I started years ago using wmplayer on my ubuntu partition while having wm workstation set on the windows partition.
After updating to ubuntu 10.x i noticed the message that 3d acceleration was not enabled and since then I never was able to get it working.
No matter what the guest os is, never 3d acceleration runs in ubuntu, while it runs on windows host and used to work in ubuntu too. I have now updated ubuntu to 12.10 and still get no acceleration.
So far I have figured out the problem residing in some misrecognized or unrecognized video chip ( INTEL 945GM/GMS and INTEL 943/940GMLExpress Integrated Graphic Controller Rev.3) in Ubuntu, but despite I found and applied me\any different corrections I still don't get the thing running.
I added all possible ram and a fast ssd to my old notebook and it is still ways much faster than any new Lenovo thing of the same class, thus I will not give it up until it falls apart.
Yet I need to have it supporting 3d acceleration on Ubuntu.
I'll be happy to share any information (i.e. how to make an old X60 run faster than new boxes), test results, findings with who wants to help me out with this issue.
Ciao,
Pietro
