https://bugs.launchpad.net/dell-sputnik/+bug/1651635?comments=all at least in terms of perceptible problems. 1. Occasionally, some type of interaction with the touchpad puts it into a mode where it barely works. Seems it gets stuck in "scroll mode" or something similar. 2. Happens a couple times a week. 3. In my case, it seems to happen by brushing my left palm in the upper left corner of the touchpad. 4. Symptom: gliding my finger across the touchpad like normal does not work. The middle and right side of the touchpad seem to be in scroll mode, i.e. I can scroll a browser window up & down but I can't move the pointer around. If I use the upper and left borders, the pointer seems to work as normal. Physical clicking works, right click in the lower right quadrant doesn't work. It's almost like the middle and right side of the touchpad are operating as if every touch is a two finger touch. 5. In the past, it seemed as if nothing but a restart would get it out of this mode. However, while filing this bug report, I just realized that repeated two finger scrolls in the middle of the touchpad seemed to unlock it from scroll mode. Then again, this could be a fluke of time or something, since I usually restart before I let the problem go on this long. I'll test more and report back here the next time it happens. Happy to run commands to help troubleshoot.
