Hello! Fedora 39, I've been stumped by this issue for a long time.
I have 4 DDR4 sets of 8 GB G.SKILL Trident Z RGB.
I tried the latest Flatpak, RPM as well as building the master
branch for source, but every version can't find Trident Z in the "Supported Devices" section, and it doesn't show up under Devices.
I validated that the i2c modules were loaded, and the udev rules were put in place, both using the RPM and by running the script provided over at https://openrgb.org/udev.html
When running OpenRGB, in the terminal, I get:
[i2c_smbus_linux] Failed to read i2c device PCI device ID
even when running as sudo
.
My motherboard is an AORUS X470 ULTRA GAMING (cringe name, I know), if it makes any difference for i2c support. As a side note, this motherboard has RGB, but it's not detected in OpenRGB. I think it should be supported, and I see it when running openrgb --list-devices -vv
, but maybe the revision is wrong.
[Gigabyte RGB Fusion 2 SMBus] Success - Found 'X470 AORUS ULTRA GAMING-CF' in the JSON list
[Gigabyte RGB Fusion 2 SMBus] Bus 02 is not a motherboard or the subvendor does not match the one for Gigabyte Technology Co., Ltd., skipping detection
[Gigabyte RGB Fusion 2 SMBus] Bus 06 is not a motherboard or the subvendor does not match the one for Gigabyte Technology Co., Ltd., skipping detection
[Gigabyte RGB Fusion 2 SMBus] no devices found
[Gigabyte RGB Fusion 2 SMBus] detection end
Please let me know if further details are required.
TIA!
Trident Z RGB falls under ENE DRAM and should work fine as long as you have the appropriate i2c driver loaded for your motherboard.
Can you post the output of lsmod | grep i2c?
Hello! I just want to poke you on this :)
Oh, you have a Gigabyte motherboard. These have a quirk with i2c where you have to add a kernel command line parameter. I forget exactly what it is, maybe "acpi_enforce_resources=lax"? I think this is mentioned in the Readme on Gitlab.
Ah thank you, I didn't spot it in the README, I'll give it a try :)
I had the opportunity to test this today, thank you, it's what I was missing! I should have RTFM'd :)
