Screen brightness stuck on 35% after switching to dGPU
Hi everyone, I hope you are all doing fine this evening. I'm struggling to fix a problem on my laptop whenever I switch to my dGPU via supergfx. The screen brightness won't change via KDE's brightness slider nor the FN keys. I've read that this is a known issue with laptops equipped with hybird graphics on github, I tried the commands on the github article but they never worked. Any help with resolving this issue is greatly appreciated. Thank you and have a good night. Here is my fastfetch output incase anyone needs it.
