[SDDM] Avoid suspend screen

[Angel Docampo]

I did noticed that if I put a background image, this issue doesn't happen. Even more, I also noticed that configuring /usr/share/sddm/themes/breeze/theme.conf as well as /usr/share/sddm/themes/breeze/theme.conf.user but putting a background image, when sddm returns from suspend, it shows the background image specified, but If I put the same video I put on them.conf.user or no config at all, it shows the standard blue breeze color.

So my config is:
/usr/share/sddm/themes/breeze/theme.conf.user
[General]
background=/opt/IMI/fondos/Barcelona.mp4

If I put a "fallback" background image on /usr/share/sddm/themes/breeze/theme.conf like
[General]
background=/opt/IMI/fondos/Barcelona.png

If there is nothing on background direcitve, so a plain color appears.

I did also notice that there are a qml file named Background.qml, which only considers two options: image and color.

    states: [
        State {
            name: "imageBackground"
            when: sceneBackgroundType == "image"
            PropertyChanges {
                target: sceneColorBackground
                visible: false
            }
            PropertyChanges {
                target: sceneImageBackground
                visible: true
            }
        },
        State {
            name: "colorBackground"
            when: sceneBackgroundType != "image"
            PropertyChanges {
                target: sceneColorBackground
                visible: true
            }

I do not know if it is related somehow, but perhaps it should consider sceneVideoBackground... just an idea.

What do you think?

Ok, so I'm going to post it on sddm's github to let the devs know the issue and perhaps some user has faced it also...

I know is a rare condition, when someone turns on the computer, immediatly logs on, but on enterprise scenarios is more frequent that people turns on the computer and go for a morning coffee and chat with the workmates (you know...) before they login, or on shared computers, SDDM can suspend between the time when a worker logs off and the next worker logs on.

Hi list,

I'm having a little issue with SDDM. The end client loves the video background feature, and they made me change the corporate background for a corporate video. I've set the video as explained here without problems https://forum.kde.org/viewtopic.php?f=289&t=131783&p=364567#p364567 I also set the default lock screen on Plasma to set the same video.

So far so good.

But I detected that If I let the system suspend the screen and turn of the monitor, when I move the mouse and the screen turns up, then, the default blue breeze screen appears instead the video. This issue only occurs in SDDM (not in the lock screen).

Did you guys experienced this behaviour?

In other order of things, I do not know if this issue should be posted on github rather than here, because is not an *enterprise* related issue.



Hi Angel,
It seems like it would be an issue in SDDM anyway and its developers
need to know. I don't think we have different code on SDDM and lock
screen regarding video display (David correct me if I'm wrong), so if
anything upstream SDDM should know about the problem.

On the other hand this doesn't mean that it's not an issue in our user
experience that needs to be figured out. I doubt many people have
tested video on the background + suspending SDDM... :)
