First off, I’d like to admit I’m a relative noob when it comes to linux, and that I’ve ran into this same issue with Manjaro before. I attempted to boot a live image, but whenever I do, I get a “DRM:Radeon_Init” error; “No UMS support in radeon module”. I looked into this, and it appears I need to use KMS. I quickly Googled the issue and I can’t figure out what I need to do to live boot. I’d rather try the distro out before switching.
KInfoCenter says I have a “AMD Heathrow PRO [HD 7850/8850M]”
Any and all help is greatly appreciated. Thanks!
