Lucid Lynx - Increasing monitor resolution results in invisible mouse pointer.

Binary package hint: xorg

Tested on two almost identical Compaq Deskpro Evo's. One with 10.04 installed + CRT, and the other running 10.04 live from a CD + LCD detected as Hewlett Packard 17".

The Live CD boots, and runs at monitors max resolution. Reducing and then increasing resolution works except that the mouse pointer is no longer visible. Mouse is otherwise functional. Reducing the resolution again brings the pointer back.

To reproduce:
1 Boot from CD - selecting Try Ubuntu 10.04
2 Run the "Monitor Preferences" applet ( System->Preferences->Monitors )
3 Reduce the resolution and click 'Apply'
4 Either let the dialog box time out or click button to return to previous resolution.
5 Note the missing pointer!

From my experimentation, it seems any increase in resolution, whatever the method, results in a missing pointer, however a decrease in resolution does not.
