I googled a lot but no answer found yet. > What do you mean by 'from the debian bash'? Normally, you're sitting in front of a graphical desktop (i.e. running the X server or Wayland) displaying a terminal emulator (e.g. XTerm) that runs a shell (e.g. bash). The shell command (e.g. xclock) starts the process that issues X11 commands that go to the current $DISPLAY and show up as windows. If you're not running the X server, i.e. sitting at the raw text terminal console (all black screen with white text), you cannot and will not see graphics. The older system with similar software runs fine from autostart. Maybe I > need to do here as well?

Usually it is done by asking it to go to the graphical run state (5 in the old sysV init scripts, graphical.target in systemd) For debugging, you can type 'startx' to start X manually. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
