I'm currently running Ubuntu 10.10 (64 bit), the GPU is an ATI Radeon HD 4290 onboard a ASUS M4A89GTD PRO/USB3 mainboard. The Ubuntu wiki doesn't cover 10.10 yet and I also don't know if that method would support direct rendering. I heard mentions of
xgl, what are the differences? Where should I start?
Will the HowTo: A well performing, full eye-candy, accelerated pseudo-multiseat setup on a single dualhead GPU. for Ubuntu 9.04 still work? I'm afraid it omits how to setup two input devices and sound however...
http://multiseatonlinux.blogspot.com/2010/06/part-1-setting-up-base.html covers 10.10 but requires pinning
gdm. Is that circumvenatable? Also how does that setup have to be modified for dual-head?
