Try using the nvidia-settings -> X Server Display Configuration -> Detect displays. I've successfully used it to display the desktop on two monitors (one @2550x1440, the other @1920x1080).

I am sorry but you are out of luck. Displaying 2560x1440 pixels requires using a higher graphics chip frequency and even if this is within the spec of the chip the laptop manufacturers disable anything above 1920x1080 to prevent overheating. I am yet to see a laptop whose spec says Support of external monitor @2560x1440 pixels . You can use your shiny ...

The NVIDIA drivers in my PPA are pretty much the same as the ones in the Xorg Crack Pushers PPA, but sometimes other stuff from that PPA can cause stability problems.

OK, I found a way to install and use newest Nvidia 346 drivers with Nvidia Prime. It seems that the problem is not caused by driver. Something else in the xorg-edgers ppa causes this problem but I don't know what it is. Caution: I'm no expert, I'm just trying things out. I don't know if this will mess my system up in future. Try this if you know what you ...

The standard Ubuntu NVidia drivers generate some problems on slightly older and slightly newer NVidia hardware. If you want more then the standard Ubuntu repository drivers, install the xorg.edgers PPA. As the xorg.edgers group ask not to give installation instructions directly without linking to their page, this is the best I can do for now... If you ...

Not sure if your question is only for nvidia hardware, but I have an Intel Nuc (which containts basically laptop hardware) with the Intel HD 5000 GPU that has a mini display port, and this works perfectly using ubuntu 14.04.
