Weston Freeze Screen
When Weston was started, there was a black screen for a short period switching between the boot logo and the UI display. If you need to prevent a black screen, you can temporarily freeze the Weston screen content through the following dynamic configuration file methods:
# /etc/init.d/S50launcher
start)
...
export WESTON_FREEZE_DISPLAY=/tmp/.weston_freeze # Set the path of the special configuration file
touch /tmp/.weston_freeze # Freeze display
weston --tty=2 -B=drm-backend.so --idle-time=0&
...
sleep 1 && rm /tmp/.weston_freeze& # Thaw in 1 second
