I forgot to mention by the looks of your link is testing currently only working on debian based systems? We’re using Rhel6 systems with x2goserver installed on them. I did notice in the git repo for Artica nxlibs there is a section for building out a rpm. Little out of my depth here though so I might be not looking at the correct thing. > On Jan 9, 2017, at 11:58 AM, Town, Brian A.

If I use basic Xforwarding through the terminal I get the colors I need displayed properly.

With a support contract, you get guaranteed response times (starting at 400 EUR/month for 24h response time during business hours in the CET/CEST time zone from Monday to Friday, German holidays excluded) and lower hourly rates if you buy a certain amount of hours in advance. > </shameless plug> > > Kind Regards, > Stefan Baur > > Am 09.01.2017 um 15:13 schrieb Town, Brian A.
