The scroll problems seem to be related to the 'idle time' support of syndaemon that disables the touchpad briefly after typing. If I hit 'enter' to free up scrolling, then disable that feature entirely (via the kde touchpad config, which I assume is restarting the daemon with new settings), all of the scrolling issues go away. However, if scrolling isn't working when I disable that feature, then scrolling never unlocks. So definitely seems like the timer associated with that interval is never completing.
Although, strangely, when I do disable the interval (via the kde touchpad config), the typing still causes scrolling to be temporarily disabled... Will dig a little deeper. But in the meantime, the xorg patch + disabling syndaemon typing intervals is the winning combo. -- 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
