BT5 cant succesfully detect screen resolutions - New install

[655321]

Just installed BT5 KDE 64 bit on my laptop (Lenovo T420s, intel i5, NO nvidia card). Everything is working great except for one thing, the max screen resolution I can get is 1024x768, which is not the max resolution supported by the card at all, also the animations sometimes are a little slow and I can see on ocassion the window redrawing (like when I pull yakuake terminal from top).

This leads me to think I dont have direct rendering activated but:

glxinfo | grep rendering
direct rendering: Yes

What can be the cause of this? how can I get the capabilities of this card working for backtrack?

PS: I have Arch Linux on this same laptop and works very well, so I am guessing its a misconfiguration or a missing package.

Thanks a lot for the help!
