Hi, I use a docking station for my x240t. It's a "Thinkpad Ultrabase Series 3" P/N 0B67692. It has a ton of ports including a HDMI port, which shows as HDMI2 under X11. The problem is, this port only becomes usable after a suspend and resume cycle. This is awkward since I move between different monitor configurations frequently.
I've spoken to matthieu@ and jsg@ about this briefly, but we did not find a fix. I'm posting here in case others have any ideas. See below the output of xrandr before and after zzz, and also a full dmesg.
