My Acer Aspire ES1-111-C138 is running Arch Linux more or less smoothly now. *yay* However from time to time I have to use the touchpad. And sometimes after a while of using it, the cursor starts doing random movements, mostly up and down. I ran evtest to see what's happening. Here's the output

Input driver version is 1.0.1 Input device ID: bus 0x18 vendo Input device name: "SYN1B7D:01 Supported events: Event type 0 (EV_SYN) Event type 1 (EV_KEY) Event code 272 (BTN_LEFT) Event code 325 (BTN_TOOL_FI Event code 330 (BTN_TOUCH) Event code 333 (BTN_TOOL_DO Event code 334 (BTN_TOOL_TR Event type 3 (EV_ABS) Event code 0 (ABS_X) Value 582 Min 0 Max 1223 Resolution 12 Event code 1 (ABS_Y) Value 235 Min 0 Max 684 The unwanted cursor movements start at line 1978. If I disable the touchpad via the function key on the keyboard, it stops moving of course. If I then reactivate it, it's sometime usable again, sometimes it still wiggles around... For completeness, here's my touchpad configuration:

This is a common issue and is actually an hardware one (kind of electric isolation issue). See here on this french e-vendor: http://www.fnac.com/PC-Ultra-Portable-A … 384098/w-4 The solution is to contact acer for a repair.

Hope it helps and sorry for my poor english Offline

Hi,


#3

thanks, I was thinking about something like that as well. However I didn't find time to look into this any deeper in the last couple of months. I actually use the netbook mostly on my desk with a mouse attached which, thanks to i3, I dont use that much anyway. But now that it really looks like a hardware issue, I might as well try to contact them and see what they can do for me...

Hi I had similar problems with my Acer Aspire V3. Here's what I figured out:


#4

Modern synaptics touchpads provide two modes of operation: one via i2c and one via ps2. There's no proper driver yet for the i2c mode, but the ps2 mode works just fine. The problem however is, that once the touchpad was detected as an i2c device it shuts down the ps2 mode until the next reboot. The solution is to blacklist the i2c-hid module so the device isn't initialized in i2c mode and the ps2 mode remains active. On my machine I had to additionally set i8042.nopnp=1 on the kernel cmdline. Else the touchpad didn't work at all in ps2 mode. However you might not need this, or you might need i8042.nomux=1. Just try it out. Offline

Hi mirco,


#5

thanks, this actually makes things a lot better, although sometimes I still have my cursor jumping all over the screen... But it`s much less frequent now. So maybe it`s not a hardware issue... Fabian.

I may got what the main issue is... Here is how I solve this issue(forgive my poor English...) I disassembled the laptop (acer E13 ES1-311) and move the battery module aside, finding that the wire connecting the speaker is below the touchpad module. And after I rearrange the wire(put it beside the module, just not below, since it may leads to pressure on the touchpad), and then this touchpad doesn't "berserk"!!!!! Maybe you can try this, and maybe this is a hardware issue...


#6

And i thought that maybe the problem is that the wire produced a new "capacitor", and lead to this problem due to type of this touchpad(just like our smartphones). Last edited by b546mmmpm (2015-06-25 13:01:17)

Hi all,


#7

a little update: I have to take back what I said in my last post: The changes I did didn`t really change that much, my first impression was obviously wrong. However, I booted the same netbook from my Arch USB Stick and didn`t have any issues during that time, which was about an hour I think. So - at least for me - it must be some config issue...

The situation for me (E3-112-C43A) is exactly the same. It's not a problem of detecting the touch-/click-pad, it's a random cursor spinning problem. No kernel parameters e.g. "i8042.nomux=1 i8042.reset" are helping (suggested in https://bbs.archlinux.org /viewtopic.php?id=185329). Unfortunately, the problem cannot be reproduced reliably: With the clickpad enabled, the cursor will enter berserk mode after 1-2 hours of uptime sometimes it doesn't happen during a whole work session - then after some restarts the issue happens again, randomly, only some seconds after booting. The temporary solution for me is to disable the clickpad using Fn + F7 and to use a USB optical mouse. Which is of course annoying! @Dunkit: maybe you haven't used the system booted from your USB device long enough to reproduce the situation? After all the threads I read about this on the net, I have the feeling that this not a configuration problem. BTW: I also get these error messages:

i2c_hid i2c-SYN1B7D:01: failed i2c_hid i2c-SYN1B7D:01: failed i2c_hid i2c-SYN1B7D:01: failed i2c_hid i2c-SYN1B7D:01: failed input: SYN1B7D:01 06CB:2991 UN hid-multitouch 0018:06CB:2991. Are there any alternative drivers / kernel modules we could try for this clickpad? At the moment it seems there is no solution available. I would also consider the suggestion posted by b546mmmpm, as I do not want to install Windows just to check if it doesn't happen there. I'll post an update if there are any news.

After all the threads I read about this on the net, I have the feeling that this not a configuration problem. Don`t think so. Usually I get the effect pretty much right after I enable the touchpad. Say within 5 minutes at most. And I worked with that USB Stick for at least an hour. But I hope I`ll get a chance to test that again over the weekend...

I can now confirm what b546mmmpm has stated: The speakers audio cable crosses and even touches the connection cable of the touchpad. After I've added more isolation between them, the problem was solved! No more cursor jumping! @b546mmmpm: Thank you!

jmeinke, was that an easy thing to fix or was it hard to open the netbook, find the right spot, etc.?

It was quite easy. I first had to take off the back cover of the netbook by unscrewing all screws (about 10). Then I had to raise the battery by unscrewing two more screws (the battery is located right behind the touchpad). Afterwards, I put a thin layer of synthetic material between the speaker cable and the touchpad cable. I didn't need to modify the setup of any cables. P.S.: The material I used was the packaging of pocket hankies (gefaltete Plastikverpackung von TempoTaschentüchern).

Dunkit, generally speaking I recommend you find some dis/assembly guide e.g. on youtube or a detailed documentation (some webpages archive these). these things have to be dis/assembled in a particular order, and sometimes you just have to know which magic point to press so it comes apart. in addition to screws, there's always a few plastic snap-on thingies; they can be opened a few times, but not too often. ... actually, wth, here's a sensible-looking youtube video: youtube.com/watch?v=5OT_RnjMess with the

video it's easy enough, trust me.

ps: make sure you have a plastic seperator tool (a guitar pick will do nicely). Last edited by ondoho (2015-08-06 13:24:58)

Did the same isolation trick as jmeinke, but with no luck. Also didn't see the touchpad cable touching another cable anywhere else...

I have the same problem on Acer TravelMate. This, for sure, is my last Acer computer.


#15

From evtest, it seems to me that the random moves are *not* preceded by a BTN_TOUCH=1. Could someone, as a temporary fix, patch xf86-input-synaptics so that interaction is basically entirely deactivated if the BTN_TOUCH=0? *Edit*: I went with moving the cable below the touchpad's bus, and well, it worked. Flabbergasting. It took less than 5 minutes. Thanks so much for the suggestion! Last edited by cadilhac (2015-12-30 12:23:56)

Here's my (hopefully) final solution (Thanks to Cooper, who had the same problem):


#16

Assuming your BIOS version is >=1.08, change "Touchpad" from "Advanced" to "Basic" in your BIOS. If you're like me and your laptop came with BIOS version 1.03, say a big THANKS to Acer, who only offers BIOS update tools as Windows executables and doesn't even answer my support ticket. Then, get a Windows Live System on a USB stick (if you're German, consider http://www.heise.de/ct/ausgabe /2015-26- … cle-links), update your BIOS from that system and voilá, you're there. I haven't noticed any problems with the touchpad so far, but I'll keep you posted... Offline

Both the "Basic" setting and the wire move failed me on the long run. I'm simply pissed. Some people recommend welding things, what a shitty piece of crappy hardware. Acer never again.

Hi all.


#18

I have a quite similar issue but with a Hp Probook 455 G2. In my case the touchpad randomly stops working, the pointer starts dancing on the screen and any movement on the toucpad is fruitles (be it a simple sweep left or right). In my case unloading and reloading the touchpad module helps, but only for a short period of time. Usually the strange behaviour starts after 10-15 min after boot or 3-5 min after reloading the kerel module. Any suggestions?
