Mouse integration cannot be disabled -> fixed in SVN after 3.2.0

[lkgrg]

In VirtualBox 3.2.0 with matching guest additions installed, I'm unable to disable the mouse integration. The button is greyed out. Host system is openSUSE 11.1-64, guest system is either openSUSE 11.1-64 and openSUSE 11.2-32.

vbox 3.2.0, host OSX 10.6, guest Ubuntu 10.04, same problem.

​http://www.virtualbox.org/ticket/3880 and ​http://www.virtualbox.org/ticket/5672 are related and explain why this has become critical for my use case.

To me this sounds as if it is caused by the newly added virtual USB tablet support. When the guest starts using this device (and I would assume all recent guest OSes will do this automatically), then it uses an absolute pointing device, which enables something extremey similar to the "mouse integration" provided by guest additions. It's not the same thing though, as for this feature you don't even need guest additions.

Anything I can try in the guest to confirm that ? The guest is lucid lynx (Ubuntu 10.04).

You could make an experiment, disabling loading of the "usbhid" kernel module. This would be the most precise way of confirming.

A much more coarse way would be to disable USB support in the VM config.

Replying to klaus:

USB *is* (and was) disabled.

Adding 'blacklist usbhid' to '/etc/modprobe.d/blacklist.conf' file doesn't work, modprobe -l stills lists it :-/

Same thing with 'modprobe -r usbhid', is there other means I'm not aware of ?

But lsmod doesn't list it, whether or not I try to remove it.

Also, is there a way to install both 3.1.8 and 3.2.0 on the same host (not trying to run then concurrently of course).

So far I can use the same vm with both versions (pfew, thanks) but I keep installing one version on top of the other (thanks for making that possible too).

[Klaus Espenlaub]

Then my guess was wrong, and it needs to be fully investigated.

And no, there's no way to install two VirtualBox versions at the moment.

Fixed in r29750. A capability flag was getting squashed, making the guest think that the host didn't support disabling mouse integration.
