Hello =)

This is my setup:

Windows Vista 64bit host
1080p resolution at 120 DPI

Ubuntu 8.04 64bit guest
At any resolution - even seemless mode


My problem is that the mouse seems to jump erratically around in the VM and can't reach parts of the Linux desktop. When I change the DPI in my Windows host back to the standard 96dpi, the mouse in the VM responds as expected. I believe the host DPI is not being considered in the calculation when translating the mouse position from the host to the guest.

Check that you've got GA running on the guest properly. It sounds to me as if it isn't running. It can also fail if you have upgraded the Ubuntu kernel without rebuilding the drivers.

Thanks Terry

Its working now. I ended up upgrading the VM to Ubuntu 8.10 and then reinstalling the guest additions.
