Bug Description

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.

i have the same problem on my Asus x50m. The pointer disappears after KDE restart (ctrl+alt+backspace), after logout and then login, but not every restart or logout/login - it disappears randomly.

i think its related bug.

I think that the duplicate status is wrong, for two reasons: first because I run Xfce and second because the mouse pointer works perfectly after every logout/login. It suddenly disappear when I try to modify the brightness of the screen with the combination of keys of the Dell X200: Fn+up Fn+down.

To bring the pointer back, thanks to a post on ubuntuforums, it suffices to switch to the terminal mode (CTRL+ALT+F1), modify there again the brightness and go back to the graphical mode (CTRL+ALT+F7): the pointer will be visible without any brute force restart...
