    You ever got sleep working? I have pretty much the exact same hardware as you (except for 5850 GPU), and the iATKOS ML2 worked perfectly for me with regards to sleep (had to use a new VoodooHDA to get audio working. However, since I have a retarded M-Audio Firewire 410 audio card with no drivers for ML, I'm now trying out Lion instead. Works great with iATKOS, except for sleep. (And the same dealie about audio, solvable by the same VoodooHDA download). I'm trying different kexts with #####, but can't get sleep to work. I also have a different BIOS revision (1202), since I've SLIC'ed it for Windows 7 and don't want to lose that by ugrading.

    Making gptsync in rEFIt play nice with Filevault 2 for dual boot

    Okay, so I'm now up and running. What I did was basically make a backup of the existing partition table using gdisk from my Ubuntu live stick. I then installed bless (not to confuse with bless on OS X — on Ubuntu it's a hex editor ) and manually changed the garbled FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF GUID for the correct one, saved it and used gdisk again to restore the GPT on disk from the one I just edited. It'll complain that the CRC is not matching, but being gdisk, it'll just fix it when you save. Mac OS X would now boot, and rEFIt would recognize the partition as Apple CoreStorage, but still it wouldn't touch the disk, claiming "Analysis inconclusive". As rEFIt already can't properly create a working hybrid MBR in my case (it just picks up the first four GPT partitions and makes them the MBR partitions, which isn't good in my case, because my boot partition is #5 and my Linux cipher device is partition #6), I just thought, "Well f**k you then," and booted back into my Ubuntu live environment, where I used gdisk to manually create my hybrid MBR. At least it lets me pick which partitions go in the MBR. Now everything works, but I'm left wondering what the point of rEFIt really is, besides some kind of miniscule rescue environment if you don't want to use a Linux live environment or similar. Not once in this process of installing Kubuntu have I actually used rEFIt for anything — all it's been contributing with is making me do risky partitioning to accomodate it, make boot times longer and work hard to accomodate it to do what... Nothing in the end. The regular Apple EFI boot screen already offers me to boot into all recognized partitions on both internal and external storage, so it's not like I need it for triple-booting either. Am I missing something? It just seems like a piece of software made for previous generation of Macs that didn't do dual- or triple- or quadruple-booting on their own. Well, anyway, don't think I'll bother removing it either. It's just a 64 MB partition squeezed in between my filevault partition and my Linux ones. It can stay there if it likes

    Making gptsync in rEFIt play nice with Filevault 2 for dual boot

    Hmmm, okay. I think I now know why rEFIt won't touch my disk. My FileVault partition has a somewhat - ahem - different GUID: Command (? for help): i Partition number (1-6): 2 Partition GUID code: FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF (Unknown) Partition unique GUID: 00003C8E-06B9-0000-C45A-0000EE5C0000 First sector: 409640 (at 200.0 MiB) Last sector: 448297871 (at 213.8 GiB) Partition size: 447888232 sectors (213.6 GiB) Attribute flags: 0000000000000000 Partition name: 'Macintosh HD' Why the fudge would it be like that? That looks like an error. Can't say that I'm 100% sure this is the original GUID given to the partition by Mac OS X, but it's not given by the Kubuntu installer. I backed up the GPT before installing, but after using gparted to add two partitions for Linux in the empty space. So gparted might've messed up something here. I'm gonna try to see if I can manually alter the GUID using gdisk or another tool.

    Making gptsync in rEFIt play nice with Filevault 2 for dual boot

    Hi I was wondering if I could ask for your help in regards to the hacked gtpsync.efi you posted here. Anyway, I've created a couple of rEFIt boot options (a small internal partition on my SSD, and a USB stick just to be sure) with your gptsync.efi embedded. Thing is, rEFIt still says it won't touch the disk because of the "unknown" partition that is my CoreStorage cipher device. It's like I never copied your file to the rEFIt installation, except I just confirmed that I did. Your file has an md5 of f24c268f93c3e4bdb6298ec18f696e77 while the original from rEFIt 0.14 has an md5 of 9d014c1ac440be83908cc46032a7e8b0. So I can say most definitely that your gptsync.efi is the one on my rEFIt boot partition at /efi/tools/gptsync.efi. I've managed to be able to boot into Linux by using gdisk in a live cd to create a hybrid MBR, but I'm unable to boot Mac OS X. I get the password prompt, then Apple logo and the spinning wheel. Eventually the Apple logo becomes the no-smoking-minus-the-cigarette sign, and the system hangs. Any idea what might be wrong? Thank you Daniel
