From the maintainer:
I have seen this problem happen occasionally for various reasons. I think they have always been due to external factors. So I suspec
t that some external factor is the cause.
1st, what version of X2Go
Client are you using? For security fixes and bugfixes, you should be using 18.104.22.168+build2, but I will stil
l troubleshoot this issue for you even if you are not:
2nd, are you using 64-bit Windows Vista, 7 and 8 or 32-bit Windows Vista, 7 and 8?
3rd, is this option set in X2Go
Options -> Setttings -> X-Server settings -> use integrated X-Server
4th, do you have any other X servers running? The only freeware and FOSS X servers are VcXsrv (which we bundle and use), Xming 6.9,
and Cygwin X11. Commercial ones include Hummingbird/OpenText Exceed.
5th, can you try launching our bundled VcXsrv from the command-line and see if it launches successfully?
Run this command on 64-bit windows from command prompt:
"C:\Program Files (x86)\x2goclient\VcXsrv\vcxsrv.exe" -multiwindow -clipboard :0
or this command on 32-bit windows from command prompt:
"C:\Program Files\x2goclient\VcXsrv\vcxsrv.exe" -multiwindow -clipboard :0
VcXsrv should start successfully. You should not see any output in command prompt. However, you should see the X server tray icon sh
ow up. You can right-click the icon to end the X server.
Note that if VcXsrv does not start successfully, it should tell you that it wrote a log file with the errors. Please attach that log
file to the reply.
