XGL Setup Issue?

[Dachnaz]

I have followed the Gentoo wiki on setting up XGL. Under the Windowed Mode subsection of the Running XGL section, I (an nVidia user) run:

# Xgl :1 -ac -accel glx:pbuffer -accel xv -fp /usr/share/fonts/misc,/usr/share/fonts/other_fonts

And the standard grey nested X window pops up. Upon following the next step (being a compiz user), I run:

# LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ \
# DISPLAY=:1 compiz gconf

This causes my nested window to turn black, freeze and quit rendering. I can just click the X of my window manager, or ctrl+c in the terminal I created it with, to stop it. In fact, I can ctrl+c in the terminal I called compiz with, and it reverts to a grey screen. Nonetheless, it's not getting me anywhere. I am stuck here in the setup process. Any ideas? TIA.

It may be just related to xnest, that step is just for testing so you can skip it. It may work ...

when I write "compiz start" it shows me this:

compiz. real: Screen 0 on display ":0.0" alredy has a window manager; try using --replace option to replace the current window manager. compiz real: No manageable screens found on display :0.0

If I write

"compiz --replace gconf &"

This causes my current window freeze. I can't click the X of my window, because that tab disappears, and I can't change the current window. The only thig I can do is to restart my computer by clicking ctrl+alt+backspace... please help
BTW, I have nVidia GForce 5200 FX
