F.A.Q : Frequently Asked Questions

Q : does Xgl works with Xorg 7.0 ?
A : Working on Xorg 7.0
Install "xserver-xorg-dev"
setup nvidia drivers
run script
-Then trying to start Xgl gives an error: cannot find default font 'fixed'.
-Try install libfontenc-dev and libfontenc1 else you can be resolved changing in the script the line reffered to xgl to:
Xgl :0 -fp /usr/share/fonts/X11/misc -fullscreen -ac -accel glx:pbuffer -accel xv:fbo:0
-If you get errors in gnome-window-decorator (not visualizing borders) downgrade compiz and xgl packages, as described in FAQ.

Q : I get "cannot open default font 'fixed'." when i launch Xgl
A : you need configure your /etc/gdm/gdm.conf to launch Xgl.
