Hello,
I've made a small change in the InitGLXP function and could get glxp
rendering to stop crashing gazebo. It still has some rendering problems
(specially when checking the frustrum option) but at least hw
acceleration is working.
My computer has a ATI Radeon xpress 200M ghaphic card with the ati-fglrx
driver installed.
Bests,
Pedro
