You have been subscribed to a public bug: On MSI GT60-20C with Ubuntu 14.10, the touchpad freezes the XServer when combining LeftClick + Tap, or multifinger taps.
As a workaround, I was partly initializing the XServer by performing a Ctrl+Alt+F1 then a Ctrl+Alt+F7. The touchpad continues to work after this. I tried to dig deeper into the problem, so when the XServer freezed again, I continued to move the cursor to a known place, I performed after my Ctrl+Alt+F1/F7 combination, and found the cursor in a different place after freezing. This actually means that when the XServer freezes it only stops rendering the place of the cursor. I got an idea, and installed Gnome Pointing Devices; I changed the settings of Vertical/Horizontal scrolling and the problem seemed to occur less up till now. EDIT: It happened again, I was watching a video, the video continued to play but the compositor stopped rendering the screen. I am running the proprietary NVidia binary driver on my OS (NVidia GK106M GeForce GTX 770M version 331.104 from nvidia-331) ** Affects: xorg (Ubuntu) Importance: Low Status: Incomplete ** Tags: utopic -- Touchpad freezes XServer when using multifingers https://bugs.launchpad.net/bugs/1393412 You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
