Wall Changer is an automatic wallpaper changer for GNU/Linux.
You can select images that will be used as wallpapers,
select commands to set wallpaper, wallpaper change time interval.
Program works in GNU/Linux, FreeBSD.
Version: 1.5.3 (last update: 14.07.2020)
Wall Changer may be installed from program package or from software repository.
Package version contains official program release with source code, configuration and build scripts.
Software repositories contains fresh, up to date program code, yet it still may be less stable than package version.
Arch linux package in AUR:
Downloading source code from GIT or Mercurial:
git clone https://git.savannah.nongnu.org/git/wallchanger.git
hg clone https://hg.savannah.nongnu.org/hgweb/wallchanger/
Software repositories does not contain configure and build scripts, you must have autotools installed and run autogen.sh to link appropriate scripts.Compiling program - go to source code directory and type:
./configure make make installAlthough I suggest to configure and compile with more detailed options described below.
./configure CFLAGS="-march=native -O2 -pipe"or more specific:
./configure CC="gcc" CFLAGS="-march=native -O2 -pipe -std=gnu17" --prefix=/usrwith CLANG:
./configure CC="clang" CFLAGS="-march=native -O2 -pipe -std=gnu17" --prefix=/usrIt disables the standard -g option which produces debugging information
CC="gcc" sets the C compiler to gcc, CC="clang" sets the C compiler to clang, -march=native enables all instruction subsets supported by the local machine, -O2 sets the code optimization to level 2, -pipe use pipes rather than temporary files for communication between the various stages of compilation, -std=gnu17 sets the C standard to C17 with GNU extensions. --prefix=/usr installs program in /usr directory instead of /usr/local
If compilation ends without problems, 2 executable files will be created:
wchangerd works in background and changes wallpaper in specified time intervals.
wchangercfg is a configuration window to set wallpaper change time intervals,
images on wallpaper list, the way wallpapers change, etc.
working with the wchangerd daemon:
wchangerd --start Starts the wchangerd daemon wchangerd --stop Stops the wchangerd daemon wchangerd --restart Restarts the wchangerd daemon wchangerd --once Change wallpaper once and exit wchangerd --config Loads configuration from file provided here
The wallpaper change command is selected based on the currently used window manager. Application has default wallpaper change commands for several window managers. Default commands can be changed througn wchangercfg, using Select button. It opens wallpaper command set dialog with list of window managers and commands. After checking and setting commands, especially for Xfce, which has an unusual wallpaper set command, you can use this app with different window managers without changing settings.
Afer changing settings using wchangercfg, wchangerd daemon will load them before next wallpaper change. If you want to load settings before that time, you need to restart wchangerd daemon using wchangerd --restart command.
Default places for configuration file:
(application will look for it in order like on the list below)
~/.config/wchanger/config.json ~/.config/wchanger.json ~/.config/wchanger/wchanger.jsonTo use other than standard config path, use the --config option:
wchangerd --config [FILENAME] wchangercfg --config [FILENAME]
