Description of problem:

I find this first time in bug·34183
But this happend to other applications 

libreoffice 

(soffice:2580): dbind-WARNING **: 20:01:32.231: Couldn't connect to accessibility bus: Failed to connect to socket /root/.cache/at-spi/bus_0: Permiso denegado

mousepad 

(mousepad:64149): dbind-WARNING **: 20:30:13.287: Couldn't connect to accessibility bus: Failed to connect to socket /root/.cache/at-spi/bus_0: Permiso denegado

The message goes away if I add before the application

NO_AT_BRIDGE=1

Jose

Please, to summarise your system, post the O/P of:
 $ inxi -MSG

Is it worth looking in the system journal before these messages appear?

You cite libreoffice & mousepad, but say "this happend to other applications". Does this mean that the problem is widespread?

If you can find the Upgrade log, which is normally...
As root, look at:
 # ls -l /root/drakx/
for the files(s):
 /root/drakx/report.bug         [uncompressed]
 /root/drakx/report.bug.xz      [compressed]
but I am unsure if they apply to a Cauldron upgrade. If the dates correspond:

If only the compressed one (xz) is present, attach that to this bug.
If both are present with the same (upgrade) date, attach the compressed (xz) one.
If only the uncompressed file is present, or if both are present and the compressed (xz) file is older than uncompressed one, do:
 # xz /root/drakx/report.bug
which will create the corresponding compressed one - to attach to this bug.

firefox not produce the message but gimp, filezilla, neochat, l3afpad does
Not have much time to test all the applications, even if are less than in
my real mageia 9 installation

As I migrate by urpmi not recent information
Comment 3 katnatek 2025-05-10 03:57:48 CEST
I star to think is caused by lxdm with sddm not happen
I will be back to use lxdm to test, if not some update could have fixed this
Comment 4 katnatek 2025-05-10 04:08:26 CEST
Well lxdm is part of the equation, but enabling AT-SPDI-D-Bus bus at desktop start
is a workaround/solution

Leaving this with you for now, Jose. You are the best for chasing it.

Comment 6 Lewis Smith 2025-05-14 20:53:46 CEST
A clarification please:
comment 0 says "The message goes away if I add before the application
NO_AT_BRIDGE=1" which is tedious;
and comment 4 says "enabling AT-SPDI-D-Bus bus at desktop start
is a workaround/solution" which looks simpler;

Do you need both? Or either?

Also, does the error message "dbind-WARNING **: 20:30:13.287: Couldn't connect to accessibility bus: Failed to connect to socket /root/.cache/at-spi/bus_0: Permiso denegado" have any negative effect on the application - like preventing it from starting? Or does the application continue anyway?

Both things are true, the NO_AT_BRIDGE=1 is a solution I find in web searches
And Enable AT-SPDI-D-Bus bus at desktop start in the Lxde configuration tool is
what I find by testing

All the applications that produce the message starts, but I not test if exists some nasty effect , but quite sure is better to not have any potential issue.
Comment 8 Lewis Smith 2025-05-18 21:25:51 CEST
Unsure where to push this. Is it a basesystem issue?
Assigning initially to NicolasS who seems to be the main packager for LXDE. But do please re-assign it to whoever you think is the best person; you are a better judge than me.
