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:
