Mouse cursor suddenly disappears
In Xubuntu 7.10 Gutsy Gibbon I experience a really strange flaw: sometimes (and I'm not able to understand why) why) the mouse cursor suddenly disappears!!
What happens is that I can still click on everything, but the pointer is "invisible" and I was not able to make it visible again.
I tried to logout and login again or to restart X but my cursor comes back only after reboot.
I was neither able to link the disappearing of the cursor to any application.
I'm unable to induce the disappearing of the pointer, but it happens frequently...
I have a Dell Latitude X200 and installed the released version of Gutsy Gibbon (not r.c.): no compiz neither Xgl.
EDIT: I discover a way how to reproduce the bug. It's enough to use the combination of keys Fn+up or Fn+down, that is the combination to increase or decrease the brightness of the screen in my laptop. I think it's a bug related to Xfce and never described before.
Many thanks for the help.
