    I'm starting this thread to document the experiences of installing and using Linux on the Lenovo Y50.

    I'm receiving my 4K model Y50 from Klick tomorrow evening. My plan is to wipe the drive, clean install Windows 8.1 for the games that aren't on Linux yet, and dual boot Kubuntu 14.04. I'll post an update then.

    Feel free to discuss any problems you have installing and using Linux on yourY50.

    I'm planning to do the same, Windows 8.1 for games, Ubuntu 14.04 for Android system development. I'm also curiuos about how well the optimus performs with Linux. Unfortunately the Y50 is not yet available in Hungary.

    I did a fresh install of Windows 8.1 and Kubuntu 14.04.

    Optimus:
    Working better in Linux than it does in Windows...
    In Linux I just run a game using: "optirun <game>" and it uses the nvidia graphics like magic.
    In Windows on the other hand I can't get the nvidia control panel settings to stick. They change back every time I close it...

    High DPI:
    It works really well in WIndows 8.1
    Though I have managed to tweak KDE to a very usable state. There are only a few non-critical elements that I can't figure out how to rescale. I'll play with it more later.

    Touchpad driver:
    I can't get the Elantech touchpad driver to work in Linux.
    I get a system message: [ 4.917272] psmouse serio1: elantech: unknown hardware version, aborting...
    The driver must not support this model yet.
    The touchpad works, just no multitouch gestures (scrolling :/ )

    Refresh rate:
    xrandr outputs the allowed modes:
    Code:
    Screen 0: minimum 320 x 200, current 3840 x 2160, maximum 32767 x 32767

    VGA1 disconnected (normal left inverted right x axis y axis)
    HDMI1 disconnected (normal left inverted right x axis y axis)
    VIRTUAL1 disconnected (normal left inverted right x axis y axis)
    If I switch to 1920x1080 @ 59.9 Hz, and I run glxgears, the framerate is still locked to 48 Hz.

    I don't really notice the 48 Hz lock. People really underestimate the value of a consistent framerate, and this machine delivers.

    Let me know if anyone else has any other questions.

    Consistent frame rate is good, but for some games like cs:go I'm pretty sure you can get a consistent 60 on high graphics. 48 is a noticeable downgrade

    I got the touchpad drivers working by installing a backported 3.16 kernel from the deb files here: Index of /~kernel-ppa/mainline/v3.16-rc3-utopic
    I'm using touchégg to configure all the touchpad gestures. Coming from a trackpoint on my old x220, I'm actually starting to like trackpads a little!

    Hi :)
    I'm considering this notebook but I want to use Linux(Ubuntu, Linux Mint, etc) as main the OS.
    How well does linux manage the gpu? Is it possible to install drivers with no problems (overheating and fan noise)? The BIOS allow us to disable the dedicated graphics if needed?

    What do you think? Does it work properly with Linux?

    Thank you

    I'm running Kubuntu and you can install the binary nvidia drivers just by installing the nvidia-331 package. There is no need to disable the dedicated graphics because optimus runs perfectly using the bumblebee and bumblebee-nvidia packages. You can run two seperate applications at the same time, one using intel graphics, and one using the nvidia graphics no problem. In fact I find that optimus is easier to use in linux than it is in Windows.
