Issue/Bug Description:
Pop!_OS 22.04 boot to black screen unless radeon.modeset=0 is set on GRUB_CMDLINE_LINUX_DEFAULT. If I boot with radeon.modeset=0 system loads to the desktop using iGPU but I cant use the dGPU.

Expected behavior:
It should boot OK using the iGPU and keep the dGPU ready to use.

I don't know if this is the right place to report it, if it is not, I hope you can guide me.

Thanks
