For example, as per https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1369 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 i.e. I know what caused my instability, so surely there's a way to fix without a full wipe + install?!
