    Upgraded from Ubuntu 19.04 to Ubuntu 19.10 - now laptop freezes after couple minutes

    Hello,

    I recently got a new laptop which sports some very recent hardware, a Lenovo Thinkpad X1 Extreme Gen2. I installed Ubuntu 19.04 on it (dual-boot with the preinstalled Windows 10), motivated by needing newest support.

    Got a whole range of issues on it. Wifi card not detected, Nvidia graphics card not detected, microphone, couldn't even connect a beamer on it. I suspected some driver issues and after Googleing around I figured out the support would be added with newest Linux kernel / Ubuntu release.

    Today I upgraded to Ubuntu 19.10. The system now detects the Wifi card (yay!) but it freezes completely after a couple minutes. Ranging from 2-3 minutes after boot to 20mn. The machine doesn't respond and I need to hard reboot.

    I could try a fresh 19.10 install but I have a priori no guarantee that it would work.


    What do you think is going on? How would I troubleshoot this?


    Thanks,


    EDIT 2019-10-30 : I have narrowed down the issue to incompatibility (seemingly) with the network adapter Intel AX200. In short, my computer freezes completely unless I quickly turn on "airplane mode" at login. See the replies for more infos. It seems to be common, found e.g. this: https://bugzilla.redhat.com/show_bug.cgi?id=1738361

    EDIT 2019-10-30 #2 : Here is the output of the wireless info script: https://paste.ubuntu.com/p/jY9xP3dTVx/

    Though there is no guarantee I think it's worth a try.

    Hi again,

    I didn't reinstall 19.10 yet but I narrowed down the issue. I've seen that my computer does not freezes if I immediately disable the wifi (airplane mode) at boot. So this sounds like an issue with the wifi adapter and/or drivers.

    I see "Intel corporation Device 2723" near the bottom, which sounds awfully like: "we don't know what this is".

    When I was on 19.04 I tried to install IWLWIFI backport drivers following these instructions: https://askubuntu.com/a/1156246 .

    I will be trying to use a fresh Ubuntu 19.10 from a bootable drive, to check whether reinstalling the system would work or not. If it doesn't, what do you suggest?

    In general, if one distribution doesn't work - try another one. There are many: Fedora, Arch, Debian, Gentoo, PCLinuxOS, OpenBSD... the list goes on and on.

    Every distro lab doesn't have every laptop in the world, but one of them may have yours. Therefore one of the other versions of UNIX may work, but you won't know till you try it...

    Re: Upgraded from Ubuntu 19.04 to Ubuntu 19.10 - now laptop freezes after couple minu

    Hi,

    The problem with this suggestion is that another distribution may or may not work at all. I narrowed down the issue to the Wifi adapter, but another distrib might have issues with something else (e.g. the GPU being a recent GTX1650). Due to time constraints, and due to me being used to high-level Ubuntu (instead of low-level Arch for example), I really do not want to spend weeks trying each distrib one by one until one works (if there is one!). I also see people having issues with this Adapter on the Redhat bugzilla, on CentOS systems and on Juno among others, so this is widespread.

    I ran a fresh 19.10 from an USB drive and the same issue happened. I also managed to find the exact model of my Wifi adapter: Intel Wi-Fi 6 AX200 160MHz
    There are Linux drivers over there: https://www.intel.com/content/www/us...etworking.html

    I downloaded the .tar file, extracted it and moved the file iwlwifi-cc-a0-46.ucode to /lib/firmware. However I'm not exactly sure how to tell my system to use this new driver. This is the view of the "Additional drivers" from the software manager:

    https://i.imgur.com/aK4DoDV.png

    The iwlwifi option is grey and I cannot pick it. Choosing the only available option "Continue using a manually installed driver" doesn't seem to do anything, because as soon as I close and relaunch the software manager it comes back to the same view.

    This is the output of modinfo iwlwifi : https://paste.ubuntu.com/p/gYNDyPtfPJ/

    I don't see my custom driver. I also check dmsg :

    Code:
    david@David-Thinkpad:~/Desktop/iwlwifi-cc-46.3cfab8da.0$ dmesg | grep iwlwifi

    [    6.139175] iwlwifi 0000:52:00.0: BIOS contains WGDS but no WRDS
    It looks like the card is detected but the firmware loaded is version 48, whereas from the name of the file I downloaded I'm expecting version 46.

    How can I tell my computer to use the correct firmware ?

    If there is no way, can I black list my Wifi adapter? Tell my computer to forget about it, not use it at all, and instead I use some USB wifi adapter that I have lying around (and which worked on Ubuntu 19.04).

    So I downgraded to Ubuntu 18.04 LTS. I will use an USB Wifi adapter instead of battling the built-in Wifi and drivers.

    It seems that on 19.10, the card is detected but something goes wrong and it leads to constant freezes. On 18.04, the card isn't even detected which also means the system is stable.

    Probably the driver is loaded as a module.
    Those are located in /usr/lib/modules folder and renaming the bad one as *.bad could be a (dirty but useful) solution

    What about the backport driver in 18.04 which is LTS?
