It was interesting thing when I tried to switch back to bumblebee from nvidia-prime. I have done these steps: sudo apt-get purge nvidia-prime sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install nvidia-331 nvidia-settings sudo apt-get install bumblebee bumblebee-nvidia primus primus-libs-ia32
But then I started World of Goo (from Steam) using optirun. And when in game startscreen I've pointed to profiles icon - there has been a freeze again! I removed bumblebee, primus, nvidia-331. After that I installed nvidia-319-updates, then bumblebee and primus. And now i have no freeze at all. So I think the bug is not in nvidia-prime but in nvidia-331driver, because with nvidia-319-updates there's no freeze. -- 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: Confirmed Status in “nvidia-graphics-drivers-331” package in Ubuntu: Confirmed Status in “nvidia-prime” package in Ubuntu: Opinion 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.
