 Posted: Sat Jun 03, 2023 5:21 pm Post subject: 25 second delay in recent update |
 |
|
Not sure what package update happened recently, but now a lot of applications have a 25 second delay before anything happens. This is happening on two systemd/gnome/xfce4 machines but I'm using xfce4 despite gnome is installed.
Pulling up firefox, eog, gnome-disks, epiphany, evince, and others take 25 seconds before the window pops up. Another thing is while Evolution comes up right away, it takes 25 seconds before I can read any mail.
There are programs that don't incur delays and work fine: pavucontrol, gnome-mines, gnome-terminal, and many more does not incur the 25 second delay.
I'm not sure what it's stopping on, it does not appear to be network related, anyone happen to know what could cause this 25 second delay? (This is exactly 25 second timeout on poll() according to strace...)
My guess is actually a dbus or local socket but can't put my finger on it... I think it's also specific to only a few specific GUI/desktop applications, I don't see it in CLI applications.
--- added more programs that exhibit this behavior and ones that do not ---

Launch apps in a terminal and see what might be happening. If a verbose option is available, use it.

Afaik recent (rare) cases of this happening were related to attempts to resolve the system's hostname timing out and could be resolved by adding it to /etc/hosts.
Not that I looked closely at this, and not sure why it started happening now. |

eog and gnome-disks I can readily reproduce, alas no diagnostic output... firefox works fine if I have it running and it forks new windows but if all windows are closed it invokes the delay.
I really don't think it's a hostname issue, I run a caching nameserver and have my caching+soa nameserver resolve all my local hostnames as I do use it to simplify operations. Also what's weird is the sole difference is the 800+ packages that were merged...
I didn't compile with debug symbols yet but the backtrace library stack appears to be libgio libgobject libhandy libgobject libhandy libgobject libgio libglib poll() for gnome-disks and is very similar for eog.
The interesting function name is g_dbus_proxy_new_for_bus_sync - but no other debug symbols or call params to discern the issue. I might have to build full debug symbols into glib to see what's going on...
------------
FSCK
Has something to do with Gnome. When I'm in Gnome it works fine. Just have a problem in xfce4. Perhaps something to do with tumbler?
Also I am using lightdm so I don't think I'm mucking with xinitrc.

If this is a D-Bus-related timeout, it might be easier to run dbus-monitor on the per-login session message bus (the default).

looks like this is the last dbus access before the hang:
| Code: | method return time=1685894384.549181 sender=org.freedesktop.DBus -> destination=:1.169 serial=19 reply_serial=18
method call time=1685894384.549184 sender=:1.169 -> destination=org.freedesktop.DBus serial=19 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=StartServiceByName
string "org.freedesktop.portal.Desktop"
uint32 0 |
and it when the window pops up 25 seconds later:
| Code: | method call time=1685894409.574445 sender=:1.169 -> destination=org.freedesktop.DBus serial=20 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=RemoveMatch
string "type='signal',sender='org.freedesktop.DBus',interface='org.freedesktop.DBus',member='NameOwnerChanged',path='/org/freedesktop/DBus',arg0='org.freedesktop.portal.Desktop'"
method return time=1685894409.574461 sender=org.freedesktop.DBus -> destination=:1.169 serial=20 reply_serial=20 |
Now I'm not sure what service it's trying to start here but there was never a reply_serial=19 ... so indeed there was some timeout from a started service.
I said tumbler earlier as i recalled some issue while it was installing but forgot what the issue was. need something to jog my memory...

It looks like xdg-desktop-portal is not running, fails to run, or something like that. org.freedesktop.portal.Desktop is that program's well-known bus name.

Translation needed?
| Code: | $ xdg-desktop-portal
bash: xdg-desktop-portal: command not found |

Some application of yours seems to want (perhaps since your last update?) to 'talk' over D-Bus to a program named xdg-desktop-portal. Provided on Gentoo by the sys-apps/xdg-desktop-portal package. The program isn't there, or maybe it is but is failing to run.

Ah.
The package is installed (binary is in /usr/libexec) and it appears that there's also a gnome version hence I don't see the same issue in gnome.
Now the question is why is it failing to run ...
Should there be a /usr/share/xdg-desktop-portal/portals specific to the non gnome version... is the gtk.portal file the generic one?

Any messages from dbus-daemon in the logs?

sys-apps/xdg-desktop-portal-gtk is a generic GTK backend, and sys-apps/xdg-desktop-portal-gnome, a GNOME backend (that requires xdg-desktop-portal-gtk).

Ack. Now how to resurrect this dead target...

Okay I have a hack solution that seems to work: I copied the service files for xdg-desktop-portal-*service to /etc/systemd/user and changed the target requirements from graphical-session.target to just graphical.target ... so far this is working fine for xfce4 and the delay is gone, but might break other things.
The problem seems to be that gnome actually reaches graphical-session.target but xfce4 does not. I'm using gdm on one of the two boxes and lightdm on the other. Ultimately this is a systemd issue it seems, that affects just xfce4.
What would be a better, more generalized solution?

at least I'm not out of my mind that I did something to cause it!
Well, other than not using Gnome with xdg-desktop-portal!

It isn't necessary to use LightDM with xfce. Any display manager can be used, or none.

I use BSPWM, and I added this line to .xinitrc file to get gvfs to work with thunar:
ck-launch-session dbus-launch thunar --daemon &
I believe this fixed the 20 second delay for me.
I know this is an old post, but I've had trouble finding a solution to using xdg-desktop-portal with thunar.
So, I hope this helps the next guy. |
