How do/did you set up "full disk encryption"?

For me the chimaera installer only lets me reduce the disk to a single partition and encrypt that; is that what you mean?

But then, for me, the installer objects and goes into loop trying to force me to have a separate unencrypted /boot partition while not allowing me to erase the setup.

So, would you mind describing your "full disk encryption" (so I can trial it).

When installing the package usrmerge it will try to change the file system so that some root directories get changed into symbolic links for the same-named directories in /usr; those are what I call the "silly-links".

Unfortunately the usrmerge developers seemingly opted for going about this in the worst way possible, so the installation of usrmerge is likely to fail successively, requiring some amount of operator hands-on and reinstallation. Once installed, it gets replaced with the usr-is-merged package as indicator or flag for apt/dpkg to not install usrmerge again, ever.

All in all, it's better and almost necessary (esp for avoiding that operator hands-on) when shifting to excalibur, to install usrmerge on daedalus, i.e. before actually shifting. There is no technical difference difference between having or not having silly-links, except for the cases where a package installs binaries with a /bin path and then uses them on a /usr/bin path or vice versa (looking at you, busybox), in which case silly-links are required.

If you want to set up silly-links yourself you only have to make sure that the pathnames /lib* get copied and replaced with their links in "atomic steps"; i.e. you cannot use a shell script that separates "rm /lib" from "ln -sTf usr/lib /lib" specifically because the script intepreter's running of "ln" will require that the ELF-loader is found on its "/lib/.." path. (It's pretty obvious how to work around that though, for example by using busybox-static or , say, newlisp).

Argh! With the downloaded netinstall the failure is that "usr-is-merged" is unavailable.
I thought I had worked around that issue but obviously failed ... yes, failed to add that workaround to the commit.
Thanks for testing. There is a new collection (including that commit) coming up shortly.

Are you using "netinstall", "server" or "desktop" ? I'm using netinstall in a VM and have success with the hands-on I outlined. It you're using "server" or "desktop" I can check with those, though the installer software for the base system is meant to be the same.

Run the installation until that red screen, then push contine until the expert install menu comes up showing that you are on "Install the base system".

Now, step down to the "Change debconf priority"; select that and select the suggested "low" priority, which returns you to the expert menu and the "Install the base system" step.

Select that will now give you the option of choosing "yes" for silly-links, and that will then allow the base system installation to complete. Pick kernel and modules, and then use "go back" until the expert install menu again...

.... then it's just to pick your init, install grub, finish installation, and reboot.

Yes, no further testing is needed; there appears to be a mismatch between kernel and modules for excalibur so it won't work. Thanks for trying.

Possibly because it depends on $syslog which isn't started in the rcS collection.

Could be. But I think the OP issue is at the "audio server" end rather than the device end. At least that's how I remember it although I don't remember the details.

By one web search and a little bit of reading I found
https://forums.linuxmint.com/viewtopic. … 4#p2333570

Though I suppose you've also done such trivial a search, found that posting, tried that already and failed?

As far as I understand that description, the error is that the device gets setup with wrong audio profile. And then that the "Bluetooth connection fiddling GUI" only offers a change to that while connection is happening (before it fails).

Which audio proile is it set up with?
Is that a profile that the dongle has?
Have you tried using other profile(s)?

There was a bug in logind0 where it, upon exiting the seat, changed the ttyN owner to be root and that resulted in the user not being able to run startx a second time (that bug was inherited from the s*d code where it had been logged and resolved as a "won't fix" issue).

Though I don't remember the versions involved off-hand, and I believe the fix got into daedalus so  your "freezing problem" is likely something else. If you have any "side entry" (ssh or something) to the host you could check. That bug was only with elogind and not with seatd.

Try by adding a single "#" at the beginning of the line that says use-ssh-agent in /etc/X11/Xsession.options; then log out and in to restart the X session.
