I have the same problem since one day. I'm using Ubuntu 14.04.01 64bit, Kernel version 3.13.0-44-generic ,Lenovo thinkpad laptop t440p, Nvidia GeForce 730m.
A bit of history: After installing the system I immediately installed nvidia drivers 331, I had to immediately update them because I had some issues with unity desktop (login working, desktop present, but no interface, meaning no menu no unity dash). I updated to version 340.58 and everything was working after disabling nomodeset as a grub option. Able to switch between intel and nvidia with prime-select command and within nvidia-settings interface. The suspension was working good with nvidia loaded, not with intel, for some reason the login page after the suspension wasn't able to recognize me as a user... One day ago I did some system updates, don't know exactly which one, but I knwo it updated to version 14.04.0. I checked the version of nvidia drivers, they were the same 340.65. I suspended my laptop as I always did during the last weeks and it wasn't able to restore the system. It shows black screen, no login window, no external monitor recognized. I am able to switch to another workspace, sun prime-select intel, and reboot. The I have everything working again (but the suspension..), as soon as I change again to Nvidia, I get again the black screen, i can hear the sound of the login page, nothing more. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331 in Ubuntu. https://bugs.launchpad.net/bugs/1362848 Title: ubuntu 14.04 after install nvidia binary driver 331.89 black screen and freeze Status in nvidia-graphics-drivers-331 package in Ubuntu: Confirmed Bug description: I'm using Ubuntu 14.04 64bit, after install nvidia binary driver 331.89 from Additional Drivers application then reboot, it shows black screen, no login window, I even can't use ctrl+alt+F2 to switch to text mode, then I reboot and go to recovery mode, use 'prime-select intel' to switch to intel GPU and reboot, everything is fine, but as soon as I switch to nvidia GPU, still same issue.
