Anyway, I downloaded this package directly from the mirror's pool: linux-image-4.19.0-10-amd64-unsigned_4.19.131-2_amd64.deb Is the above package correct? And the good news is, this kernel also works fine :-)
I tried something similar, but am having mixed results. I added "buster-proposed-updates main" to sources.list, and installed linux-image-4.19.0-10-amd64. Which I think should be the same as Aaron Lu retrieved, except I have the signed variant. I installed on a Panasonic CF-19 laptop running Debian 10.4 and xfce.
Recovering from screen blanking and locking does work with that version of the kernel. So, on my computer, it does work better than the standard buster kernel 4.19.0-9. However, suspend and hibernate still don't work. I haven't had a chance to try Aaron Lu's suggestion of backported kernel 5.6.0. However, I have been using 5.4.0 for a while, and blanking, locking, suspend, and hibernate all work with that version.
Hope this information is helpful.
