I have three monitors and Xinerama enabled. From what I've read Xserver-XGL is the only way to get compositing effects, i.e. compiz, going with Xinerama enabled. I like Xinerama since it's one big desktop, and I also like compiz. :) My goal is to get my cake... and eat it too. I grabbed the xserver-xgl package out of the hardy repos... installed it on my jaunty box. I can get it to launch as an overlay on display :1, but am having a horrible time getting it to properly launch with GDM. This is what I've done so far... if someone can point me in the right direction that would be fantastic. I have a script in /usr/bin/startxgl.sh, which contains <pre class="code">Xgl -fullscreen :0.0 -ac -accel glx:pbuffer -accel xv:fbo -br & sleep 1 export DISPLAY=:0.0 exec dbus-launch --exit-with-session gnome-session </pre> I then created /usr/share/xsessions/xgl.desktop which pointed towards the above script, selected that from GDM when I logged in. And... it's not working... I'll be honest I really have no idea what I'm doing. :) Although when I launch the Xgl command above while logged in, I launch it to display :1 of course - it works fine. Well, it launches as root and it appears as an overlay... not ideal but functional. If someone can point me in the proper direction, it would be much appreciated. Also, since I'm on the subject... Why was xserver-xgl dropped from ubuntu after hardy? It seems to be the only method of getting one big desktop (Xinerama) across multiple GPUs.  <pre class="code">Thanks for the time, Daniel </pre> </body> </html>
