Comment 35 for bug 1506817

Status of X250 bug:
In comment #29 above, I mentioend that following the install of the latest kernel the
LMBS = "Left mouse button sticking"
bug remained. But unfortunately the working kernel then stopped working, leaving me with not recourse but to abandon
the machine. The X250 is not usable with this but. As I stated in #29 I switched to an old machine. I have many options,
and right now I'm using my old X220i. This has a trackpad, which I can either turn on or off in the BIOS, and when it is on in
the BIOS I can turn it on and off from linux. The X220 is working fine, and the X250 now has the LMBS 100% of the time,
and for all kernels that I boot.
I am happy to continue to pursue this, but have sort of lost hope that this will be fixable, without some major new insight(s).
I say this with insight I have obtained by comparing the X220i behaviour with that of the X250. The BIOS interaction is different, leading me to believe that the BIOS has a bug. It is not possible to turn off the TP with the X250 BIOS, as I can do with my older X201i, and the X220i that I'm presently using for daily work.

Just to remind you, I upgraded the X250 to Ubuntu 16.04 Beta 2. Now the LTS is out, so I will likely upgrade to that.

Right now I'm travelling, so I dont have access to the X250, but when I return home (tomorrow), I will download and boot 4.6-rc4, as you request and post an update.
