Screen lock does not work by default. You can activate it following the instructions in this post by DoctorWkt (it worked in my Boox Max, so I guess it works an all Onyx devices):

The instructions above are for linux. Please, note that there is a little misprint in the Makefile. The correct code should be:
Code:
all: echo unpack pack
unpack:
rm -rf fs
abootimg -x boot.img
mkdir fs
(cd fs; zcat ../initrd.img | cpio -i)
repack:
(cd fs; find . | cpio -o -H newc | gzip > ../newinitrd.img)
abootimg --create newboot.img -f bootimg.cfg -k zImage -r newinitrd.img
clean:
rm -rf bootimg.cfg fs initrd.img newboot.img newinitrd.img zImage
