No window opens after starting the application

[mrkva]

Hi guys,

I have a serious problem with running anything OF on my Pi. I have installed codecs, dependencies. Compiled the core - all without problems (there was a problem while compiling ofColor.cpp at one point but I solved it by changing portion of ram dedicated to GPU to lower).

I have compiled the raspberry_hello_world example - also without any errors. But when I try to run it I get this:

Code: view plaincopy to clipboardprint? [ofAppEGLWindow::setupRPiNativeWindow:notice] screenRect.width==720, screenRect.height=480

And nothing happens. No window opens up, nothing. Is really the keyboard/mouse not being connected causing this?

I have to say I am using VNC to acces my desktop, because I don't have any physical monitor with HDMI/composite around. But that shouldn't matter, should it?

Thanks a lot for any tips!

Hey there, does the RPi then crash or become completely unresponsive? Or can you close the program?

If you check the activity monitor via top or a command like ps aux | grep hello is the program still running?

[bakercp]

Also, are you running the program from the command line or do you have X11 open (i.e. the desktop?) The preferred way to run programs is without X / Desktop open.

Program is running, I can kill it with ^C no problem (and it exits regularly). I am running it with desktop open, will try running without. Although - as I said I am using VNC to check if its working (don't have physical screen with hdmi/composite), so how would I attach VNC session to of app?

Thanks

Do we know if the x11 code runs on the pi? If you can find yourself an HDMI or DVI monitor or a RCA TV you should be able to run sans X11. On Apr 5, 2013 8:45 AM, "J. Zeleninsky" notifications@github.com wrote:

I answered similarly in the forums but I think VNC requires X11 and if the app is not an X11 Windowed app it will fail to display over VNC.

Another thing you can try is opt/vc/src/hello_pi/hello_triangle and see if that works over VNC.

[bakercp]

Wait -- are you saying that you don't see the window showing up over vnc? Since we aren't using x11-based windowing (we rolled our own EGL window), it may not come across vnc unless a monitor is attached.

Running with external screen instead of VNC+X11 solved to problem. Thank you!
