OpenRGB fails to read i2c devices for MSI motherboard

English Applications
1

When running OpenRGB I get “[i2c_smbus_linux] Failed to read i2c device PCI device ID” for the 2 rgb controlers used on my motherboard.

I tried setting acpi_enforce_resources=lax, enabling i2c_dev and i2c_piix4, reinstalling the udev rules, but to no avail.

2

Did you install the openRGB package from openSUSE Tumbleweed repo.
If yes, try to install libi2c0 also.
Then reboot.

3

I checked and both are already installed and the source listed for them is openSUSE.
Weird.

4

I didn’t tried to do some settings like your first post. Try taking that out.
The first time I run openRGB I got an error also regarding the i2c-dev but after installing
libi2c0 because it wasn’t installed when I install the openRGB and then did the modeprobe -i2c-dev the error was gone and it started working.

My mobo is ASUS AMD

It didn’t work before either. If that can help the exact model of my MoBo is the MSI Gaming Plus WIFI X670E. Also my pc originally had Fedora for a day or two and OpenRGB did work on there (however fedora had a bunch more issues on it).

Hi @HattedRobot . Do you have the sensors installed? If you install it might help pulling some missing dependencies required by openRGB.

7

According the website, this board or Mystic Light is not listed as supported.

8

Please elaborate. Do you mean the board sensors ?

9

Yes, but again on Fedora it did work so this is probably a problem with openSUSE configuration or dependencies.

@HattedRobot That you would need to investigate as to what was actually installed on Fedora (incl. any patches) for the likes of the OpenRGB version which by the looks is a git pull (250311).

Look at installing the version (OpenRGB-1.0~rc2+git32.gda9a96e3) from https://build.opensuse.org/package/show/hardware/OpenRGB

11

Sorry to sound dumb/blind, but where is the button to download ?

12

@HattedRobot there isn’t unless you login and select the distribution. Or browse to the repository, or;
zypper in https://download.opensuse.org/repositories/hardware/openSUSE_Tumbleweed/x86_64/OpenRGB-1.0~rc2+git32.gda9a96e3-25.3.x86_64.rpm

You can add the repo and accept the signing key as well if wish to go that route?

With this version when I try to run OpenRGB it justs freezes my pc. However now it also seems to detect my MoBo in the terminal and my GPU in the ui before completely freezing. However I did not see a message for RAM detected.

14

I have to add that It doesn’t actually completely freeze and I get a frame every one or two minutes. Also it does that after the command “openrgb -l” completes.

15

I did not manage to fix this, but I did find a workaround. Install fedora on a usb stick and use openrgb here to change the colors for the mobo. It also seems to remember after a reboot for the gpu too so that’s a win. I then loaded the version that doesn’t crash my pc to setup the ram sticks. I will not mark this as solved as this is not a fix.

16

I just want to conclude by saying that I switched to CachyOS and the issue was still not fixed but upon looking at their forums I saw that this may be an issue with the AMDGPU driver with the 9070XT graphics card and not with the distro or OpenRGB. Fedora probably happened to patch a certain bug in the driver or other pieces of software interfacing with it.

I disabled OpenRGB device search for the 9070 XT and it seems to work.
