There is still is one little bug in my setup. OpenRGB now shows 8 ballistics RGB devices where I only installed 4. Control-wise it however doesn't matter since the last 4 are exactly equal to the first 4. This is cased by a small difference in location between the two menu items that are created for the same ram (i.e. /dev/i2c-1 vs /dev/i2c-2). Probably caused by the ram layout, not the OpenRGB program.

@TheRogueZeta I verified that the problem is solved in the kernel that I build using steps given in #1984 (comment 872699651). As a result, it looks like the patch created by @terry.bowman is working in ubuntu 20.04 under kernel version 5.13. Thanks again for all the effort you put into getting this issue fixed!

For future reference, I was able to apply the patch series on my kernel and install it on Ubuntu 20.04 using the following steps:

  1. Clone the GitHub kernel repository, https://github.com/torvalds/linux.
  2. Check out the version of the kernel you are currently using.
  3. Apply the latest version of the patch that was mentioned by @superm1.
    • This can be done using the b4 python package (i.e. b4 am -o- https://lore.kernel.org/linux-i2c/[email protected]/T/#mde6458f2c96113daccb27ccef0cf8bce2d47fcc7 | git am) or by downloading the mbox.gz file directly and using it in the git am command.
  4. Copy your old kernel config using cp -v /boot/config-$(uname -r) .config.
  5. Run make olddefconfig to keep old config settings while using defaults for the new options.
  6. Add a signing certificate according to https://askubuntu.com/a/1372567/822484.
  7. Build the kernel using make deb-pkg -j $(nproc) command.
  8. Install the kernel using sudo dpkg -i ../linux-headers-*.deb ../linux-image-*.deb.
  9. Update grub using sudo update-grub2.
  10. Reboot into the new kernel through the advanced grub menu.

@TheRogueZeta Thanks a lot for the update. I will check if the new patch fixes the ram detection.

@TheRogueZeta I'm now trying to see if building the kernel from source while applying the patch (i.e. https://launchpad.net/~vicamo/+archive/ubuntu/ppa-1950062)fixes the error.

In the meantime, are you sure I don't also need the patch explained in the README https://gitlab.com/CalcProgrammer1/OpenRGB#smbus-access-1 as I'm on an Asus B550 board? Based on some issues, it already should be merged in the upstream, but the official documentation has not yet been updated.

@TheRogueZeta I tried verifying the fix provided by https://launchpad.net/~vicamo/+archive/ubuntu/ppa-1950062 but I still don't see my RAM sticks in OpenRGB. I installed the fix as follows:

  1. sudo add-apt-repository ppa:vicamo/ppa-1950062.
  2. sudo update.
  3. sudo install linux-oem-5.14-headers-5.14.0-2023 linux-oem-5.14-tools-5.14.0-2023 linux-oem-5.14-tools-host.
  4. sudo apt reboot.
  5. sudo openrgb.

Maybe I need to apply the patch directly on my kernel?

Let's now set the following colours using the old dragon centre app: #2faced - (47, 172, 237), #dedca7 - (222, 220, 167), #b00b1e - (176, 11, 30), #bad801 - (186, 216, 1), #da7a11 - (218, 122, 17), #bec001 - (190, 192, 1), #5ead13 - (94, 173, 19), #7aff1e - (122, 255, 30), #7AFF1F - (122, 255, 31), #7AFF20 - (122, 255, 32), #7AFF21 - (122, 255, 33), #7AFF22 - (122, 255, 34), #7AFF23 - (122, 255, 35), #7AFF27 - (122, 255, 39), #7AFF29 - (122, 255, 41), #7AFF2A - (122, 255, 42), #7aff28 - (122, 255, 40), #7af51e - (122, 245, 30), #70ff1e - (112, 255, 30):

Let's quickly check when the values are changing. Let's start with #7AFF1E again and increase the B value until a change is seen. I will not display the bytes that are not related to the RGB signal:

It looks like this device does not support a continuous RGB spectrum, but simply parts of it. This can also be seen from the fact that some colours don't display correctly on the GPU.

@Dracrius Based on the informatino you gave me I did another capture, but now only from starting up the MSI mystic light program. When doing this it gives the following files:

nvapi_897093.txt

nvapi_907343.txt

These files are created by two processes communicating with the MSI GTX 1070TI on address 0x38:

- **nvapi_897093** is the communication from the `MSI.CentralServer.exe` program. This program is the new https://www.msi.com/Landing/MSI-Center, which contains both the Mystic Light Tool and the System Information tool.
- **nvapi_907343** is the communication from the `LedKeeper2.exe` program. This program is equal to the old [Mystic Light tool](https://www.msi.com/Landing/mystic-light-rgb-gaming-pc/)..

Both processes send the following byte stream when connecting to the GPU. Maybe to establish a connection?:

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x01 Size: 0x01 Data: 0x25

After that, the MSI center doesn't send any bytes anymore while the Mystic Light Tool sends a byte stream to set the colour that it had in memory (RGB: 122, 255, 30 - #7aff1e) to the GPU:

It's again hard to see where the colours go, but the byte sequence is equal except the first part, which is new. Let's change one value in the colouring (i.e. RGB: 122, 255, 31 - #7aff1f).

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x26 Size: 0x01 Data: 0xFA

This gives us the same command, meaning that the colour values are rounded. Lets make a bigger change (i.e. RGB: 122, 255, 40 - #7aff28). This gives us:

==Color command similar to the initial command==
NvAPI_I2CReadEx:  Dev: 0x38 RegSize: 0x01 Reg: 0x31 Size: 0x01 Data: 0x00 << Reading current color?

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x23 Size: 0x01 Data: 0x10 << R (rounded)
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x24 Size: 0x01 Data: 0x20 << G (rounded)
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x25 Size: 0x01 Data: 0x06 << B (rounded)
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x26 Size: 0x01 Data: 0xFA << Close or alpha channel which does not exist?

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x22 Size: 0x01 Data: 0x00
=SET COMMAND=

=RGB command=
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x23 Size: 0x01 Data: 0x10 << R (rounded)
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x24 Size: 0x01 Data: 0x20 << G (rounded)
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x25 Size: 0x01 Data: 0x06 << B (rounded)
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x26 Size: 0x01 Data: 0xFA << Close Or alpha channel which does not exist?
=RGB command=

In this since we now changed the B value, the following lines are changed:

When we change the G value, we get the following change:

When we change the R value, we get the following change:

It looks like the following commands are used for setting the colour:

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x23 Size: 0x01 Data: 0x10 << R (rounded)
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x24 Size: 0x01 Data: 0x20 << G (rounded)
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x25 Size: 0x01 Data: 0x06 << B (rounded)
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x26

From this we can see that the control goes as follows. First a general connection read command and a connection command are send:

NvAPI_I2CReadEx:  Dev: 0x38 RegSize: 0x01 Reg: 0x31 Size: 0x01 Data: 0x00

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x20 Size: 0x01 Data: 0x18
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x21 Size: 0x01 Data: 0x01
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x22 Size: 0x01 Data: 0x00
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x23 Size: 0x01 Data: 0xFA

After that this read command always retrieves some information from the GPU:

NvAPI_I2CReadEx:  Dev: 0x38 RegSize: 0x01 Reg: 0x31 Size: 0x01 Data: 0x00

Then this set command is always used:

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x20 Size: 0x01 Data: 0x15
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x21 Size: 0x01 Data: 0x07
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x22 Size: 0x01 Data: 0x00

Then the rounded RGB data is send by modifying this command:

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x23 Size: 0x01 Data: 0x10 << R
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x24 Size: 0x01 Data: 0x20 << G
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x25 Size: 0x01 Data: 0x06 << B
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x26 Size: 0x01 Data: 0xFA << Alpha

Followed by another set command:

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x20 Size: 0x01 Data: 0x20
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x21 Size: 0x01 Data: 0x07
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x22 Size: 0x01 Data: 0x00

and again the same rounded RGB command:

NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x23 Size: 0x01 Data: 0x10 << R
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x24 Size: 0x01 Data: 0x20 << G
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x25 Size: 0x01 Data: 0x06 << B
NvAPI_I2CWriteEx: Dev: 0x38 RegSize: 0x01 Reg: 0x26 Size: 0x01 Data: 0xFA << Alpha

I was not able to find how the program converts the rgb values, maybe rounding or using another data format but we now have more information about which bytes are used for setting the RGB.

I checked the constants in https://github.com/Vipeax/MSI-LED-Tool/blob/master/MSI%20LED%20Tool/Constants.cs, but they are not contained in the capture. Further, the tools seems to be broken.

@Dracrius Thank you so much for looking into my problem. So the missing part we need to find is how the RGB values show up. I will do some more tests to see if I can find them back in the logs. I also found this GitHub project which might help, https://github.com/Vipeax/MSI-LED-Tool.

@TheRogueZeta Thanks a lot for letting me know I overlooked that bug. I added myself as being affected. Hope a fix is merged into the upstream soon.

Description of Bug

I can't get my 4x8gb Crucial Ballistix RGB C16 3200 MHz (BL2K8G32C16U4BL) to show up in OpenRGB under Ubuntu 20.04. They show up without any problems on Windows 11. I think this is due to a permission issue or that I first need to patch the kernel.

To solve the permission problem. I tried adding the udev rules and rebooting the OS, but this unfortunately does not work.

I tried to patch the kernel according to OpenRGB-Kernel-Patch, but haven't been able to successfully do so for kernel 5.13 on Ubuntu 20.04. Furthermore, I however was under the impression that the patch has already been released into the upstream as of v5.2.11 (see https://bugzilla.kernel.org/show_bug.cgi?id=204807#c127).

Please attach device captures here:

I did a device capture using the https://gitlab.com/OpenRGBDevelopers/NvAPISpy tool. During this capture, I send 4 RGB control commands to the MSI GPU.

Captures before sending the RGB signal

The following captures were received before I send any RGB control commands:

nvapi_20312.txt

nvapi_23109.txt

nvapi_12062.txt

nvapi_26375.txt

These are likely coming from startup actions from several device RGB software utilities (i.e. Asus armoury crate, MSI tools).

Captures received during command send

I used the colours given by @Dr_No in https://discord.com/channels/699861463375937578/702322217622700052/784264315900657664 for my captures (i.e. #2faced, #dedca7, #b00b1e, #bad801, #da7a11, #bec001, #5ead13, #7aff1e - converted using https://www.rapidtables.com/convert/color/hex-to-rgb.html). When executing these control commands in the MSI mystic light utility the following captures were received:

nvapi_20312.txt

nvapi_23109.txt

nvapi_12062.txt

nvapi_26375.txt

From these, only the last file seems to be changed compared to the captures that were taken before I send the control commands.
