journalctl log from crashed system
SUMMARY
Hi and thank you for developing plasma-mobile!
Here Mobian bookworm with plasma-mobile 5.27.2 on OG PP. Debian is now in hard
freeze, then we have to stick with 5.27.2 or cherry-pick any needed patch. Just
one change on my system with respect to Debian repository: kwin is patched with
[1].
>From time to time plasma-mobile happens to crash. I don't know exactly the
reason, maybe it's the long runtime, maybe when the session gets locked and
unlocked in short sequence.
In the attached logs:
18.03.33 resetting eg25-manager service in order to restart modem which had
lost carrier connection
then I pressed power key to lock session while waiting for modem to restart, as
it takes ca.20seconds
18.03.34 kwin_wayland_wrapper starts to spit out log messages like mad,
specifically
kwin_wayland_wrapper[1017]: kwin_core: Detected a touch move that never has
been down, discarding
gets repeated a lot
on the screen, after unlocking I get the usual white writing on black
background suggesting to unlock session from tty to recover situation
then I've pressed power key some times, that in my experience gets greetd (the
login manager service) to recognize session has crashed and to take over the
device's control: this happens around 18.06.04
