Apple EFI loads, loads GRUB by default (can't > remember the exact magic incantation of Apple `bless` I used to make this > work), and then GRUB loads the Linux kernel. > > $ apt show grub2 | grep Version > Version: 2.02~beta2-21 > It is quite possible this was never actually fixed (you should get some "radeon 0000:01:00.0: Invalid ROM contents" and "[drm:radeon_get_bios] *ERROR* Unable to locate a BIOS ROM" if it doesn't work due to this). There's plenty of bugs filed all around (here's another one: https://bugzilla.redhat.com/show_bug.cgi?id=765954) with various obscure workarounds all boiling down to pretty much the same (I never tried those suggesting disabling kms, as I wouldn't describe a ums setup as "working" in any case even if you can get some display output) and I haven't seen anyone claiming it is really working now. Might be worth asking the grub guys again. Though presumably this would not fix the problem that switching soesn't work if not booted with the intel gpu active, which I presume is a problem with the i915 drm driver (but of course can be more easily "fixed" by those outb commands in the grub config). -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
