Re: [gentoo-user] semi OT: Displayport
Thanks for the link, looks like its going to be "fun" :) - I think using an inotify file watcher might be the best/low resource way to detect the event.

[gentoo-user] semi OT: Displayport
Hi all, I have a surface4 pro and use a vga adapter on the displayport connection. This works when manually (Xorg, XFCE4 and xrandr) configured to various external monitors and data projectors. I am trying to automate the process but plugging in the display port adapter does not generate any messages via logging or dmesg (kernel is gentoo-sources-4.16.12 patched to work with the ipts touchscreen) to hook a udev rule into. Can anyone suggest a way to detect when the displayport adapter is plugged in? BillK
