Kubuntu 15.04 Widget Appearance

[gus_zernial]

Installed Kubuntu 15.04. Minor question about desktop icon/shortcut/widget. Default icon background is translucent/grey. How do I change icon background to transparent/none? Thx, Gus

1) Use a desktop theme with transparent background.

KDE System Settings > Workspace Theme > Desktop Theme

2) Create/edit the theme:

I couldn't find TrustyAir to install, so I installed NoRa, which seems to be transparent (?). Then ls in ~/.local/share/plasma/desktoptheme/NoRa/widgets gives the below. Am I in the right directory? Which file do I edit?

Earlier should be :


1) Use a desktop theme with transparent background.
2) Or create/edit the theme:

Current Theme Elements

...Each theme is stored in a subdirectory with the following file structure

/widgets: generic desktop widget background...

/background.svg: a background image for plasmoids....

Opening the /widgets/background.svgz file in a svg editor (Inkscape)

Editing only the middle - this is only an example.

Saving.

Cleaning the cache: ~/.cache/... Removing the plasma-svgelements and the kcache files.

Changing the desktop theme to the MyBreeze.

The Widget background is transparent.
