Re: Linux on the ThinkPad X1 Yoga (3rd Gen)

Sure.

I have not done an exhaustive testing but here goes (if there is something specific you want to know about let me know):

I'm running Debian 9 stable XFCE dersktop

 

mouse pad - works out of box

track ball -works out of box

stylus - works out of box

touchscreen - works out of box

suspend - works out of box

hibernate - not tested

wireless - works with minimal effort** ( had to locate some ucode files as I recall)

Thunderbolt - works out of box

camera - works out of box

rotation - works with some effort ** ( can get auto rotation to work but not synced with mouse/stylus (so screen changes but mouse does not, what worked on my last lenovo didn't this time and haven't had the time to dig in), have a manual script for changing rotation and stylus/mouse for "tent" and "side" modes as a panel launcher and works fine)

Bluetooth - haven't tried

function keys - all works out of box

HDMI port - works out of box

cpu scaling - works through superuser

sound - works out of box

 

Battery - last a good 8+ hours (never actually timed) under moderate work loads (internet browsing, python, libreoffice, texmaker, etc..)

 

Only issue is some keys get stuck down ('page down' key mostly) when flipping from closed to open, (or switching configs) and I need to tap it to use the keyboard.

 

That's all I can think of off the top of my head, hope it helps.

Re: Linux on the ThinkPad X1 Yoga (3rd Gen)

Thank you. What about:

- Cardreader
- WWAN
- Intel Ethernet Connection
- USB 3.0 xHCI -- does it crash?

Re: Linux on the ThinkPad X1 Yoga (3rd Gen)

I did expect a cardreader (SD) but mine did not have one,
No Ethernet connection (no RJ45/8p9c ports)
Not had a single problem with the USB3.0 (I haven't tested the speed but anecdotally it seems faster than 2.0.)

I don't have the extra wwan, so can't say

Re: Linux on the ThinkPad X1 Yoga (3rd Gen)

Am I correct that all basic functions of X1 Yoga Gen 3 are working under Linux at least under Debian? By Debian, do you include ubuntu and Pop!_OS?

Re: Linux on the ThinkPad X1 Yoga (3rd Gen)

Hi,

 

Yes, that's what I understand.

No fix for S3 sleep state... But at least, they fix the Thunderbolt assist mode brick issue ...

 

Maybe we'll see the S3 sleep state in 6 months. Maybe not.

And still no option to shutdown PCIe lane on wwan to use USB mode on Linux.

 

And this laptop is certified for Ubuntu...

Sorry, I don't know about this issue:
"And still no option to shutdown PCIe lane on wwan to use USB mode on Linux.".

What is it exactly?

Sorry, 

Refer to this : https://forums.lenovo.com/t5/Linux-Discussion/X1C-gen-6-Fibocom-L850-GL-Ubuntu-18-04/td-p/4078413

 

Wwan card in ThinkPad X1 (yoga or not) doesn't have PCIe driver for Linux but does have USB driver. Lenovo could add a bios setting to disable PCIe on this card so Linux could use it with USB interface

Re: Linux on the ThinkPad X1 Yoga (3rd Gen)

So, there is no functional WWAN under Linux?
