Status icon is broken in KDE Plasma 5

[tankmissile]

When starting variety in KDE Plasma, clicking the status bar icon does not bring up the menu. The icon also looks blurry (probably incorrect sizing or theme).

KDE Plasma now has a D-Bus message system that can be accessed through the qdbus command. The wallpaper can be changed using the command below. However, it only works when widgets are unlocked. There's some kind of security vulnerability if widgets are locked.

qdbus org.kde.plasmashell /PlasmaShell org.kde.PlasmaShell.evaluateScript "
var allDesktops = desktops();
for (i=0; i < allDesktops.length; i++) {
    d = allDesktops[i];
    d.wallpaperPlugin = 'org.kde.image';
    d.currentConfigGroup = Array('Wallpaper', 'org.kde.image', 'General');
    d.writeConfig('Image', 'file://"$WP"')
}
"

When the set_wallpaper script is generated, it can not be edited due too invalid characters. I was able to scrub the script clean myself, but it's still a nuisance too new users.

Hi,

The invalid characters error should be fixed by the latest revision (590, https://bazaar.launchpad.net/~variety/variety/trunk/revision/590).

Regarding the Variety indicator, I can't get it to display at all in Plasma 5.8; nor does wallpaper changing appear to work. Changing the wallpaper via qdbus does seem like the right solution, though it's a new feature that's only in Plasma 5.7 and above AFAIK: https://github.com/KDE/plasma-workspace/commit/903cbfd7e267a4812a6ec222eb7e1b5dd775686f

In the future, please consider reporting multiple bugs instead of combining several different issues into one thread, as it makes bug management a lot easier for us :)

Apologies for not splitting up these issues. I thought they were insignificant enough to be combined into one, but from a development standpoint I see your point. Anyway, I have an update on the status bar issue. It can be solved by installing libappindicator-gtk3 (if you use Arch Linux).

"Hi Peter,

I'm just writing to let you know that last year KDE finally came
through. It is now possible to change the wallpaper via dbus, including
via the command line. More details are in the KDE bug which is linked
from your web page, but this is the shell command to change the
wallpaper on all desktops:

qdbus org.kde.plasmashell /PlasmaShell
org.kde.PlasmaShell.evaluateScript 'var allDesktops = desktops();print
(allDesktops);for (i=0;i<allDesktops.length;i++) {d =
allDesktops[i];d.wallpaperPlugin = "org.kde.image";d.currentConfigGroup
= Array("Wallpaper", "org.kde.image", "General");d.writeConfig("Image",
"file://'"$FILE"'")}'

Be well,

Ian Turner"

I've committed the qdbus wallpaper changing code into trunk: https://bazaar.launchpad.net/~variety/variety/trunk/revision/607

The status icon problems still need investigation.

Thanks, James.

Cannot test on KDE - is qdbus fix fully confirmed working? Are KDE users now supposed to do anything special, or things just work out of the box?

If things just work, there is a related change to remove the KDE-specific instructions from the welcome screens, and there was something in Tips&tricks about KDE too. Also, I can update the instructions on the website to reflect the new situation.

On Plasma 5.7 and later, wallpaper changing should work out of the box.
This is what I've experienced anyhow. In one of the 0.6.6 commits I removed
the KDE 4 tip, but I haven't looked at the welcome screen.

Status icon is working for me again in plasmashell 5.13.x and Ayatana indicators 0.5.3
