This happens with the latest version in sid and, if I am not wrong, with the former version in sid as well.

I think you know (and hate :-)  ) me well, but let us remind just in case: my card is Intel and the composition is enabled with the option Option "AccelMethod" "EXA". KDE translucencies work OK.

When I launch compiz --replace, the screen goes totally white, and some seconds afterwards the mouse pointer appears.

If I Ctrl+Alt+F1 and kill compiz and gtk-windows-decoration, the windows of course have no border, but the keyboard does not work either.

Yes, the X server needs DRI drivers for AIGLX for Compiz.

No, that's not the case. What's probably happening is that
libgl1-mesa-dri is in the Recommends: fields, not in the Depends:
field.  And synaptics does not displays this clearly (Recommends: are
treated as Depends: in some cases).

xserver-xorg can't depend on libgl1-mesa-dri since it works without DRI,
but it's often better to have it installed. Same for Compiz, it can work
without libgl1-mesa-dri (if you have nvidia or fglrx) but it's better to
have it installed for most cases (other drivers). So we just need a
Recommends: libgl1-mesa-dri here.

I don't actually see Compiz recommending libgl1-mesa-dri here, but since
xserver-xorg must be installed before, there's no need to duplicated the
Recommends: from xserver-xorg into compiz. So I am closing this bug.

I don't use KDE so I will miss some details for some questions.

No. GLX_EXT_texture_from_pixmap is what enables the
distortion/rotation/... of windows. IIRC, the latter means that regular
windows can be distorted/rotated/... by Compiz with AIGLX. The former is
for window doing OpenGL rendering, which does not work with Compiz yet
(in the works for the next X server). Try glxgears in Compiz to see the
problem.

It may be conflicting with Compiz switcher.

You need the wobbly plugin. See http://bgoglin.livejournal.com/11253.html

Soon. Compiz Fusion packages are being uploaded these days.
