Brand new installation of Ubuntu 11.10 and then install the nvidia proprietary driver (280.13) by selecting "Additional Drivers" -> driver activated and used (according to the same menu). When I type "glxinfo" in a terminal I get this error:
X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 137 (NV-GLX) Minor opcode of failed request: 4 () Resource id in failed request: 0x5400003 Serial number of failed request: 32 Current serial number in output stream: 32
"lspci | grep VGA" gives:
02:00.0 VGA compatible controller: nVidia Corporation G86 [GeForce 8500 GT] (rev a1)
Before this upgrade I was on a 11.04 perfectly functional and fluids with 3D effects ... Also, I work with dual screen (configured with nvidia-settings) and when I select the menu "glx information" nvidia-settings crash ... I don't understand these errors because my environment was functional prior to "clean" installation...
Do you have any ideas ? People in the same situation? Thank you in advance for your help.
