Unclutter
Unclutter hides your X mouse cursor when you do not need it, to prevent it from getting in the way. You have only to move the mouse to restore the mouse cursor. Unclutter is very useful in tiling window managers where you do not need the mouse often.
Installation
Install unclutter from the official repositories.
Usage
Use your .xinitrc file or WM/DE to start unclutter, for .xinitrc add:
unclutter &
If you experience issues when using unclutter in conjunction with a tiling window manager (such as xmonad or i3), use the -grab
option:
unclutter -grab &
Known Bugs
Misbehaviour of the mouse cursor
Unclutter could cause unusual mouse behaviour in some SDL Games. The mouse cursor might be reset to some positions in the screen because of this problem. The details can be found here.
There are two known workarounds for this. You can either add SDL_VIDEO_X11_DGAMOUSE=0
to your environment variables which does not work for all games or run unclutter with
-grab
option. However, it is important to note that the grab option may cause some applications such as gksu to not work properly.
