>Sworddragon - what is the difference between the systems where you see the issue vs. ones you don't?
My host system is an Ubuntu 12.04 dev 64 bit and my both guest systems are an Ubuntu 12.04 dev 32 bit and an Ubuntu 12.04 dev 64 bit. There are differences in the hardware. For example my host system uses a GeForce 8600 GT and the guest systems are using some emulated graphic from VirtualBox. There are some differences of the main packages from both guest systems to the host system: + bzip2 + xserver-xorg-video-vesa - libglu1-mesa - libvdpau1 - nvidia-current - nvidia-settings But I have today tested this again with X-Server 11.4 and this bug doesn't appear anymore on my guest systems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/928930 Title: Scrolling using the center wheel bounces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/928930/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
