Ubuntu installation creates errors and does not create makefile

[Sharpnesse]

Hello there,

Apologies if this is due to my own ineptitude - I'm still very new to Linux.

I'm trying to install the script on Ubuntu, and it's all alright up until the cmake command. The output I get in the terminal is below...

cmake .. -DCMAKE_BUILD_TYPE=Release \
>     -DCMAKE_INSTALL_PREFIX=/usr \

After this, the make command will not run because it doesn't find a valid makefile. I'm unsure as to how to proceed - sorry again if this is my own fault!

I think you need to install libkf5kio-dev.

Thanks very much - I've now got it installed, but whenever I activate the plugin it just gives me a black screen. There is no 'add wallpaper' option in the plugin configuration to add any extras, either - it's just the selection box and that's all.

Rebooting hasn't worked, neither has removing and reinstalling the plugin.

Apologies again if it's something that's my fault!

Could you please run plasmashell --replace from command line and post the output here?

It goes on for a long time and keeps on giving more dialogs when using anything or mousing over things - not sure if this is supposed to happen.

This is a clean install of Ubuntu, all I've done is install KDE and remove GNOME afterwards once I got used to KDE.

Alright, this seems to be the reason why you see the black screen. Have you installed qml-module-qtpositioning?

[Sharpnesse]

It works now - thanks so much! What do you think the reason might be that it wasn't installed? Is it possible the prerequisite code for Ubuntu isn't quite right for my version (19.10)?

[HaukeW]

Had the same problem, installing qml-module-qtpositioning fixed it. Thanks, @zzag !
