    what wifi adaptor? If it's an Intel ac7260 then they're notorious for having problems.

    I ripped the 7260 card out of mine which dropped out all the time, and replaced it with an older 6235 card, lost the 11ac function but kept a/b/g/n and bluetooth, and it's totally stable.

    Being a Lenovo you'll have to check if WiFi cards are whitelisted in the BIOS otherwise the machine won't pass POST or won't turn the card on, and if so only buy a branded Lenovo card.

    Great article.

    Have you had spotty wifi with the intel board? Mine drops connections all the time. I have the same X1C3 (i7, etc.) and I'm having that problem in fedora 21. I'm going to try disabling wireless n to see if that helps, but I really don't want to lose the speeds I've been getting when it is connected.

    Also, have you gotten the brightness keys to work?

    This is my first foray into fedora, so I am unsure how backports work, but I'm thinking something like that is the way to accomplish this...but I have a so far limited understanding of fedora, so not sure the way to go. I'm on 3.18 right now, my understanding is it's the latest stable kernel fedora has. Not sure how or even if I want to go newer than that.

    Hi Michael,

    could you please test if one can set charging thresholds with tpacpi-bat (or possibly Tp smapi, although I doubt it) and if they are actually honored?

    Thanks in advance!

    Just that.

    Hmm, I'm confused. Are you saying that the touchpad/clickpad has issues clicking? Or, is there an issue with the physical buttons just above the touchpad (but below the keyboard nipple)?

The only reason I ask is that it seems like the same Broadwell SoC is used for the X1 and the Dell XPS 13 9343. Getting that SoC playing well on the Dell has been an exercise in futility. A BIOS update seems to the the only path out.

    I'd love to know if the X1 suffers from the same touchpad/sound issues. Thanks.

    Get OneLink Pro Dock, a bit more expensive but it works pretty well. Both two external output works with recent kernel (Fedora 21) and matching Intel driver. Main advantage over all that previous USB based docks Lenovo had - it just works as it's just MST hub. It has own USB hub, ethernet and audio but again, it works with recent kernel. Sometimes I have to replug external keyboard, not sure what's wrong. I'll try to do the diff of lspci/lsusb.

    So in the end, I like Carbon. The only issue is that semi-HiDPI display combined with non-HiDPI external displays (and with OneLink Pro dock you can have two Full HD outputs or just one HiDPI). GNOME is almost unusable due to x2 scaling factor. Plasma 5 with some DPI, sizec tweaking works quite well. Hardest issue was to find correct values - it's not too small on HiDPI display and not too big on external LCDs. For Firefox, AutoHDPI extension works (but for some reason it gets confused on Phoronix ).
    So would you recommend the 1080p display over the 2560x1440? If you think the 2560x1440 display is a bad idea, I'm considering getting the T450s with the 1080p, since I connect to VGA projectors every once in a while.

    The ethernet adaptor is a proprietary connector. There is native intel gigabit ethernet on board but the standard rj45 jack is too thick to have directly on the X1 so the adaptor is required. Native On board ethernet is what made me choose the new X1 over the new XPS. I don't want to have to rely on USB adaptors/drivers etc for ethernet.

    I want to install Fedora F21. Any advice on how to proceed?

    1. Did you install via USB stick?

    2. I've never had to deal with UEFI before now. Did you turn it off in the bios?

    3. Did you set it up multi-boot with windows (which it comes with)? I'm thinking to leave windows on a minimal partition (40G/256?).
    I believe F21 install should included the tool to resize the ntfs partition.

    Any other installation hints?
    I am a recent returnee to Linux and more specifically Fedora..Mostly due to the articles here. I have the i5 with 8GB, 256GB SSD and the HiDPI IPS non touch screen. The only distro I had success with UEFI dual booting was F21. My steps below based on many articles out there.
    1. resize the main Windows partition leaving free space( I left ~75GB free). I used windows disk management
    2. I disabled secure boot in the BIOS.
    3. The only way i could get F21 to UEFI boot properly was by using the Fedora Live USB creator windows application to create a USB image to boot and install from.
    4. I let F21 auto partition as it had properly detected the free space on the drive.

    After that all good. Scaling on the hidpi screen seems to work well. Manually adjusting Firefox scaling works...no real solution for chrome yet. Onelink-pro dock seems to work very well although I have yet to connect any external monitors.
