I just installed the latest 5.11 kernel along with the latest update that came after the reboot.Īnd it solved the trackpad issue (it works!) but the brightness still can't be adjusted.īelow is the updated info spec of the hardware. I also noticed that helped splitting the thread into a different topic. Install the kernel and then reboot for it to become active. Make sure 5.11 is selected on the left panel and then click the top-most option on the right panel. Select View > Linux Kernels and click Continue. Your system has a 4th-gen Ryzen which means you should be using the 5.11 kernel available in Update Manager. Forum rules indicate you should create your own thread.

Recently, I encountered a weird problem in Windows 7, my screen brightness was stuck to maximum setting.
