It seems that is set to GRUB_GFXMODE=1024x768x32 but the actual mode is set to 1024x768x24 ? That is, it fails when the picked format is DRM_FORMAT_RGB8888 but works when is DRM_FORMAT_XRGB888. I can't spot any error in Thomas' patch so I wonder if the problem is with what grub is passing to the kernel. The mentioned vga=0x318 workaround that you mentioned makes the mode passed to match the selected DRM_FORMAT_RGB888 which I guess is why that worked for you. -- Best regards, Javier Martinez Canillas Core Platforms Red Hat
