Spotread. Summary Use an instrument to read a single color value.
This can be a useful diagnostic aid. Usage Summary spotread [-options] [logfile] -v Verbose mode -s Print spectrum for each reading. -S Plot the spectrum in a graph window. Usage Details and Discussion spotread operates in a similar fashion to chartread, but allows the reading of a succession of single color values. The -v flag causes extra information to be printed out during chartread operation. The -s flag enables the printing out spectral reflectance/transmittance values, if the instrument supports this. The -S flag enables the plotting of the spectral reflectance/transmittance values, if the instrument supports this.
The instrument is assumed to communicate through a USB or serial communication port, and the port can be selected with the -c option, if the instrument is not connected to the first port. The -e flag allows measuring in emission mode (e.g. displays or illuminants) using instruments that support this mode. Open-Source-Farbkalibrierung für Linux. Display Calibration on the Thinkpad W520 with Kubuntu and the internal Sensor. Today I tried to calibrate my display of my Lenovo ThinkPad W520 with the internal Colourimeter.
And I as far I can say it works. Now your question is, what do I need? Well, just download the Ubuntu dispcalGUI package for your distribution here. Then install argyll: sudo apt-get install argyll After that you can install the package you downloaded by clicking it or by using the terminal. (Example for i386, the 64Bit Kernel unfortunately has issues with ACPI on the W520) sudo dpkg -i dispcalgui_1.0.7.7_i386.deb Now you can execute the GUI. Sudo dispcalGUI #Using superuser rights Now you should see the GUI. First of all you should be sure to refresh all devices and to disable the interactive mode! And now to the only problem I found. So you may ask, what did you do, well I just closed the lid as far as possible before the screen is disabled and switched off the light in the room. (I post an update here if I find a solution, if you found one before me, feel free to post a comment) Now let's go on.

Zum Verständnis dieses Artikels sind folgende Seiten hilfreich: Dieser Artikel beschreibt, wie man seinen Monitor mit Hilfe des Argyll Color Management System für farbverbindliches Arbeiten profilieren kann.
ArgyllCMS besteht aus verschiedenen Kommandozeilen-Programmen, die mit Hilfe eines Kolorimeters Farbwerte, Kontrast und Gamma des Monitors messen. Dann wird die Abweichungen von der Norm gespeichert und danach die Darstellung auf dem Monitor so verändert, dass die Farben korrekt wiedergegeben werden. Über die Monitorprofilierung hinaus beherrscht Argyll noch viele andere Farbmanagement-Anwendungen (u.a. Wer eine grafische Oberfläche bevorzugt, sollte sich das Programm dispcalGUI anschauen (siehe unten). Hinweis: Um den Monitor mit dieser Anleitung zu profilieren, wird ein Messgerät (Kolorimeter) benötigt (z.B. Voraussetzungen Erforderlich ist immer das folgende Paket: icc-profiles (multiverse, Paket mit ICC-Farbprofilen) Linux color management. Linux color management has the same goal as the color management systems (CMS) for other operating systems: to achieve the best possible color reproduction throughout an imaging workflow from its source (camera, video, scanner, etc.), through imaging software (CinePaint, Digikam, GIMP, Krita, Scribus, etc.), and finally onto an output medium (monitor, video projector, printer, etc.).
In particular, color management attempts to support WYSIWYG (What You See Is What You Get) on-screen previewing (soft-proofing) ability for color work such as retouching prior to printing. Note that in practice, best is determined according to some algorithm and may not correspond well to what a human eye would consider best. Linux color management relies on the use of accurate International Color Consortium (ICC) profiles describing the behavior of devices such as digital cameras, monitors or printers, and color-managed applications that are aware of these profiles.
