Comment 23 for bug 1166765

Same bug here. Have a Dell Studio 1555, 64-bit, with Nvidia. Unity was working on Ubuntu 12.x, but after upgrading, no more unity. I've tried resetting unity, reinstalling, upgrading my distro, forcing OpenGL to work (doesn't start). I've tried with and without Nvidia's proprietary drivers (even forced beta drivers), to no avail. I've also tried many proposed solutions on the ubuntu forum. I've tried different xorg.conf too. Now I'm considering reverting to a Commodore 64 and emulating linux from the terminal, and live happy ever after ;-) Just kidding. Hope you find a solution.
