External monitor requires unplug/plug every time I boot

Framework Laptop DIY Edition Linux

Hi all,

I’m having trouble getting my laptop to detect my external monitor on startup. Unplugging and replugging the hdmi cable fixes the problem every time, but I would like a more permanent solutions where I can leave my cable plugged in. I have tried multiple monitors, multiple cables, and multiple expansion slots and all have the same issue. I’m on Ubuntu 21.10. Thanks for your help.

I’ve actually had the same experience with my Thunderbolt 3 dock. For me it seems to be related to how long my laptop was turned off before I turn it on. However, unplugging and plugging it back in turns my dock on (at least the LED light turns on) and everything starts working properly.
