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. -</itemize> - - -<sect>Configuration -<p> -The driver auto-detects all device information necessary to -initialize the card.

The driver - will fail to recognize them, and only function through VGA output. Two - partial DVO chip drivers (ivch and ch7017) are included which contain some of - the code necessary for i830 laptop panel support, but some I2C debugging will - be necessary to get those drivers to attach. - <item>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. - <item>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. - <item>i855 XV may cause hangs. This was present in the previous release, - and no workaround is known. - <item>SDVO TV-out cards not supported. This should be fixed in the next - release. - <item>Gray output with integrated TV-out. - <item>EXA support unstable on i845. -</itemize> - -<sect>Common issues not caused by the driver -<itemize> - <item>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. - <item>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. - <item>Older resolution-changing applicationss 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. - <item> -</itemize> - -<sect>Author -<p> -<itemize> - <item>Eric Anholt - <item>Keith Whitwell -</itemize> - -The X11R&relvers; version of this driver originally came from XFree86 4.4 rc2. - -The XFree86 version of this driver was donated to The XFree86 Project by: -<verb> - Precision Insight, Inc. - Cedar Park, TX - USA -</verb> - -The X.Org version of this driver is maintained by Intel Corporation. - -<htmlurl name="http://www.intellinuxgraphics.org" - url="http://www.intellinuxgraphics.org"> - - -</article> |
