Hi

i'm connecting an external monitor to my laptop running Ubuntu 21.10 using an HP Travel dock. Since yesterday the laptop doesn't detect the external monitor anymore. it was working perfectly fine until two days ago and I haven't changed anything since then.

The laptop has only Intel integrated graphics.

I've tried all sorts of things like using a different HDMI cable, plugging/unplugging both ends of the HDMI cable several times, etc.

The dock and external display work fine when using another HP X360 laptop with Windows 10, the problem only occurs on Ubuntu.

Any tips to solve this would be much appreciated since it's really bothering me not being able to use an external display.

My neofetch info, in case it helps is as follows:
