I'm running Ubuntu 20.04 LTS on a ThinkPad P72 with a Quadro P5200. I recently purchased the ThinkPad Workstation Dock Gen2 and have been having issues with external displays on it.
There are a multitude of issues with this. Sometimes you can plug in displays and both will show up fine after running xrandr --auto. Sometimes only one will appear and the other will stay black.
There is a chance for any of these things to happen after making a display configuration change:
- Nothing (displays work fine)
- One display stays black
- All displays including laptop internal display freeze, which is recoverable only by physically disconnecting the displays from the dock
- Displays flicker on and off rapidly before every one goes dark including the laptop's internal display, requiring a hard reset.
I have tried:
- Upgrading to a newer kernel version (5.6.7) via mainline
- Upgrading all system firmware, including dock, to latest via Lenovo Vantage in Windows dual boot
- Downgrading the dock firmware from 3166 to 3164 - despite suggestions by people in this thread in the Lenovo community https://forums.lenovo.com/t5/Ubuntu/Thinkpad-P1-Gen2-amp-Thunderbolt-3-Workstation-Dock-amp-Linux-Ubuntu-Monitor-s-black/m-p/4575709?page=3 - this did not work
- Downgrading the NVIDIA driver version to both 435 and 390 - neither worked

Downgrading to an older kernel (4.19) appears to work, but it still has some issues with locking up while repositioning displays using xrandr.
