True. I could just make up a use case, that I set up GNU/Linux for
someone without giving them the root password. Then some external
monitor/TV does not work and to debug the problem I want to know what
quirks are present in the running Linux version.

Also possible user space programs (for GNOME, KDE, …) should be able to
query such information without being root. Maybe even `xrandr` is
suitable to display such kind of information.

We should also keep in mind that an user can change resolutions with
`xrandr` already today.

True. And I cannot think of a reason how knowing these information
should hurt. But it reminds me of Linus’ security rant [1].


Thanks,

Paul
