[Bug 762855] Re: [sandybridge-m-gt2+] Display on external monitor (vga) is black on 13" MacBook Pro 8, 1 (x86_64)
Hi Dan,
Good to hear the mainline kernel solved it. Would you be willing to do
some additional testing to isolate which specific patch fixed it? If
so, the kernel team might be able to backport that fix to include in
natty.
Directions for isolating kernel patches via git bisection are documented here for you:
https://wiki.ubuntu.com/Kernel/KernelBisection
If you can find a commit where the kernel switches from failing to
working, that'll give the kernel guys a strong indication of what needs
pulled from upstream to get your system working by default with natty.
