There are several gaps between messages in log you quoted, which one specifically do you mean?

I think the application starts just here 22:42:07 22:42:33 But I'd better do another attempt and check, because I don't remember.

That is not going to work. You connect via ssh and likely forward X11 connection from remote system to local display. But your login session on the remote system has its own session D-Bus instance which knows nothing about the desktop environment on your client. So your GUI application attempts to invoke services on your client desktop via connection to server D-Bus.

To transparently start applications via ssh X11 forwarding one would need to also forward D-Bus connection. While it is possible to forward D-Bus socket (I tested that it works) security implications are not clear (D-Bus can no longer verify the user that makes the request. All requests will appear to come from the client ssh process).

I confess to not know what D-Bus is, except that I see references to it in the logs since several years ago, complaining of this or that, in every computer. Thus I'm not intentionally doing anything about D-bus. The only thing I know is that there was no delay in 15.2, and there is a long delay in 15.3 :-) So if the application can work without dbus, and there is a way to tell the application to not try dbus, I suppose I would be happy. The delay doesn't happen when I run the same command locally. But the keyboard and display is too small for confort, if it can be avoided... - -- Cheers, Carlos E. R.

Here is the delay. Then the application starts and I get all those messages below (and nothing in between):

Service is started by systemd user instance which is not aware of DISPLAY exported by sshd. I tried "systemctl --user import-environment DISPAY" before starting program that triggers xdg-desktop-portal, and that gets rid of "Failed to start Portal service", but I still observe the same 20+ seconds delay before application finally launches.

ok, so that is not the cause.

So if the application can work without dbus, and there is a way to tell the application to not try dbus, I suppose I would be happy.

This is the same as asking an application to not try TCP/IP protocol to work around DNS resolution issues.

Well, maybe I miss something obvious, but AFAIK, when working over ssh dbus doesn't work, yet the application works fine, so why even try?

D-Bus is a communication protocol. It is the de-facto standard today for communication between desktop components. You cannot "tell the application to not try dbus". At most you can tell the application to not attempt to contact service that causes delay. But I do not know how to do it. For a start, I do not know why xdg-portal service is invoked at all - all I have seen so far suggests that it should be opt-in.

So far the only way to eliminate this delay I found was to forward Unix socket from remote client to local user D-Bus socket and tell remote side to use it. But that sounds horribly wrong for multiple reasons.

I suggest you open a bug report to clarify whether this is an upstream issue or caused by the local SUSE patch.

Ok, will do.

...

The delay doesn't happen when I run the same command locally.

Of course it does not. In this case you have a consistent desktop environment where your application runs.

Still, desktop belongs to user "cer" and application is run as root. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)

I confess to not know what D-Bus is, except that I see references to it in the logs since several years ago, complaining of this or that, in every computer. Thus I'm not intentionally doing anything about D-bus. The only thing I know is that there was no delay in 15.2, and there is a long delay in 15.3 :-)

So if the application can work without dbus, and there is a way to tell the application to not try dbus, I suppose I would be happy.

This is the same as asking an application to not try TCP/IP protocol to work around DNS resolution issues.

Well, maybe I miss something obvious, but AFAIK, when working over ssh dbus doesn't work, yet the application works fine, so why even try?

Complain to desktop developers. Linux desktops became rather complex and need much more than just a plain X11 server to work. Apparently nobody is motivated enough to design "desktop application forwarding". Personally when I need GUI I just start VNC. Unfortunately, even that fails because developers are not willing to support more than one graphical session per user ... I wonder if I can start "virtual seat" so that two sessions do not conflict.

:-( I don't want to start whole GUI sessions remotely, just terminals and applications. Can have several terminals from several machines and repeat ops on each. Several GUI sessions is a nightmare. We are going to looe a pro point against windoze :-(

D-Bus is a communication protocol. It is the de-facto standard today for communication between desktop components. You cannot "tell the application to not try dbus". At most you can tell the application to not attempt to contact service that causes delay. But I do not know how to do it. For a start, I do not know why xdg-portal service is invoked at all - all I have seen so far suggests that it should be opt-in.

So far the only way to eliminate this delay I found was to forward Unix socket from remote client to local user D-Bus socket and tell remote side to use it. But that sounds horribly wrong for multiple reasons.

I suggest you open a bug report to clarify whether this is an upstream issue or caused by the local SUSE patch.

Ok, will do.

Please post bug number here.

Yes, yes, will do, but patience, I have several problems dancing around me at the moment...

The delay doesn't happen when I run the same command locally.

Of course it does not. In this case you have a consistent desktop environment where your application runs.

Still, desktop belongs to user "cer" and application is run as root.

How are we supposed to know what you did? You said "I run the same command" and the command was "meld". You did not say "I used su or sudo to run this command as root" which is implied now.

Nonono, I don't use sudo or su (with the problem). I use "ssh -X root@machine", from another machine in same LAN. The laptop is running a local sesion as user cer, obviously, but I don't use it. It is just half a metre away, tiny keyboard and display, so I prefer big display and do maintenance on it via ssh from main computer. Have done that for many years. I simply tried meld locally on that machine for verification: on local session, as cer, do "su -", then run the same meld command as I did via ssh. It is in the bash history.

I can reproduce your issue when ssh into a local host and different user or doing "su - otheruser". In both cases I get the same delay. If you provide exact steps when issue does *not* happen, we could test it.

Ok, on local session and seat (can't copy paste, mail is on another computer): cer@legolas:~> su - legolas:~# su - legolas:~# meld /etc/ssh/sshd_config /etc/ssh/sshd_config No delay, just 2 or 3 seconds, as expected from puny CPU. Typing on main computer, use ssh to Legolas: cer@Telcontar:~> cer@Telcontar:~> ssh -X root@legolas.valinor Last login: Mon Dec 27 20:07:52 2021 from 192.168.1.14 Have a lot of fun... Legolas:~ # meld /etc/chrony.conf /etc/chrony.conf & [1] 11560 Legolas:~ # A long delay. I count to 30 on my mind. Could use a stopwatch to be precise if needed. -- Cheers / Saludos, Carlos E. R.

I still observe the same delay and I do not see how it can be different. I am using Tumbleweed and not meld but another GNOME program. So it could be that GNOME tries to do something more.

meld is not a gnome app, I think. (rpm -qi meld) Summary : Visual diff and merge tool Description : Meld is a visual diff and merge tool. Two or three files can be compared and be edited in place. (The diffs update dynamically). Two or three directories can be compared and file comparisons be launched. The working copy directory from version control systems such as CVS, Subversion, Bazaar-ng and Mercurial can be browsed and viewed. Distribution: openSUSE Leap 15.2 Then, I'm using Leap, not TW, perhaps the feature has not been added here >;-) Something else I noticed, on my old laptop #1: meld suffers the delay on 15.2 (I tried just before upgrading). This is new, I'm certain that meld worked before without delays or I would have noticed. So there is some update that created this delay at some point during the lifetime of 15.2 I know for certain because I always use meld after upgrading from 15.1 to 15.2, say, it is part of the routine. And I have three machines in which I prefer to work remotely, even if they are half a meter away... -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
