Sorry for the delay I've been pretty busy. It's a Samsung 870qvo 8tb connected with a sata enclosure (https://a.co/d/eGDQTO5).

Htpc is a Nucbox g5.

I'll get the journal logs later and put them here

Hi guys! So I've been having a super frustrating time trying to get my EXT4 drive to even mount. I can plug it into my arch laptop and it is immediately recognized and mountable. I try on libreelec and it takes many restarts and shutdowns and plugs/unplugs of the drive to get it to mount, making for a really annoying experience. I've checked log files and dmesg and every time I plug in nothing shows up in either, until it randomly works in which dmesg will show the mount. I was thinking it was my USB to sata adapter, but I question that given that out of my main arch distribution and an Ubuntu, kubuntu, and another arch, it is instantly recognised in blkid/lsblk/fdisk there

Great, that worked! And now it does display which is perfect. However a few questions. I can't seem to tell from the docs, but all my media is native 4k. Is this downscaling to 1080p then having tv upscale? Or will this auto output it at 4k when it should and then just have the GUI ONLY at 1080p? Thanks!

Ah so I forgot to turn on the change refresh rate thing in player settings, so that auto selected. But then black screen again.

HOWEVER, a bunch of googling yielded results. The HDMI Ultra HD Deep Color setting was my issue. With that turned on no 4k would display. With it off, it works. Any idea what the setting is and why it killed the video out? And is there a solution to make it work with it on (since the setting seems cool)

video=HDMI-A-1:1920x1080M@60

If the box is connected to the HDMI-A-1 connector append this ^ to boot params in syslinux.cfg and see if forcing the initial DRM output to 1080@60 helps. Adjust as needed for whichever connector is connected. You want to run the GUI at 1080p anyway (see: https://wiki.libreelec.tv/configuration/4k-hdr).

Hi, so I tried to do that in /flash/syslinux.cfg but I don't have permission to write even as root. Just says read-only file system, so I cannot modify the files!

here is log

So when I boot up my mini PC when connected to LG smart tv, I get video signal, and it shows the initial bios screen. Then when you would normally get the libreelec boot screen and Kodi boot screen, then Kodi menu, all of that part it's black screen.

Via

tail /sys/class/drm/*/status

I am able to see both the HDMI port on my box, and it shows connected for the port the TV is plugged in to. So the connection is good. No idea why this is happening. Maybe a libreelec/Kodi setting?

Any help figuring out what's up would be appreciated! Thank you

I know I'm late to the party, did you get it figured out? I am not sure which libraries you had unsatisfied via ldd but when I did it I was missing the basic x11 stuff and jansson. I was able to statically embed jansson into my build of ddcutil and then build it without libusb, drm, and x11, and that got it up and running for me. Still need to mess around with keybinding it now. But I am not on the pi platform so it could be different, if you want the steps I took to do it:

I did my building on ubuntu,
1) Get the build tools + dependencies
2) statically build jansson (./configure --enable-static --disable-shared CFLAGS="-fPIC")
3) clone, etc.. for ddcutil, setup, then config (./configure --disable-usb --disable-drm --disable-x11 LDFLAGS="-Wl,-Bstatic -ljansson -Wl,-Bdynamic")
4) build

hope that helps!
