Hi and thank you Graeme for this great piece of software.
I have run into a problem when trying to calibrate the screen of my
Thinkpad SL510 in Ubuntu 16.04.1 Xenial
The current package version is 1.8.3+repack-2
The instrument I use is a Colormunki Smile
Calibrating used to work in Ubuntu 14.04 Trusty
This error has persisted since Ubuntu 16.04 first came out, a different
Thinkpad model (X220) yields the same error.
Below is a dump from trying to calibrate, please excuse the extraneous
single quotes.
Additionally, at the bottom, there's some dmesg output.
Any ideas on how to proceed from here?
Best regards.
