Package: x2goclient
Version: 4.0.5.0
Severity: normal

Hi,

X2Go Client sometimes fails to create the xinerama.conf file in the  
server-side X2Go Session directory. This only happens, if screen  
coordinates have negative values (which happens when software-side  
swapping the client-side monitor layout via xrandr calls).

See error log below (from x2goclient --debug).

Mike
