Change windows desktop background for day and night (Ubuntu, GNU/Linux)
Having a bright, blue wallpaper for day use and a darker, reddish wallpaper for evening/night is useful stay in synch with the real time of day. So, i wanted my windows xp machine automatically switch to the day wallpaper from 7-20 and to night from 20-7 hours. The following batch script does this, without any add-on software. To use, copy-paste the file and store it to your scripts directory (e:\etc in my case).
Advantages:
- No additional software (apart from the script) has to be installed
- No additional load on the computer by a desktop switcher, except from the tasks that you define yourself
Notes: directly use a jpg file as a windows wallpaper (the settings dialog creates a bmp file behind your back!).
- Configuration is by changing the set … variable at the top of the file
- Test by calling the batchfile
- To automate the wallpaper switch:
- make a link in the windows autostart folder
- add an hourly task to the task manager (or even cleaner, two tasks at the switch times (7:00 and 20:00)
- changedesktop.sh
#!/bin/bash # Change desktop background image depending on the time of day # Configuration: Change hourse in the case statements, and the images to load as background # # load variables for gconftool. These have to be written to Xdbus during login . $HOME/.config/Xdbus HOUR=$(date +%H) gconftool=/usr/bin/gconftool case "$HOUR" in 06|07) $gconftool -t string -s /desktop/gnome/background/picture_filename ~/Bilder/DSC_0373.JPG ;; 08|09|10|11|12|13|14|15|16) $gconftool -t string -s /desktop/gnome/background/picture_filename ~/Bilder/DSC_1025.JPG ;; 17|18|19 ) $gconftool -t string -s /desktop/gnome/background/picture_filename ~/Bilder/DSC_0959.JPG ;; *) $gconftool -t string -s /desktop/gnome/background/picture_filename ~/Bilder/DSC_0776.JPG ;; esac
