>>2438novideo is fine too if you have a GTX780ti or older (so kepler and anything before that)
or if you have an ATI GPU from 2004-ish, they work too.
alternatively, you can get a Radeon RX 470/480/570/570X/580/580X and use ATI drivers (just cope with shit performance, no sleep/suspend/wakeup, and no gpu brightness-control), or cope with not having 3d support.
i havent tested AMD GPUs but if anyone can confirm that 3d werks without firmware, please let me know.
im a freetard on suicide watch using my thinkpad on a dock as a desktop because i can't find a proper GPU that isnt a GTX780ti.
