I also found that.

"[Boomaga GUI] WARNING: Can't read DBUS session directory /var/spool/cups/tmp/.dbus/session-bus"
I was looking for printing of brochures. (devuan chimaera, printer samsung C410W).
Boomaga is in the standard repositories what implies it is working anyway.
All fine until printing from boomaga to standard printer C410W. Nothing happens. No error messages, nothing in C410W queue.
Any ideas?
Tried nouveau. Horrible tearing.
Got rid of all nvidia & nouveau stuff by purge.
Manually installed nvidia 470 driver from nvidia.de download. No remarkable tearing even without composite option.
No freeze overnight.
Now I'll observe it some more days before setting to solved.
Unfortunately another freeze occured.
Next trial will be nouveau driver.
Look at my post from 2021-11-02 07:25:11. Those were all logs with entries around freezing time.
With XFCE no freeze occured within 31 hours. I'll keep on observing but set it for now to [SOLVED]. I hope I won't have to change that.
Update: No freeze with XFCE4 yet.
Nouveau is the next trial on my list. At present I'm testing xfce desktop environment (don't ask me why, there's no logical reason for it).
Is there a way to display all system or Xorg actions? Just to remind that: the sound ist still working, programs continue, cronjobs are started ... only the display shows the content of freeze time and mouse / keyboard input to the session does not work, but to sysrq does.
Where could "somewhere" be? It's an xfce-background.
Bad news: The system froze again tonight around 4:22 h. So it was not SLIM.

/var/log/daemon.log, auth.log, Xorg.0.log: no events around 4:22h.
GPU temperature was 39°C at freeze.
So, that's all information I could get.
Any ideas?
What is desktop-base?
Seems to be vice versa. The jumping fat rat replaces another previously loaded background within some hundred ms. Looks like blending.
Only a minor problem:
After changing from slim to lightdm the greeter backgrond is an xfce one. I don't know where it comes from, because
/etc/lightdm/lightdm.conf
refers to
greeter-session=lightdm-gtk-greeterand the
/etc/lightdm/lightdm-gtk-greeter.conf
points to
background = /usr/share/images/desktop-base/greeter-wide-large.pngand that is no jumping fat rat.
Also the charset ist not the one in /etc/lightdm/lightdm-gtk-greeter.conf .
So obviously another config file is used, but which?
Update: After changing to lightdm no freeze overnight. I'll look at it some more days, then set it (hopefully) to solved.
I'll give it a try. But it would not explain why the freeze doesn't happen in ASCII but in it's upgrade to Beowulf - Chimaera.
At freezing time my CPU usage is low, same as memory (usually it happens while recording something overnight). Recording is continued, even new recordings are started after freeze. So I could run a logging program on the system itself and read it from another installation on the same computer.
Caps/Num/Scroll Lock keys are not working. I wonder why Magic SysRQ keys do.
Once the mouse pointer was still working on one of the monitors, but with no response to mouse keystrokes.
It seems to be an xorg crash cutting off all I/O devices.
No, it's a AMD Ryzen 7 3700X.
Ctrl+Alt+F1 doesn't work.
No SSH trial yet.
Also slim/mate.
What 100% do you mean?
Display, mouse and keyboard freeze after different working time with chimaera on a Ryzen 7 / Nvidia GTX 1650 / 2 monitor well-cooled tower computer. Low and not increasing system resources' consumption and temperature before freeze. Programs as video recording and sound of video from tv card are still working. No response to any keystrokes (including runlevels) except Magic SysRQ.
None of it with ascii on the same computer, but the same after upgrade from that ascii.
Inactivation of suspend, screen saver and dpms were NO solution.
I found similar freeze reports caused by FullCompositionPipeline activation in the nvidia settings. But without this setting there's an annoying tearing of videos.
Tonight I'll try without FullCompositionPipeline.
I know, there's a lot of information missing, but hope, someone has had the problem too and solved it.
