I just installed Ubuntu 16.10 and the screen is flickering as if a graphics driver update is needed, and some elements may not display, like chrome extensions such as Checker Plus for Gmail. but I am on the latest updates as far as I am aware. Are there any specific graphic updates for the macbook pro 11,5 that I should be looking for?

Thanks

EDIT: I have at least stabilized things for now by de-selecting the option pictured here

and setting the display resolution to 1920x1080 from previously 2880x1800.

EDT 2: Here is the output from lspci -k | grep -EA3 'VGA|3D|Display'

If I left out any other useful info please let me know, I am new to using Ubuntu.
