I saw the same behavior as Sebastian in linux mint 20.2. Tried with apps "flameshot" and "obs-studio" - both behave
QT apps are stuck about 25 seconds. Strace exactly like Sebastian's: connect(12, {sa_family=AF_UNIX, sun_path="/run/user/1000/bus"}, 110) = 0 … yada yada … poll([{fd=14, events=POLLIN}], 1, 25000 … 25 second timeout … (something in strace about … Timeout) <program runs normally after timeout> I was helped by (https://www.scivision.dev/disable-gnome-keyring-ssh-agent/) Edit /etc/xdg/autostart/gnome-keyring-ssh.desktop to include the line: X-GNOME-Autostart-enabled=false and restart. Not just logout, full restart. Now all same apps start in 0 secs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852016 Title: Applications delayed on launch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/1852016/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
