Also, can you please retry using the current developer version of nx-libs as described here: http://wiki.x2go.org/doku.php/doc:howto:nx-libs-betatesting
I finally got around to getting as far as I could trying to build a rpm for nx-libs 3.5.99.4 under RHEL 7 based on instructions at https://github.com/ArcticaProject/nx-libs/blob/3.6.x/README.md, but I get an error "File not found: /builddir/build/BUILDROOT/nx-libs-3.5.99.4-0.0build1.el7.centos.x86_64/usr/share/nx/fonts" no matter what I do. There is no such directory under RHEL 7.
I had the opportunity to try the Windows x2go client on a different computer to remote into my server. In that case, x2go correctly used the full resolution of the physical screen on the client computer, which I believe was something like 1920x1080. Anyone have further ideas?
