I was happily using overdrive on my RX 560 and made some changes to grub and it doesn’t work anymore. I made changes to grub with grub-customizer and then ran the grubby command to add the parameter amdgpu.ppfeaturemask=0xffffffff to the kernel but even though these steps have worked before it is not the case anymore.
/etc/default/grub
GRUB_TIMEOUT=“0”
GRUB_DISTRIBUTOR=“$(sed ‘s, release .*$,g’ /etc/system-release)”
GRUB_DEFAULT=“0”
GRUB_DISABLE_SUBMENU=“true”
#GRUB_TERMINAL_OUTPUT=“console”
GRUB_CMDLINE_LINUX_DEFAULT=“resume=UUID=90416566-7972-4322-96dc-722d764f06cb amdgpu.ppfeaturemask=0xffffffff rhgb qui
et splash”
#GRUB_DISABLE_RECOVERY=“true”
GRUB_SAVEDEFAULT=“false”
GRUB_GFXMODE=“1920x1080”
GRUB_HIDDEN_TIMEOUT=“5”
I set the parameter alone and it worked! Using grub cutomizer though GRUB_ENABLE_BLSCFG to false it seems like is not set in the etc/default/grub file, that’s weird. Ihave that to false because I want to set a background image.
