NVIDIA setting is not working after upgrade
after I have upgraded my ubuntu 10.10 to 11.04 I lost my taps menu ( application, places and sytem). I have reboot with the recovery mode which is working with low graphic and works fine. when i go to nvidia setting i get the message You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.
i don't know what to do?
please I need your help.
