Hi,
first of all, I hope it's correct to post my problem here, if it
belong's elsewhere, please let me know.
I'm trying to get compositing running with KDE 4.4.5 and an embedded ATI
gfx-card, free radeon driver on Debian stable/testing
# lspci |grep -i radeon
01:05.0 VGA compatible controller: ATI Technologies Inc RS880 [Radeon HD
4290]
It runs with KMS, I have hardware acceleration running (Xorg.0.log):
(II) RADEON(0): Sync: Separate Composite
compiled for 1.7.7, module version = 1.0.0
compiled for 1.7.7, module version = 2.5.0
(II) RADEON(0): [DRI2] Setup complete
(II) Composite (RENDER acceleration)
(II) RADEON(0): Acceleration enabled
But when I fire up system settings -> Desktop it says:
"Compositing is not supported on your system" under the first menu point
Desktop Effects.
I can use Cube-Switching as one can enable it under Multiple Desktop ->
Switching.
A guy from list xorg-driver-ati list pointed out:
"IIRC the KDE check for this doesn't always work correctly and can be
overridden. If that still doesn't help, you could try using the XRender
backend for compositing."
Any clues how to do this to enable compositing?
Cheers
Andre
