I don't understand how the update could solve this. But well... maybe that Paulo mention to EDID and if the information is there.

Logical because the port is internal to a multi-function DP device (it contains both a branch and a sink). DP spec says logical port numbers start from 8. ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx

Keep in mind that due to adapters, the actual cable connected to a certain port may change over time, and our Kernel connector names are fixed. The most user friendly thing apps can do is to read monitor information (from EDID) and display that to the user. For example, I see my desktop environment says I have "Acer Technologies 27"" and "Laptop" (and it even displays which one is which). I don't even need to care if the monitor is connected through HDMI or DP: all I have to know is what I can see (the monitor itself). > > -- > > "Wisdom is supreme; therefore get wisdom.

From the driver perspective the protocol is the most important part, but that gets sometimes really bad for the users, I know. Honestly I don't know if there's a way to detect the presence of adapters like this DP to VGA for instance. I don't think so.
