[Trisquel-users] notify-send not working

[oralfloss]

I have noticed certain programs display those neat notifications in the  
top-right of the screen, like Ryhthmbox, Transmission, and the  
volume/brightness controls. From what I've read, these are just shell scripts  
that all use notify-osd. I have notify-osd installed, and I have tried  
reinstalling it, but I cannot get the script that displays these  
notifications to work. The script is, at least from what I have read online,  
notify-send. I have tried to get this to work both in DeadBeef to display the  
current song, and in the command line. However, all I get in the command line  
is "bash: notify-send: command not found".

My question is if there is a different command being used by other programs  
which are specific to Trisquel, or if I'm doing something else wrong. Any  
feedback would be nice.
