Handling Segmentation fault
Segmentation fault
libpng-tools and libpng16-16 are installed (seemed to be
the closest packages to the libpng error). worked before the
upgrade but broken after.
I suspect the update installed a series 5.4 kernel (uname -a )
You need to add QT_QPA_EGLFS_ALWAYS_SET_MODE="1" to the command
line i.e.
QT_QPA_EGLFS_ALWAYS_SET_MODE="1" QT_QPA_PLATFORM=eglfs
mythfrontend --logpath=/tmp -O libCECEnabled=0
You may need to reboot the Raspberry Pi before making this
change.

not sure about the seg fault - i reinstalled that rpi4.
i have a 2nd rpi4 that wasnt segfaulting but also not displaying the FE GUI even though it was running and i could even play recorded to (blink navigation). adding that to the start made the GUI appear. i'll have to double check this one as it worked fine last time i used it. maybe auto-updates are enabled and it got the 5.4 kernel in the last 2-3 weeks.
after rebuilding the segfault rpi4, it was same as the 2nd rpi - gui hidden and i needed to add that option to the cmdline startup.
Since the reinstall of the rpi4, it's being a bit erratic with boot up. not sure if it's a eeprom/firmware update causing it or i have a failing SD card but seems very intermittent boot where it wont even initiate the display.
thanks for that - the additional entry was needed! i'll update the wiki with it at some point.
