I can't adjust the brightness on my laptop.

Hopefully helpful reference info: Device: Lenovo ThinkPad E585 CPU: Ryzen 3 GPU: AMD Radeon Vega Graphics OS ver.: Ubuntu 20.04

When I click the upper right corner and move the brightness scrubber left or right, there's no change in the actual screen brightness.

I've searched here, but links like this seem to only deal with Nvidia GPUs. Mine has a built in Radeon Vega graphics, so I'm not sure if the procedure is the same. I tried installing amdgpu-pro-install, but that gave me issues with a blank screen after reboot, so I ended up having to uninstall it afterward.

Let me know what you guys think or any more information I need to edit this post and add.

Thanks in advance!


I had a similar problem that was solved by updating to the latest linux kernel (5.7 should also be okay), which includes better support for AMD graphics. I used this guide to update my kernel to 5.8. Hope that helps!

  • I updated the Kernel to 5.8, but it still isn't working. I do appreciate the help, though! – ShadowFox Aug 23 '20 at 0:13
