I'm starting the mythfrontend using a modifies pi-utils
run_mythfrontend.sh so the command as modified is:
QT_QPA_EGLFS_ALWAYS_SET_MODE="1" QT_LOGGING_RULES=qt.qpa.*=true
QT_QPA_PLATFORM=eglfs
QT_QPA_EGLFS_KMS_CONFIG=/home/ubuntu/pi_mythfrontend.json mythfrontend
$ARGUMENTS
Adding the QT_LOGGING_RULES didn't let the mythfrontend run at all but
after it exited the keyboard was dead. I already added user ubuntu to
group input.
The console log is:
