Intel NUC, kodi on 4K is limited to 30FPS

  • Looks like the firmware file is missing for your GPU:

    Code
    1. [ 1.118734] i915 0000:00:02.0: Direct firmware load for i915/bxt_huc_ver01_07_1398.bin failed with error -2
    2. [ 1.118739] [drm] Failed to fetch valid uC firmware from i915/bxt_huc_ver01_07_1398.bin (error -2)
    3. [ 1.120085] [drm] GuC firmware load skipped

  • How do you get the firmware for the gpu? This was a fresh install of @escalades newest version of his community build.

  • I was able to get the new version installed but still no 3840x2160 @60 I do not see the same firmware error in the log though. Thank you very much for all the help.

  • Firmware loads now at least, but I guess that wasn't the issue:

    Code
    1. [ 1.098012] [drm] Finished loading DMC firmware i915/bxt_dmc_ver1_07.bin (v1.7)
    2. [ 1.120486] [drm] GuC firmware load skipped
    3. [ 1.121059] [drm] Initialized i915 1.6.0 20170123 for 0000:00:02.0 on minor 0

    Here's a build of mine with Linux 4.12 you could try that: LibreELEC-Generic.Haswell.x86_64-8.0-devel-20170710.tar - Google Drive


    It's also worth a shot trying the modesetting driver instead of Intel's DDX driver:


    Code
    1. # cp /etc/X11/xorg-modesetting.conf /storage/config/xorg.conf && systemctl restart xorg
  • hm Its probably just me, I tried to flash the image using the USB tool it did not work, I ended up with a badly formated usb. I tried to flash a normal image to get the boot manager on the USB. Then overwrite the files on the usb with the files from your tar archive but it still wont boot. am I missing something ? maybe gwilly7 will have more luck

  • Maybe there is additional information in the xorg log:


    Code
    1. cat /var/log/Xorg.0.log|pastebinit


    Finally you can try to add the mode manually:

    Code
    1. xrandr --newmode "3840x2160p60" 593.41 3840 4016 4104 4400 2160 2168 2178 2250 +hsync +vsync
    2. xrandr --addmode DP1 3840x2160p60
    3. xrandr --output DP1 --mode 3840x2160p60

    This worked perfect, gave me 59.94 for refresh rate. I can not thank everyone enough for your help. I am so happy to finally have this working.


    After further testing this only works until reboot. I will have to find a way to run these commands on startup. Below is my new xrandr info

  • For a recent NUC I would recommend a community build with the latest and greatest kernel / display driver stack. Try mine or Milhouse's.


    Does your build support Hardware 10bit HEVC decoding

  • I cant get your build LibreELEC-Generic.Haswell.x86 to work. I tried updating, I tried installing from a USB, I tried manually replacing files. What am I missing? The screen always gets stuck on SYSLINUX 6.03 (bootloader prob)

  • Without sifting through all the replies you have here, I can guarantee you the NUC can display 60 fps, at least on 1080p. I have 4 here, 1 of which is the cheapest model NUC (Celeron) and they all can handle 60 fps from SmoothStreams

    Fine.


    To make it persistent an approach can be:

    Code
    1. mkdir -p /storage/.config/system.d/xorg.service.d
    2. cat >/storage/.config/system.d/xorg.service.d/randr.conf <<EOF
    3. [Service]
    4. ExecStartPost=-/bin/sh -c ". /etc/profile; exec /bin/sh /storage/.config/xorg.xrandr.sh"
    5. EOF

    And put the first two xrandr lines into /storage/.config/xorg.xrandr.sh


    Is completely untested.


    If someone with working 4k environment posts the output of xrandr --listmonitors --verbose|pastebinit possibly missing modes can be added too.

  • I have not been able to get this to work. Is there a log that might show where I am going wrong.


    here is the contents of the two files created.


    LibreELECNuc:~ # cat /storage/.config/system.d/xorg.service.d/randr.conf

    [Service]

    ExecStartPost=-/bin/sh -c ". /etc/profile; exec /bin/sh /storage/.config/xorg.xr andr.sh"

    LibreELECNuc:~ # cat /storage/.config/xorg.xrandr.sh

    xrandr --newmode "3840x2160p60" 593.41 3840 4016 4104 4400 2160 2168 2178 2250 +hsync +vsync

    xrandr --addmode DP1 3840x2610p60

    Thank you very much for your help once again.
