Tuxedo Pulse 15 Gen2 + USB-C dock - no network + external monitor won't wake after sleep

I have the Tuxedo Pulse 15 - Gen2 connected to a Tuxedo Triple Dock Lite [1] (i-tec USB-C/Thunderbolt Triple Display Docking Station).

An external monitor is connected to the dock and also a network cable for wired network.

My box is a Manjaro Linux, KDE, up to date with Kernel 6.6.5 - LTS kernel.

The problem I have is that if the computer goes to sleep, after waking up, the monitor is not available, the system doesn’t detect it. Also I have no network - ip doesn’t list the network adapter. I have to power cycle the docking station in order to re-detect the devices.

Does anyone know a fix for this? e.g. Firmware update for dock, some BIOS setting etc. ?

With Kernel 6.5 it was working - but Kernel 6.5 is marked EOL.

The Tuxedo Pulse 15 Gen2 has an AMD card, I don’t see the connection with the instructions provided in the link above.

This may be caused by the USB port being power down.

Some system ports may not be detected after a waking up. They may need a unplug/plug to be recognised.

You can check states manually as described in the man page
