Hi, I now have a "fix." Summary: The synaptics drive (provided by 15.04 kernel) seems to be broken. I have replaced it with the stock driver, and now the problems is gone. While this may not be a fix for everyone, but its a great fix for me. I'm now able to use the x250, and the mouse is rock-solid working, after 24 hours of testing.
The one major issue with this fix is that the touch pad is disabled. But I cant use the touchpad anyway, so this fits my needs perfectly. Why cant I use the touchpad? When I type, the left pad of my right hand, between the thumb and the wrist, touches the touchpad, causing the mouse to go crazy. This is because I touch type, vs peck with raised hands. Therefore the touch pad is dysfunctional, and I must turn it off. What is the fix for the mouse button "sticking"? I followed up on the lead provided at: https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X250#Mouse which also references the much older: http://vimtips.org/2015/02/20/ubuntu-1410-and-lenovo-thinkpad-x250/ which solved the mouse-sicking problem, at the price of loosing the touchpad function (which I didnt want anyway). Here is the procedure , step by step: 1) /etc/modprobe.d/psmouse.conf Add to this file options psmouse proto=imps 2)create a file /usr/share/X11/xorg.conf.d/90-evdev.conf containing: Section "InputClass" Identifier "Touchpad/TrackPoint" MatchProduct "PS/2 Synaptics TouchPad" MatchDriver "evdev" Option "EmulateWheel" "1" Option "EmulateWheelButton" "2" Option "Emulate3Buttons" "0" Option "XAxisMapping" "6 7" Option "YAxisMapping" "4 5" EndSection 3) Reboot Problem solved. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1506817 Title: left TPP/2 IBM TrackPoint "sticks on" randomly (X250 15.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1506817/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
