PopOS 20.20 - external monitors (detected and working) via TB3 dock.

A TB3 developer explained that this problem is not related to TB3 as the DisplayPorts are made available via the docking station firmware.īelow is the /sys/kernel/debug/dri/0/i915_display_info for Devuan and PopOS. Initially I thought the problem was related to the thunderbolt 3 and asked the TB3 community for help.

Even though the USB ports on the dock functions as normal, for example a USB camera can be used via the dock.

In Devuan, Xrandr does not detect the externally attached monitors. Whilst the officially supported PopOS is able to detect and use the two external monitors without any problems.
