Could have a look in
Configure Your Desktop > Workspace Appearance & Behaviour > Workspace Appearance > Desktop Theme
and see if the Glassified theme works
You've also got the Details tab (same area) which allows more customized control
Sorry, what does it mean, Glassified theme works? It is the chosen one for me in all the list (includes panel background item), but there's no transparency on panel.
Strange, PCLOS 2011 installed on my PIII 1.4GHZ computer with working transparency panel. (4,6 KDE I guess) My main PCLOS system (2012) runs KDE 4.8 on better HW, but there's no transparency panel. (It's not so important, but...)
. In your main system, have you enabled the desktop effects ? It's one of changes they made in KDE since 4.8 (I think). You have to enable desktop effects to get that transparent panel. Hit Alt+Shift+F12
to activate, or Configure Your Desktop > Workspace Appearance and Behaviour > Desktop Effect > Check enable desktop effect at startup
I notice in my old hardware activating desktop effects in KDE 4.8 and later version will bring system down to its knee. The system gets very unresponsive
. Previously, in KDE 4.6 the desktop effects run just fine in that hardware (wobbly windows, magic lamp, desktop cube etc). That unresponsiveness leave me no choice but disable desktop effects which make me lose the transparency in panel. Alternative solution I've found work is to use another compositor software, in my case I install compton
and its manager - xcompton-tools
from repo. It's lightweight, only consume RAM around 480 KB Type 'compton' in Synaptic search should bring these two result. There should be two shortcuts after installing: compton-start
. To get transparency, just tinker with Transparency Setting
. In my case, I just check and set Opacity for menus
and Opacity for window titlebar and borders
to 0.85. Hit Save
to save the config.
KDE 4.9.2 + compton compositing ....
