User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.2a1pre) Gecko/20110325 Firefox/4.2a1pre Build Identifier: We are getting some troubles dealing with people that has acceleration enabled and a capable computer, like this: CPU: Phenom X2 de 3.1ghz RAM: 4gb Video chipset: GeForce 470GTX Drivers: 266.58 SO: Windows 7 64bits Ultimate We have another user with a 330M reporting "la pantalla en negro y unos instantes después se recuperara, con un mensaje de advertencia del display que decía "El controlador de pantalla nvlddmkm dejó de responder y se recuperó correctamente". --> "the screen went black and after a few moments it got restored, with a warning: "The video controller nvlddmkm stopped working and recovered successfully". For the 470GTX user, he disabled the acceleration in Firefox prefs and everything works now, the graphics section in about:support is as follows: Gráficos Descripción del adaptador NVIDIA GeForce GTX 470 ID del fabricante 10de ID del dispositivo 06cd RAM del adaptador 1280 Controladores del adaptador nvd3dumx,nvwgf2umx,nvwgf2umx nvd3dum,nvwgf2um,nvwgf2um Versión del controlador 8.17.12.6658 Fecha del controlador 1-7-2011 Direct2D activado false DirectWrite activado false (6.1.7601.17563, font cache 7.28 MB) Renderizador WebGL Google Inc. -- ANGLE -- OpenGL ES 2.0 (ANGLE 0.0.0.541) Ventanas aceleradas mediante GPU 0/1 Do you need more info about the users graphics? Reproducible: Always

This is indicative of a driver bug. We could consider blacklisting it, but I'm pretty sure we'll affect more people negatively than positively. They can send data about the driver crash to NVidia too.

We are having another issue with a frozen Firefox with a card: Gráficos Descripción del adaptador ATI Radeon HD 4300/4500 Series ID del fabricante 1002 ID del dispositivo 954f RAM del adaptador 512 Controladores del adaptador aticfx32 aticfx32 atiumdag atidxx32 atiumdva Versión del controlador 8.821.0.0 Fecha del controlador 1-26-2011 Direct2D activado true DirectWrite activado true (6.1.7600.16699, font cache 5,70 MB) Renderizador WebGL Google Inc. -- ANGLE -- OpenGL ES 2.0 (ANGLE 0.0.0.541) Ventanas aceleradas mediante GPU 1/1 Direct3D 10 Without hardware acceleration all things are running OK

Or does firefox remain frozen indefinitely. To be clear, if there's a black screen flicker and then firefox recovers along with the rest of the machine, it's just a driver bug and needs to be reported to ATI. If Firefox remains frozen there's most likely a bug in the driver, and a situation where Firefox should do a better job recovering.

In the last case, Firefox frozen for a few seconds and then started responding to user events, but without any black screen or any screen glitch. Anyway, ACK, I will ask those questions in the forums. Thanks!
