rpi5: eglfs does not work anymore (again)

[jcelerier]

Investigation:

• --no-gui isn't passed through anymore by appimage ? needs to be put in docs

-> drmModeGetResources failed (Operation not supported)

• https://stackoverflow.com/questions/64312387/rpi4-qt5-qml-drmmodegetresources-failed-error
  • eglfs.json: { "device": "/dev/dri/card1" }
  • export QT_QPA_EGLFS_KMS_CONFIG=/wherever/is/the/file/eglfs.json

-> Could not initialize egl display

• QT_QPA_EGLFS_INTEGRATION=none
  -> EGL Error : Could not create the egl surface: error = 0x300b

eglfs_kms plug-in was not being built due to lacking mesa-libgbm-dev in sdk
