unclutter 8-25 (riscv64 binary) in ubuntu lunar

 unclutter hides your X mouse cursor when you don't need it, to prevent it
 from getting in the way. You have only to move the mouse to restore the
 mouse cursor.
 .
 This is the original unclutter implementation from the 90s which
 works well with classic X11 programs. For a more modern
 implementation which works better with some more modern applications
 and UI libraries, see unclutter-xfixes.
