2852 |Dialog:
Some internal devices may not be detected:
One or more I2C or SMBus interfaces failed to initialize.
RGB DRAM modules, some motherboards' onboard RGB lighting, and RGB Graphics Cards, will not be available in OpenRGB without I2C or SMBus.
How to fix this:
On Linux, this is usually because the i2c-dev module is not loaded.
You must load the i2c-dev module along with the correct i2c driver for your motherboard. This is usually i2c-piix4 for AMD systems and i2c-i801 for Intel systems.
See help.openrgb.org for additional troubleshooting steps if you keep seeing this message.
If you are not using internal RGB on a desktop this message is not important to you.
