Re: Does Fibocom L850-Gl work on Linux after the 1.37 BIOS update?

As mentioned before. I have Latitude 5501 (Freshly dismanteled it today), with ubuntu 18.04 pre-installed. It has Fibocom L850-GL modem in. I has BIOS settings to choose wether this slot will be used as PCI-E or USB. I put in my SIM card, turn on laptop and I click connect to broadband and it just works (http://tiny.cc/3pmfcz).

 

This is just pure lazness from Lenovo side. Its not even Fibocom failt for not issuing drivers. They could just implement same thing or just whitelist L830-BE for all devices untill tehere are drivers.

 

Lenovo stated that they do not officially support ubuntu and it is true. They put on their homepage that Ubuntu will be pre-installed just to trigger more marketing (Just google "Thinkpad P series Ubuntu" and you will find a lot of them (All lies).

Re: Linux status of Fibocom L850-Gl

Hi,

 

Been happily using my X1 C6 w/ WWAN via EM7455 with the tweak to get it to initialize usb slowly.  (Thanks for all the tips, especially @intelfx! )

 

Does anyone know if this configuration would still work with the latest BIOS 1.41 ?

 

(or, if anyone has since gotten the Fibocom L850 to actually work in linux.. sounds like no still.. )

 

Thanks!

Yep, the hack still works with the latest firmware updates applied. As for L850, I'm not aware of any attempts to implement a PCIe driver for it.

Re: Linux status of Fibocom L850-Gl

Hi,

 

Are there any updates on this? Our company is a linux shop and we love Thinkpad X1 carbon laptops but need WWAN capability to justify further purchases.

 

Thanks in advance for any information!

Everything we know is summed up in the reply directly above yours.

Re: Linux status of Fibocom L850-Gl

Hi,

Funnily enough I was looking into this item just this morning.

Brief summary: Lenovo is working with the chip vendor to get a linux driver for this - so it is in progress but unfortunately I don't have an ETA. 

I'll see if I can find out when support will be available.

Lenovo don't have to work with chip vendor. Lenovo only need to  add Fibocom L850GL to USB whitelist (yes! L850GL is on the black list of USB port).

 

Plus, so called "chip vendor" does not exist any more. The exitre devision was sold to Apple. Another trick to let you pay for nothing.

Re: Linux status of Fibocom L850-Gl

@Mark, kudos to you for stepping out as a first Lenovo Employee in this thread. Please do yourself and Lenovo a favor and stick to your promises. As @debao already wrote you guys just need to remove the blacklist. Can you please get us an update what's going on in this direction at Lenovo? Can you open a case to discuss that internally?

Re: Linux status of Fibocom L850-Gl

It is obvious that the group of people interested in a working Fibocom L850-GL (and possibly L860-GL) WWAN module under Linux, are many. @Lenovo, do you read?

 

@all, let's concentrate efforts in one thread.

 

In overview, the problem and a proposed solution:

 

 

References in the Lenovo fora:

 

  1. The current thread Linux-status-of-Fibocom-L850-Gl
  2. X1C-gen-6-Fibocom-L850-GL-Ubuntu-18-04
  3. Linux-support-for-WWAN-LTE-L850-GL-on-T580-T480
  4. thinkpad-x1-7th-generation-ubuntu-19-04-linux-learnings (generic "Linux" interest)

 

Elsewhere:

 

  1. Fibocom L850-GL installation on Ubuntu 18.04 in "askubuntu" stackexchange

Re: Linux status of Fibocom L850-Gl

Thanks @NikosAlexandris for gathering all that information in one spot - it's really helpful.

 

As I found out this morning from the driver team (and your link to the overview also mentions) on our boards the device is connected to PCIe and not to USB, so fixing the USB blacklist is not the solution.

 

I'm digging to find out more - there was some confusion when I asked about this item previously as to the status and I really want to make sure I give accurate information so please bear with me and I'll see if I can figure out what is happening internally and (hopefully!) what our plans are to fix it.
