I have an embedded Qt application crosscompiled that runs on BeagleBone Black. It works Ok, but one thing- It doesnt accept keyboard input if i wont run in directly on Beagl

Answer 1

I also facing this issue. But in my situation, I use remote desktop from Windows OS to raspberry / beaglebone.

My solution (make sure at least you know how to configure ssh in raspberry) :

1. install xrdp (sudo apt-get install xrdp) on raspberry / beaglebone / other embedded linux
2. in PC instal xming (search sourceforge)
3. open XLaunch, select multiple windows > start no client > clipboard > finish
4. open putty >> session, enter host name / IP address, putty >> SSH >> X11 >> check 'Enable X11 forwarding' putty >> click Open button
5. login ssh and then type qcreator

now the keyboard should be fine
