    Hi there,

    I'm trying to get my razer blade working with a second external monitor over HDMI and am having some trouble.

    I'm using Antergos on my new Razer Blade (14", full-HD). I'm currently dual booting Win 10 (default install) alongside Antergos using Grub.

    I've installed the Nvidia drivers using pacman as well as the ACPI tables fix for Optimus cards here: https://github.com/m4ng0squ4sh/razer_blade_14_2016_acpi_fix

    ➜ ~ pacman -Q | grep nvidia
    nvidia 378.13-3
    nvidia-settings 378.13-1
    nvidia-utils 378.13-5

    I can get bumblebee running, and it appears my card is working. Here's the (relevant portions) of ouput of lspci -v

    00:02.0 VGA compatible controller: Intel Corporation Device 591b (rev 04) (prog-if 00 [VGA controller])
    Subsystem: Razer USA Ltd. Device 6755

    Kernel modules: nouveau, nvidia_drm, nvidia

    I've tried removing nouveau (removed the xf86-video-nouveau package and ran modprobe -r nouveau), but I'm still puzzled why the kernel module nouveau is still in use.

    Anyways, I can get into nvidia-settings using the following command:
    sudo optirun -b none nvidia-settings -c :8

    I cannot for the life of me get the system to detect the external display, though.

    Here is the output of xrandr.

    ➜ ~ xrandr

    Help would be greatly appreciated!

    Hello there!

    Do you know if you're getting the connection event trigger when plugging the monitor in?

    Try running
    cat /sys/class/drm/card0-HDMI-A-1/status
    both with and without the monitor attached, and see if you get anything different (I'm guessing no, but worth covering all bases first)?

    May also seem like a derpy question, but assuming the monitor is working fine with the windows partition?

    And finally, have you tried disabling the main laptop display and forcing the display through to the secondary monitor, both in desktop mode and just as a shell? (multiple ways to do this, starting with easy, such ans hitting fn + F4 getting progressively more complex/dangerous :stuck_out_tongue_winking_eye: )

    I have been battling the same issue since I got mine last week. No idea how to solve it. I get the same xrandr output as you do. If I switch to the NVIDIA card in the nvidia-settings, the external monitor is detected (but sadly there's a bug in Unity 7 that makes it hard to use both internal and external monitor). So I can use just the external monitor on the NVIDIA card fine. But yeah, that means I have to switch back to Intel every time I am on the move. Such a hassle. I am guessing that the HDMI port is connected directly to the GTX, and that the NVIDIA driver for Ubuntu doesn't include the necessary code for forwarding that port to the Intel Graphics. I'm hoping a solution will appear soon though.

    And yes, everything works fine in Windows.

    Thanks for the response Pete.

    So running cat /sys/class/drm/card0-HDMI-A-1/status yielded the same 'disconnected' when plugged in and unplugged.

    The windows partition is working just fine, so it seems purely like a software issue.

    I have not tried anything like you suggested yet. My nvidia-settings window (run using sudo optirun -b none nvidia-settings -c :8) doesn't seem to pick up the external monitor at all. Here's a snapshot of my display config.


    Thanks for all of the help.

    Hey, sorry for the late reply.

    Just a couple of other questions, are you using the default Gnome desktop? Also, may be worth trying another distro and see if it works with one of those, that way you can narrow it down to a kernel/hardware issue or just a flavour issue.

    If you get the chance to try and force the display through just the external monitor, let me know how it goes. I know certain desktops (namely unity) struggle with the whole multi monitor thing on laptops sometimes.

    Hi, I bought mine a few month ago and installed Gentoo. AFAIK there is an issue with the intel skylake chip and does not detect the external output. I'm still searching for a solution.
    If it helps, you can work around this by setting a pure nvidia configuration (disable the intel and nouveau support). Using the nvidia driver works fine with external monitor, but the battery drains in less than 2 hours.
  7. I just got this working on Manjaro after a lot of reading and fiddling with things. Here are the steps I took:

    1. install the bumblebee nvidia drivers (I just used the GUI in manjaro settings -> hardware)
    2. run
      at the terminal. It starts a daemon that looks for an external monitor connecting
    Yeah it was that easy -_-
    This is on manjaro gnome if that matters.
    I also updated the kernel to the latest but I'm not sure if it's needed for this to work.
    It's possible that some other thing I did before was also necessary but I don't think so.
    I plugged in my 1080 tv and it extended the desktop automagically, but the resolution was only 1024x768 and didn't have the option in the GUI to resize. I tried using xrandr to set it to 1920x1080 but it just disconnected. Ill probably have to mess around some more with xrandr but at least the output works.
