I'm using the psmouse driver on a Dell Inspiron 17R SE and it makes the touchpad work as an actual touchpad and not just a mouse. However, I'm experiencing a significant amount of backlash. By this, I mean that when reversing the direction of movement the cursor will remain still for some time before it actually moves again. The behavior is very similar to the mechanical concept of backlash, which is nicely explained in this Wikipedia article: http://en.wikipedia.org/wiki/Backlash_%28engineering%29
Could this be a flaw in the driver or in some other part of the software system? Is it just a property of my hardware? I have noticed the exact same behavior on a Fujitsu Lifebook with an ALPS touchpad that also works with this driver. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/606238 Title: synaptic touchpad not recognized on dell latitude e6510 Status in The Linux Kernel: Fix Released Status in “linux” package in Ubuntu: Incomplete Status in “linux” source package in Precise: Fix Released Status in “linux” source package in Quantal: Fix Committed Status in “linux” package in Arch Linux: Fix Released Status in openSUSE: New Bug description: It wrongly recognized as PS/2 Generic Mouse.
