I run into a couple of issues getting started with the Oculus SDK v0.2.3 on Ubuntu 13.04 using a Radeon HD 7950. I created a quick start guide for Ubuntu 13.04 that details the steps required to get the SDK working:
The part that details how to configure the virtual screens in Ubuntu 13.04 requires the Catalyst Control Center and is therefor applicable to AMD GPUs only, but similar instructions will likely work on other hardware as well.
Just sharing some random Linux experience.... may be helpful to somebody....
Ubuntu 13.04 and 13.10 experience (with DK1 obviously) :- -- works (apparently) flawlessly with Xfce (and XUbuntu). -- under the standard Unity desktop the actual framerate of Tuscany demo is somehow adversely affected (reduced) on my machine! (seems jittery and not smooth). -- works (apparently) flawlessly with Kubuntu (KDE Plasma desktop).
I found that running KUbuntu KDE (i.e. just the current standard "KDE Plasma desktop") is much nicer than MS Windows in fact. Right clicking on window titles you even have a very useful Move-Window-to-Screen option. So in general I was happy that things worked well enough under KDE that I could use Rift under Linux effectively. Generally Window's multi-screen usability for Rift was very crappy IMHO. (Not knocking Windows specifically, but just saying.)
I am trying to get the Rift to work under CentOS 6 with three screens (the third being the Rift), and everything works except no head-tracking is happening. I will gather more debug info and then probably create separate issue post about it.
