Where Does Nitrogen Save Wallpaper?
Nitrogen restores wallpapers from a saved config in home on Linux. The bg-saved file and multi-monitor pattern.
Last updated
Nitrogen keeps one saved file naming the wallpaper per monitor plus the display mode. Setting a background writes that file. Restoring replays it through xwinwrap style calls.
That tiny state design makes moves one copy. Images stay outside the config in picture folders. Multi-monitor setups add numbered sections that map screens by index.
Where Nitrogen stores this, by platform
~/.config/nitrogen/bg-saved.cfg
Saved wallpaper paths and per monitor modes in one file. Images stay in picture folders outside config. Wire nitrogen --restore into autostart for persistent desks.
Frequently asked questions
How do I move Nitrogen settings?
Copy the nitrogen config with Nitrogen quit. Saved paths and per monitor modes travel with it. Image files stay in picture folders, so include those for full moves across machines.
How do I restore wallpaper at login?
Run nitrogen --restore from autostart with the saved config present. Each monitor keeps its own file and mode line. Without the autostart entry the desktop resets on every login.
