One of the biggest complaints about RGB is the software ecosystem surrounding it.  Every manufacturer has their own app, their own brand, their own style.  If you want to mix and match devices, you end up with a ton of conflicting, functionally identical apps competing for your background resources.  On top of that, these apps are proprietary and Windows-only.  Some even require online accounts.  What if there was a way to control all of your RGB devices from a single app, on both Windows and Linux, without any nonsense?  That is what OpenRGB sets out to achieve.  One app to rule them all.

## WARNING!

This project interacts directly with hardware using reverse engineered protocols.  While we do our best to make sure we're sending the right data, there is always some risk in sending data to hardware when we don't understand exactly how that hardware works.

There have been two instances of hardware damage in OpenRGB's development and we've taken precautions to prevent it from happening again.

  * The Mystic Light motherboard code bricked the RGB controller of some MSI motherboards.  The code was disabled and reworked.  We have been re-adding these motherboards to the support list as we verify that the new code works with them.  Affected boards can be unbricked with a Nuvoton Nu-Link adapter.
  * There were reports of bricked Gigabyte Aorus Z390 motherboards caused by dumping SMBus address 0x68 in an attempt to reverse engineer the RGB.  Due to this, the SMBus Tools page on OpenRGB is hidden by default now as it has no real use to non-developers.

### SMBus Access
  *  **You must run the application as Administrator the first time to allow WinRing0 to set up.  It can be run as a normal user afterwards**
  * Early versions of OpenRGB used InpOut32. This is no longer needed and should be removed to avoid warnings by some anti-cheat software. You can uninstall Inpout32 by following the instructions [here](https://gitlab.com/CalcProgrammer1/OpenRGB/-/issues/669#note_461054255).

### USB Access

  *  Early versions of OpenRGB used the WinUSB driver, installed using Zadig.  This is no longer required, and you need to uninstall the WinUSB driver if you previously installed it.  You can uninstall the WinUSB driver by following [this guide](https://gitlab.com/CalcProgrammer1/OpenRGB/-/wikis/Frequently-Asked-Questions#i-installed-the-winusb-driver-for-a-device-and-i-wish-to-uninstall-it).

### SMBus Access

  * SMBus access is necessary for controlling RGB RAM and certain motherboard on-board LEDs.
  * If you are not trying to use OpenRGB to control RGB RAM or motherboard LEDs, you may skip this section.
  * ASUS and ASRock motherboards have their RGB controller on a secondary SMBus interface and requires a Linux kernel > 5.7 <sup>[commit](https://github.com/torvalds/linux/commit/f27237c174fd9653033330e4e532cd9d153ce824)</sup>
  * Allowing access to SMBus:
    1. Install the `i2c-tools` package.
    2. Load the i2c-dev module: `sudo modprobe i2c-dev`
    3. Create the i2c group if it does not already exist: `sudo groupadd --system i2c`
    4. Add yourself to the i2c group: `sudo usermod $USER -aG i2c`
    5. If you want you can load the i2c-dev module at boot: `sudo touch /etc/modules-load.d/i2c.conf && sudo sh -c 'echo "i2c-dev" >> /etc/modules-load.d/i2c.conf'`
    6. Load the i2c driver for your chipset:
    <details>
    <summary><h6>Intel</h6></summary>

     * `sudo modprobe i2c-i801`
     * `sudo modprobe i2c-nct6775` - Secondary controller for motherboard LEDs (requires [kernel patch](https://gitlab.com/OpenRGBDevelopers/OpenRGB-Wiki/-/blob/stable/OpenRGB-Kernel-Patch.md))

    </details>
    <details>
    <summary><h6>AMD</h6></summary>

     * `sudo modprobe i2c-piix4`
     * Unmodified kernel will have one interface, patched kernel will have two.  The first at 0x0B00 and the second at 0x0B20.  The 0x0B20 interface is for motherboard LEDs.

    </details>

    * If RGB RAM or certain motherboard on-board LEDs are not loading the profile on startup, you need to add the loading entries to: `/etc/modules-load.d/`
      - i2c-dev
      - i2c-i801 or i2c-piix4 (according to your chipset)

     ----

  *  You'll have to enable user access to your SMBus if you don't run as root.
      - List all SMBus controllers: `sudo i2cdetect -l`
      - Note the number for PIIX4, I801, and NCT6775 controllers.
      - Give user access to those controllers. If you have not installed OpenRGB from a package (e.g. deb, RPM or from the AUR) then most likely you need to [install the UDEV rules](#installing-udev-rules-manually).
  *  The i2c-nct6775 kernel module requires patching, please refer to [instructions here](https://gitlab.com/OpenRGBDevelopers/OpenRGB-Wiki/-/blob/stable/OpenRGB-Kernel-Patch.md)
  *  Some Gigabyte/Aorus motherboards have an ACPI conflict with the SMBus controller. Please [add a kernel parameter](#kernel-parameters) to resolve this conflict.

### USB Access

  *  USB devices require [udev rules](#installing-udev-rules-manually) to access as a normal user.
  *  Alternatively you can run OpenRGB as root to detect all USB devices. (Not recommended)
  *  USB based Gigabyte AORUS motherboards may also have an ACPI conflict. Please [add a kernel parameter](#kernel-parameters) to resolve this conflict.

### Installing UDEV rules manually

  *  If you have installed OpenRGB from a package then latest UDEV rules are installed locally at `/usr/lib/udev/rules.d/60-openrgb.rules`
  *  Flatpak and Appimage "packages" will need to install this file manually.
  *  Udev rules are built from the source at compile time. When building locally they are installed with the `make install` step to `/usr/lib/udev/rules.d/60-openrgb.rules`
  *  If you need to install the UDEV rules file manually you can also download the [latest compiled udev rules](https://gitlab.com/CalcProgrammer1/OpenRGB/-/jobs/artifacts/master/raw/60-openrgb.rules?job=Linux+64+AppImage&inline=false) from Gitlab.
      - Copy this 60-openrgb.rules file to `/usr/lib/udev/rules.d/`
      - Then reload rules with `sudo udevadm control --reload-rules && sudo udevadm trigger`

### Kernel Parameters

  *  To resolve an ACPI conflict add the `acpi_enforce_resources=lax` kernel parameter.
  *  If you want to check if the kernel was loaded with this option you can execute this command from the terminal once you've rebooted.
     * `cat /proc/cmdline`

     <details>
     <summary><h5>Arch</h5></summary>
