Hi Przemek, My original question was regarding xrandr command.
Now I am able to open a window as per a small qt progam in the LCD display. But still xrandr is not showing the outputs. It is showing no protocol specified. root@localhost:~# xrandr No protocol specified Can't open display :0.0 root@localhost:~# Am I missing something? Thanks for the help.
