For the cases where kmscon actually fails (exit with a non-zero code),
a solution would be the following: instead of running kmscon directly,
we run a wrapper around it that spawn mingetty (as you suggested) when
kmscon exits with non-zero.
(Perhaps the flickering Joshua mentioned was actually due to kmscon
being continuously restarted by shepherd?)
However, in cases where kmscon does *not* exits and simply produces a
black screen, I don’t see what can be done. In the cases you list
above, does kmscon simply sit there without exiting?
At any rate, thanks for the testing & detailed info!
Ludo’.
