I have 2 Display running with TX1 R24.2.1.
- HDMI Monitor (1920x1080)
- eDP panel (1920x1200)
Below is my xrandr output
ubuntu@tegra-ubuntu:~$ xrandr Screen 0: minimum 8 x 8, current 3840 x 1200, maximum 16384 x 16384 DP-0 connected primary 1920x1200+1920+0 (normal left inverted right x axis y axis) 220mm x 140mm 1920x1200 60.02*+ HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 480mm x 270mm 1920x1080 60.00*+ 59.95 50.00 61.25 60.05 51.04 1600x900 60.00 1440x576 52.08 1440x480 62.69 1280x1024 75.03 60.00 1280x720 60.00 59.94 50.00 1152x864 75.00 1024x768 75.03 60.01 800x600 75.00 60.32 720x576 50.00 720x480 59.94 720x400 70.04 640x480 75.00 59.94 59.94
By default, Both display appear as side by side as extended display.
In my application, i required my primary display as eDP where my application GUI is running.
At startup HDMI monitor should be OFF or should be displaying some logo without mirroring my GUI application. I just want to display Gstreamer Camera Preview on HDMI on request.
How can i start any application on a particular display (eDP or HDMI) from command line and also from my QT GUI app?
If you guys have any better idea for nVidia TX1?
