Unfortunately, I can't edit the first post anymore. I think the forums might have a time limit for editing posts. Kind of annoying as I'd hoped to be able to keep the first post up to date as this thread progressed...

Re: [Guide] X1 Carbon 7th Generation Ubuntu compatability

This thread (https://forums.lenovo.com/t5/Ubuntu/thinkpad-x1-7th-generation-ubuntu-19-04-linux-learnings/m-p/4494342/highlight/true#M2787) also on the forums suggests installing TLP from a PPA to help with battery issues.

 

I noticed that the TLP version in Ubuntu 19.04 is 1.1, whereas the PPA has the most recent version 1.2.2... version 1.2 added some Thinkpad specific changes so it's worth running the newer version (I can't tell yet if it's making a difference).

 

Here's the PPA with the up-to-date TLP packages (https://launchpad.net/~linrunner/+archive/ubuntu/tlp)

 

Furthermore, there's a new firmware release for the synaptics touchpad that should fix the issue of it sometimes not working when the laptop boots.

 

It can be downloaded here: https://pcsupport.lenovo.com/ca/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x1-carbon-7th-gen-type-20qd-20qe/downloads

under "Mouse, Pen, and Keyboard"

 

The firmware upgrade only runs on Windows however... which is a bit frustrating since the it seems like the only note in the changelog is to fix an issue in Linux.  Hopefully they add the new firmware to the Linux Firmware Vendor Service soon, so we can apply it in Linux.

I upload a hardware probe to linux-hardware.org:

 

https://linux-hardware.org/?probe=c151a85719#Info

 

From the probe you can see that the fingerprint reader is still not recognized, but might be working under the most recent version of libfprint: https://gitlab.freedesktop.org/vincenth/libfprint/issues/1 The T490 has the same fingerprint reader.

 

Also the soundcard has better support in linux 5.2 according to linux-hardware.org.

Hi all,

 

since the hardware is obviously pretty similar, here's a HW probe of my ThinkPad X1 Yoga 4th

https://linux-hardware.org/?probe=dfa35294d9.

 

Same probs (mic, speakers, fingerprint scanner, ...) but apart from that it runs nicely :-)

I tried the latest libfprint without success.

The touchpad works with the latest firmware (I use dual boot to install the firmware)

Hibernation also works.

 

Cheers!

For both the X1C7 and the X1Y4 the sound requires the use of the newer SOF audio drivers generally available in the 5.3 kernel along with some alsa configuration files changes.  Also for the finger print reader there is a firmware update in the works that fixes it for linux along with the latest fprintd libraries I have tested it and it works great just not offically released at this time.

Dave, thanks for the update! Will the SOF driver also work with the standard kernel? I hope you can post some instructions about the required configurations.

Thanks Dave for the update!  Glad to hear fixes are in the works.

 

Do you know if there are plans to submit the trackpad firmware upgrade to the Linux Vendor Firmware Service (for updates via fwupdmgr)?  It's currently only available as an .exe update, but it fixes the intermittent trackpad problems in Linux (or so it says in the firmware changelog).

Can anyone confirm if Bluetooth on the X1C7 on Ubuntu 19.04 is working as expected?  I don't seem to be able to pair any headphones to the laptop anymore, they will connect for a second then revert to disconnected.  They connect fine and are stable on my X1C5 on 19.04.

I just tried bluetooth for the first time on my X1Y4, which has the same hardware. It works. The only difference I see is that I'm using the standard kernel. I am not sure what it really means in this case but your HW probe says "detected" while mine says "works".

Bluetooth in 19.04 worked for me out of the box with the standard kernel (and 5.2.6 from the mainline ppa).  In fact a bluetooth headset is one way to get around the unrecognized internal mic.
