Just started using Ubuntu 16.04 and for the first while everything was great. I could switch between my two graphic cards no problem. But after a regular update the graphics are being reported as Gallium 0.4 on llvmpipe (LLVM 3.8, 256 bits)

I've tried following some answers on this site (for earlier versions of Ubuntu) about how to get rid of Gallium but to no avail.

Any help on this matter will be appreciated.

That would seem to indicate that you are now using the open source noveau drivers for your NVidia card. You need to go to the Additional Drivers tab under Software & Updates in System Settings, and select the proprietary NVidia drivers to use.

I had the same problem with XPS13 ON INTEL HD 620 graphic card.

I tried several options, the only thing which worked was to upgrade kernel to 4.9. now the system uses the hardware gpu instead of cpu. You also might see the cpu usage will drop.

Here is the link to upgrade to 4.9 kernel version http://ubuntuhandbook.org/index.php/2016/12/install-linux-kernel-4-9-ubuntu-linux-mint/

Having just spent several hours battling with the same problem, the solution (for me) was eventually straightforward. This was downloading the NVIDIA..384..run file directly from NVIDIA and installing it that way. Trying it through various package managers or apt-get was a dead-end. This was on an Alienware Area51 with a GTX1080Ti running Ubuntu 16.04 (with the problem caused by removing a 2nd 1080Ti card).
