Comment 24 for bug 1841826

Lenovo 4338 Mini-Dock with Nvidia K1000M running Dual external monitors. Ubuntu 20.04 suspends after login as mentioned. This seemed to start after loading the Nvidia 390 driver since the Nouveau driver did not work correctly. The video is fine now and everything works fine except I login, the suspend occurs, I press the dock power button and the machine runs normally.
My first assumption is its the video driver and I searched for suggested fixes or alternative drivers. Not sure which way to go seems like a few Lenovo users here are in the same place.
