Also figured out why #spawnOn to start a window on a specific #workspace did not seem to work properly in my #Xmonad tiling window manager setup. Switched from #lxterminal to #xfce4-terminal. The latter has a "disable-server" option to use one process per window. The former or gnome-terminal don't have this option (anymore). However a per window process seems necessary for Xmonad's spawnOn. Now also integrated some more autostarting of stuff into my Xmonad setup.
