More information can also be found in the -intel(4) manual page. +What is xf86-video-intel +------------------------ +The xf86-video-intel module is an open-source 2D graphics driver for +the X Window System as implemented by X.org. It supports a variety of +Intel graphics chipsets including: -Supported Hardware: - i810, - i810-dc100, - i810e - i815 - i830 - i845 - i852 - i855 - 915G - 915GM - 945G - 945GM/GME - 946GZ - G965 - GM/GME965 - G33/Q33/Q35 + i810/i810e/i810-dc100,i815, + i830M,845G,852GM,855GM,865M, + 915G/GM,945G/GM/GME,946GZ + G/GM/GME965, + G/Q33,G/Q35,G41,G/Q43 + G/GM/Q45 -Features -- Full support for 8, 15, 16, and 24 bit pixel depths. -- Hardware accelerated 2D drawing engine support for 8, 15, 16 and 24 bit - pixel depths. -- Hardware accelerated 3D drawing using OpenGL and the DRI. -- Hardware cursor support to reduce sprite flicker. -- Textured video XV implementation on i915 through i965. -- Hardware overlay XV implementation up through i945. -- Screen resize and rotation. +Where to get more information about the driver +---------------------------------------------- +The primary source of information about this and other open-source +drivers for Intel graphics is: -Technical Notes -- Interlace modes cannot be supported. -- This driver requires kernel support for AGP, which is included in Linux - kernels 2.3.42 and higher, and FreeBSD 4.1 and higher. -- This driver may be built against xserver 1.2.0 or newer. If built - from git source against an older server, a copy of xserver 1.3.0 source is - needed to complete the build, which is chosen with the --with-xserver-source - argument to ./configure. The compatibility mode with xserver 1.2.0 will have - limited functionality, in particular by not supporting RandR 1.2 or the - new Damage 1.1 updated needed for 3D applications to work with display - rotation. + http://intellinuxgraphics.org/ -Configuration +Documentation specific to the xf86-video-intel driver including +possible configuration options for the xorg.conf file can be found in +the intel(4) manual page. After installing the driver this +documentation can be read with the following command: -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: + man intel - Section "Device" - Identifier "intel" - Driver "intel" - EndSection +Mailing list for communication with users and developers of +xf86-video-intel: -Please refer to the intel(4) manual page for information on configuration -options. + intel-gfx@lists.freedesktop.org. + Note: Subscription is required before posting, but anyone is + free to subscribe. See instructions (and archives) here: -Known Limitations -- No support for "zaphod mode" dualhead. This is the mode in which two - Device sections are placed in the config file, and doesn't support DRI or - many other features. Instead, only "MergedFB-style" dualhead is supported. -- No support for X Screens larger than 2048 pixels in either direction - before the 965. This reflects hardware limitations in the x direction on - those older chips, and limits dualhead functionality. It may be possible to - extend the limit vertically on these older chips. -- i855 XV may cause hangs. This was present in the previous release, and no - workaround is known. -- SDVO TV-out cards not supported. This should be fixed in the next - release. -- Gray output with integrated TV-out and PAL TVs. -- EXA support unstable on i845. -- Some GM965 systems, such as the Thinkpad T61, probe the TV as being connected - even when no output connector is available. This results in the gnome-panel - issue noted below. + http://lists.freedesktop.org/mailman/listinfo/intel-gfx -Common issues not caused by the driver -- Font sizes (DPI) are wrong. Some displays incorrectly report their - physical size, which is harmless on most OSes that always assume 96dpi - displays. This can be fixed through quirks for specific monitors in the X - Server, and the output of xrandr --prop along with a physical measurement of - the screen size in a bug report against the server can help get that fixed. -- gnome-panel is located in the middle of the screen. gnome-panel places - itself within head #0's boundaries, which doesn't work well with a second - head covering the same area as head #0 but larger. -- Older resolution-changing applications have poor results in - multihead systems. Previous extensions such as RandR 1.1 exposed only a - single output to client programs, and those requests map poorly to multi-head - systems. Currently, those requests map to just one of the outputs in the - RandR 1.2 environment, and those applications need to be updated to RandR 1.2 - API when available for better results. +To report bugs encountered with the driver: -The X11R6 version of this driver originally came from XFree86 4.4 rc2. + http://bugs.freedesktop.org -The XFree86 version of this driver was donated to The XFree86 Project by: - Precision Insight, Inc. - Cedar Park, TX - USA + Product: xorg + Component: Driver/intel -The X.Org version of this driver is maintained by Intel Corporation. -<http://www.intellinuxgraphics.org> +To see bugs that are targeted to be fixed in the next release: + + https://bugs.freedesktop.org/show_bug.cgi?id=intel-2d-release |
