Tried both v4.18.3 and v4.18.4 using UKUU. Nothing changed.

Upon first installation and after upgrading kernels my wifi was not working either, but that was fixed by installing proper drivers.

Wifi works with using rtl8821ce drivers found here: https://github.com/tomaspinho/rtl8821ce

As far as touchpad goes, it's still not working on 4.19.0-rc7, after upgrading kernel today.

Wifi does work on Yoga 530-15, but sometimes doesn't after reboot and only another reboot (off/on) helps.

Additionally, rtl8821ce is causing trouble during shutdown. The system freezes once a shutdown is initiated via X (Ubuntu Desktop). Switching to a plain text console does start the shutdown, but also freezes inbetween. According to dmesg, rtl8821ce is causing problems, but the main reason could be the nouveau kernle module.

For Yoga 530-14, Wifi, Touchscreen and Touchpad are not working at all. System often freezes at boot, during work or on shutdown. Finally installed VirtualBox on Windows to use Ubuntu at all.

Found this patch, that will hopefully solve this problem: https://<email address hidden>/msg1793230.html

Found this patch, that will hopefully solve this problem: https://<email address hidden>/msg1793230.html

For now this is how I got touchpad/touchscreen working: https://github.com/Syniurge/i2c-amd-mp2

My model is a Yoga 530-14arr

Thanks to @frilancer for the link in comment 25.
I can confirm that my touchpad/touchscreen are working fine with the module he linked:
https://github.com/Syniurge/i2c-amd-mp2

Therefore my wifi isn't working (tried the driver from https://github.com/tomaspinho/rtl8821ce yet, but doesn't work as stated by @sebastian-willing in comment 23)

(Reposting the workaround for the WiFi I mentioned on Github)

It's actually a bug with the ideapad-laptop driver, wrongly reporting radio devices as hardware-blocked.

Just rmmod or blacklist the ideapad-laptop module and WiFi and Bluetooth will show up and work with this driver:

```bash
sudo modprobe -r ideapad-laptop
```

An entry for the Yoga 530 needs to be added to no_hw_rfkill_list in drivers/platform/x86/ideapad-laptop.c

@Syniurge: Wifi and Bluetooth do work on the 530-15IKB no matter if ideapad-laptop is loaded or not. Try `rfkill` to see the current hard- and softlock state.

Sorry, this was for the Yoga 530-14ARR, I should have specified. And by "Wifi works with this driver", I meant https://github.com/tomaspinho/rtl8821ce

Similar to LP: #1795292?

I am just compiling na fresh vanilla kernel (4.20) and will then try this: https://github.com/Syniurge/i2c-amd-mp2

I am compiling this new kernel, because the repository says, that the dkms on the stock kernel may not work. I tried the installation an indeed, touchpad and touchscreen stayed dead.

I can confirm, that blacklisting ideapad-laptop and installing https://github.com/tomaspinho/rtl8821ce makes wifi/bluetooth work as expected.

But this is a "touchscreen" thread isnt it? :) So lets get this done!

Is there anything i may try to get this working or is there any information that i can give to make diagnosis more easy? I already tried building the kernel from linux-source package matching my version and installing the dkms stuff but had no luck so far. Any guesses?

No you don't need to do anything. I'll update the driver in Ubuntu's kernel.

Please test this kernel out:
https://people.canonical.com/~khfeng/lp1787775/

Thank you very much.

Did you only work on the touchpad-driver or did you also implement the rtl8821ce-driver?

Only touchpad.

Tried it today. Couldn't load the kernel with ubuntu-16.04.4 on Yoga 530-14arr.

Might have fucked something up. Booting through recovery worked but then the trackpad didn't work.

Please attach dmesg, thanks!

I can confirm kernel in #34 works for Latitude 5495 which also uses AMDI0011. Please try the kernel out so I can update the driver.

Hey Kai-Heng Feng, thank you so much. This just works nice! I would like to buy you a beer!

As I said, I can't boot without recovery mode.

@hookedbehemoth: Not 100% sure but it looks like you booted the old kernel (where the driver was builtin) with the new modules.

[ 3.303452] Modules linked in: hid_sensor_custom(E) hid_sensor_hub(E) wacom(E+) chash(E) i2c_algo_bit(E) ttm(E) drm_kms_helper(E) syscopyarea(E) hid_roccat_savu(E) sysfillrect(E) hid_roccat(E) hid_roccat_common(E) sysimgblt(E) fb_sys_fops(E) nvme(E) usbhid(E) drm(E) nvme_core(E) wmi(E) i2c_hid(E) video(E) hid(E)
[ 3.321326] Call Trace:
[ 3.322515] amd_mp2_pci_work+0xa1/0x110

amd_mp2_pci_work doesn't exist anymore in the latest versions of the driver, and i2c_amd_mp2 isn't listed in the list of modules linked in.

But the module containing the newer driver doesn't get loaded either because of symbols missing in kernels older than 4.19:

[ 6.263647] i2c_amd_mp2: Unknown symbol i2c_get_dma_safe_msg_buf (err 0)
[ 6.292760] i2c_amd_mp2: Unknown symbol i2c_put_dma_safe_msg_buf (err 0)

I'm surprised that it worked at all for Kai and Stephan. The patch needs a few changes in order to be applied to older kernels, I forgot to mention it.

I tried installing the kernel with a fresh install of ubuntu-16.04.4 because it was the only version with a kernel lower then 4.15xx that I had on my system.

I tried installing over the ubuntu GUI but that was very strange. As I wrote it will not boot at all. If I boot recovery It will work and that's where the dmesg comes from.

That's strange then, maybe the old driver is still builtin in https://people.canonical.com/~khfeng/lp1787775/.

Kai is waiting for the driver to be accepted by Linux's maintainers before applying it to Ubuntu's kernel.

If you want to get the touchpad working beforehand on your Yoga 530-14ARR, I suggest installing Ubuntu 18.04, this kernel:

  https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19.9/

Then the i2c-amd-mp2 driver in DKMS version with the following commands:

  sudo apt install build-essential dkms
  git clone https://github.com/Syniurge/i2c-amd-mp2.git
  cd i2c-amd-mp2
  sudo ./dkms-install.sh

Reboot and the touchpad and touchscreen should work.

> Kai is waiting for the driver to be accepted by Linux's maintainers before applying it to Ubuntu's kernel.

(I meant the new driver, which works with the Yoga 530. And it should be soon, the maintainer is waiting for someone from AMD to acknowledge or review the submitted patch.)

Thanks a lot. Works like a charm.

[ 0.000000] Linux version 4.15.0-42-generic (buildd@lgw01-amd64-023)

This mean the kernel is built by Ubuntu's official builder, so it's expected not to work.

Can confirm that kernel from #34 works with touchpad and touchscreen on the flex-6-14arr, but will only boot from recovery mode.

I have tried using the the i2c-amd-mp2 driver fix in 4.18.0-13-generic with no luck.

I'm using a Ideapad 530s-14ARR, Linux version 5.0.3-050003-generic, Ubuntu 18.04.

Followed #44's steps to install the i2c-amd-mp2 driver and now my touchpad works.

The driver has landed to upstream, I'll build a test kernel to let everyone verify.

I built kernels for Bionic, Cosmic and Disco, please test:
https://people.canonical.com/~khfeng/lp1787775/

And please remove the MP2 DKMS to really test the kernel.

tested on cosmic without mp2 dmks module and tochpad and screen are working fine :)

Now only the wifi is with additional module and the screen flicker I have is left for me.

Should I file a bug for this screen issue?
https://askubuntu.com/questions/1124286/cosmic-vega-8-screen-flicker-glitches

I can also confirm the fix is working great for touchpad and touchscreen on my YOGA-530-14ARR (AMD® Ryzen 3 2200u with radeon vega mobile gfx × 4 ).

-- Fixing the wifi issue for three days until it finally worked, stumbled upon this bug ticket today, downloaded the fix - and it works. I am amazed and grateful for the great work. Thanks --

Just as a usage report after a while:

I mostly have to reboot the device after first boot again, as the recognition of the two/three finger gestures isn't working correctly aswell as the scrolling.
It appears then that after using such gestures, the mouse hangs in the gesture mode. E.g. after scrolling with two fingers it stays in scroll mode even with only one finger until I scroll again.

If I reboot the device again, this behaviour is fixed for the uptime.

Apart from that: I had more and more problems, that my ssd out of a sudden disappeard from the system. I found the following kernel parameter that fixed it for me:
nvme_core.default_ps_max_latency_us=0

Would be nice to hear if others have these things aswell, or if it's only me.
