I occasionally experience the same issue in Arch Linux when my touchpad got one 'finger' 'stuck' so that whenever I touch the pad, it scrolls instead of moving the cursor. If I disable scrolling in the settings manager, then nothing happens when I try to use the touchpad. The issue seemed to be resolved after suspending and resuming the computer. I have not tried ctrl+alt+Fx keys, but I imagine that would likely do the same thing.
When the issue last occured, I had just switched desktops to a desktop with a program running on it that seems to hang for a moment before allowing the desktop to render. I presume this may have caused a 'touch release' event to get missed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991707 Title: Mouse pointer (touchpad) gets stuck often To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/991707/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
