Hi! For completeness: I got the problem by update from 8.10 to 9.04. The screen became black for less than a second, randomly. No relation to graphics or cpu load identifiable.
System: Intel 32bit CPU: Intel(R) Pentium(R) 4 CPU 3.20GHz stepping 01 Card: ATI Sapphire X1550, 256MB Monitor: NEC Multisync LCD2690WUXi with resolution 1920x1200 at 60Hz connected via DVI lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] 01:00.1 Display controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] (Secondary) Since installation of package xserver-video-radeonhd and restart of the machine everything is fine, but it seems to be slower (in showing videos).
