Here is the result of uname -a:
pi@w3yj-pi4-old:~ $ uname -a
Linux w3yj-pi4-old.ddns.net 5.4.79-v7l+ #1373 SMP Mon Nov 23 13:27:40 GMT 2020 armv7l GNU/Linux
This can’t be good, I get a core dump when checking the nxplayer status:
pi@w3yj-pi4-old:~ $ /usr/NX/bin/nxplayer –dialog status
Segmentation fault (core dumped)
Would the core dump be of any value to you? Unfortunately it is too large to upload to the forum.
