[xubuntu-users] nVidia driver - Problem report on every reboot

Hi,
this is normal when using closed binary drivers.

Basically it's telling you that since you are using closed drivers, don't
expect the kernel developers to be interested in any problems you have.

The problem is that Nvidia does not release it's driver code under GPL or
any license that Ubuntu devs can modify. Ubuntu supplies these drives as is
without any modifications they either work or don't fortunately most of the
nvidia ones do :)
Good Luck
