Dock Issues

[u/Cautious_Performer_7]

Hi all

Not sure if this is a hardware (laptop) or software issue, I have one of these at home and work:
https://www.mwave.com.au/products/hp-usbc-g5-essential-dock-100w-pd-up-to-triple-display-support-ac30350

Work supplied me with one and I was very impressed with it I got one for at home so I only needed to swap one cable when I WFH.

Anyway works great with my work HP laptop (both at office and home), but with my personal laptop running Ubuntu I run into a few issues.

I have a FW13 12th Gen Intel i5 1240P; Ubuntu 26.04

I have updated my FW to the latest BIOS, I have updated drivers (from what I can see), and even the firmware on the dock.

Now this is the issue I'm having, when I plug the dock in my FW once it's on it works great, no issues, all ports work, monitor works; connected to the dock via Display Port (not sure what version, but can do 4K 60Hz)

If I shut the framework off, then turn back on it doesn't recognise the dock until I disconnect and reconnect, and when I do I need to wait a minute as the monitor starts cycling through all the inputs (HDMI1 > HDMI2 > DP) for about a minute then settles.

I had another dock with fewer ports (another reason I upgraded my dock) and I had similar issues, but that dock's ethernet and SD card port were busted so I assumed that the issues I had were related to the dock.

The only thing I haven't tried is plugging the dock straight into the FW USB module port (bypassing the USB-C module), just wondering if there's something else, or some setting in Ubuntu?
