Recover from invisible mouse due to misconfiguration

The linked wiki page describes a scenario whereby a misconfigured monitor width and refresh rate causes the mouse cursor to be completely invisible. Fortunately, it was possible to login (ssh, actually) as another user, and manually edit the configuration file. In that case, I was fortunate that I knew the exact time of when the problem started occurring, I had a working user, so I simply had to compare files changed at that time, between the working and non-working users.

KDE/ should allow the user to recover easily from such misconfiguration.

Invisible mouse cursor

An invisible mouse cursor is most likely caused by a failure of the X Windows graphic drivers.

Please update this page with other causes which may cause the mouse cursor to be invisible, links to upstream bugs, and the solutions.

I am currently looking for information regarding mouse pointer jumping across the screen, to some corners while I'm doing nothing with the mouse. It's a new 3 button wheel mouse on a desktop computer. No touchpad involved.
