I am looking to boot up our Tx2 board. It boots up, and I see the screen on an HDMI monitor. I am sharing the monitor between my computer (host / ubuntu machine) and Tx2. When I connect/switch monitor from Tx2 to my computer, and then try to connect it back to Tx2, the HMDI monitor would not connect back to Tx2.
I am able to ssh into Tx2 from computer. Thus I know that Tx2 is alive.
Upon some looking around I see that this has been discussed few time before

It seems I need to modify hdmi2.0.c in kernel, and recompile it. I am wondering if this issue has been summarized somewhere with few simple steps enlisted as remedy ? I am unable to fathom what next steps should be ? Can I get by with simple reinstallation of hdmi driver, or patch from nvidia ?
