Since Ubuntu 18.04.2, my laptop (Aero 15x) doesn't detect my external monitors any more. 18.04 detected them just fine. I tried updating to the newest Ubuntu (18.10) but they still don't seem to be detected.

I installed the recommended nvidia 390 driver also tried driver 4xx without success. Do you have any idea how to fix this?
