- Remove remaining references to XFree86-Misc options AllowNonLocalModInDev and DisableModInDev. - Remove remaining references to grab-breaking keys & associated options. - Update description of Ctrl-Alt-Backspace to new -retro/DontZap defaults. - Add description of new options -modalias and -showopts. - Update list of modules loaded by default. - Update input driver references from keyboard to evdev & kbd. - Update list of driver man pages to match xf86-*-* drivers with man pages. - Add See Also section to exa man page. and various formatting/typo/etc. fixes. The Xorg/xorg.conf sections on input device selection could use further updates to better match the current state of HAL-enabled configuration.

.SH NAME
|
|
exa \- new 2D acceleration architecture for X.Org
|
|
.SH DESCRIPTION
|
|
.B EXA
|
|
provides a simple API for video drivers to implement for 2D acceleration. It
|
|
is a module loaded by drivers, and is not intended to be loaded on its own.
|
|
See your driver's manual page for how to enable
|
|
.BR EXA .
|
|
.PP
|
|
The
|
|
.B EXA
|
|
architecture is designed to make accelerating the Render extension simple and
|
|
efficient, and results in various performance tradeoffs compared to XAA. Some
|
|
__xconfigfile__ options are available for debugging performance issues or
|
|
driver rendering problems. They are not intended for general use.
|
|
.TP
|
|
.BI "Option \*qEXANoComposite\*q \*q" boolean \*q
|
|
Disables acceleration of the Composite operation, which is at the heart of
|
|
the Render extension. Not related to the Composite extension. Default: No.
|
|
.TP
|
|
.BI "Option \*qEXANoUploadToScreen\*q \*q" boolean \*q
|
|
Disables acceleration of uploading pixmap data to the framebuffer. Default: No.
|
|
.TP
|
|
.BI "Option \*qEXANoDownloadFromScreen\*q \*q" boolean \*q
|
|
Disables acceleration of downloading of pixmap data from the framebuffer.
|
|
.B NOTE:
|
|
Not usable with drivers which rely on DownloadFromScreen succeeding.
|
|
Default: No.
|
|
.TP
|
|
.BI "Option \*qMigrationHeuristic\*q \*q" anystr \*q
|
|
Chooses an alternate pixmap migration heuristic, for debugging purposes. The
|
|
default is intended to be the best performing one for general use, though others
|
|
may help with specific use cases. Available options include \*qalways\*q,
|
|
\*qgreedy\*q, and \*qsmart\*q. Default: always.
