Support for Waveshare touch display

[Dereen]

Hello,

I would like to ask what needs to set for raylib, to correctly detect new display.

I have Raspberry Pi 4, with display https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(A)

I followed https://github.com/raysan5/raylib/wiki/Working-on-Raspberry-Pi and installed raylib library by command make PLATFORM=PLATFORM_DRM. Everything has builded correctly, even examples. Rpi was connected by HDMI cable to my PC monitor and example ./shapes_basis_shapes showed up correctly on the PC monitor.

Then I followed steps for display https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(A). Terminal showed up on display after reboot. Trying run ./shapes_basis_shapes again failed with output:

INFO: Initializing raylib 38.-dev INFO: DISPLAY: No graphic card set, trying card1 INFO: DISPLAY: Failed to open graphic card1, trying card0 WARNINGL DISPLAY: Failed to open graphic card FATAL: Failed to initialize Graphic device

Thanks for help
