MSI B650 Motherboard RGB / Razer Barracuda X Chroma Not Detected; Latest AppImage Crashes (SIGSEGV) but Detects RAM; Older AppImage Lacks RAM Detection & Crashes on Rescan; Pacman GUI Fails (Garuda Linux KDE Wayland)


I am experiencing multiple issues with OpenRGB on my system. I have performed extensive troubleshooting and can provide detailed observations and logs.

1. System Environment:

  • Operating System: Garuda Linux (Arch-based)
  • Desktop Environment: KDE Plasma
  • Display Server: Wayland
  • Kernel Command Line: 
    BOOT_IMAGE=/@/boot/vmlinuz-linux-zen root=UUID=84981530-76a4-467a-b066-a6c9d4a2d73a rw rootflags=subvol=@ quiet loglevel=3 acpi_enforce_resources=lax ibt=off

2. Working Configuration (Current Solution):

Currently, the most stable version for basic GUI functionality and profile management is OpenRGB 0.9 (AppImage: OpenRGB_0.9_x86_64_b5f46e3.appimage).

  • GUI: Launches successfully upon initial execution.
  • Profile Saving: Works correctly.
  • Controllable Devices (with 0.9 AppImage):
    • Razer Goliathus Extended Chroma mouse mat
    • ASUS mouse
    • Mountain Everest Max keyboard
    • HyperX Quadcast S microphone
  • System Setup Confirmed:
    • udev rules are correctly installed and reloaded.
    • Kernel parameter acpi_enforce_resources=lax is correctly applied.
    • No conflicting OpenRGB background processes are running when tested.

3. Specific Problems Encountered:

3.1. Hardware Not Detected / Controllable (Consistent Across All Versions):

  • MSI B650 Tomahawk WiFi Motherboard (Integrated RGB / Mystic Light):
    • The motherboard's integrated RGB lighting (likely controlled by Mystic Light) is not detected or controllable by any OpenRGB version tested.
    • BIOS setting to turn off RGB lights works, but does not enable OpenRGB control.
    • Relevant Log: i2cdetect -y 0 output (pasted below) shows activity on the bus, but no new devices are detected after applying acpi_enforce_resources=lax.
  • Razer Barracuda X Chroma Headset:
    • This USB headset is not detected or controllable by any OpenRGB version tested.

3.2. GUI Launch Failure (pacman-installed version):

  • OpenRGB Version: 0.9-4 (installed via sudo pacman -S openrgb from Arch repos)
  • Problem: When launching openrgb or openrgb --gui, the full GUI window does not appear. Only a small icon appears in the system tray. The application does not crash.
  • Observations: The terminal output shows qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in "" and QFont::fromString: Invalid description warnings.
  • Steps to Reproduce:
    1. Install OpenRGB via pacman.
    2. Run openrgb --gui in the terminal.

3.3. Latest AppImage Crashes (SIGSEGV) BUT Detects RAM:

  • OpenRGB Versions: Latest AppImages downloaded from openrgb.org (e.g., 1.0rc1, 1.0rc2 if available, or similar current versions).
  • Problem: These versions crash immediately upon launch with a SIGSEGV (Segmentation Fault - Address boundary error).
  • Crucially: When these versions were briefly able to launch before crashing, they DID detect and could control the Kingston DDR5 RAM.
  • Steps to Reproduce:
    1. Download latest AppImage from openrgb.org.
    2. chmod +x YourLatestAppImage.AppImage
    3. ./YourLatestAppImage.AppImage --gui
  • Observations: (See full terminal output below for SIGSEGV details).

3.4. Older AppImage Instability & Limited Detection (0.9 AppImage):

  • OpenRGB Version: 0.9 (AppImage: OpenRGB_0.9_x86_64_b5f46e3.appimage)
  • Problem 1 (RAM): The Kingston DDR5 RAM is NOT detected or controllable by this version, despite being detected by the newer crashing AppImages.
  • Problem 2 (Rescan Crash): The application crashes with a SIGSEGV (Segmentation Fault) when attempting to "Rescan devices" from within the GUI.
  • Steps to Reproduce (Rescan Crash):
    1. Launch ./OpenRGB_0.9_x86_64_b5f46e3.appimage --gui.
    2. In the GUI, go to Settings -> Rescan Devices.
  • Observations: fish: Job 1, './OpenRGB_0.9_x86_64_b5f46e3.ap…' terminated by signal SIGSEGV (Address boundary error)
