Well I chose v.2.6 because it said latest stable release 
Ill try with v2.8
Welcome to Linux! I’m glad that you chose Ubuntu.
It is a Colorgraphic Xentera GT… dxdiag tells me it has 4 ATI mobility radeon 9000’s (shaders aren’t supported on this card… but I’m sure it is the drivers, since it is a specialist card and Colorgraphic have stopped supporting it it’s hard to get updates)
With regards to that I’ll try it on my other computer it has a more standard card (NVIDIA 7600 GS).
