Hello, I have installed NVidia Geforce 460 with Ubuntu 11.04 machine and glxinfo correctly identifies that NVidia card is installed. But when I go to Administrator->Additional Drivers. I see that NVidia Accelerated Graphics Driver with green button on, but below I also see that "This driver is activated but not currently in use. I am confused with this message. Can someone explain what does this mean and what I should do ? Am I missing something ? Mir.
