I have a Lenovo Z50-70 laptop, which has Intel Integrated Graphics and an Nvidia Geforce 820M; however, since I installed Ubuntu 16.04, it has not been using the graphics card. I have tried uninstalling everything Nvidia-related and reinstalling
nvidia-375, which then declares that it depends on
libc6-i386, which then returns
The following packages have unmet dependencies. libc6-i386 : Depends: libc6 (= 2.23-0ubuntu3) but 2.23-0ubuntu5 is to be installed E: Unable to correct problems, you have held broken packages.
When I try to install
libc6, I get
libc6 is already the newest version (2.23-0ubuntu5).
How do I install these, or is there another way to make my graphics card work?
In terms of other commands:
lspci -vnn | grep 3D -A 12 returns:
