--- Comment #20 from Seth Forshee <seth.forshee at canonical.com> --- Okay, thanks. I suspect at least part of the problem may be related to efifb. I don't see that it's being used on your machine, and I note that it has a bunch of quirks for making it work with various Mac hardware. If we add a quirk for your machine efifb should then be able to identify the radeon as the default vga device and use it for the console framebuffer. I'm guessing this won't fix the problem with the 32-bit builds, but it should at least remove the need for i915.disable=1 with the 64-bit build. To make a patch I'll need some DMI information for your machine. Could you send me the output from the following commands? dmidecode -s bios-vendor dmidecode -s system-product-name -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
