Same problems were in Ubuntu 13.04. Installing x-swat ppa (in 12.04 and 13.04) did not help.
Tried using following commands: sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install bumblebee bumblebee-nvidia sudo usermod -a -G bumblebee $USER But after that STAEM still can not start: Running Steam on ubuntu 12.04 64-bit STEAM_RUNTIME is enabled automatically Error: You are missing the following 32-bit libraries, and Steam may not run: libGL.so.1 Installing breakpad exception handler for appid(steam)/version(1370553818_client) Installing breakpad exception handler for appid(steam)/version(1370553818_client) [2013-06-23 14:18:25] Startup - updater built Jun 6 2013 13:48:29 -- 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/1193795 Title: Driver for Geforce gt 650m is detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1193795/+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
