When I run the alpha demo from the gtk "tests" folder it says: "Screen supports alpha" and "composited"
But when I run the "composited window" demo I get the warning:
Gdk-WARNING **: gdk_window_set_composited called but compositing is not supported
I'm running Ubuntu Natty "not classic or classic-no-effects."
ATI Radeon HD 3200 (proprietary drivers.)
Compiz version 1:0.9.4+bzr20110415-0ubuntu2.
My graphics are listed here: https://help.ubuntu.com/community/RadeonDriver
And it says:
"Accelerated 3D support"
"All these Radeon(HD) cards and derivatives have good 3D acceleration support"
Log file here /var/log/Xorg.0.log
Contains the lines:
[ 36.557] (II) Initializing built-in extension COMPOSITE
[ 35.940] (II) fglrx(0): Enable composite support successfully
In the compiz settings manager I have composite checked.
In gconf-editor under: apps->metacity->general I have "compositing_manager" checked.
Why isn't this working?
