           Summary: LCD display flickers (shuts down and immediately up) on
                    dual-head radeon.
           Product: xorg
           Version: 6.8.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: fax at 012.net.il


I'm using KDE as a desktop environment. Starting from Xorg 6.8.2rc1 I'm
experiencing the following problem: on some display updates, my primary display
(LCD, Apple Cinema 20"; I'm using Xinerama and radeon driver) shuts down and
after a moment it goes up again. This annoys me much and also I beleive it is
not health at all for my monitor. There was no such problem in Xorg 6.8.1.

Logs does not show any problems (dmesg too).

My configuration:
Linux kernel 2.6.{10,11}-smp (self-compiled)
Distribution: SuSE.
Video Card: Radeon 9200 VIVO.
MoBo: Tyan Thunder K7, dual Athlon MP 2200+
Memory: 1Gb

Here is my xorg.conf file:
