Hi, I am still having that issue on 14.04 Lenovo T540p with nvidia-prime activated.
I had suspected it is 'Disable while typing' option in Mouse&Touchpad configuration however disabling the option does not solve the problem. At the same time 14.04 on Dell V131 does not have any issues with touchpad at all. Switching to any virtual console and back C-A-F7 is a workaround as mentioned above however does not solve actual problem. I wonder it is still 'Disable while typing' issue because I had similar issue in a past. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1277245 Title: nvidia prime causing mouse and screen to freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1277245/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
