Freeze Screen

When Weston is started, there will be a black screen that switches between boot logo and UI display temporarily.

If you want to prevent this black screen, you can freeze the Weston screen content temporarily.

The following code block provides an example of adding warm-up to Weston's command options.

# /root/run_weston.sh
start)
...
weston --warm-up&

The following code block provides an example of freezing 1 specific display and unfreezing after 1 second.

# /root/run_weston.sh
start)
...
export WESTON_FREEZE_DISPLAY=/tmp/.weston_freeze 
touch /tmp/.weston_freeze
weston&
...
sleep 1 && rm /tmp/.weston_freeze& # unfreeze after 1 second

The following code block provides an example of freezing all the displays and unfreezing after 1 second:

# /root/run_weston.sh
start)
...
echo "output:all:freeze" > /tmp/.weston_drm.conf # Freeze the display
weston&
...
sleep 1 && \
echo "output:all:unfreeze" > /tmp/.weston_drm.conf& # unfreeze after 1 second
