Hi, just finished installing ubuntu 14.04 on my alienware mx17r3 with gt540 (Nvidia 331,38) and intel card. exactly the same problem. ctrl alt f1/f7 repairs it. but it's annoying.
also only seems to happen when using touchpad, external mouse or keyboard jumping and everything is fine Made and attached bug report just in case ** Attachment added: "nvidia-bug-report.log.gz" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-319/+bug/1220426/+attachment/4173129/+files/nvidia-bug-report.log.gz -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-prime in Ubuntu. https://bugs.launchpad.net/bugs/1220426 Title: [nvidia-prime]Freeze while using touchpad Status in “nvidia-graphics-drivers-319” package in Ubuntu: Triaged Status in “nvidia-graphics-drivers-331” package in Ubuntu: Triaged Status in “nvidia-prime” package in Ubuntu: Triaged Bug description: I'm using an Optimus laptop (Asus N43SL) nvidia-prime is installed, so my nvidia dedicated graphics card (GT 540m) is in use. Once in a while, my screen will freeze, only when I use my touchpad. This does not happen with my USB mouse. This does not happen either when I uninstall nvidia-prime and use my intel integrated graphics (HD3000). I can temporarily solve the issue by doing a VT switch. In the attached Xorg.0.log, you can see "synaptics: ETPS/2 Elantech Touchpad: touchpad found" each time I did a VT switch and regained control.
