Public bug reported: 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. ** Affects: nvidia-prime (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Xorg.0.log" https://bugs.launchpad.net/bugs/1220426/+attachment/3801516/+files/Xorg.0.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1220426 Title: [nvidia-prime]Freeze while using touchpad To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1220426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
