Hello.


EDIT: Kernel configuration obtained by further experimenting can be found later in this thread, and command line turned out to be different. See this message.

I recently bought an Acer Aspire V3-371-37AC laptop (equipped with Intel Iris 5100) and like many other people found out touchpad issue. It turned out to be suprisingly hard to at least identify the nature of problem in order to solve it. It was my mistake, the laptop had already preinstalled linux (without a DE though), and i did't try to obtain kernel settings from there because I wanted to start using laptop as fast as possible, so I deleted everything from hard drive while installing gentoo. Don't repeat that, because I lost several days trying to figure out how to get rid of touchpad issue.

So here I will place key moments about setting up this laptop hardware that I couldn't find anywhere in net. Please also note that I'm mainly a programmer, not a hardware or linux internals specialist, so most of this was obtained through experimenting with kernel settings and there may be better configuration or I could have missed something important.

First of all, to turn on this touchpad kernel drivers you have to enable hid_multitouch and designware i2c. To do that enable first intel low power subsystem (CONFIG_X86_INTEL_LPSS, CONFIG_I2C_DESIGNWARE_PLATFORM, CONFIG_I2C_DESIGNWARE_PCI, CONFIG_I2C_HID). I also turned off raw hid access, don't know if it's important though.

Turn off everything in Device Drivers / Input device support / Mice as this is not an elantech or synaptics touchpad. In Device Drivers / I2C support / I2C support / I2C Hardware Bus support turn off everything except Synopsys DesignWare Platform and Synopsys DesignWare PCI.

Next go to Device Drivers / Serial ATA and Parallel ATA drivers (libata) and turn off ATA SFF support. Also turn off all raid drivers (CONFIG_MD). For some reason this lead to touchpad problems, probably because of close addresses of sata contoller and smbus. Also turn on only ACPI Processor P-States driver(CONFIG_X86_ACPI_CPUFREQ) and don't turn on Intel P states, Intel idle or Intel PowerClamp driver - this leads to touchpad issue when GPU is overheated and does throttling (not absolutely sure about all of them, you can test it yourself if you managed to get stable touchpad behaviour).

In Device Drivers / I2C support / I2C support :
Code:

-*- I2C support
<M>   I2C device interface
< >   I2C bus multiplexing support
[*]   Autoselect pertinent helper modules
      I2C Hardware Bus support  --->
< >   I2C/SMBus Test Stub
[ ]   I2C slave support


The rest of hardware is relatively easy to setup, though I think it's better to turn off everything except CONFIG_R8169 in Ethernet driver support and everything except Atheros Wireless Cards in Wireless LAN. Remember to setup CONFIG_MMC_REALTEK_USB, CONFIG_MFD_RTSX_USB and LPC_ICH. MEI and MEI_ME works ok too. In USB Host Controller Drivers enable USB 2.0 (with suboptions), 3.0, Generic EHCI driver, CONFIG_USB_OHCI_HCD and CONFIG_USB_OHCI_HCD_PCI only. Turn on CONFIG_USB_DYNAMIC_MINORS. Turn on CONFIG_GPIO_LYNXPOINT. In addition to usual intel hda kernel drivers turn on CONFIG_SND_SOC_INTEL_SST, CONFIG_SND_SOC_INTEL_HASWELL_MACH, CONFIG_SND_SIMPLE_CARD and codecs from nearby submenu. Turn on kvm. Select Generic-x86-64 as procesor family (CONFIG_GENERIC_CPU).
Full list of modules can be found at the end of this post, so take a look at it. Kernel drivers for every device can be found in lspci -v output.

With this kernel command line, touchpad is really stable and doesn't react to pressing near it on my laptop:
i915.nuclear_pageflip=Y i915.enable_rc6=1 i915.enable_fbc=1 i915.lvds_use_ssc=0 i915.enable_ips=0 i915.modeset=1 i915.lvds_channel_mode=2
I also noticed that after glitching touchpad tends to keep this behaviour for some time even with good settings.

mcelog complains about Cache level-2 error after suspend / resume, looks like not affecting anything though. I also had some troubles with laptop mode tools trying to disable ethernet, so I disabled all it's modules except hard drive power save. I also turned off acpid.

Hope I didn't forget something important and I'm still experimenting. Feedback is appreciated.

EDIT: Kernel configuration obtained by further experimenting can be found later in this thread, and command line turned out to be different. See this message.

Can you post full dmesg output and your kernel .config and would be great to see dmidecode output

Hi, hypercube2015!

Maybe It can be helpful Archwiki:Acer Aspire V3-371 and Archwiki:Buttonless touchpads (aka ClickPads)

I'm a bit new to where is better to place all of this - they are big.

EDIT: Here is 4.0.9 kernel config (had more time to test - works very nice for me):

I didn't have a problem with setting it up to make linux work, but without solving touchpad issue (and I don't see this solution in arch wiki) I believe there is interference between hard drive and touchpad (and probably video subsystem), and I had hdd failure once (had to reboot) before I solved the problem. Don't know if it's the case when touchpad is off. Anyway, thanks.

I have an Aspire V3 working ( not completely sure about the '371' part, it is a intel core i5), with the touchpad working as well. No problems with the touchpad here.
What issue do you have with the touchpad ?

Alex.


( if any, I have problems with the usb-mouse on certain ports on resume from suspend...).

I already install new kernel but didn't test it properly yet. I will correct kernel settings soon. You can turn off iscsi related options yourself though.

My issue was that touchpad made crazy jumps all over the screen until turned off with Fn+F7. After some time after reenabling it did it again.
Also, which usb options in kernel do you have?

On a side note: If they are too big, you can use wgetpaste:https://wiki.gentoo.org/wiki/Wgetpaste

For example,
Code:
wgetpaste /var/log/Xorg.0.log
uploades the file and give an url to watch the content....

Hypercube,

Some more infoabout my setup: I am not sure what kind of touchpad I have. I do have 'synaptics' in my make.conf:
Code:
INPUT_DEVICES="evdev synaptics"



Also, xf86-input-synaptics installed:
Code:

alex@Aspire /usr/src/ $ eix xf86-input-synaptics

I have it too, but it's userland tool, not a kernel driver. You can detect kernel driver by analysing lsmod output, if it's compiled as module, of course.

kernel help wrote:
CONFIG_USB_OHCI_HCD:
The Open Host Controller Interface (OHCI) is a standard for accessing
USB 1.1 host controller hardware. It does more in hardware than Intel's
UHCI specification. If your USB host controller follows the OHCI spec,
say Y. On most non-x86 systems, and on x86 hardware that's not using a
USB controller from Intel or VIA, this is appropriate. If your host
controller doesn't use PCI, this is probably appropriate. For a PCI
based system where you're not sure, the "lspci -v" entry will list the
right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.

You can do some experiments with trying to find minimal necessary set of usb drivers by loading and unloading their modules.

Thanks,

I agree, I probably do not have the minimal set . I started with Genkernel, and added some options along the way. However, the touchpad works as expected.
So, so far, I didn't have the time to start 'removing' options from the kernel to see if it still works :-)

Alex.

Alex.

You can use modprobe -r to unload usb modules instead of editing kernel config. When you know exact set (or at least module causing problem) you can edit kernel config. Or you can remove all of them and add one by one manually until problem reappear.

I already install new kernel but didn't test it properly yet. I will correct kernel settings soon. You can turn off iscsi related options yourself though.
Seems like CONFIG_I2C_DESIGNWARE_PCI is really needed. Corrected first post.
P.S. Also enabled Acer WMI in 4.1.12, everything is ok so far, when I'm sure it's totally ok I will post kernel and dmesg.

To make long story short:

here is kernel configuration: https://bpaste.net/show/411cabe1ac31 (to make bluetooth work you need firmware)
here is dmesg: https://bpaste.net/show/23204330d1e4
here is lsmod: https://bpaste.net/show/5b91bbd1749a
here is lspci -vnn: https://bpaste.net/show/8386f84fc6ae
kernel command line: i8042.nopnp psmouse.proto=imps psmouse.rate=40
(psmouse.proto=exps works too)

CONFIG_X86_INTEL_LPSS, CONFIG_I2C_DESIGNWARE_PLATFORM, CONFIG_I2C_DESIGNWARE_PCI should be turned off.

here is options from /etc/modprobe.d/alsa.conf (it's important to correctly set up sound card, https://wiki.gentoo.org/wiki/ALSA):
Code:
...
# Set this to the correct number of cards. (probably 2 should be enough)
options snd cards_limit=4
options snd-hda-intel id=PCH index=0
options snd-hda-intel id=HDMI index=1

Also, disable automute in kmix if you use it.

here is /etc/X11/xorg.conf.d/20-intel.conf:
Code:

Section "Device"
        Identifier      "Device0"
        Driver          "intel"
        Option          "AccelMethod"           "sna"
        Option "TearFree"    "true"
        Option "BackingStore" "false"
        Option "SaveUnders" "off"
EndSection


With this configuration there is no way to make touchpad glitch. No freeze after suspend to ram too.

Tested under Xfce and Xfce with kwin --replace and kde.

Another option is to edit driver kernel sources (/usr/src/linux/drivers/input/mouse/psmouse-base.c) to enable synaptics relative protocol. You'll have to change several lines in psmouse_extensions function.
Change these lines
Code:
         if (IS_ENABLED(CONFIG_MOUSE_PS2_SYNAPTICS) &&
             (!set_properties || synaptics_init(psmouse) == 0)) {
            return PSMOUSE_SYNAPTICS;
         }


to
Code:
         if (IS_ENABLED(CONFIG_MOUSE_PS2_SYNAPTICS) &&
             (!set_properties || synaptics_init_relative(psmouse) == 0)) {
            return PSMOUSE_SYNAPTICS_RELATIVE;
         }


and use psmouse.proto=any instead of imps in kernel command line.

Behaves a bit better than imps, no false clicks, but is not recognized by synclient and there are no taps or two finger scrolling. I also tested case with synaptics relative protocol and not disabling gestures (commented several lines in synaptics.c), but false clicks are still present.

Please note that I'm neither hardware specialist nor manufacturer, so use at your own risk.

P.S. The problem for me was that psmouse didn't autoload, while designware platform + hid_multitouch loaded and touchpad was working. But this solution isn't stable.

Some time have passed, and I figured out some things about my laptop. First of all, the laptop has not so slow video card, but it was overheating really fast even in sauerbraten (on some maps) and warzone2100 (at 1920x1080) up to 95°C, after that throttling strongly lowered fps for some time (and, depending on the kernel config thermal protection could be activated). The solution is very simple, but not obvious.
I placed this in /etc/local.d/brightness.start and in the wakeup acpi handler.

This handler starts when resuming from suspend. To have this script install laptop_mode_tools, no need to start it though.
Code:
echo -n 1 > /sys/class/powercap/intel-rapl\:0\:0/enabled
echo -n 1 > /sys/class/powercap/intel-rapl\:0\:1/enabled
echo -n 1 > /sys/class/powercap/intel-rapl\:0\:2/enabled


UPDATE: Later I noticed that turning rapl for every device in package makes laptop run at min performance, still it prevents overheating.

With rapl enabled games run much better. I also tested this solution on my old lenovo thinkpad e130 - and it's working fine there too.
You may want to turn off plasma transparency effect as it somehow affects temperature in games even if compositing is blocked by application rules (but effects are not turned off completely).

Touchpad is still making tricks on unmodified synaptics driver, but overall behaviour is much better, it's not jumping weirdly all over the screen any more.

UPDATE: MEI_ME does not complain about hbm anymore, and x2apic is on. For some reason P-State always show that processor is always at 800Mhz, if you don't like it you can use ACPI P-States (a bit less efficient) intead of Intel P-States driver.
Message "BAR 6 has bogus alignment" is solved by CONFIG_PCI_REALLOC_ENABLE_AUTO and CONFIG_PCI_IOV.

Here is kernel 4.4.6 config, dmesg and lsmod output.

Turn on DRI3:
/etc/X11/xorg.cong.d/20-intel.conf
Code:
Section "Device"
        Identifier      "Device0"
        Driver          "intel"
        Option          "AccelMethod"           "sna"
        Option          "DRI"    "3"
        Option          "TearFree"    "true"
        Option          "Tiling"                "false"
        Option          "BackingStore" "false"
EndSection


Kernel command line:
Code:
i8042.nopnp psmouse.proto=any psmouse.rate=40 i915.use_mmio_flip=1


Now everything seems to work fine except touchpad, it is inconvenient to reenable it all the time, but I don't use it often. Seems to be common problem for this laptop solved by BIOS update: http://community.acer.com/t5/V-and-VN-Series-Laptops/Aspire-V3-371-Touchpad-Freezing/td-p/293690.
