I had this problem pop up a while back with my old Gateway NV49C and I solved it by deleting the nvidia-settings file from my home directory.
currently I have this problem with my new ASUS X550LNV laptop but because I could switch terminals to fix it, it never occured to me that the bug could be the same (the old gateway had dead fn keys). -- 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-graphics-drivers-319/+bug/1220426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
