DualHead Watchdog v1.0 Released

Posted at — Feb 16, 2013

DualHead Watchdog is a Linux desktop app which runs commands or scripts after display settings are changed.

It is especially usefull for users who prefer window managers to those huge desktop environments. For these people, wallpapers often cannot be ajusted automatically when the screen size is changed or dual-head display is started. With this app, people can run custom commands to reset the background image when the display settings are changed.

For example, I use i3wm in my daily life and I use dual-head display, my laptop has a screen resolution as 1366x768 and my outer display is 1920x1080. So when I start the dual-head display, the background image in the outer display is tiled with 1366x768 images. So I put the following commandline into this app:

feh --bg-scale ~/.wallpaper

“~/.wallpaper” is a soft link to my wallpaper. So when dual-head display is started, this command will be called and my wallpaper will be reset to fit the new screen size.

More than that, users can make this app do everything when display settings are changed. At the moment, there will be a ‘monitors-changed’ and a ‘size-changed’ event, users can specify which event to listen to for each command.
