#How to install intel graphics driver in centos 7 driver

The i915 driver is used with the Intel Xorg driver, as well as its alternative, the modesetting Xorg driver. Some writers for various sites clearly have the idea that i915 is the Intel Xorg driver, but it’s not. What this means is that if you are using the “modesetting” driver for Intel graphics, you are actually using the i915 driver for the kernel end, the modesetting driver (that is part of the kernel) for X or Wayland, and the i965 driver for Mesa, which implements the graphics APIs like OpenGL. That driver has long been the i965 driver that is included as part of Mesa. It also uses another open-source Intel driver for Mesa, the open-source graphics library that handles things like OpenGL and Vulkan. Like the “Intel” X driver, it uses the i915 kernel module.

For newer hardware, the preferred X driver is the “modesetting” driver, which is built into the kernel itself. Newer Ubuntu-based distros do not come with the “Intel” X driver installed on newer hardware, though it is still available in the repo.

The “Intel” X driver uses its own acceleration methods, with the most advanced being SNA, for Sandy Bridge’s New Acceleration (showing how old it is), and forms the graphic stack along with the X server and OpenGL (which is a free software equivalent of Direct3d in Windows). Some people use it now, but it’s a work in progress. It’s still in use on many, probably most, Linux desktops now (mine included), but it’s showing its age, and the goal is for it to be replaced by Wayland, the next generation graphics subsystem. This driver works with the i915 kernel module to enable the X server, which previously handled all of the video output as well as user input in Linux. This driver is known as xserver-xorg-video-intel in the Ubuntu repo. Older Linux distros used to come with the “Intel” Xserver driver. It’s distributed with the kernel, and is used by all Intel Linux setups. The kernel driver for Intel hardware is called i915. If you don’t want to tweak anything, you can just use what the distro provides, but you also have the choice to try other things! It’s the same with Intel, but the users are more exposed to the inner workings since it’s not a secret.

A graphics driver such that nVidia releases actually has a bunch of different drivers within it, not just one. I’ve tried to learn what the real deal is with the many different Intel driver bits that are around. This led to the famous image of Linus Torvalds giving a gesture of an avian variety to nVidia as a whole. It’s nVidia that continues to plow ahead with closed source everything, refusing to cooperate with open-source devs, making the nVidia open drivers pretty close to unusable for many GPUs. With Intel, there are no closed source drivers… all of the work Intel does to create drivers is open source, and I think that has been true of AMD (graphics) as well for a while too. With a closed-source driver like the ones offered by nVidia, everything is included in the downloadable driver package. There is a lot of misinformation out there about the various driver bits. For devices that are plugged into the laptop’s HDMI or other graphics port, those may be connected directly to the dGPU without going through the Intel iGPU.įor Intel graphics users, the situation can be confusing. This is the usual configuration for nVidia laptops while using the laptop display.

The G3 also has an nVidia dGPU (discrete GPU), which uses Optimus (Windows) or Prime (Linux) technology to deliver rendered frames across the PCIE bus to be displayed by the Intel iGPU (integrated GPU).

Intel graphics, though, I do have a bit of experience with, as my Swift and my G3 (Dell) both use it. It’s probably nice for AMD graphics users too, but I haven’t seen that, so I know very little about it.
