Hi,

you may have to install updated udev rules (menu “Tools” -> “Instrument”).

Hi, I cannot find such menu option. See screenshot

I solved with

# touch /etc/udev/rules.d/51-displaycal.rules

and I inserted into it

SUBSYSTEM=="usb", ATTR{idVendor}=="0765", ATTR{idProduct}=="6008", MODE="0666

and then

# udevadm control --reload

[germano]

I made a typo, corrected version
SUBSYSTEM=="usb", ATTR{idVendor}=="0765", ATTR{idProduct}=="6008", MODE="0666"

The correct menu entry is “Install Argyll instrument configuration files”. If the system provides its own, you may first need to uninstall that using the respective menu option (the system file will be backed up).
