When I selected external LCD and clicked "Create Profile for Device", calibration windows pops-up but closes after while and nothing happened. Version-Release number of selected component (if applicable): gnome-color-manager-2.32.0-2.fc14.x86_64 How reproducible: Always Steps to Reproduce: 1. Use two monitors in expand mode 2. Run gcm-prefs, select secondary monitor and click "Create Profile for Device" Actual results: Calibration does not start. Expected results: Normal calibration process. Additional info: I tested on Lenovo T500 and Dell 1703FP monitor with ColorVision Spyder2 Colorimeter. When I switched the T500 internal panel off, everything worked as expected.
Are you using a non-free driver?
No, open source driver for intel i915 (shipped in Fedora).
Finally got it to work, but it is not reliable. Seems to be argyll / spyder firmware related problem.
