http://askubuntu.com – I have been developing something in webGl, and before the update I was able to run it on Firefox (Opera and Chrome fails, for some reason). After the update to latest Ubuntu version it has stopped working. In the same computer I have Vista installed and webGl works in Chrome, Firefox and Safari, so i guess that the Grapic card is ok. I have tried changin the driver (is an nVidia), but stil fails. Thanks in advance!! (HowTos)
