Hi – I have just installed DisplayCal 3.2.3 on Centos 7.

I installed argyll manually copying the binaries to ~/.local/bin and then installed DisplayCal using Rpm.

All seems to run fine but eventually I get an error “Error – display read failed with “”Instrument Access Failed”

My user is in the wheel group.

You need to install the Argyll CMS instrument udev rules, see the Quick Start Guide in the documentation.
