Bug Description
I have a dual screen display (and I use the terms screen and display in accordance with X11 nomenclature). That is I have to monitors and their DISPLAYs are :0.0 and :0.1.
When I use the 3d eye-candy (i.e. Desktop Effects) I only get Xgl on :0.0 which is mapped to :1. As I understand it, Xgl does not support multiple screens. I have seen hacks around to start an Xgl on each screen (so that you end up with :1 on one monitor and :2 on the other). There are several issues with this:
1. Ubuntu gutsy does not seem to arrange for this to happen. It's Xsession startup thread of scripts seems to only address :0.0 and ignores :0.1.
2. But even given dual Xgls (:1 and :2), gnome will not work on multiple displays the same way it will work on multiple screens (i.e. separate and distinct taskbars for each screen).
This all makes dual-head setups quite limited with Desktop Effects.
Comments?
xserver-xgl has been deprecated upstream, and removed from Intrepid. Closing the bug as won't fix.
