Re: MX-23 beta 2 feedback thread

What happens if you click on the bottom button "Clear Known Items"?
As I did't recieve any answer, even "I don't know (yet)", etc..
So I decided to investigate for myself. Sacrificed five hours until now. (I am not so effective as those, who know better where to search)
Here is, what I have found:
in Linux Mint the result is
Code: Select all

Code: Select all

ID 260 gen 127 top level 5 path timeshift-btrfs/snapshots/2023-07-01_22-00-02/@After reading this:
https://github.com/linuxmint/timeshift/issues/90
I checked kernel parameter
rootflags=subvol=@
It is set accordingly.
Timeshift still does not allow to use BTRFS in settings.
BUT: somehow (I almost never boot with SystemD) I got an idea to boot with SystemD,
and: Timeshift allowed to use BTRFS. Creating snapshot last unusually long time (about 30 secs), but the snapshot did not appear in the list in the GUI windows of Timeshift.
by checking I get

after few seconds by checking I get again

Again no line in the table.

I hope my discoveries will save the time for the developers.
Attaching logs, too.
Interesting info here (maybe not related to timeshift, but related to BTRFS and switching subvolumes for root):
https://bbs.archlinux.org/viewtopic.php?id=210582
Maybe a time to check different solution.
https://github.com/digint/btrbk
or
https://gitlab.com/btrfs-assistant/btrfs-assistant
Does somebody have experiences with BTRFS Assistant?
Does it work without SystemD?
Enough of Timeshift (without "F" ???
)
I don't know if anyone has reported VLC losing hardware accelerated decoding and encoding in Bookworm, but that seems to be unavoidable with the Debian packages.
