Hi All,

I've installed Ubuntu 9.04 on my Acer Aspire 5633WMLI laptop and Visual
Effects (set to 'Extra') and compiz effects (like the desktop cube and
rotation) all worked great. After connecting a external monitor however,
the Visual Effects is now set to 'None', compiz effects don't work
anymore and I cannot enable these anymore. When I try enabling the
Visual effects I get a pop-up with the notion "Desktop effects could not
be enabled". Disconnecting the monitor and restarting the laptop doesn't
make a difference: all effects are disabled and stay that way. Working
without the effects makes gnome much less user friendly, scrolling
through (web)pages is now quite a shocky experience, not great to work
with.

When the external monitor is connected, xorg.conf looks like this:

[CODE]Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
	SubSection "Display"
		Virtual	2560 1024
	EndSubSection
EndSection

Section "Device"
	Identifier	"Configured Video Device"
EndSection
[/CODE]

Since the effects do work fine with one monitor, I don't think this is a
hardware limitation, but correct me if I'm wrong :).

So my question is: how to re-enable the desktop effects, preferably also
when the external monitor is connected. If you need me to provide more
information, please ask.
