Yeah the bit that goes into the graphics driver is called the vcgt.

Well, colord / GNOME Color Manager / GNOME Settings Daemon is as much
of a standard as exists these days. So you GNOME/Unity you can just go
the the Color Control Panel Applet and setup your color profile there.
It's super-simple.

If you're not not using GNOME/Unity things are harder, one way would
be to make a xdg .desktop file, like so (except for Argyll's dispwin
instead of xgamma):

Assuming you didn't generate the profile using GNOME Color Manager,
I'm wondering where you sourced the profile. Profiles supplied by
vendors tend to be not very useful (though exceptions exist).
