While playing around with various mainline kernels I found out that the vanilla NVidia driver (310.xx and 313.xx) do not compile on the linux 3.8.0-rc3 kernel. Testing the xorg-edgers and ubuntu-x-swat versions of the NVidia driver package did not help either.<\/p>\n

Until the NVidia driver officially supports the 3.8.0 kernel, this workaround will allow you to fix the NVidia driver using the DKMS source installation. This might also still apply for kernel 3.7.x. Begin by adding the ubuntu-x-swat repository to get at least version 304.60 of the NVidia driver:<\/p>\n

sudo<\/span> apt-add-repository ppa:ubuntu-x-swat\/<\/span>x-updates\nsudo<\/span> apt-get update<\/span>\nsudo<\/span> apt-get install<\/span> nvidia-current<\/pre>\n
Patch (by hand if you have to) the following 2 files:\u00a0\/usr\/src\/nvidia-current-304.64\/conftest.sh<\/code> and \/usr\/src\/nvidia-current-304.64\/nv-mmap.c<\/code>. These patches are based on 310.xx but can be used for manual modification:<\/p>\n
