Hi,

it's normal that weston-launch sleeps in poll(). What makes you think
it's stuck? Has it not launched a Weston process?

If a Weston process exists, maybe it's Weston malfunctioning and not
weston-launch. Mind, that printing to the VT stops working when
Weston/DRM starts, but Weston is still printing. You might get more out
of it by redirecting stdout and stderr to a file.

FWIW, weston-launch no longer exists upstream. That use case is now
catered by libseat and seatd.


Thanks,
