I'm running Ubuntu 14.10 on my Lenovo Thinkpad X240. Since I dislike the new clickpad and because I use the trackpoint always anyway, I disabled the trackpad functionality and only kept the button functionality active as discribed in various tutorials on the internet:
# $ cat /etc/X11/xorg.conf.d/99-x240-clickpad.conf Section "InputClass" Identifier "tp only with clickpad buttons" MatchDriver "synaptics" Option "ClickPad" "1" Option "EmulateMidButtonTime" "0" Option "SoftButtonAreas" "60% 0 0 0 40% 59% 0 0" #Emulate right and midle buttons Option "TouchpadOff" "2" Option "AreaBottomEdge" "1" #disable moving but not buttons EndSection
This works rather fine. However, sometimes the buttons are not recognized: There is middle-button on the whole left + middle part then, or maybe right button on the complete area, or similar messe.
I suspect this happens after waking up from suspend, but only sometimes and not immediately after resume. I can sometimes fix the behavior by executing another suspend/resume cycle and sometimes it fixes itself after a couple of minutes.
There are no significant errors in the syslog which I can assign to the shown behavior.
Does anyone have a clue what is going wrong and hopefully how I can fix it?
