Hi, your R50p according to Thinkwiki has the same ATI FireGL T2 Mobility graphics chip as my T42p.
The inability to do 3D , or even reasonable 2D, is down to lack of support in the ATI catalyst driver, so that you have to use the "r300/r400/r500 based FireGL" or Xorg "ATI" drivers.
The internal BT is also a problem, until relatively recently (prior to Blueman) it wasn't recognised automatically, and I had to plug in a USB BT adapter.
The internal BT would then be recognised OK until the next boot.
At one stage Blueman, and subsequently BlueDevil, seemed to recognise the internal adapter without any help, but a recent update to BlueDevil reverted back to the original problem.
I now have Blueman installed again and the internal adapter is recognised by Blueman OK.
See this thread for my previous BT experiences;
