No shutdown option in KDE with Compiz-Fusion

I have installed Compiz-Fusion on several Ubuntu machines,
all
different hardware, with KDE. In all of them, the option to
shutdown
or reset the computer is absent from the KDE logout buttons
when
running Compiz-Fusion. I have searched google and see that
others have
this problem, but I do not see a solution. Is there a known
solution
to this condition?

Thanks in advance.

I suspect this is because you are running under Xgl right?

KDE probably detects that it's not the only X server running
and assumes
that that could be another user and so does not give you the
option to
shutdown.

Just a rough idea... not confirmed.

I used to have that problem. If you are using Xgl, the
information
here might help:

h
ttp://ubuntuguide.org/wiki/Ubuntu:Feisty/GettingStarted#Inst
all_Beryl_using_proprietary_FGLRX_drivers_from_ATI

In short, to fix that problem with Xgl (on display :1),
something like
this should be run (probably before kde/gnome session
startup):
  cookie="$(xauth -i nextract - :0 | cut -d ' ' -f
9)"
  xauth -i add :1 . "$cookie"

Thanks. I added the lines to /usr/local/bin/startxgl which
now looks like this:
#!/bin/sh
Xgl -fullscreen :1 -ac -br -accel glx:pbuffer -accel
xv:pbuffer &
sleep 4
export DISPLAY=:1
cookie="$(xauth -i nextract - :0 | cut -d ' ' -f
9)"
xauth -i add :1 . "$cookie"
exec startkde

However, I still don't have the buttons. If it is because of
XGL, then
would I be better off running without XGL? I have the ATI
X1400 in
this laptop, and I have heard that the proprietary drivers
now support
Compiz-Fusion without XGL, but the performance is very bad.
Does
anyone know more about the issue?

Thanks.

Uhm, I don't know about your video card, but I just
installed the
latest ATI proprietary driver and adding these two lines to
my
xorg.conf seems good:

Option         "Textured2D" "on"
Option         "TexturedXrender" "on"

The performance under XGL are very poor, but using X they
are ok.
Thanks to Karthik Ramgopal for this hint!

Pierpaolo

Pierpaolo, when one uses XGL, is he not using X as well? I
thought
that _any_ graphical output in Linux required X (X.org or
X86). Is
this not so? In wikipedia it says that XGL is an X server
architecture. Does that mean that it replaces X.org and X86?
Is there
a page that explains it all in terms that someone with a CS
background
could understand? (us ME majors don't understand much  )

Thanks

 I have an ATI Mobility X300. Catalyst 8.3 + AIGLX gives
pretty good
 performance with Compiz. So you should remove Xgl and give
the latest
 catalyst a try. That would be the best solution to your
problem. And
 enabling Textured2D and TexturedXrender options doesn't
make any
 noticable difference here.

Thanks, Erkin, but specifically the X1400 is a known
problematic card.
And other than the shutdown buttons, I have no problems so
I'd rather
leave well enough alone.

I wasn't worrying about semantics, I was trying to educate
myself.
This is all very foreign territory for me. And Compiz has
been very
difficult for me to install. Were it just eye-candy I
wouldn't care,
but I am rather dependent upon the zoom and colour-invert
functions.

I just tested out Ubuntu 8.04 alpha6, and as that will be my
platform
in the near future, I will concentrate my efforts there. I
will
experiment with XGL and without XGL, and I will try with
both the free
driver and the proprietary driver. When I run into problems
that I
cannot solve, I will ask here I promise .

Thank you very much for the patience, and helping me learn
and solve problems.

Thank you Colin. That's exactly what I wanted to say.
