I have calibrated my yellow screen using argyllcms. I don't attach usb devices to dom0 so installed it in sys-usb as well. used https://encrypted.pcode.nl/blog/2013/11/24/display-color-profiling-on-linux/ as a rough guide. to get the calibration done you just need to run dispcal and then transfer the calibration file to dom0. then test it with "dispwin xxx.cal" in dom0. if happy, create an autostart item with that command (probably, using the full path to the calibration file) and you're done.
I went further and created an icc profile for use in firefox and photo software. note that some displays use proprietory colour-mixing algorithms so Linux tools may be ineffective with them :( (e.g., pentile matrix on some very high resolution screens) -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
