Haha I have tested a few different compression/slider options but still going th= rough 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 x2= go provides me with the correct color, however it also produces a great dea= l of lag. Is the local desktop option doing basic VNC connection or Xforwar= ding? I couldn't find any information on that. I'm utilizing x2go in conjunction with a LTSP set up. If I use basic Xforwa= rding 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? Som= e blogs I've noticed people their session.log files showing unix_kde_depth3= 2 however mine is always at 24 and unsure where that setting would be locat= ed at.

(GSFC-428.0)[Embedded Flight Systems, Inc] ; 1132@bugs.x2go.org Subject: Re: [X2Go-Dev] Bug#1132: Color issue with x2go not present in NX w= ith certain applications Hi, Brian! First of all, welcome to X2Go! You're actually the third NASA employee hit= ting 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: 1) Please let us know the name of the software that has these issues with X= 2Go; if it is non-free and/or something NASA developed internally, you migh= t 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. 2) Please try different slider settings and image compression algorithms in= the connection settings. Maybe it only affects JPG, or only PNG, ... 3) Also, please try running the software with X2Go in single application/pu= blished application mode (IOW, rootless mode) vs. fullscreen/windowed mode. This is becahse parts of the screen drawing proc= ess work differently in rootless mode. 4) 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 chan= ges 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 distributi= ons, not for Redhat - but if you have a test lab available to you, you coul= d "ssh -X brian@redhat-test-box" from the Debian box within the X2Go sessio= n.) 5) We'd love to hear how you use or intend to use X2Go, so we can publish y= our testimonial on our success stories page in the wiki. Since you seem to be working with weather satellites, that sounds like a ra= ther interesting use case for X2Go. Last, I hope you don't mind that I mention this ... X2Go also has a commercial side, where various companies - including my own= - offer support contracts with guaranteed response times as well as consul= tancy 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: 1) I'm the current X2Go Project/Community Coordinator, so the development l= ead and the developers tend to listen to me. 2) As far as I know, we are the only company providing X2Go support that is= n't a one-man-show. 3) We sub-contract other developers from the X2Go community on demand, so y= ou only have one person you need to talk to - me - and you will only receiv= e one invoice, even if the task involved several freelance or part-time X2G= o 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 hour= s 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.
