I have exactly the same problem with an Acer 5755G laptop: Ubuntu 11.10 x64, nVidia Geforce 540M, integrated IntelĀ® HD Graphics 3000, nvidia- current 280.13-0ubuntu6.
After running nvidia-xconfig X won't start anymore. In my Xorg.0.log I also get: (EE) No devices detected. Fatal server error: no screens found Bug #660596 looks similar. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/643895 Title: nvidia propietary driver fails to load X with geforce 310M To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/643895/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
