Hi Guys!
I would like to adjust my graphics card with "CoreCtrl" and have therefore already installed the software. To have full access you have to add the following parameters in Grub:
amdgpu.ppfeaturemask = 0xffffffff
I have already done that and then made a grub update.
However, I still don't have full access to the hidden options. What could be the problem?
Would appreciate help 
best regards
Hans_Paul_Rodriguez Solus uses the clr-boot-manager. You'll need to create a file named cmdline located in /etc/kernel
sudo nano /etc/kernel/cmdline
Type: amdgpu.ppfeaturemask=0xffffffff
Save it
Type the command sudo clr-boot-manager update and reboot. Enjoy!
Edit: They have a guide here: https://getsol.us/articles/troubleshooting/boot-management/en/
thanks alot! that solved my problem
cheers
