Strange boot problem

I don't know. I may have done so, but if so it was not intentional. At any rate, I got back to the desired desktop with the standard system settings.

Here are the requested subvolume lists:

I don't know if it is of any value, but one phenomenon that i have noted is that if I do a restart (or shutdown and restart) and then -- rather than let the system just do its 5 second countdown and then boot, -- I go down and select a snapshot -- it will simply not do it. It will show the snapshot and some info lines below that, but if I then select the snapshot (top line) it will briefly look like it is going to load then just jump right back to the same page -- i.e. will not load

You posted twice the subvolume list. Please post

sudo timeshift --check

I'm just willing to check JSON file errore, since I remember from the past some timeshift issues due corrupted JSON files.

Here is what you asked, sorry for last wrong post:

╭─[email protected] in ~
╰─λ sudo timeshift --check
[sudo] password for kenb:
Using system disk as snapshot device for creating snapshots in BTRFS mode

/dev/sda1 is mounted at: /run/timeshift/backup, options: rw,relatime,compress=zstd:3,ssd,space_cache,autodefrag,subvolid=5,subvol=/

Daily snapshots are enabled
Last daily snapshot is 4 hours old

This probably won't help, but I've just received an update for grub-btrfs, the package that creates the snapshots sub-menu.
Try to update, just in case...


Thanks for suggestion. Made some improvement in this sense:
(A) Still will only sporadically get past Kde freeze if i simply allow the countdown timeout/autoboot, but
(B) If I arrow down and choose a snapshot and then on the popup click on either of the lines below the top (both almost the same but one one includes word "fallback), then the system will boot OK.

Whenever it does finally boot, everything works perfectly, and I love it, so I would dearly love to get past this little startup irritation. I sure do appreciate the efforts you all have made.
