It's odd that kms is not supported for radeon. There's is no answer to why it's not supported.
Because it is supported. Why do you think it isn't? Maybe you have one that requires unavailable firmware? I have several radeon cards. All are supported by KMS.
You would think by now that the we shouldn't have to add a video= entry in the kernel option. It should be auto-detected.
KMS does autodetect EDID provided modes, and selects EDID preferred mode unless directed otherwise, and AFAICT, also autodetects what modes the gfxchip supports. How such autodetection and autoselection interplays or not with Plymouth in openSUSE I don't know, because all openSUSE installations here have Plymouth tabooed.
My screen gets auto-detected in Plasma 5. However, this doesn't get passed on to the boot splash.
Most people don't need video=. Grub2 has an entirely separate and less simple mechanism for configuring itself and what it passes on to what follows. Grub2 needs neither vga= nor video=. AFAICT, it doesn't pass vga=, and even if it does, KMS overrides it. What it does or not with video= I don't know. I don't use Grub2 much, and not at all with openSUSE. -- "The wise are known for their understanding, and pleasant words are persuasive." Proverbs 16:21 (New Living Translation) Team OS/2 ** Reg.
