I have a few installations of rstudio
https://www.rstudio.com/products/rstudio/download/#download
running on Fedora 26, Centos 7.4 and Red Hat Enterprise 7.4 x2go server:
x2goserver-4.0.1.20-2.fc26.x86_64 x2goserver-4.0.1.20-1.el7.x86_64
With the these two x2goclient on Fedora 26: x2goclient-4.1.0.0-1.fc26.x86_64 x2goclient-4.1.1.0-1.fc26.x86_64
rstudio will segfault on startup.
Any other x2goclient I've tried, 4.1.0 on Windows and 4.0.5 on Mac, rstudio works no problem. Also doing "ssh -Y" to the hosts running x2goserver, rstudio starts with no problem.
rstudio has worked in the past (maybe several months ago). Perhaps I was using Fedora 25 then. So I'm guessing that it's something to do with the x2goclient on Fedora 26.
Any ideas?
On trying to start rstudio inside an x2gosession the segfault looks like: $ rstudio QXcbConnection: Failed to get the primary output of the screen Unsupported screen format: depth: 24, red_mask: ff,

I think I found a fix. From this thread:
http://www.bioinformatics.org/pipermail/bio-linux-list/2015-March/000804.htm...
Where it says:
Tim discovered that this was caused by the Qt binaries bundled in the RStudio .deb. A similar fix might work for you:
cd /usr/lib/rstudio/bin mkdir notused mv -i libQ* notused/ mv -i qt.conf notused/
As shown, I moved aside those rstudio Qt libraries on my Fedora 26 and Centos 7.4 x2goservers. Also installed qt5-* on the f26 and centos 7.4 x2goservers
After that connecting from my Fedora 25 x2goclient, rstudio did not segfault and seems to work.

I have a few installations of rstudio
https://www.rstudio.com/products/rstudio/download/#download
running on Fedora 26, Centos 7.4 and Red Hat Enterprise 7.4 x2go server:
x2goserver-4.0.1.20-2.fc26.x86_64 x2goserver-4.0.1.20-1.el7.x86_64
With the these two x2goclient on Fedora 26: x2goclient-4.1.0.0-1.fc26.x86_64 x2goclient-4.1.1.0-1.fc26.x86_64
rstudio will segfault on startup.
Any other x2goclient I've tried, 4.1.0 on Windows and 4.0.5 on Mac, rstudio works no problem. Also doing "ssh -Y" to the hosts running x2goserver, rstudio starts with no problem.
rstudio has worked in the past (maybe several months ago). Perhaps I was using Fedora 25 then. So I'm guessing that it's something to do with the x2goclient on Fedora 26.
Any ideas?
On trying to start rstudio inside an x2gosession the segfault looks like: $ rstudio QXcbConnection: Failed to get the primary output of the screen Unsupported screen format: depth: 24, red_mask: ff,
