Intel Core Ultra 5 225H with Ubuntu 22.04 - Wi-Fi, Display Brightness, and Refresh Rate Not Working

[Samtel9]

Hello,

I am experiencing multiple driver-related issues (or I think they are driver related) with my new laptop running on an Intel Core Ultra 5 225H processor with Ubuntu 22.04 LTS. I have already performed extensive troubleshooting, and it appears to be a lack of driver and/or firmware support for this new hardware platform.

System Information:

• Processor: Intel Core Ultra 5 225H

• Operating System: Ubuntu 22.04 LTS (Jammy Jellyfish)

• Laptop Model: "Lenovo IdeaPad Pro 5 Intel

• Kernel Version: 6.8.0-72-generic

The Issues:

1. Wi-Fi Card Not Working: The wifi isn't even showing up.

2. Display Brightness Control Not Working:

   • The brightness slider appears in the system UI, but adjusting it has no effect on the screen brightness.

   • The backlight control device is named "ideapad," not "intel_backlight".

   • My Troubleshooting: I have added the "acpi_backlight=vendor" kernel parameter to the GRUB configuration. While this enabled the slider, the functionality is absent. Manually writing a value to "/sys/class/backlight/ideapad/brightness" also has no effect. This suggests the kernel driver is not correctly communicating with the display's hardware (or so do I think).

3. Display Refresh Rate Control Not Working:

   • The display is stuck at a single refresh rate (likely 60Hz or a similar default).

   • I am unable to change the refresh rate in the display settings. The option is either missing or locked.

   • This is a common symptom of the integrated GPU driver (i915) not being fully functional.
     
     

I am not very techy not much familiar with linux. I have just started using it as I am working on a live project to learn about their stack. They use Ubuntu 22.04 LTS and ROS2 Humble. I would want to stick with this ecosystem to not face any compatibility issues in the future.

Hello Samtel9,

Thank you for posting in Intel community Forum.

For me to better understand and diagnose the issue further, let me ask you to provide detailed responses to the following questions. This information will help me isolate the problem and determine the most appropriate course of action moving forward.

1. What is the model of the wireless controller?
2. What is the original OS of the laptop?
3. Let me also check, the Wi-Fi and display is working properly before?
4. Did you get this issue just after installing Ubuntu?
5. Please help generate the SSU logs of your system for me to review the drivers. Please refer to the link below for the download link of the application:

Intel® System Support Utility for the Linux* Operating System

If you have questions, please let us know. Thank you.

Hello Micheal,

1. The Wireless Controller is Intel(R) Wifi 6 AX203
2. The Original OS is Windows 11 Home Edition
3. Yes, all of the things are working smoothly in the Windows, I am using a dual boot so I shift back to winows often.
4.  Yes, as I was installling ubuntu I started encountering issues, like the touchpad was not working during the installation process, and I had to use a Mouse. But after the installation, it worked. And my bluetooth is also still not working.
5. SSU logs are attached.

Waiting for a positive and helpful response.
Thank you!

Hey Mike,

This driver says that it only supports Kernel version 6.16+, as I have highlighted earlier I am using Ubuntu 22.04 and the kernel version is 6.8.0-72-generic. So there's no point of me trying this.

Should I assume that as of now there's no support available for my hardware? One more thing, will I receive no assistance on the other issues that I have highlighted like display, Bluetooth etc?

Hi Samtel9,

Have you solved the Display issue? I encountered the same issue with 22.04 LTS and tried below same troubshooting.

[Quote] Display Brightness Control Not Working:

• The brightness slider appears in the system UI, but adjusting it has no effect on the screen brightness.

• The backlight control device is named "ideapad," not "intel_backlight". [same as your issue]

• My Troubleshooting: I have added the "acpi_backlight=vendor" kernel parameter to the GRUB configuration. While this enabled the slider, the functionality is absent. Manually writing a value to "/sys/class/backlight/ideapad/brightness" also has no effect. This suggests the kernel driver is not correctly communicating with the display's hardware (or so do I think).

Hello Samtel9,

Thank you for the update.

Let me confirm this and post the response on this thread once it is available.

By the way, for the display issues, kindly create a separate thread for that inquiry so that our Graphics team can take a look at the issue. 

If you have questions, please let us know. Thank you.

Hello Samtel9,

I hope you are doing well. 

Before we proceed, please note that this is an OEM device, we will try to assist you with general troubleshooting steps even if it’s something not traditionally covered in our support. However, if the issue still persists, you will have to contact the Original Equipment Manufacturer of your device. Your device manufacturer may have altered features, incorporated customizations, or made other changes to some components for better compatibility with your system."

Regarding the wireless card, Intel wireless drivers are part of the upstream Linux* kernel. They're available through the regular channels, distributions, or the Linux* kernel archives. 

To further isolate the issue, please help share the output of the following:

• # lspci​ 
• # modinfo iwlwifi​
• # lsmod | grep iwlwifi​ 
• # dmesg | grep “no suitable firmware found!"

Once done, create a separate file to get the output of the following command: # dmesg | grep iwlwifi​ 

If you have questions, please let us know. Thank you.
