I am assuming you are using AXIS.
loadusr is required.
Please run from a terminal and post all the qtvcp messages.
EMBED_TAB_LOCATION is only for Gmoccapy, gscreen and qtvcp screens.

This almost works, IF the loadusr is removed, otherwise the qtvcp error
message says it's
looking in /usr/share/qtvcp/loadusr for cam_align.
The loadusr subdir does not exist. The camera is presently occupied so I'm
getting a blank white tab.
And halcmd now says invalid option "W"
Does it no longer need the EMBED_TAB_LOCATION line in the {DISPLAY} section?
Something else, that machine is running buster yet, and to synaptic,
qtvcp does not exist.
So is this bullseye advice only?
Thanks Chris.
