Hi Brian,
I was under the impression that at present, they only support Debian and its derivatives, but maybe that has changed. Let's see if we can get an Arctica developer (see CC) to chime in and comment on the feasibility of testing X2Go together with the Arctica NX-lib nightlies on RHEL6. :-)

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.

I have tested a few different compression/slider options but still going through and see what each option gives me in. The software being used is open source for NASA missions I believe but closed outside of that, so not sure what all I can share on that just yet, I'll have to check.
I did notice that selecting the "local desktop" option via the client on x2go provides me with the correct color, however it also produces a great deal of lag. Is the local desktop option doing basic VNC connection or Xforwarding? I couldn't find any information on that.
I'm utilizing x2go in conjunction with a LTSP set up. If I use basic Xforwarding through the terminal I get the colors I need displayed properly. I'm not sure exactly where it's hanging up through the x2go client window.
For the unix_kde_depth option, is there a setting to have it exceed 24? Some blogs I've noticed people their session.log files showing unix_kde_depth32 however mine is always at 24 and unsure where that setting would be located at.

Hi, Brian!
First of all, welcome to X2Go! You're actually the third NASA employee hitting our list (the other two were from JSC-EG311 and JPL-392K). Sorry, that doesn't mean you've won a prize. ;-)
Some things I would like to ask you to do/try:
Please let us know the name of the software that has these issues with X2Go; if it is non-free and/or something NASA developed internally, you might want to get the developers of that software involved as well so they can talk to ours. Screenshots would help, too - but please remember to black out confidential information that might be visible on it.
Please try different slider settings and image compression algorithms in the connection settings. Maybe it only affects JPG, or only PNG, ...
Also, please try running the software with X2Go in single application/published application mode (IOW, rootless mode) vs. fullscreen/windowed mode. This is becahse parts of the screen drawing process work differently in rootless mode.
If you have a chance to run this software along with X2Go in a separate testing environment, you could try following these steps and see if it changes anything - but please do not do this on a production system: http://wiki.x2go.org/doku.php/doc:howto:nx-libs-betatesting (Note that at present, this probably only works for Debian-based distributions, not for Redhat - but if you have a test lab available to you, you could "ssh -X brian@redhat-test-box" from the Debian box within the X2Go session.)
We'd love to hear how you use or intend to use X2Go, so we can publish your testimonial on our success stories page in the wiki. Since you seem to be working with weather satellites, that sounds like a rather interesting use case for X2Go.
Last, I hope you don't mind that I mention this ...
<shameless plug> X2Go also has a commercial side, where various companies - including my own - offer support contracts with guaranteed response times as well as consultancy and paid-for development work if someone wants to see a bug fixed or a new feature added in a certain time frame. What makes my company special is, IMHO:
- I'm the current X2Go Project/Community Coordinator, so the development lead and the developers tend to listen to me.
- As far as I know, we are the only company providing X2Go support that isn't a one-man-show.
- We sub-contract other developers from the X2Go community on demand, so you only have one person you need to talk to - me - and you will only receive one invoice, even if the task involved several freelance or part-time X2Go developers.
Our hourly rate for consultancy work and fixing issues outside of a support contract is 110 EUR. 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

Package: x2goclient
Version: 4.0.5.2
Connecting to remote RHEL system using x2go has color issues with certain panels of an application on that system. When connecting via NoMachine the panels show up as they should, black background, white text. However with x2go the panel shows up as a grey background with black text, and some text are just black boxes (the major issue is the black boxes obscuring text).
I noticed a bug along these lines from back in 2013 (#262 ) (http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=262)
