Bug Description

Binary package hint: xorg

Booted laptop after updates from yesterday to find:
(EE) NVIDIA(0): Failed to allocate video memory
(EE) NVIDIA(0): *** Aborting ***

Since then I have to run in low graphics.

  Add option "nopat" to kernel parameters.

Solved the problem by adding "nopat" to grub.cfg.
So is this the driver or the kernel? Combination of both maybe?

Same here.

Is it possible to have the nvidia debs automatically add 'nopat' to /etc/default/grub and run update-grub ?

For what's it worth, this started happening for me in Maverick, see bug 607490.

I am not sure how much these bugs are really related, but probably they are.

I can confirm that setting "nopat" in GRUB actually solves the problem for me. Strange enough, the problem with the NVIDIA card (I have a Geforce GTX 460) only appears when using x86_64 on Ubuntu 10.10. If I boot 10.10 on same hardware as 32bit installation, everything works fine.

A side node to #8. It makes a difference if I start with IOMMU enabled in BIOS or not. If IOMMU is enabled, the Nvidia card does not work. If its disabled, it works with "nopat".

Looks like this issue is still being seen on natty, after just looking at bug #731810, which I've set as a dupe of this.

It sounds like the root problem here is a bug in vesafb's memory handling when using a PAT-enabled kernel. There is some topical conversation about this at http://www.nvnews.net/vbulletin/showthread.php?t=148417

Presumably either booting with "nopat" or "vesafb.invalid=1" kernel parameters in grub should work around the bug. Disabling vesafb will also disable the boot logo graphic, fwiw.

The problem with vesafb might be solved in the latest version of grub2 in Natty.

I can confirm that the problem exists with 11.04 unmitigated. Bummer.

That version is no more supported; please open a new bug report if the actual archive found version also has the same issue.
