--- Comment #24 from Seth Forshee <seth.forshee at canonical.com> --- Created attachment 73542 --> https://bugs.freedesktop.org/attachment.cgi?id=73542&action=edit Add quirk to efifb for iMac 12,1 Here's a patch to try. But after some more poking around I'm wondering why this is needed. The kernel seems to get the information about the GOP framebuffer for most recent Macs without quirking, so it makes me wonder why it doesn't work on this machine. Just to check one obvious point, are you either running with the stock Ubuntu kernels or else with CONFIG_FB_EFI=y? An easy way to verify this is to boot the machine and run 'grep CONFIG_FB_EFI /boot/config-$(uname -r)'. This should output 'CONFIG_FB_EFI=y' if your kernel is configured to include the EFI framebuffer support. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
