#Brightness control stuck on screen windows#
When using only the discrete graphics card the brightness control works perfectly. Use the keyboard shortcut Windows + A to open the Action Center, revealing a brightness slider at the bottom of the window. times just got me from the screen I was stuck on to the main display. It is worthy to note that the value of /sys/class/backlight/amdgpu_bl0/actual_brightness is stuck at 311 and does not change at all. Since there is no control to adjust screen brightness, I was wondering if it is. Now try to change the brightness with software, Fn keys and changing /sys/class/backlight/amdgpu_bl0/brightness and the brightness will not change, i.e The brightness control will not respond and the brightness will always be at max. By default the panel uses iGPU for everything and offloads large graphical apps to dGPU. The f2 and f3 keys make the brightness go up and down as normal and the slider flashes a bit but the on screen slider does no go away. Now you should have AMD iGPU and NVIDIA dGPU enabled. Every time I boot the conputer the brightness control/slider is stuck on the screen and will not go away. Afterwards the desktop simply doesnt work properly windows cant be moved console doesnt get the focus when clicked keyboard doesnt work. AMD package version: 19.1.0-3.3 (xf86-video-amdgpu)Įnable Switchable Graphics from BIOS and restart. When brightness increase/decrease keys (Fn+up/down arrows) are pressed even only once, the brightness increases/decreases continuously until its max/min (like the keys are stuck).Distro name and Version: OpenSUSE Tumbleweed.CPU: AMD Ryzen 7 4800H with Radeon Graphics.Brightness control somewhat worked with Fedora Workstation 32 with Linux Kernel 5.6.6 but now with 5.10.4 brightness control does not work. Brightness control only works with discrete graphics card. The value of /sys/class/backlight/amdgpu_bl0/actual_brightness is stuck at 311. Can iPhone 12 do split screen Yes, the iPhone 12 will.
Brightness control does not work with AMD Ryzen 4800H Renior iGPU when using switchable graphics (aka. Tap and hold the slide to adjust brightness slider, then release it and tap the split screen button.
