Minecraft hides the X11 cursor during normal gameplay, as moving the mouse changes the view of the camera, like in most first-person games.
During gameplay, pressing
e is supposed to open up the inventory, and restore the cursor. (So that you can click things. Minecraft doesn't use any sort of fancy cursor art, it just uses the system cursor here.) Lately, pressing
e will open the inventory, but not show the cursor. The mouse still works fine: hovering over things will cause them to highlight, clicking works just fine. Everything is great except I have no idea (aside from hints from hovering and clicking) where my cursor actually is.
At some point, I hoped exiting minecraft would fix this, so I quit. I still, of course, have no cursor.
In X11, is there a way to force a cursor that's been hidden by a program such as Minecraft to be restored?
