Hi,

When I login from remote via VNC, NX or XDMCP to a KDE session the KDE
"Composite Manager" complains that it cannot find the "Composite
extension" and crashes. The setting is configured in xorg.conf and in
a normal session the "Composite Manager" does not complain.

Why cannot KDE find this setting when it's accessed remotely?!

As none of the remote logins you use support composite, it works only if you
login locally. I suggest you disable features that requires composite in your
KDE settings.

Aaah, okay, makes sense - although the actual error message is quite
misleading. It says that it cannot find the composite extension (isn't
that part of Xorg?) and that it needs Xorg 6.8 and the appropriate
entry in xorg.conf (which is both true for my PC).

Hm, that is a possibility. But I'd rather just disable it for remote
session - unfortunately there's no option for that.

Yes, it's a quite misleading error message, but still quite right, features
that can't be used over network like opengl will be lost for the session and
be a thing "not found".

No, sadly not.
One thing you could experiment with would be to have two configuration
directories, for example ~/.kde3.5 and ~/.kde3.5remote, and see to symlink
~/.kde to the right one depending on the connection (this will require some
tweaking on the kde scripts).

Another option would be using XiG instead of Xorg, that way you would get all
the needed features (but not sure if XiG has composite module or not) over the
network too.
