inotify watch limit reached

[gornostal]

Ulauncher watches Documents folder, so you can quickly find a file using find keyword.
Sometimes underlying library inotify requires more watchers than OS provides by default.
By following this procedure you can increase a number of watches http://askubuntu.com/a/148177
Don't forget to restart Ulauncher after that.

Solution:

echo fs.inotify.max_user_watches=100000 | sudo tee -a /etc/sysctl.conf; sudo sysctl -p
