I bought a new Dell 660s for learning Linux! It is Intel i3, 4 GB, 500Gb HD, 23" dell led display and a nVIDIA GT 620 video card. I chose Ubuntu 12.04 LTS amd64. It is freshly installed.

I added a PPA source (see and installed the package nvidia-current and then rebooted.

The video card works on 1024x768, instead of native 1920x1080. Only resolutions of 1024x768 and 800x600 can be chosen in the system settings. Even worse, when I Ctrl+Alt+F1 to F6, all the ttys are blank. In fact, I tryed many times and read many texts online. All I can do now is to try to ask here for help. enter image description here

Now desktop display resolution is better. And now, I press Ctrl+Alt+F1 to F6, the screen is not that blank but changed to a black screen with only a blinking prompt as '_'. The TTY is not working still. Dell 23"

To get the very latest Xorg and nvidia driver for Ubuntu 12.04, you should install the X-edgers PPA.

Please go to their page and read their disclaimer.

However, I do use this PPA in production on AMD and nVidia workstations and latops, and it's working well.

You should not put the instructions on how to add their PPA directly on on ask Ubuntu. X-Edgers asks clearly that you should point to their page, because they want to be sure that users read their disclaimers!!! – ttoine Mar 18 '13 at 17:36
