Same thing happening here sice a week or two ago. The only way to recover is a hard shutdown :(

Saw some Nvidia errors in the logs, upgraded to the new proprietary tested 535 Nvidia drivers, but...

Hi,

I have a similar problem. Any ideas about what could be the cause?

OK, problem solved. With 12.10 I had to:

sudo apt-get install linux-headers-3.5.0-17-generic
sudo apt-get remove virtualbox-dkms
sudo apt-get install virtualbox-dkms

And then, in VBox, go to...

Any news for 12.04?

This thing is a battery killer!

Just found out about Ironhide... but is seems there is no support for Macbook Pro 5,3 or similar... https://launchpad.net/~mj-casalogic/+archive/ironhide/

There is a bug report on this... if we all mark it as affecting us maybe things will move faster:

Any news regarding a simplified (aka PPA or similar) way to enable 9400M in Oneiric?

The solid >62º I am getting in my MBP5,3 are killing me (and the battery).

Also, the affected people can...

Thanks metatechbe.

Yes, I did kill v86d and waited for a while. Even when leaving the computer alone (doing nothing), the temperature never goes under 44º. Using the computer in normal browsing...

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"...

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...

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...

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:

Thanks!

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.

Any news out there? Someone managed to use his/her dual GPU laptop using the 9400?

Hi, mine says exactly the same:

<"MacBookPro5,3">
FrameBufferBase: 0xd0010000


Although, I needed sudo privileges for the second line.

Wow, thanks metatechbe. It seems you are moving forward... Keep up the great work!

If you manage to do it you'll be my hero ;)

Guys, I opened a bug related to this to try to give it more visibility:

Maybe you could share your progress there...

dromiceiomimus, how did you put it in low power mode?

Thanks.

Yes, please, someone out there tried it and got it?

It would be great to have a clear and simple howto.

Gelliray, did you manage to get 9400 working?

Thanks

Apparently our problems will be solved using 2.6.34 kernel

Any news on activating Nvidia 9400 on dual 9400/9600 systems? Still nothing in Lucid.

I've found this thread in the Gentoo forums that maybe can be helpful:...

Any advances here or we are stuck with .17?

In .18, .19 and .20 still no sound.

Tried the backports and compilation with no luck.

In my case, AlsaMixer shows nothing.

Thanks for the info about fonts. That is a part of the problem but my main problem is sheer compatibility: tables not remembering their position, problems with pictures, tables formating...
