Did you build psmouse.ko from my DKMS sources, or apply the patches on top of some other baseline? > But the input events seem very noisy (E.G. the cursor jumps up and down > if I keep my finger pressed on the touchpad). Especially the Y > coordinate seems unstable: OK - I do see this on E6230 but not E6430. Normal usage is fine but the "pressed finger" test fails on E6230. I'll do some digging and try to figure out why. In another thread [1] it was mentioned that the ALPS_BITMAP_* constants needed to be tweaked for the Rushmore touchpads. This might be related. I also saw some "lost sync" errors in the kernel log on E6430 after running for a few days, but I don't know how to reproduce the issue. They did not seem to be associated with any obvious touchpad misbehavior.
