Precision 5510 jumpy touchpad in BIOS and X
I've just received a Precision 5510 and have been setting about installing Arch on it. While fiddling around in the BIOS setting boot order etc. I noticed the pointer jumping erratically, but didn't give it as much thought as I should have done. I've now got to the point of starting X after wiping and reinstalling Arch over the Ubuntu that shipped with the device, and I'm experiencing the same, I believe touchpad related, pointer jumping as before.
Has anyone else experienced this? Is it likely to be a hardware fault needing a return? Or something which would be fixed by a BIOS or other firmware update ... the machine shipped with BIOS version 01.02.00, while the latest is 01.02.10. Or something which would be fixed, at least in X, with a device specific driver installed?

Thanks for the pointer. I can confirm that libinput does the trick under X. Strange that the touchpad is enabled but unusable in the BIOS.

Unfortunately that seems to have only been a temporary fix :-(

I'm now wondering if it's the touchscreen which is the culprit rather than the touchpad.
I'd disabled it and will report back.
Apropos touchscreen firmware ... I see that there's an update available ... how would that be installed without a Windows machine available?
