in message #34 you requested that In install 4.6-rc4
In message #36 I discussed 4.6-rc5, which did not resolve the issue.
in message #34 based on your request, I installed rc4, which did not resolve
the issue.
in message #17 I used 4.5-rc3 (NOT 4.6), and it did resolve the issue.
in message #21 I state:
"I was running kernel 4.5-rc3 and everything was great. Then sometime around
Feb 3, 2016 (I don't know the exact date),
following an standard upgrade from Ubuntu, the old symptoms (left mouse button
sticking) returned."
This abrupt change was not due to a kernel change. I was running
4.5-rc3, before and after
After Feb 3 the X250 was unuseable no matter what I did. If you read the
details, I tried all sorts of things. I even
reinstalled the OS from scratch and tried to reinstall 4.5-rc3, from scratch.
To no avail. Nothing worked.
NOTE: the USB mouse has always been totally functional, and the trackpad
and trackpoint work, but the left mouse button sticks on, rendering the
computer useable.
Eventually I was forced to switched over to my previous computer X220i,
which has both a trackpad and trackpoint. This machine works perfectly.
The X250 is sitting in the corner, unuseable (unless I downgrade to a
USB mouse, which works perfectly on the X250).
In my last attempt, today April 30, 2016, I swapped computers with my
wife, so I now have her X250. That functions exactly as my X250. This
rules out any hardware issues.
It is noteable, IMO, that the BIOS in the X220i and the X250 behave very
different wrt the synaptics mouse, as documented
in message #35.
Status today: I'm using the X220i for daily work. The X250 still has the mouse
bug.
None of the kernel and BIOS changes had any effect at all.
The X250 spontaneously stopped working on or about Feb 2, following a standard
upgrade (not a kernel change!)
Chris, I appreciate your attention to this, but I think we need to get
to a new level re this problem. If the community wishes to continue to
use X series thinkpads (I'm sure they do), then this problem needs a
resolution.
What will Lenovo come up with next? Is the beginning of the end of
Thinkpads and Linux?
I have more than 10 of these X-series laptops lying around my office.
I've been using X hardware for many years. I see this as the end of the
line, all due to a stupid mouse driver bug.
Please correct me if I'm wrong in my summary.
