lenovo legion y740 - trackpad

#1 Post by negrao »

Hi

I just got a lenovo legion y740 15" which was launched in February so it is very recent. I have everything working except the trackpad. I'm running debian stable with kernel 4.19 from backports (which was needed to get wifi working).
I was wondering if it is possible to get the trackpad working or do I need to wait for a newer kernel version ?

Thanks,
Miguel Negrão

Tried installing the 4.20 kernel from https://build.opensuse.org/project/show ... re-support.

I installed these deb files:

Code: Select all

linux-headers-4.20.0-1-amd64_4.20-1~obs_amd64.deb
linux-headers-4.20.0-1-common_4.20-1~obs_all.deb
linux-image-4.20.0-1-amd64-unsigned_4.20-1~obs_amd64.deb
linux-kbuild-4.20_4.20-1~obs_amd64.deb
The kernel installed correctly although there was on problem with module which is quite strange. During the installation of the 4.20 kernel it is apparently trying to build something in /lib/modules/4.19.0-0.bpo.2-amd64/ ?

Code: Select all

do you have the below installed (nevermind the version, do you have the package)

Code: Select all

dpkg -l | grep synaptics
ii  xserver-xorg-input-synaptics                                1.9.1-1                              amd64        Synaptics TouchPad driver for X.Org server
and if so have you setup an xorg config for it?

Well, that's weird. Apparently, you have some alsa-firewire dkms package I've never seen before, and dkms packages are outside of the kernel and are supposed to rebuild automatically when a new kernel or kernel update is installed. I don't know where yours came from, since I and nobody else has reported that.

Is your laptop Nvidia-only, or do you have the integrated Intel UHD 630 GPU disabled in the BIOS? I thought that that machine would be using the switchable Optimus setup. That Intel GPU really requires a backported Mesa to work correctly (which is also in my OBS repo or stretch-backports). The machine also needs the latest firmware-misc-nonfree to really work correctly, but you must have found that already for firmware-iwlwifi, since you have the wi-fi working.

About the touchpad, it seems similar to other Lenovos with Elan touchpads with ACPI IDs that don't appear in the kernel driver. Can you run

Code: Select all

dmesg | grep i2c
and

Code: Select all

dmesg | grep elan
to see if the kernel can at least see and show the touchpad's ID?

Yes, I have xserver-xorg-input-synaptics installed:

Code: Select all

dpkg -l | grep synaptics
ii  xserver-xorg-input-synaptics                                     1.9.0-1+b1                                  amd64        Synaptics TouchPad driver for X.Org server
But in https://wiki.debian.org/SynapticsTouchpad it says I should find out what type of trackpad I have and it doesn't find anything:
egrep -i 'synap|alps|etps|elan' /proc/bus/input/devices
displays nothing...

I have not setup a an xorg config for it.

Also the following displays nothing:
sudo dmesg | grep i2c
sudo dmesg | grep elan

Ah, you're right ! I had installed that module manually from https://github.com/takaswie/snd-firewire-improve. I wanted to use my MOTU sound card directly with ALSA, without using ffado (in my previous machine), but that didn't work and I forgot to uninstall. I have uninstalled that module now.

It should have, I'm actually not totally sure. In the firmware setup menu there is an option to chose between "switchable graphics" and "discrete graphics". It came from factory in "discrete graphics" and I still haven't changed it from that. I installed the nvidia proprietary driver, and everything is running fine graphics wise. Even before installing the nvidia driver I was able to use gnome using what I suppose is a basic driver (because I don't think my version of the nouveau driver supports the RTX2060 yet).

My version of firmware-iwlwifi didn't have the firmware for my wifi card (9650) so I installed the firmware file manually from the intel website. After updating to 4.19 kernel the wifi started working.

Well, the firmware-iwlwifi in backports and in debian testing does support that 9560 chipset. If you do use a new kernel, you should update all firmware from backports to match. Maybe Lenovo or Windows could tell you what exactly the trackpad is, because I'm stumped at the moment.

Yes, your machine has the Intel GPU turned off. Most users have it on to get better battery life, lower heat,maybe a faster CPU, and then use some kind of switcher like Bumblebee to use the discrete card only for demanding 3D rendering, such as in graphic programs and games.

When I turn on the Nvidia GPU on my MSI GP63, which has the same i7-8750H CPU, I do see my maximum sustained CPU speed drop from 3.6 to 3.2 or even 2.8 GHz, apparently because they are sharing the power bus. There are some advanced power tweaks I could do if I get into the secret advanced MSI BIOS power settings to fool it that there's more power (IM slope), but I'm pretty good with it now, especially since I undervolt it with iuvolt to reduce thermal throttling already without much hassle.

Ok, I have updated the firmware packages to the versions in backports and removed the manually installed firmware file. Wireless is still working.

Code: Select all

ii  firmware-iwlwifi                                                 20180825+dfsg-1~bpo9+1                      all          Binary firmware for Intel Wireless cards
ii  firmware-linux-free                                              3.4                                         all          Binary firmware for various drivers in the Linux kernel
ii  firmware-linux-nonfree                                           20180825+dfsg-1~bpo9+1                      all          Binary firmware for various drivers in the Linux kernel (meta-package)

ii  firmware-realtek                                                 20180825+dfsg-1~bpo9+1                      all          Binary firmware for Realtek wired/wifi/BT adapters
I've looked in Windows 10 to see how the trackpad is reported, it shows:

Code: Select all

Device I2C HID

Hardware ID:

HID\VEN_SYNA&DEV_7DB5&Col02
HID\SYNA7DB5&Col02
HID\*SYNA7DB5&Col02
HID\VID_06CB&UP:000D_U:0005
HID_DEVICE_UP:000D_U:0005
HID_DEVICE
So it seems it is synaptics ? I've see with google other people with a computer with same trackpad and it is reported with xinput...

I would prefer actually to run all programs that run on the laptop screen with the intel card and only run the nvidia for anything over hdmi or dp. Will investigate how to do that.
Windows reports that the intel graphics card (after activating in firmware) is Intel(R) UHD Graphics 630.
Just to check what would happen I tried booting debian with the intel card activated, without installing bumblebee, but it got stuck in grub. Nothing appears after "loading ramdisk". I wonder if it is possible to use just the intel card with no switching ? I tried in the kernel parameters nvidia.modeset=0 but that didn't work. I see that nvidia driver 415.27 is now already in experimental, I will switch to that and then see if I can install bumblebee.

Thanks for all the help so far.

Usually, if you turn on the switchable graphics, they take precedence, so the Intel card should be automatically detected. Your Lenovo may be quirky if they turned it off by default, even for Windows users, however. Normally the newer kernel will get your UHD 630 working with software acceleration, then you need to install a newer Mesa (libgl1-mesa-dri and libgl1-mesa-glx) from backports to get the hardware acceleration.

Could you try booting an MX 18.1 Linux Live USB? That has a 4.19 kernel and all the backports already on a Stretch base...I help develop it and wonder if it will still have the same trouble booting.

Try

Code: Select all

nomodeset nvidia.modeset=0
Both are needed for discrete cards.

Hi

With the image MX-18.1_x64.iso and laptop firmware switched to switchable graphics the system boots fine, I can login in the graphical manager. The intel card appears in lspci. It does not however detect a second screen when I connect it via DP. In any case I believe nouveau does not yet support the RTX 2060 in kernel 4.19 or 4.20. The touchpad is still not detected, and does not appear in xinput or dmesg.

tryed booting my debian system with ' nomodeset nvidia.modeset=0' but I still get stuck in grub. I suppose to troubleshoot I should uninstall the nvidia driver, I will try that at some point. My / partition is inside luks, so a luks password is asked at start. I wonder if the stuck screen is because it is waiting to unlock the partition. I did try entering the password but nothing happened.

Thanks again !
Miguel

Regarding the original question, the trackpad, given that I now know the touchpad model (SYNA7DB5) and that it is not detected by the latest kernels, what should be my next steps ? Should I file a bug report, and if so on which package ?

Regarding the GPU, I have uninstalled the nvidia driver, and when I boot with intel card turned on, it does get stuck in grub, but once I enter my LUKS password blindly, after some seconds, the dmesg log appears, and the boot proceeds normally. The system reports the intel card being in use. The nouveau drivers reports it doesn't know this graphics card.
With the NVIDIA drivers installed, if I enter the password blindly I never exit the grub screen and I have to force shutdown the computer. Using journalctl -b -1 I can see that actually the system seems to boot fine, it just never shows anything on the screen, it stays in the grub screen. This indicates that the problem is related with the NVIDIA drivers, and possibly an interaction with LUKS. Since nouveau still doesn't support my card (NVIDIA RTX 2060) I cannot use it at this moment, in order to use the DP or HDMI ports.

Thanks

Hi again,

I've now manage to see that the kernel is at least detecting the touchpad:

Code: Select all

ls /sys/bus/acpi/devices/SY*

/sys/bus/acpi/devices/SYNA7DB5:00:
hid  modalias  path  power  status  subsystem  uevent

/sys/bus/acpi/devices/SYNA7DB5:01:
adr  hid  modalias  path  physical_node  power	status	subsystem  uevent  uid
How can I use this information to determine why it is not working in gnome ?

Thanks
Miguel

The Nvidia 410.104 now in testing and stretch-backports also supports your Nvidia 20XX card now. I have it on a Stretch base because I need it for 5.0 Liquorix kernel backports, which I also have in an OBS repo: https://build.opensuse.org/project/show ... r:codelite

The 410.104 driver doesn't support the RTX2060. I think the first driver that supports it is the 415.27.

Code: Select all

nvidia-detect 
Detected NVIDIA GPUs:
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation TU106M [GeForce RTX 2060 Mobile] [10de:1f51] (rev a1)

Checking card:  NVIDIA Corporation TU106M [GeForce RTX 2060 Mobile] (rev a1)
Uh oh. Your card is not supported by any driver version up to 410.104.
A newer driver may add support for your card.
Newer driver releases may be available in backports, unstable or experimental.
Best,
Miguel Negrão
