Screen fading out and in.
I have two DELL OPTIPLEX 330 x64 PCs with dual core (2.2ghz x2), 2gigs ram. First one is dual boot with Ubuntu on top of Windows XP pro 86. Second one is stand alone Ubuntu.

The CRT monitors on both PCs periodically fade as if they are going into standby mode. But they don't go completely black. This only last several seconds. I have disabled 'TURN OFF SCREEN WHEN INACTIVE', and this happens while I'm typing or moving the mouse. There are no screen savers installed. The first one doesn't do this when I log on to WinXP. The second PC seems to do it more often than the first. This happens with nothing other than a browser loaded.

Also, the second PC runs slow and there seems to be a lot of HDD activity. I don't know if these problems are related. I suspect this is due to pending hardware failure. I'm going to pull the HDD and ram out and put it in a third OPTIPLEX I have on hand and see what happens.

Anyone (WHO HAS EXPERIENCED THIS PROBLEM) have any idea what causes the screens to fade like this? In all my years I have never seen this type of anomaly

xcompmgr

xcompmgr(1)						      General Commands Manual						       xcompmgr(1)

NAME

       xcompmgr - sample X compositing manager

SYNOPSIS

       xcompmgr [-d display] [-r radius] [-o opacity] [-l left-offset] [-t top-offset] [-acCfFnsS]

DESCRIPTION

       xcompmgr is a sample compositing manager for X servers supporting the XFIXES, DAMAGE, and COMPOSITE extensions.	It enables basic eye-candy
       effects.

OPTIONS

       -d display
	      Specifies the display to manage.

       -r radius
	      Specifies the blur radius for client-side shadows.

       -o opacity
	      Specifies the opacity for client-side shadows.

       -l left-offset
	      Specifies the left offset for client-side shadows.

       -t top-offset
	      Specifies the top offset for client-side shadows.

       -I fade-in-step
	      Specifies the opacity change between steps while fading in.

       -O fade-out-step
	      Specifies the opacity change between steps while fading out.

       -D fade-delta
	      Specifies the time (in milliseconds) between steps in a fade.

       -a     Automatic server-side compositing.  This instructs the server to use the standard composition rules.  Useful for debugging.

       -c     Client-side compositing with soft shadows and translucency support.

       -f     When -c is specified, enables a smooth fade effect for transient windows like menus, and for all windows on hide and restore events.

       -n     Simple client-side compositing.

       -s     Server-side compositing with hard-edged shadows.

       -C     When -c is specified, attempts to avoid painting shadows on panels and docks.

       -F     When -f is specified, also enables the fade effect when windows change their opacity, as with transset(1).

       -S     Enables synchronous operation.  Useful for debugging.

BUGS

       Probably.  Please report any you find to http://bugs.freedesktop.org/.
