Hi,

could you get the log.txt from 'weston-launch &> log.txt' while
using weston master revision?
The fbcon stops updating the moment the rpi gfx backend
initializes (also in normal cases), but weston may still print
useful stuff after that.

What distro, are you locally logged in as the user 'pi', are you
using the real weston-launch binary (not script) which is
setuid-root?

When the screen hangs, and you get in via ssh, is weston or
weston-launch still running? What about weston-desktop-shell?
Are you then killing some processes and how?
(Hint: do not use kill -9 especially on weston-launch)


Thanks,
