@Pedro - sorry for late answer, I was offline. I did not have read-edit and had to install it: sudo apt-get install read-edid
There is a problem with the command line: florin@florin-VirtualBox:~$ get-edid | parse-edid &> edid2.txt get-edid: get-edid version 2.0.0 mmap /dev/zero: Operation not permitted get-edid: error initialising realmode interface get-edid: do you have full superuser (root) permissions? And the file contains only this: parse-edid: parse-edid version 2.0.0 parse-edid: IO error reading EDID -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/841821 Title: Color manager shows [invalid UTF-8] To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/841821/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
