[Dell Latitude 6430u] Trackpoint does not work on 12.04.5

[Po-Hsu Lin]

CID: 201208-11536 Dell Latitude 6430u

The track point does not work on this system with 12.04.5 dailylive image (8/3)
It's detected in xinput list, but not working at all, this could be a regression.

The trackpoint works on another machine of the same model and config on 14.04.

@phlin
Could you give 14.04 a try?

[Po-Hsu Lin (cypressyew)]

14.04 LiveUSB, not working.
12.04.2 (certified), still not working

Even with BIOS upgraded from X28 -> A02, it's still not working

I can't recall whether it works or not back on 12.04.2,
we don't have an explicit test case for it at that time.

But I know it's working on 201208-11537, which is unfortunately dead now
With the keyboard module swapped, the Trackpoint on the keyboard from 11537 does not work on 11536, I would say maybe it's a hardware issue. (if it cannot be reproduced on the same model)

[Anthony Wong (anthonywong)]

ok, I am assigning to Keng-yu to check if it is really hardware issue.
