There was a problem hiding this comment.
rather should be checking that uid == 0.

-dito allow specifying the display by its ID instead of its (arbitrary, non-permanent) list index.So far,
-dwas the only way to specify which display to send commands to. This refers to the list index of the display. Unfortunately, sometimes, depending on extraneous factors such as the order in which displays were plugged in, the order of the list changes. In order to reliably specify the same display every time, I added the-dioption that allows the user to specify thedisplayIDas shown byddcctl. At least on my setup, this ID remains constant.To test this feature, run
ddcctlonce to see the availabledisplayIDvalues on your system. Pick one, runddcctl -di <DISPLAY_ID>. It acts the same as if you didddcctl -d <POSITION_OF_DISPLAY_IN_LIST>.This fix might also be a viable workaround for #85.
