Can't launch on Fedora due to kernel parameter not working

[binarydepth]

Distro: Fedora 31 KDE spin Python 3.7.5 EFI boot

Terminal: python3 run.py The overdrive functionality seems not enabled on this system. This means WattmanGTK can not be used. You could force it by flipping the overdrive bit. For this system, it would mean to set amdgpu.ppfeaturemask=0xffffffff Please refer to https://github.com/BoukeHaarsma23/WattmanGTK#FAQ on how to set this parameter

/etc/default/grub

hello, try this GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.ppfeaturemask=<the suggested value by WattmanGTK>"

# grub2-mkconfig -o /etc/grub2-efi.cfg reboot
