I have lenovo ThinkPad W520 with ubuntu 18.04 nvidia GF108GLM quadro 1000M.
I using x.org X server – Nouveau display driver, because only it works for me.
After every update I have problem with my external monitor - he wont turn on. I need to go to Software & Setting and to check/applay changes to activate nvidia-driver-390 and to back to Nouveau display driver and than reboot the system.
But from today that approach wont work as well.
Is there some solution for this problem.
