I solved the problem by downgrading xserver-xorg-input-synaptics to the previous version via synaptic (Package-Menu->Force version). I had to unmark the package after the downgrade to prevent from being immediately upgraded again. To really lock the version of the package I used "Apt-Pinning".
I added the following lines to /etc/apt/preferences: Package: xserver-xorg-input-synaptics Pin: version 0.99.3-2ubuntu4 Pin-Priority: 1000 -- Touchpad gets stuck and is generally unresponsive https://bugs.launchpad.net/bugs/372090 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
