recently I upgraded my motherboard (ASUS M5A97 Evo R2.0, 970 Chipset with new UEFI Bios) and CPU (AMD FX-8350).
And now I detected following problem: I have a Radeon R9 270X grafik card. This card won’t work with KMS support in kernel enabled. Won’t work means: the installer is freezing. With the old bios this wasn’t a big deal, because I was able to added the grub option nomodeset, or later there was already a grub menu “no KMS” or something like this available.
So at the moment I won’t be able to reinstall OpenSuse on my computer because I cannot tell the installer to not use kms.
I’st question is: why? Maybe it’s because the boot loader is signed and cannot be modified. hmmm.
Second question is: Is there a solution? I’m not in hurry since my existing installion is still working. But I wan’t to know how it would be possible to reinstall, or upgrade my openSuSE. Of course I can replace my grafik card by something that is supported and replace it again later after installation, but that’s not a smooth solution.
