Note: Bug is still alive in october 2015 - that is nearly 25 months old ! == My config Fully up to date 14.04. Nvidia GTX 950M + Integrated Intel Asus ROG G551J Elantech Touchpad
== Elantech Touchpad, the common hardware After seeking on the net, I've find (here: https://devtalk.nvidia.com/default/topic/766166/elantech-touchpad-related-nvidia-driver-freeze/) that many people who experience the bug have an Elantech Touchpad and are using the synaptics drivers. To check if you're in the same situation: $ cat /sys/class/input/mouse0/device/name ->> ETPS/2 Elantech Touchpad == Proposed workaround It seems that the following workaround works, although I can't promise anything. We are however all expecting that NVidia developers fix their drivers properly. $ sudo apt-get remove xserver-xorg-input-synaptics-{your-flavour} $ sudo apt-get install xserver-xorg-input-mtrack-{your-flavour} Hope you're doing better with that solution ;-) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1220426 Title: [nvidia-prime]Freeze while using touchpad Status in X.Org X server: Fix Released Status in xorg-server package in Ubuntu: Fix Released Status in xorg-server source package in Trusty: Triaged Bug description: Using Asus N43SL laptop as an example, with nvidia-prime installed, so the dedicated NVIDIA graphics card (GT 540m) is in use, once in a while, my screen will freeze when I use my touchpad.
