This document provides a brief summary of the Intel graphics support provided
|
|
by the xf86-video-intel driver. More information can also be found in the
|
|
<htmlurl name="i810(4)" url="i810.4.html"> manual page.

<sect>Features
|

<p>
|
|
<itemize>
|
|
<item>Full support for 8, 15, 16, and 24 bit pixel depths.
|
|
<item>Hardware accelerated 2D drawing engine support for 8, 15, 16 and
|
|
24 bit pixel depths.
|
|
<item>Hardware accelerated 3D drawing using OpenGL and the DRI.
|
|
<item>Hardware cursor support to reduce sprite flicker.
|
|
<item>Textured video XV implementation on i915 through i965.
|
|
<item>Hardware overlay XV implementation up through i945.
|
|
<item>Screen resize and rotation on chipsets up through i945.
|
|
<item>Screen resize on i965.

|
<sect>Technical Notes
|
|
<p>
|
|
<itemize>
|
|
<item>Interlace modes cannot be supported.
|
|
<item>This driver requires kernel support for AGP, which is
|
|
included in Linux kernels 2.3.42 and higher, and FreeBSD 4.1
|
|
and higher.
|
|
</itemize>
|
|
|
|
|
|
<sect>Configuration
|
|
<p>
|
|
The driver auto-detects all device information necessary to
|
|
initialize the card. The only lines you should need in the "Device"
|
|
section of your xorg.conf file are:
|
|
<verb>
|
|
Section "Device"
|
|
Identifier "Intel i810"
|
|
Driver "i810"
|
|
EndSection
|
|
</verb>
|
|
|
|
In order to use most resolutions, it is necessary to install the
|
|
"agpgart.o" module. You will probably have to compile the module yourself
|
|
(see the notes in the module).

<sect>Driver Options
|
|
<p>
|
|
Please refer to the <htmlurl name="i810(4)" url="i810.4.html"> manual page
|
|
for information on configuration options.

|
|
<sect>Known Limitations
|
|
<p>
|
|
<itemize>
|
|
<item>Many systems with Intel graphics have issues with setting video modes
|
|
at larger than some small maximum resolution. This is not fixed in the current
|
|
release, but is being actively worked on in the modesetting branch.
|
|
<item>Bug #5795: Some systems have issues with VT switching. This should
|
|
be fixed with the modesetting brach integration.
|
|
<item>Bug #5817: Hotkey switching from LVDS to CRT breaks CRT output. This
|
|
is a known issue, but will not be fixed in the current release.
|
|
<item>Bug #6635: Video is output from an incorrect offset in the framebuffer.
|
|
This is expected to be fixed with the modesetting branch integration.
|
|
<item>GL_EXT_texture_compression_s3tc is not supported. We can't support the
|
|
extension due to patent restrictions on compression, but may be able to support
|
|
an option for partial extension support in the future. For now, this prevents
|
|
Quake4 and some other games from running.
|
|
<item>Some X Test Suite cases sometimes fail due to a timeout. These cases
|
|
include: Xt8/XtResizeWindow, Xt8/XtQueryGeometry, Xt9/XtAppAddInput,
|
|
Xt9/XtRemoveInput, Xt9/XtAppAddTimeOut, Xt9/XtRemoveTimeOut, Xt9/XtAddGrab,
|
|
Xt9/XtRemoveGrab.
|
|
<item>Some X Test Suite cases fail in 64-bit mode: Xlib9/XDrawArc,
|
|
XDrawImageString, XDrawLine, XDrawRectangle, XDrawSegments, XFillArc,
|
|
XFillPolygon, XFillRectangle, XPutImage, Xt11/XtVaGetSubresources,
|
|
XtSetSubvalues, and XtVaSetSubvalues.
|
|
<item>Some GLEAN test cases fail if DRI is enabled: pointAtten,
|
|
readPixSanity, texCombine, texCube, texEnv, texgen, coloredTexPerf2, and
|
|
coloredLitPerf2.
