1.5.12: using cygwin/x as non-administrator doesn't work

[Tobias Munk <munk at zedat dot fu-berlin dot de>]

Using cygwin/x administrator works fine, but when I try to start it as 
user, I get an error message - the log file XWin.log is attached at the 
end of this mail.

There is a similar mail concerning this issue in the archive, which 
was posted a year ago, but seemingly no one posted a solution. Does anyone 
gather experiences with this in the meantime?

thanks,

Tobias
