I'm having this issue since the first boot of my new Dell Inspiron 5558 (with Nvidia GeForce 920M), and that's about 15 days already. Tried like millions of solutions including ones I found here, but nothing worked for me. Reinstalled Ubuntu for 20 times I think, from 14.04 to 15.10, tried UEFI and legacy boot (as someone somewhere suggested this as solution too), modified that one .conf file in modprobe.d as someone else suggested, added xorg-edgers repository and pulled the packages from it... I can't remember anymore what else I tried, but nothing helps.
Touchpad (pointer) freezes randomly without recognizable pattern. Sometimes right after the boot, sometimes 5 minutes after, sometimes one hour after, but eventually it will freeze, sonner or later. Sometimes it does not only freeze, it starts to act weird, opening right click menus while still frozen, like randomly generating all kinds of touchpad inputs. Sometimes it fixes itself after closing/opening laptop screen (going to suspend and waking), but this is not working every time also. This is driving me insane. I love Ubuntu for years and I love my new DELL Inspiron, but having the laptop with defective touchpad defies its very purpose. -- 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/xorg-server/+bug/1220426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
