Touchpad not working on ThinkPad Edge e540 [SOLVED]
Dear Everyone,
About a week ago I received my new ThinkPad Edge E540. While installing Arch Linux wasn't as smooth as I was used to (mostly due to UEFI while being used to BIOS), I got it working that day. I was however experiencing some problems with the touchpad. As it was quite large, I would touch it with my palm while typing. I'd tried various different settings concerning palm detect etc, and was well on my way to getting it to respond to my liking.
Then, this morning I booted up, and my touchpad seems to respond only barely! I have to physically press the pad (which should correspond to a mouse click) in order to get the cursor to move at all. I have tried removing any custom config files (/etc/X11/xorg.conf.d/50-synaptics.conf), reinstalling the touchpad driver but nothing seems to work.
This is the output of xinput:
⎡ Virtual core pointer id=2 [master pointer (3)]

Re: Touchpad not working on ThinkPad Edge e540 [SOLVED]
I have an e540 too and didn't have issues with my touchpad except for palm detection problems. I am using syndaemon to disable touchpad while typing now.
Did a diff on our settings and the only settings which are different on my setup are:
FingerLow = 25
VertEdgeScroll = 0
HorizEdgeScroll = 0
VertTwoFingerScroll = 1
TouchpadOff = 0
TapButton2 = 2
TapButton3 = 3I put at button on it. Yes. I wish to press it, but I'm not sure what will happen if I do. (Gune | Titan A.E.)

Re: Touchpad not working on ThinkPad Edge e540 [SOLVED]
Thanks! This unfortunately didn't help.
I did find something weird though. Looking at the touchpad using evtest, I get a constant stream of events, even when not touching the touchpad. The events fired are:

Re: Touchpad not working on ThinkPad Edge e540 [SOLVED]
While not touch the pad I don't get events with evtest.
But when I put my finger onto the pad (without moving it) I get exact these events you get. It seems as if you got a ghost finger on our touchpad 
Does your touchpad work on other OS(e.g. windows..) ?
I put at button on it. Yes. I wish to press it, but I'm not sure what will happen if I do. (Gune | Titan A.E.)

Re: Touchpad not working on ThinkPad Edge e540 [SOLVED]
I haven't tried in Windows, as there is no way (that I know of) to boot a live image of windows. I did just try it on a live version of Ubuntu, and that shows the exact same behaviour... I'm starting to suspect something is physically defective with my touchpad.

Re: Touchpad not working on ThinkPad Edge e540 [SOLVED]
I've got it working again! I just booted the recovery disc that came with the laptop, to try and see if the touchpad would work in de installation menu's. It did, so I was relieved of my worry whether the touchpad was physically defective. Then, when I booted back into linux, it worked there too!
Just for completeness sake, I'll post my config files, just in case anyone runs into the same problem, and I'll mark this thread as solved:

Re: Touchpad not working on ThinkPad Edge e540 [SOLVED]
Nothing to add on topic, just to say that I'm another happy E540 owner. Everything works on mine, except the fingerprint (but I don't care about it).
I had (and solved) the following:
- ThinkPad LED (the i's dot) sometimes kept blinking after waking up from suspend
- ClickPad soft buttons did not work as it should (left, right, middle)
- Tap and drag unreliable (Double tap for Tap and Drag too fast)
- Wireless rtl8723be (with 3.16 it stopped transmitting data)
- Suspend broken (disable USB 3.0 in BIOS, the ports will work as 2.0)
- Backlight not saved (always starting at full brightness)
I'm planning to add the solutions I've found on ThinkWiki, but if you hit any of them yourselves then just create a new topic and I'll reply there (please notify me if I don't seem to reply).

Re: Touchpad not working on ThinkPad Edge e540 [SOLVED]
Hi,
I have a Lenovo Z5070 Laptop. I Installed Arch Along with Windows 10 in dual boot setup and guess what? I had the same issue. I rebooted into Windows Same problem. I did a hard boot and now it works fine. Mysterious but fixed .. Not sure what fixed it. I have never faced anything like this in all these years.

Don't necro-bump. Not only did you revive an old thread that should be left alone, you have also added nothing of value, don't do that.
