Added the 'journalctl -b 0' log as suggested?

The timeout is probably related to network mounts, and/or your theme:

Απρ 24 14:07:26 vassilis-ms-7680 gnome-shell[2564]: JS ERROR: TypeError: iconTheme is null
                                                       _getWorkingIconName@/<email address hidden>/locations.js:150:21
                                                       _onMountAdded@/<email address hidden>/locations.js:225:35
                                                       DashToDock_Removables/<@/<email address hidden>/locations.js:116:22

I can confirm the bug. Happens also to me. Have attached my journalctl.

Status changed to 'Confirmed' because the bug affects multiple users.

What icon theme do you use?

Do you have remote share or disks mounted? if so could you try if unmounting them makes a difference?

I have no disks mounted by default. And I use the default theme. I just created a new user for testing and it happens for that one too as soon as you switch to the wayland-session.

so it's happening in wayland only and not xorg?

Could you include the log of
$ gio mount -l

It happens only for wayland. Just tried out again with the tester account. Attached is the output of gio and journalctl for that account. As you can see gio reports two SSD, a HDD, and a DVD but not other mount.

Confirming this issue on an 19.10 to 20.04 upgrade (originally 18.04). Problem persisted after a dconf reset. Problem also oberserved on a fresh 20.04 with old profile. Problem also observed on fresh install in virtualbox with a fresh user profile. All were minimal installs if that matters which I highly doubt. Reproducible by running

'gsettings set org.gnome.shell.extensions.dash-to-dock show-mounts false'

and restarting gnome. Toggling it back to 'true' and restarting gnome clears the issue for me.

Running X11.

I can confirm that after a

'gsettings set org.gnome.shell.extensions.dash-to-dock show-mounts false'

the icons appear immediately after login. Thanx Nicolas!

Status changed to 'Confirmed' because the bug affects multiple users.

I also confirm that roting 'gsettings set org.gnome.shell.extensions.dash-to-dock show-mounts false' from false to true and back fixes this issue.

I also have the problem, that icons in the dock have a delay of 25 seconds between program start and dock update.

This is a fresh install of 20.04 LTS on a clean laptop with a wiped hard disk.

schorsch@jbook:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04 LTS
Release: 20.04
Codename: focal

schorsch@jbook:~$ uname -a
Linux jbook 5.4.0-29-generic #33-Ubuntu SMP Wed Apr 29 14:32:27 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

The only thing I did after the new installation was installing the dash-to-panel Gnome extension. Once, I deactivated that extension and the Ubuntu Dock showed again, I noticed the delay. However, I cannot say for sure if the delay has been there from the beginning.

I completely removed the dash-to-panel extension using apt, but the Ubuntu Dock delay is still there.

Also, the 'gsettings set org.gnome.shell.extensions.dash-to-dock show-mounts false' thing did NOT work in my case. The dock still has the delay.

I can confirm this bug an completely vanilla 20.04 and 20.10 installs on two completely different machines.

Long startup for icons to appear at boot, non favourite apps will appear with delay and moving apps will also have a big delay to appear in the new order.

To be fair, this should probably be prioritized higher.
a) the specific configuration is more common than you might think
b) there is a fundamental problem with this extension representing itself as a whole slew of different issues.

I confirm this issue, too. I have a disk mounted automatically via /etc/fstab when booting, and the disk icon shows up on dock by default. After this, the dock loads very slowly. After I remove the entry from /etc/fstab, the issue is gone.

Using Ubuntu 20.04, I have a disk mounted automatically via /etc/fstab when booting. I tried with show-mounts enabled and disabled, and both are delayed.

OK, thanks. I have reopened your bug 1900907.

Thanks, I will add some more info in bug #1900907.

Worth to say that in my case, even 'gsettings set org.gnome.shell.extensions.dash-to-dock show-mounts false' doesn't fix it. Also clicking on dotted button "Show aplications" doesn't do anything until I click on Activities in top bar once. Ubuntu 20.04 LTS (no custom extensions, kernel 5.11)

Petr, in that case this is the wrong bug for you and you should open a new bug.

Bonjour,
Si ca peux aider, sous Wayland je l'ai résolut avec:
# sudo apt remove --purge hydrapaper
