How to run two X servers together, each with its own layout, directly from command line, without any display manager (e.g. GDB, KDM or LightDM)?
Lets say there are two ServerLayout sections in xorg.conf. One with Identifier "seat0", second with "seat1". Then one can run a specific seat for example with one of these commands:
$ startx -- -layout seat0 $ startx -- -layout seat1
But these commands cannot be executed together! I do not know why but it does not work. (I am also curious what is a problem here?)
The reason why I am trying to leave out a display manager is because of debugging. When multiseat configuration does not work, it is difficult to find out whether there is a problem with a display manager configuration or driver perhaps.
