I just rebased to f34 today, and my external display, which was plugged into the usb-c dock for my Lenovo t14s via displayport, wasn’t turning on. In my display settings, the external monitor is recognized, it seems like it should work, but it doesn’t. I swapped to hdmi and had the same issue.
I was able to use my second monitor by plugging an hdmi cable directly into my laptop. The nic in my dock is working, and my usb webcam plugged into the dock is also working.
Has anyone seen something like this?
