Metatechbe, it would be possible for you to post a step by step guide starting with a clean system?

It would be great to have the guide here in the forums and also, include it in the bug report.

Thanks!

Metatechbe, I am following the step by step guide and I am having problems in one of the steps. According to the guide, in the Installing GRUB section you have to run the following two commands:

cd grub-core
../grub-mkimage -O $EFI_ARCH-efi -d . -o grub.efi -p "" part_gpt hfsplus fat ext2 normal chain boot configfile linux multiboot

I am in ~/grub/grub-core/ but the last command gives me an error:

bash: ../grub-mkimage: No such file or directory

Should I create manually the directory? Any ideas?

Thanks a lot.

Are you sure you are using grub 1.99 RC1 ?

I followed the guide so I got GRUB using:

bzr branch --revision -1 http://bzr.savannah.gnu.org/r/grub/trunk/grub

Also, in the NEWS file it says: "New in 1.99:" so it should be 1.99...

Are you sure you are using grub 1.99 RC1 ?

OK. I started all over again and this time the error (in the same step "../grub-mkimage -O $EFI_ARCH-efi -d . -o grub.efi -p "" part_gpt hfsplus fat ext2 normal chain boot configfile linux multiboot") changed to:

unknown target format -efi
Try `../grub-mkimage --help' for more information.

Any ideas?

Thanks.

OK, this is probably my own fault. Using this I managed to advance:

../grub-mkimage -O x86_64-efi -d . -o grub.efi -p "" part_gpt hfsplus fat ext2 normal chain boot configfile linux multiboot

OK. I started all over again and this time the error (in the same step "../grub-mkimage -O $EFI_ARCH-efi -d . -o grub.efi -p "" part_gpt hfsplus fat ext2 normal chain boot configfile linux multiboot") changed to:

unknown target format -efi
Try `../grub-mkimage --help' for more information.

Any ideas?

Thanks.

OK. Finally everything worked, sort of.

I had to modify the menu entries for grub.cfg as my / partition is sda5 instead of sda3... so, if anyone gets a "noinit found. Try passing init= bootarg" error, it might be this.

Another quirk is that when the system boots, a process named v86d is using 100% cpu...

Finally, the temperature, as reported by NVIDIA X Server Settings is about 50º, not 42º as expected.

Suspend/resume works but after resuming, the temperature goes up to >57º. I tried to use gpupwr but the following error appears:
ioperm failed
Segmentation fault

Brightness does not work, as advertised.

Other than that, great work guys.

Finally, the temperature, as reported by NVIDIA X Server Settings is about 50º, not 42º as expected.

After 10-20 minutes after boot, the temperature should be around 40-42 degrees Celsius. Did you kill the v86d process and waited long enough for the machine to stabilize its temperature ?

You need to run the gpupwr command with "sudo"
