I couldn't get 3.7-rc1 & 3.7-rc2 to work, so I can't do an A-B-C comparison, but I've been pushing 3.7-rc3 hard, for over 10 hours, without a single hiccup.

Oddly, Flash et al. seems to be much smoother and more stable than 3.6.x. Usually, my browser runs out of mem, several times a day, especially when I have lots of tabs open. But, I haven't had one occurence yet, with 3.7-rc3.

Since my last post (above), and with your encouragement, I went ahead and gave Linux 3.7-rc3 a whirl.

Nothing, nada! No nVidia legacy support. And, a slew of errors & warnings, just like my previous attempts.

Next, following up on Milos_SD's post, I started patching my edgers 304.51 drivers. I started with "conftest.sh".

Only one error, this time, but it was fatal. Still no nVidia legacy support.

Finally, I tried the "nv-mmap.c" patch. Bingo!!!

Third install worked a treat...

In the meantime, I guess ppl running ancient iron will have to roll your own...

I'm in the same boat. My graphics card isn't supported by the latest nvidia-current. The kernel module built ok with 3.7-rcN I think, but wasn't loadable.

I've switched to nvidia-current-updates which doesn't build at the moment with 3.7-rcN (without patching).

Will either hold out for a new version of nvidia-current-updates or look into patching it.

A few thoughts...

Evidently, my GeForce 7600GT has been deemed a legacy device, and won't be supported beyond nVidia 304.x.

Put another way, nVidia >= 310.x will never work in this rig, unless I upgrade my hardware.

The greater issue is, the VM_RESERVED flags have disappeared in kernel 3.7.x and need to be replaced (kernel patch) or ignored (nVidia patch).

I took the easy route and simply patched two (2) files in my nVidia 304.51 folder. My assumption is, as long as I don't do a fresh install of nvidia-current, e.g. not patched, I will be able to upgrade the kernel, at will.

The VM_RESERVED flags are not coming back, AFAIK. They are remapping a lot of things in kernel 3.7.x to make it compatible with upstream developments -- kmod being one of them.

Anyway, that's the *feeling* I get, from reading around in the gits.

I can live with nVidia legacy drivers, but my kernel fetish is a different matter. LoL!

Patching the nVidia install seems to be the easiest way of accomplishing this...

Here are the patches I applied:

+ vma->vm_flags |= (VM_IO | VM_LOCKED | (VM_DONTEXPAND | VM_DONTDUMP));

The first patch is a drop-in.

Make a text file. Example: uapi-patch.txt
Drop it into your nVidia folder. Example: ~/usr/src/nvidia-current-304.51
Run the patch from inside your nVidia folder with superuser privs. Example:
Code:
```
sudo patch -p0 <uapi-patch.txt
```

The second patch is a bad copy n' paste, or whatever -- couldn't get it to work -- so I manually patched it...

Edit nv-mmap.c with root auth

Find:

Code:

vma->vm_flags |= (VM_IO | VM_LOCKED | VM_RESERVED);

Replace with:

Code:

vma->vm_flags |= (VM_IO | VM_LOCKED | (VM_DONTEXPAND | VM_DONTDUMP));

Save

Having said that, I *might* try to install nVidia 304.60...

3.6.4. and 3.6.5 for raring.

But neither of those have the linux-headers-*-all.deb package.

They must have listened to you, Dino.

Ubuntu 13.04 will likely be shipping with the linux 3.8 kernel.

Kernel 3.7-rc4 is available.

Cheated death again... LoL!

**ventrical** · November 5th, 2012

Geesh !

Another one of those awesome 3D screens..!

**dino99** · November 5th, 2012

what are they doing ?

HTML Code:

drm/nouveau: headless mode by default if pci class != vga display

so if your display is not a vga one, be ready for a "no device found" or a blackscreen

very strange setting

or is it switching to nouveau driver in that case ?

**Milos_SD** · November 5th, 2012

3.7-rc4 running great for the past 11 hours. There are no memory leaks that I had with -rc3, and no a lot of iowait that I had with -rc2.

These where the culprits that messed with my audio pleasure that I' wrote about. The same conclusion...
It was fixed couple of days ago in daily... (999)...
