Ubuntu – Panel Transparency in KDE Plasma

kdekubuntupanelplasma-5themes

Okay, So using Kubuntu/KDE Plasma 5.13, I can obviously change colors, add panels and do a lot of personalization stuff that I really like. But what I am really interested in is changing the transparency/translucency of the panel. I can't do it via settings/(any other GUI stuff) obviously. Is there any kind of tweak (editing configuration files, etc.), coz I know it's possible as they create translucent/transparent themes. How is this done?

Best Answer

From what I know, you cannot edit any config file to do so, but rather have to change the background image of the panel to something that is transparent (i.e. an SVG file that is transparent)

Short answer

Changing the /usr/share/kde4/services/kded/device_automounter.desktop line from
```
> X-KDE-Kded-phase=1
```
to:
```
> X-KDE-Kded-phase=0
```
Starting 'Removable Device Automounter' from the Service Manager using
```
kcmshell4 kcmkded
```
Picking the right options from the KDE 'Removable Devices module usinc
```
kcmshell4 device_automounter_kcm
```

Explanation

KDE System Settings (5)

The Kubuntu 15.04 is using KDE System Settings that can show KDE Control Modules (kcm) for the KF5/Plasma5. The removable devices kcm is from the KDE4. You could launch the KDE Control Modules from the command line, i.e. the following command will launch the module:

kcmshell4 device_automounter_kcm

KDE Removable device windows

Daemon must be running

The 'Removable Device Automounter' Service, another KDE(4) control module, needs to be running. Check with:

$ kcmshell4 --list | grep kcmkded
kcmkded                    - KDE Services Configuration

As default the Removable Device Automounter is not running by default, open the windows and start the serice:

kcmshell4 kcmkded

KDE service manager windows

Configure KDE Daemon start-up

the KDE(4) Daemon (kded) desktop files are in /usr/share/kde4/services/kded/ ;
the device_automounter.desktop has line

X-KDE-Kded-phase=1

From HOWTO Make KDED Modules:

The exact way autoloading works is controlled by X-KDE-Kded-phase=, which may be 0, 1 or 2 (the default). Kded phase 0 means the module is always loaded by kded, even outside of KDE session. It should used only by kded modules which must be always running. Kded phase 1 modules are loaded right after kded startup, but only during KDE startup, i.e. it is for modules that are always needed by the KDE session. Phase 2 modules will be loaded later.

Maybe the KF5 KDE is not detected as proper KDE?

We need to change the device_automounter.desktop line to:

> X-KDE-Kded-phase=0

editing device_automounter.desktop

The Removable Device Automounter service will be running after a reboot.

I had same issue but I got it solved when I changed rendering backend to XRender for my Nvidia card.
