May 13. 2023 UPDATE same issue back again on Bookworm RC2
As I use my Thinkpad X1 Yoga (is detected as X1 Carbon 4th gen) also as
test machine, I made a fresh Bookworm install and had the same issue
(even worse) as on Bullseye. I say worse because on bullseye the issue
was at least visible, as the screen didn't power off completely. But now
on Bookworm the display power off... but not the machine. This is why I
even didn't realize it after installation... but only when my TP didn't
want to start 2-3 days later... the battery was drained off!
After recharging, I it saw that after shutdown, only sign was that the
small led on the ESC/FnLk key was still on! Something that I didn't see
earlier when closing the the laptop lid.
I added, as per Felix Rublack recommendation, the same entries in
/etc/modprobe.d/blacklist-tpm.conf (Message #40),
blacklist tpm
blacklist tpm_crb
blacklist tpm_tis
blacklist tpm_tis_core
but unfortunately this doesn't work on Bookworm!
As I'm a relatively new Linux/Debian user with limited knowledge I would
appreciate any suggestion how to solve the problem.
Thanks in advance for any suggestion!
