[Trisquel-users] Re : Abrowser as another user

That is strange.  Nowadays, the launcher should be the same whatever the  
desktop environment.  In this case, it executes the command synaptic-pkexec,  
a one-line shell script:
#!/bin/sh
pkexec "/usr/sbin/synaptic" "$@"
What happens if you execute synaptic-pkexec in a terminal.  Any error  
message?
