Wallpaper plugin

[pwabrahams]

I learned from bugs.kde.org that there is a wallpaper plugin for KDE 4.4 that provides color gradients for the desktop. Is there a way to install that for the current release, 4.3.4?

Re: Wallpaper plugin

Hmm - this bug ? > Bug 194272 - no gradient background possible


The sources are available (FOSS) > http://websvn.kde.org/trunk/KDE/kdeb...lpapers/color/


This is with the Kubuntu 9.10 / KDE 4.3.2 / Qt 4.5.2


Example (you do this at your own risk)


I have installed:
- build-essential
- kdelibs5-dev
- kdebase-workspace-dev
+ lot of others...

Downloading:

svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdebase/workspace/plasma/generic/wallpapers/color

A color/color.cpp
A color/Messages.sh
A color/config.ui
A color/color.h
A color/plasma-wallpaper-color.desktop
A color/CMakeLists.txt
Checked out revision 1073705.

cd to the color directory and addind to the CMakeLists.txt few lines - after that:

CMakeLists.txt

project(plasma-wallpaper-color)

set( CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/cmake/modules )

FIND_PACKAGE(KDE4 REQUIRED)
INCLUDE(KDE4Defaults)
ADD_DEFINITIONS( ${QT_DEFINITIONS} ${KDE4_DEFINITIONS} )

INCLUDE_DIRECTORIES( 
  ${KDE4_INCLUDES} 
)

set(color_SRCS
  color.cpp
)
kde4_add_ui_files(color_SRCS config.ui)

kde4_add_plugin(plasma_wallpaper_color ${color_SRCS})
target_link_libraries(plasma_wallpaper_color ${KDE4_PLASMA_LIBS} ${KDE4_KIO_LIBS})

install(TARGETS plasma_wallpaper_color DESTINATION ${PLUGIN_INSTALL_DIR})
install(FILES plasma-wallpaper-color.desktop DESTINATION ${SERVICES_INSTALL_DIR})

Making a build dir:

mkdir -p builddir

Compiling:

cd builddir && cmake .. -DCMAKE_INSTALL_PREFIX=/usr

make

After that the /color/builddir/lib/ has: "plasma_wallpaper_color.so"

With the KDE 4.3 the plasma_wallpaper_color.so is coming from the:

apt-file search plasma_wallpaper_color.so

kdebase-workspace-bin: /usr/lib/kde4/plasma_wallpaper_color.so
kdebase-workspace-dbg: /usr/lib/debug/usr/lib/kde4/plasma_wallpaper_color.so

Backing up the original /usr/lib/kde4/plasma_wallpaper_color.so.

Copying the /color/builddir/lib/plasma_wallpaper_color.so to the /usr/lib/kde4/.

Log out - log in

Right clicking the desktop > Desktop settings

Seems to work...

Re: Wallpaper plugin

The old and new color (Color & Color2 ) can live in the same system.

Wrapping the new to the .deb > PPA >> PPA for Rog131 >>> Package name contains: plasma-wallpaper.


After installation and plasma restart (log out log in) there are Color and Color2:

Re: Wallpaper plugin

way to answer that question Rog

[pwabrahams]

Where is the color directory?

I tried to follow the recipe but only got as far as the svn step. I wasn't able to install the modules listed earlier because synaptic couldn't find them. What is the path to the color directory you refer to -- the one containing CMakeLists.txt?

And yes -- I was looking at Bug 194272.

You could just install the package rog packaged into his ppa repository (the link is in his last post) to avoid having to compile it yourself.

Adding the repository to Synaptic

I tried adding the repository to the Synaptic repository list by prefixing the URL with deb. That didn't work -- Synaptic rejected it. So I tried also adding karmic new at the end of the line -- just a guess. Synaptic accepted that but then, after a reload, couldn't load anything from that repository.

So how do I convert that URL to something that Synaptic will accept as a repository and process correctly?

The simplest (and recommended) way to add the repository (if you have package 'python-software-properties' installed), is to run:

sudo add-apt-repository ppa:samrog131

[pwabrahams]

Added repository -- then what?

I added the repository as advised, successfully. I then tried:

apt-get install rog

but then got the message "couldn't find package rog". What am I missing?

Re: Wallpaper plugin

The correct package name is: plasma-wallpaper-color2

[pwabrahams]

apt-get install

I tried

pwa@Lepiota:~$ sudo apt-get install plasma-wallpaper-color2
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package plasma-wallpaper-color2

Hmmm.

Re: Wallpaper plugin

After making any changes to repository lists, you have to run apt-get update to refresh the package cache. If you don't, you won't have pulled in the package information for the added repository(ies).

Solved!

Yes, that was the last missing piece of the puzzle. I've installed color2 and used it. Great!!!

Thanks.
