Nvidia/intel HD Graphics display + Nvidia COMPUTE

It's been a long time today. Intel integrated graphics display. Finally it was all done, and here's a record.

 1. The first thing in the BIOS is to open Intel HD graphics. I set it up as the main video card, and the monitor is also connected to the port of the core graphics card. After restarting, I card warning low resolution, into the desktop  2. The command to switch the n/i card is prime-select (the installation package is Nvidia-prime, does not need to install the legendary Bumblee, etc.) originally this command also has, but reported the following error:  sudo Prime-select Nvidiaerror:alternatives is not set up Properlyerror:nvidia mode can ' t be enabled sudo prime-select QUERYUNKNOWN&N BSP, it is estimated that the graphics card driver is the problem, think about updating it.  3. Because I originally installed the drive is 346.59, into the source to see what can be updated, see the following three things NVIDIA-346-UPDATESNVIDIA-346-UPDATES-DEVNVIDIA-346-UPDATES-UVM no matter 3,721 , all loaded, the driver upgraded to the 346.89 4. installed, it is possible to enter the system, by default Prime-select query out of NVIDIA, this time call Nvidia-smi, found that x, Compiz memory is n card provided, so with sudo prime-select Intel switches to I card, log out.    can also install a Prime-indicator plugin, which will display a button to switch the graphics card in the taskbar.  5. After switching to I card, there is a problem, the execution of Nvidia-smi error said to find Libnvidia-ml.solocate a bit, found that there is, but the version seems to be. 346.59, not very right.   Toss for a long time, finally found this library in/usr/lib/nvidia-346-updates/inside, so the library path to join Ld_library_path, then execute NVIDIA-SMI there is no problem, and can see the video memory is not occupied Happy!
