[Bug 1431931] Re: T450s thinkpad physical buttons not configured properly

 

Problem resolved upstream -- details here:
https://bugs.freedesktop.org/show_bug.cgi?id=88609

An easier temporary workaround is to create a file in /etc/modprobe.d/
called psmouse.conf and put the following line in it:

options psmouse proto=imps

Then do sudo update-initramfs -u

I'm hopeful that the patch from freedesktop.org will be backported to
Trusty's kernel soon.
