I've been working with Ubuntu 16 (and 14 before that) on my new Lenovo t460P for some time now. While it's possible to work the user experience is inferior to what you get working with Windows on the same machine.

The main problem is with the responsiveness of the display. It's evident mostly on the browsers on the machine (FF and chrome), but also the general feel of the machine is "off".

I suspect that the OS is not taking full advantage of of the display hardware which should be quite good on this machine.

I have zero experience in tweaking display in Linux... where do I start?

  1. How do I check the current display performance?
  2. How do I check if the display card is active?
  3. If not active - what do I do?

Adding the lshw -c video ouput:

  • Start by identifying hardware =) – Panther Oct 24 '17 at 15:58
  • Please enter the command `sudo lshw -class video` -> this should show some information about your display hardware, and what driver is being used. – Charles Green Oct 26 '17 at 02:05

  • You've got two graphics cards in your system - an NVidia card used for fast graphic response, and an integrated Intel card which does display graphics, but at a much lower speed/power consumption. Ubuntu has mechanisms for allowing you to switch on demand (`nvidia-prime`), and several people have written about how to install the nvidia drivers. Please see [https://askubuntu.com/questions/819322/fresh-installation-should-i-remove-nouveuau-before-install-nvidia-driver](https://askubuntu.com/questions/819322/fresh-installation-should-i-remove-nouveuau-before-install-nvidia-driver) – Charles Green Oct 26 '17 at 12:21
