Due to the very nice integration with the rest of the desktop, I am
using the Breeze theme for SDDM (created by David Edmundson). It looks
way better than the default theme of SDDM, but it has one very big
disadvantage. When the Breeze theme is active, it takes about 1,5 minute
for SDDM to show its login screen. (Measured with systemd-analyze
blame). Using the default theme for SDDM (Maui), then it only takes a
fraction of a second and systemd-analyze blame doesn't even show a line
for it.

The only difference that I notice is that is feels that it takes longer
for plasma to startup when using the Maui theme, then with the Breeze
theme. However these few seconds still doesn't justify the 1,5 minutes
startup for SDDM.

Reproducible: Always

wow. That's pretty extreme

A delay that big must be a DBus timeout (or rather 3 sequential DBus
timeouts).

We end up querying solid for battery status which does go via an
activated kded; so potentially that's where we block.

Can you:
 - confirm what version you are using.
 - tell me where you get your RPMs from
 - check the log files from SDDM (journalctl -u sddm)

Hi David,

The SDDM version that I am using is from git master and we are building
it on openSUSE Build Service. I am part of the openSUSE KDE Community
team and we are currently testing SDDM to see if we could make the same
switch as Fedora from KDM to SDDM.  I am using it in connection with a
Frameworks/Plasma-next desktop.

SDDM on openSUSE is started through the generic display-manager service.
There are indications that we should switch to using separate services
for each display-manager, but this has not yet done, so you might see
display-manager in the journal logs.

Running systemd-analyze blame delivers (top x lines) the following output: 
    1min 30.078s display-manager.service
           560ms ModemManager.service
           536ms systemd-tmpfiles-setup.service
           500ms systemd-logind.service
           499ms firewalld.service
           447ms postfix.service
           429ms plymouth-read-write.service
           214ms mnt-windows.mount
           159ms NetworkManager.service
            67ms lvm2-activation-net.service
            58ms systemd-fsck at dev-disk-by\x2duuid-a15e9da3\x2d0009\x2d4847\x2d978d\x2d34b3de059089.service
            42ms alsa-restore.service
            40ms avahi-daemon.service

So I am not sure if the 1min 30secs is really the time required by SDDM
or that it just indicates that a total boot time of 1 min is reached and
that 30 secs is used for the display-manager.

I have attached two journals (one with the maldives theme active and the
other with the breeze theme). These are the full startup journals of the
current session. I didn't filter them to prevent loosing information.

Hi Kai,

I hope your didn't revert your patch because of this bug report.  I am
running the latest version from git, but still the same issue. So the
revert didn't bring any relief in the startup time of SDDM

@ Raymond

Starting with Plasma 5.5.4 you can select not to have a start screen
(with progress-bar) at all

System-Settings -> Desktop-Appearance -> Start-Screen (select)

Does this speed up your boot?
