ASUE120A Touch pad not detected

kurohi · n00b Joined: 03 Jul 2012 Posts: 12

Hello everyone.

Have been trying for days to get my touchpad to work to no avail.
It does work if I boot the system with a systemrescue liveCD. Which gave me some insights to where to look, but still could make it.
Tried following the tutorial here: https://forums.gentoo.org/viewtopic-p-8692426.html#8692426 but still did not work

Here are the links for the hw-probe of the original computer and the systemrescue
- Installed environment: https://linux-hardware.org/?probe=04f5858a30
- Systemrescue: https://linux-hardware.org/?probe=d17d5e5310

Here is also the .config used (still need some cleaning as I activated everything remotely related to touchpads):
https://dpaste.com/C67XEG2H6

The strangest part is that I am getting a device on /sys/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-13/ with the name i2c-ASUE120A:00 but still no touchpad detected.

Any help will be greatly appreciated, as I cant think of anything else to try.
Thanks

kurohi,

I'm late to this particular party.

Your pastebins are gone :(.

Can you post/pastebin both the working and non-working.

@pietinger Oddly enough it is the same shortcut as the Thinkpad for touchpad locking/unlocking. On windows and on the systemrescue, it did manage to lock and unlock the touchpad.
Tried leaving it unlocked and rebooting into the installed system, but was the same result.

Not late at all, grab a seat and drinks are at the bar

And thanks in advance for the help.
I am reposting the pastbins for the installed system and systemrescue:

-Installed system:
kernel configs: http://dpaste.com/CVEXYTMX3
lspci -nnk: http://dpaste.com/7Y83L4LAP
dmesg: http://dpaste.com/D28TW62A9
lsmod: http://dpaste.com/H5BFJ5S8J

-Systemrescue (where the touchpad worked):
kernel configs: http://dpaste.com/8DY5QYGT6
lspci -nnk: http://dpaste.com/7M4PN8B95
dmesg: http://dpaste.com/F85S5G6CF
lsmod: http://dpaste.com/AUMVW8H2E

Added the lsmod as well as it might give some extra idea of what is going on.

As I said in my first post, your kernel configuration looks good ... but MAYBE you dont use this configuration. Are you sure you have booted the correct kernel ? Check with

Hi pietinger,

Thanks for the hints. I checked with the dmesg | grep "Linux version", but the version was correct and it was the kernel I tried building a few hours ago.
I haven't tried using

Tired going though the tutorials for microcodes for intel.
It helped me fixing a minor graphical glitch that I was having with nvidia, where the cursor would randomly go back a few characters, although the input was unaffected.
It was minor because, if you ignore what was on the screen, typing flowed as usual.

However, the touchpad problem still persists.
This is how the kernel variable is looking now.

[code]
CONFIG_EXTRA_FIRMWARE="i915/adlp_dmc_ver2_14.bin i915/adlp_guc_62.0.3.bin"
[/code]

The actual microcode is being loaded with dracut by including the --early-microcode flag when generating the a new initramfs

Following pietinger's hint, I am getting with the habit of checking if the newly built kernel is indeed the right one with uname -a. Thanks again

kurohi,

Those microcodes are GPU related. They will do nothing for your touchpad.
Do you need.

NeddySeagon,

I have checked on the kernel configuration and the flag you pointed was being compiled in the kernel.
Might be worth trying to build it as a module.

Here are all the ASUS related kernel flags

[code]
ag asus .config
2254:# CONFIG_USB_PEGASUS is not set
2489:# CONFIG_TABLET_USB_PEGASUS is not set
3261:# CONFIG_SENSORS_ASUS_WMI is not set
3262:# CONFIG_SENSORS_ASUS_WMI_EC is not set
4530:CONFIG_HID_ASUS=m
5150:CONFIG_ASUS_LAPTOP=y
5151:CONFIG_ASUS_WIRELESS=m
5152:CONFIG_ASUS_WMI=y
5153:CONFIG_ASUS_NB_WMI=y
5154:# CONFIG_ASUS_TF103C_DOCK is not set
[/code]

I tried compiling without modules, but it still did not work.
Not sure why, but had some trouble reverting back.
Compiling with all modules as static made it so I could not use the wifi card.

This is the dmesg from the kernel with all modules as static: http://dpaste.com/4EGNLBEV5
This is the dmesg with the kernel as before (in case the partebin disappeared): http://dpaste.com/GL9W2GQK2

Delete this from your kernel command line and try again:

Ah, got it. For now will leave it as it is as it is just a minor problem that I can get back with a quick recompilation of the kernel.

Following the last comment, I removed the
[code]
i8042.noloop i8042.nomux i8042.nopnp i8042.reset
[/code]

Got those lines from the tutorial for touchpads. It worked for removing an error on dmesg but not for getting the touchpad to work
from grub, recompiled the kernel with the modules as static and got the dmesg: http://dpaste.com/ESLE2C9XK

Ok, we have the problem that intel-lpss-pci is not loaded. Maybe you have a synopsis designware controller. I dont know if you have enabled this (because I cannot read your kernel config now), but if not try this:

kurohi · n00b Joined: 03 Jul 2012 Posts: 12

pietinger,
Sorry for the late response. It was already late here.
I just checked the kernel config and the pointed configuration was already marked as static.
Will try to change the intel-lpss-pci and i2c-designware options as static and try again. Trying to manually load those modules did nothing

Yup. Putting the i2c-designware as static did not work either.
The path /sys/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-12/i2c-ASUE120A:00/ is still being created, but without the touchpad after the i2c-ASUE120A:00 folder.

Will go over the internet and find a way to increase the "verboseness" of i2c-designware to see if I can get any hints from there.

@luna80 had a problem with the touchpad of an Ideapad with an interesting result:

It worked until linux 5.10.100; with any newer version it didnt work anymore ... :-(

pietinger · Posted: Tue Apr 05, 2022 1:07 am Post subject:

kurohi,

do you know the moment when you think it must work because it is all correct configured and it doesnt ? Then you will have crazy thoughts ... so only an intimate question: Do you have edited (once or betimes) your .config manually ?

If yes, please read this article from our @NeddySeagoon:

https://forums.gentoo.org/viewtopic-p-8686380.html#8686380

If no, we have to search onwards ... ;-)

pietinger,

had some bad experiences before when I tried to edit the config file manually so never again

And to top that, forgot to backup the old one. Now I only use the menuconfig tool and backup the file once I confirm the kernel is stable

Guess the quest for the elusive touchpad continues, lol.
Will try to go over the linux hardware probes with similar setup and see which modules they are using.
