in X2GoClient as well as two stand alone versions). With the X-server
provided by MobaXterm
(%USERPROFILE%\Documents\MobaXterm\slash\bin\XWin_MobaX.exe) everything in
fine.

It would be useful to known how to implement “adding "-noprimary" to the
VcXserv options” since when I attempted to add “-noprimary” to the vcserv
serve custom command line under X2Go->Settings when I restart x2go it now
_immediately_ crashes with “can’t start x.org.server” making my x2go setup
completely useless
