In this article, we will discuss how to troubleshoot and resolve the ‘No Bluetooth Found’ error on Ubuntu 22.04 LTS for Asus K55VJ. This issue can occur due to a variety of reasons, including disabled Bluetooth in BIOS/UEFI, missing firmware files, or kernel incompatibility. We will walk you through each step, providing detailed explanations and commands to help you understand the process.
Checking if Bluetooth is Enabled in BIOS/UEFI
The first step in troubleshooting this issue is to check if the Bluetooth option is enabled in your laptop’s BIOS/UEFI settings. These settings control the hardware of your laptop, and if Bluetooth is disabled here, it will not be detected by any operating system you are running.
To access the BIOS/UEFI settings, restart your laptop and press the appropriate key (usually F2, F12, DEL, or ESC) during the initial boot process. Once in the BIOS/UEFI settings, look for an option related to Bluetooth and ensure it is enabled. Save any changes and restart your system.
Verifying Bluetooth Hardware
Next, we will verify if the Bluetooth device is recognized by the system. Open a terminal and run the following command:
lspci -knn | grep Net -A3; lsusb; dmesg | grep -i blueThis command performs three actions:
lspci -knn | grep Net -A3lists the network devices along with their driver information.lsusblists USB devices connected to your system.dmesg | grep -i bluefilters system messages for Bluetooth-related entries.
If your Bluetooth device is listed in the output, it means that your system recognizes it. If not, it could indicate a hardware issue.
Checking for Bluetooth Firmware
In some cases, the ‘No Bluetooth Found’ error can occur due to missing firmware files. To resolve this, you can download the linux-firmware package and extract the necessary firmware files. Follow these steps:
- Download
linux-firmware_1.201.tar.xzfrom here. - Extract the downloaded file and locate the
ar3kfolder. - Copy the
ar3kfolder to the/lib/firmwaredirectory. You may need root privileges to perform this action. Use thesudocommand to gain these privileges:
sudo cp -r ar3k /lib/firmware- Restart your computer and check if Bluetooth is now detected.
Updating the Kernel
Sometimes, updating the kernel can resolve compatibility issues and improve hardware detection. To update your kernel to the latest version available for Ubuntu 22.04 LTS, follow these steps:
- Open a terminal and run the following command to update the package list:
sudo apt update- Next, upgrade the existing packages:
sudo apt upgrade- Now, install the latest kernel:
sudo apt install linux-generic-hwe-22.04- Finally, reboot your system to apply the changes:
sudo rebootPlease note that updating the kernel requires some technical knowledge and may not be suitable for beginners. Always backup your important data before making any changes to your system.
Conclusion
If none of the above solutions work, it is possible that your laptop’s Bluetooth hardware is not compatible with Ubuntu 22.04 LTS. In such cases, you may need to consider using an external Bluetooth dongle to enable Bluetooth functionality on your system.
