[tde-users] Hibernate works on "bookworm" but not on "trixie"

On the same laptop (Thinkpad X390) hibernate works (from Trinity powersave) MX-23/bookworm but not on MX-25/Trixie.

From the cli pm-hibernate on MX-25 seems to shudown (I must login again). HIbernate from TDE-Powersave locks the screen but bothing more.

From the cli pm-hibernate does *not* work (nothing happens, no error message). Hibernate from TDE powersave locks the screen, then powers down. Resuming goes back to the locked screen and then restores the desktop correctly.

MX-23 has sysvinit and systemd installed but not activated, MX-25 has either sysvinit (my case ) or systemd. Can this be an explanation?
