Ultra Dock display out causes reboot when standby or reboot #66

Has anyone managed to solve the kernel panic reboots when connected to 40A2 Ultra Dock on a T440p?

The dock's USB, Audio, Display are all working. It's only when the laptop sleeps or reboots while connected to the dock's DVI/HDMI that causes the kernel panic reboot.

I'm having the exact same problem. Sadly don't have a solution either

Is there a display port connector? I don't have dock so I cannot test.

swatchie-1 commented 4 years ago

@jloisel Yes the dock has few display outputs: 2 units of Display port, 1 DVI, 1 HDMI. I'm trying out the opencore to see if it solves the problem.

Maybe display port works better.

@swatchie-1 how much monitors can you connect to the laptop and in what ports? i am thinking about getting a dock too.

MohrJonas commented 3 years ago

On the laptop the Mini Displayport works flawlessly. On the dock HDMI and Displayport work. They, however, cause a kernel panic when shutting down / rebooting / sleeping. So your best bet is to connect only one external monitor through the Mini Displayport. Maybe Daisy-chaining might be an option too. This however hasn't been tried yet.

@NastyGamer How much 1080p monitors can you connect concurrently? Doest it support 2k or 4k?
