Updating drivers in ubuntu

13 Feb

It is speculated that the bug has existed since 2004; Nvidia have denied this, asserting that the issue was only communicated to them in July 2006 and the 2004 bug was a bug in X. Binary drivers often do not work with current versions of open-source software, and almost never support development snapshots of open-source software; it is usually not directly possible for a developer to use Nvidia's or ATI's proprietary drivers with a development snapshot of an X server or a development snapshot of the Linux kernel.I want people to know that when they use binary-only modules, it's their problem".Another kernel developer, Greg Kroah-Hartman, has said that a binary-only kernel module does not comply with the kernel's license (the GNU General Public License); it "just violates the GPL due to fun things like derivative works and linking and other stuff." Writer and computer scientist Peter Gutmann has expressed concern that the digital rights management scheme in Microsoft's Windows Vista operating system may limit the availability of the documentation required to write open drivers, since it "requires that the operational details of the device be kept confidential." When applications such as a 3D game engine or a 3D computer graphics software shunt calculations from the CPU to the GPU, they usually use a special-purpose API like Open GL or Direct3D and do not address the hardware directly.When no technical documentation is available, an understanding of the underlying hardware is often gained by clean-room reverse engineering.Based on this understanding, device drivers may be written and legally published under any software license.

Projects such as libhybris harness Android device drivers to run on Linux platforms other than Android.

Device drivers are the abstraction layer between software concepts and hardware circuitry.
