DisplayPort problems

[Others call me jean]

Hi community

Yesterday I installed Qubes OS and it works fine. Thank you guys!

But I could not solve one problem yet. Here my configuration:

- Lenovo T460s, NVMe SSD, i7-6600U
- Qubes OS 3.2
- 4.8.12-12.pvops.qubes.x86_64
- ThinkPad Ultra Dock (Docking Station)
- 2x Dell U2415b with DP to Docking Station

Before I installed Qubes, I used Arch Linux with GNOME. The Displays
normally works, even when I dock/undock from my docking station.

Now, the Qubes OS freeze/crash, when I plug in the display direct or
dock/undock from the docking station with DisplayPort. This is really
annoying!

With HDMI this problem does not exist. But unfortunately I have only 1
HDMI connection on my docking station (I don't know why, because with
daisy chaining you could use multiple display with only 1 DP port!).

Do you know a possible solution for DisplayPort support?

Thanks!

Did you ever get the DisplayPort to work? I have a Lenove thinkpad with displayport and Qubes doesn't recognise it by the look of things..

thanks :-)
