Du you use wayland? If so, try Plasma on X.
In my VM i can't start Plasma Wayland after the update.

The use of smartmontools with NVMe is still experimental: https://www.smartmontools.org/wiki/NVMe_Support

Thanks, devil.

I suppose not.  I never tried to switch and I don't have 'plasma-workspace-wayland' installed...

Since there were updates today, I decide to try again (after updating), but it did not work.

On the other hand, I decided to try Wayland and it did work!  Since it seems Wayland is not mature enough, I'd rather go back to X...  But if I can't, at least I have a way to get to KDE.  (Or I can stick with fluxbox or LXQt....)

Provide a Xorg-log from a failed start.

Hmm...  Now, after being able to log in with Wayland, I can also log in with X.  (Typing from it right now.)

Code: [Select]
$ echo $XDG_SESSION_TYPE
x11


 I have no idea what happened.  (As I said, I tried to login after the update but did not work.)

Could it be the newer kernel?  (I tried logging in right after the update, so the kernel running was not the current one: 5.10.3-towo.2-siduction-amd64.

I will try to log in with the old one(s) and see if I can still log in.

In any event, here is the last X log, before the current successful log in with X, but after logging in with Wayland.  (I don't know if Wayland uses a different log or not.)

OK, things are weird....

Indeed, the previous kernel linux-image-5.9.15-towo.1-siduction-amd64 failed to start KDE.

Then, I restarted with 5.10 and could *NOT* log in (with the same problem), but after a reboot (to 5.10 again) I could.  (Using it right now.)

I will try to get a log with a failed boot from 5.9.

I can't seem to get a log from X when it fails...  It seems that it is either not recorded or overwritten with a new boot.
But here is the .xsession-errors file from a failed log in: https://pastebin.com/8W5k3FmM  (Sorry for using pastebin, but paste.debian.net did not allow me to post a new file...)

Where you have looked for a x-log?

In /var/log/Xorg.0.log.  My aptosid has also /var/log/Xorg.1.log, which I assume has older logs, but this siduction system does not.

I tried moving the Xorg.0.log to capture a "fresh" error, but when I logged in again after log it was empty.

Indeed,  after a few tries, I cannot capture an Xorg.0.log.  Whenever I reproduce the error, the file comes out empty.


And, by the way, Wayland + kernel 5.10 was a fluke, it seems, as it does not work anymore (and neither does X + kernel 5.10).  (sddm starts without problem, though.)

I can still login fluxbox everytime without problem.

FWIW: with the new ISO (with Plasma 5.20 and 5.10 kernel) I can login in Plasma with no problems.  (I did it 3 times to make sure.)

I was expecting that, as it seems that Plasma 5.20 triggers some problem my NVMe drive (which fluxbox and LXQt do not), so booting from the stick has no problems.

FWIW (again): it seems that the update today might have fixed the problem.  I was able to log in four times (in X11 plasma) with not trouble.  It's hard to say for sure, since the problems seems to be more or less sporadic, but looks promising.
