I wonder if this is a VirtualBox problem. Creating an Ubuntu VM seems to have Mouse Integration enabled by default.
Work around: Selecting the VirtualBox 'Machine' menu on the VM window and clicking on 'Disable Mouse Integration' makes the cursor visible inside the Ubuntu VM. Once you have clicked in the VM window to get its attention. This would explain why installing the Guest Additions package fixed the problem. It might be a co-ordination problem between Ubuntu and VirtualBox about what they are assuming, or maybe VirtualBox are just assuming that all OS's can support Mouse Integration as is. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/924014 Title: Cursor not visible in virtualbox install of ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/924014/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
