PS3 controller doesn't work with Retroarch

Hi all,

I’m new in this forum, i recently discovered Retroarch and I think it’s great. I hope someone can lend me a hand whith some problems I can’t solve.

One of those problems is I can’t make a PS3 bluetooth controller with retroarch.

My system is:

-Ubuntu x64 -Retroarch -QtSixA -PS3 bluetooth controller and usb dongle

I have the controller working on the system, in fact it works with games such as Super Tux Kart.

In Retroarch, if I go to Settings, Input Options, in “devices” I can select “PLAYSTATION®3 Controller”, the problem is that once I run a game it doesn’t work at all.

My question is: What else do I have to do to use the controller with retroarch??

Many thanks in advance
