Here's the scenario: I wrote gui using the python Kivy frame , and I want to run it on raspberry pi with this touch screen . I did an excellent installation, and the TSLIB_FBDEVICE=/dev/fb1 TSLIB_TSDEVICE=/dev/input/touchscreen FRAMEBUFFER=/dev/fb1 nohup startx &xwindow desktop is getting working. However, I could not get the qiwi-gi to work. I was able to get a tkinter test application that works fine, setting an environment variable DISPLAY.
I tried putting the following at the top of my kivy application, but to no avail:
os.environ['SDL_VIDEODRIVER'] = 'fbcon'
os.environ['SDL_FBDEV'] = '/dev/fb1'
os.environ['SDL_MOUSEDRV'] = 'TSLIB'
os.environ['SDL_MOUSEDEV'] = '/dev/input/touchscreen'
When I run my application, this is the debug output:
