[X2Go-Dev] x2goruncommand is not exiting after logout in some distros

[Oleksandr Shneyder]

Hi all,

who wrote this in /usr/bin/x2goruncommand?:

---------------------------------------------
                 # This is gonna be a nasty trick now...
                 # Most applications run in foreground (fine!), but some 
fork to background (urgghh... e.g. konsole, iceweasel, etc.).
                 # By capturing their STDOUT, we force the process to 
remain in (sort of) foreground until the process has finished.
                 # This works fabulously with all applications that 
don't cleanly close their file descriptors (which is probably
                 # 99% of all applications out there...).

                 STDOUT=`$EXEC_WRAPPER $cmd$args`
------------------------------------------------

looks like some DEs for example XFCE and Plasma on Ubuntu22 and Alma9 
starting some processes which are occupying stdout and not terminating 
them after logout. As result after logout user have a blank screen which 
stays forever, that can be very confusing. We should remove it at least 
for desktop sessions. Replacing the line

STDOUT=`$EXEC_WRAPPER $cmd$args`
with
$EXEC_WRAPPER $cmd$args

fixing the problem.

regards,
Alex
