Mramshaw mentioned dispcalGUI in a comment – while I was keeping an eye on lprof to offer a GUI for monitor calibration. So today I decided it was time to check how dispcalGUI does its job. And it does it well. Kudos to dispcalGUI’s author: Florian Höch
ArgyllCMS (blog 1, 2) is a Linux / Windows / Mac OS X set of command line utilities for color management – including but not limited to monitor calibration. So dispcalGUI is a make-your-life-easier frontend to Argyll which allows monitor calibration. This is especially handy since creating a profile with Argyll involves several steps with quite a few command line options – “dispcal -v -q l -y c samsung” anyone?
dispcalGUI comes blundled in a very “windows-like” installation package (and indeed, it works on MS-Windows, MacOS X and Linux). Just download the package, extract it and go through the installation process. You will need to point it to your Argyll installation, click a few “next” buttons and you are done.
Before srtarting using dispcalGUI, you need to plug your calibrating device and make it user writable (just like with Argyll). Type lsusb in a terminal to find your device busid and deviceid and then type:
sudo chmod 777 /proc/bus/usb/busid/deviceid
That will be it for the command line.
You can now load dispcalGUI. This is how it looks:
Functionalities are the same as Argyll’s – ie quite complex. DispcalGUI has a manual well written and quoting relevant part of Argyll’s – so RTFM. Otherwise, you can just check that the right monitor / instrument are picked. Chose your monitor type (LCD or CRT) and the calibration and profile quality. Leave the rest to default. Click on calibrate and profile.
After a (relatively long) time and a couple “y” or “any key” in the terminal, you will get an icc profile which you can load with dispwin or xcalib (for screen calibration) as well as your graphic application (for profiling – if the application supports it). Check this entry if you need to know more about color management.
And that, ladies and gentlemen, means one less item on the Linux & Photography todo list.
