So here you're running the xrandr command and getting output from it, right? > > Here the important point is that, now in my desktop terminal, I cannot enter > the xrandr command, because there is no command prompt ( ie # ) in the > terminal. OK, so the terminal program is not set up right. I see that you're using openbox, which is a window manager. I am not familiar with it, so I don't know what do you do in openbox to start programs, but you need to start a terminal emulator and arrange for a shell to be run within that emulator. This is normally done automatically, but clearly in your case something is choking up. I don't know what terminal emulators are available on your system, but you need something like xterm, gtkterm or lxterm. Perhaps https://bbs.archlinux.org/viewtopic.php?id=155127 has some advice that you could use. > Now as Przemek suggested, I included the command 'xrandr' in ~/.xinitrc, > before ./simpleQt (name of my simple Qt application). > > But the execution of this command is observed in either desktop display or > display connected to BBB.
