The driver supports hardware accelerated 3D via the Direct Rendering Infrastructure (DRI), but only in depths 16 and 24. User mode setting (UMS) Linux X.Org driver
Note that this is no longer an option starting with version 2.10 of the Intel Xorg driver as UMS support has been dropped. If KMS causes you problems, you can disable it and return to user mode setting (UMS) by booting with the nomodeset kernel boot option. In this mode, ideally you do not configure any settings through nf but by using xrandr, or a graphical front-end to RandR such as gnome-display-settings. There is a bug in the Intel KMS driver, fixed in kernel 2.6.38, where you get 'random' memory corruption if you have this model Intel video chip, >4GB of memory and hotplug an external display. But in reality you should really be running at least the 2.6.30.5 kernel and version 2.8 of the Intel driver. Right now KMS is still in heavy development, and officially requires at least kernel 2.6.29 with version 2.7 of the Intel driver. Note that KMS does not eliminate the need for the Intel Xorg driver, it just frees that driver from the hardware setup functions. should in the future allow for the X server to run without root privileges.early graphical boot display with seamless login.in theory should not allow the X video driver to hang the system.ability to show kernel dump screens even when the X server was running.increased stability, because it removes the current contention between the X server and the kernel.This should have the following benefits over legacy mode setting KMS (Kernel Mode Setting) as the name suggests moves some video setup functions to the kernel. Intel releases a new driver once per quarter. The Intel opensource videodriver is maintained by Intel at.
Uses part of main memory for video usage.Integrated into the following chipsets:.
