was previously reported on other list and should be fixed but
unfortunately it's still present on my system.
- Gentoo/AMD64
- kernel 3.1.0-rc6-00120 (linus + drm-fixes)
- xorg 1.11.0/1.10.4
- Radeon 6850 (+internal card disabled)
- Dell U2410
I'm not sure if this is relevant but the same effect can be observed on every
power mode, i.e. xset dpms force standby/suspend/off.
