Thanks for attaching the log. On line 556 there is: [ 0.502730] simple-framebuffer simple-framebuffer.0: [drm] *ERROR* fbdev: Failed to setup generic emulation (ret=-22) That's most likely because the video= resolution is not the one that grub uses. So simpledrm could not enable it. Yeah, as I said in comment 44: simpledrm shoudl probably ignore the parameter or provide a fallback.
