Thanks for joining the NUC community.
Intel does not test and validate Intel® NUC on Linux, however we know that a lot of NUC owners are using it successfully on many different Linux distros.
Intel suggests you check your Linux distro's website and forums at Linux Lite Forums - Index for peer assistance with this issue.
Really ? that's annoying .. I've been using it on Tizen until BIOS upgrade broke it ... btw what Free OS is Intel supporting for NUC ?
