[ale] unusual cursor behavior - don't know where to begin

[James P. Kinney III]

Disable gpm at start up (chkconfig gpm off) so only X has mouse
controls. This sounds like a mouse conflict between console and X
control of mouse data. gpm is not needed for mouse events in X.

If that doesn't work at least the issue has been narrowed down to a pure
X environment problem.

Since it happens with both Gnome and KDE, it must be the underlying
mouse driver. It is possible that there is some memory corruption
causing errant behavior that only appears under load. Try running
memtest86 and beat the RAM up for a while.
