NAME
xsnow - Snow and Santa on your desktop
SYNOPSIS
xsnow [/OPTION/]…
DESCRIPTION
Xsnow shows an animation of Santa and snow on your desktop. Xsnow can also run in one or more windows, see options -xwininfo, -id . (These options only work satisfactorily in an X11 environment.) Xsnow depends on an X11 environment. This is forced by setting the environment variable GDK_BACKEND=x11 before initializing the GTK. Hopefully, this will ensure that xsnow also runs in a Wayland environment for some time.
If xsnow is misbehaving, try to remove the file $HOME/.xsnowrc.
“General options:
Below:
<n> denotes an unsigned decimal (e.g 123) or octal (e.g. 017) or hex
(e.g. 0x50009) number.
<c> denotes a string like “red” or “#123456”.
<f> denotes a file name, like “/home/rick/Pictures/background.jpg”.

“FILES
- $HOME/.xsnowrc
- Settings are read from and written to this file.
See flags -noconfig and -defaults how to influence this behaviour.
NOTE: the following settings are not read or written:
-above -defaults -desktop -fullscreen -noconfig -id
-nomenu -stopafter -xwininfo -display -noisy -checkgtk - $HOME/xsnow/pixmaps/tree.xpm
- If present, xsnow will try this file
for displaying the trees. The format must be xpm (X PixMap) format,
see https://en.wikipedia.org/wiki/X_PixMap .
NOTE: when this file is present, no menu will appear. - $HOME/xsnow/pixmaps/santa<n>.xpm
- where <n> = 1,2,3,4. If present,
xsnow will try this files (4 of them) for displaying Santa. The format
must be xpm (X PixMap) format, see
https://en.wikipedia.org/wiki/X_PixMap .
NOTE: when these files are present, no menu will appear.
“EXAMPLES
$ xsnow -defaults # run with defaults.
$ xsnow # run using values from the config file.
$ xsnow -treetype 1,2 # use tree types 1 and 2.
“BUGS
- Xsnow needs a complete rewrite: the code is a mess.
- The flags are not consistent, caused by trying to be compatible with
older versions.
- Xsnow stresses the Xserver too much.
- Xsnow does run in Wayland, but will not snow on all windows.
- Xsnow tries to create a click-through window. This is not successful
in for example FVWM/xcompmgr. In that case, xsnow tries to keep the snow
window below all others, resulting in a transient effect when you click
on the desktop. Sadly, no FVWM menu will appear…
- Remnants of fluffy snow can persist after removing the fallen snow.
These will gradually disappear, so no big deal.
- Remnants of meteorites can persist after passage of Santa. These will
eventually be wiped out by snow or Santa.
- Xsnow tries to adapt its snowing window if the display settings are
changed while xsnow is running. This does not function always well.
- Xsnow does not play well with ’xcompmgr -a’. In some environments
(Raspberry 64 bit) xcompmgr is started with the flag ’-a’, resulting in
a black snow window. Remedy: In a terminal window type: killall xcompmgr
nohup xcompmgr -n & and try again.
- In XFCE, compositing must be enabled for xsnow. Settings -> Window
Manager Tweaks -> Compositor -> Enable display compositing
- In multi-screen environments, it depends on the display settings if it
is snowing on all screens. Experiment!
