GNU/Linux Mint 19 Intel i915 Driver Setup – Step-by-step Guide
Hi! The linked Tutorial shows you How to Install Intel i915 Graphics Driver in Mint 19.x Tara/Tessa/Tina/Tricia LTS GNU/Linux Desktop.
The drm/i915 Driver supports All (with the exception of some very early models) integrated GFX Chipsets with both Intel Graphics Display and rendering Blocks.
Especially relevant: the i915 Driver is already part of the Linux Kernel from the 3.13+ Release.
But, possibly you may experiment an Issue in loading it on Boot due to an Enabled GRUB nomodeset Setup.
In this case follow the linked instructions about How to Remove nomodeset Command from GRUB Configuration.
