Kodi starts and runs but only a black screen is displayed

i can start kodi and I see kodi.bin running, but only a black screen is displayed. Issuing a `killall kodi` returns me to my desktop (lxqt). Any thoughts are welcomed. Thanks!

I have enabled debugging and the log is here.

Code:
% cat ~/.kodi/userdata/advancedsettings.xml
<advancedsettings>
    <loglevel>1</loglevel> <!-- Change this to "1" to hide the on-screen debug log text -->
    <debug>
        <extralogging>true</extralogging>
        <setextraloglevel>32,64,128,256,512,1024,2048,4096,8192,16384,32768,65536</setextraloglevel>
        <showloginfo>true</showloginfo>
    </debug>
</advancedsettings>
