In a forum about migraines and computer displays, i've found these instructions:"and try nomodeset for intel kernel module i915 and the fbdev video driver. It's basically the same thing as Standard VGA in Windows 7."

What does those mean ? how do i achieve them in ubuntu ?

    Those instructions seem like nonsense. You'll get a wrong resolution with nomodset, and an inferior driver with fbdev. How are they related to mirgraines is unclear. Search for those options if you want to know what they are. – mikewhatever Apr 21 '18 at 21:06
  • I haven't really dug deeply into the technical causes - i'm more interested in solutions. It's from a community of sufferers , who've noticed, both on windows and linux , that sometimes driver updates cause problems(. so they've tried using standard VGA drivers(on windows), and it helped. How do you get that on linux ? they say fbdev, nomodeset. – hulkingtickets Apr 22 '18 at 17:41
