This file describes how to set up kwin_composite.
|
|
|
|
See file HACKING for details on developing KWin, including building
|
|
the kwin_composite branch.
|
|
See file COMPOSITE_TODO for a list of things that still need to be done.
|
|
See effects/howto.* for a HOWTO on writting effects.
|
|
See documentation in source (mainly in scene.cpp) for description
|
|
of the design of the compositing framework.
|
|
|
|
Using kwin_composite branch:
|
|
============================
|
|
|
|
See the KDE trunk HOWTO at http://developer.kde.org/build/trunk.html .
|
|
|
|
The simplest way to build the kwin_composite branch is to switch the trunk version
|
|
to the branch:
|
|
|
|
$ cd kdebase/workspace/kwin
|
|
$ svn info
|
|
(prints the repository URL, for example https://svn.kde.org/home/kde/trunk/KDE/kdebase/workspace/kwin)
|
|
$ svn switch https://svn.kde.org/home/kde/branches/work/kwin_composite
|
|
(i.e. replace trunk/KDE/kdebase/workspace/kwin with branches/work/kwin_composite)
|
|
$ make
|
|
(i.e. build and use it as usually)
|
|
|
|
After starting, KWin's debug output also says which compositing backend it uses, e.g.
|
|
"OpenGL compositing". If it does not, most probably your X is not configured properly.
|
|
|
|
|
|
nVidia:
|
|
-----------
|
|
|
|
Both 9xxx and 8xxx drivers work, only 9xxx drivers provide TFP (texture_from_pixmap)
|
|
functionality.
|
|
|
|
You need in xorg.conf
|
|
|
|
Option "AddARGBGLXVisuals" "True"
|
|
|
|
in 'Section "Screen"' and also the XComposite extension enabled:
|
|
|
|
Section "Extensions"
|
|
Option "Composite" "Enable"
|
|
EndSection
|
|
|
|
|
|
ATI:
|
|
--------
|
|
|
|
The radeon driver should work for R200 chips, it's worse with R300 chips.
|
|
TODO - fglrx - no idea
|
|
|
|
You need in xorg.conf the XComposite extension enabled:
|
|
|
|
Section "Extensions"
|
|
Option "Composite" "Enable"
|
|
EndSection
|
|
|
|
Also using
|
|
|
|
Option "XaaNoOffscreenPixmaps" "true"
|
|
|
|
in 'Section "Screen"' may improve performance for non-TFP (texture_from_pixmap) modes.
|
|
|
|
For the TFP mode AIGLX needs to work. With AIGLX direct rendering should be be disabled
|
|
(see GLDirect below, with X.org older than 7.2 "export LIBGL_ALWAYS_INDIRECT=1" before
|
|
running kwin may be necessary).
|
|
|
|
|
|
Intel:
|
|
-------
|
|
|
|
TODO - no idea. Possibly similar to ATI.
|
|
|
|
|
|
Configuration options:
|
|
----------------------
|
|
|
|
All general configuration option are in group [Translucency] in kwinrc config file:
|
|
|
|
UseTranslucency=<true|false> - enables/disables compositing support
|
|
GLMode=<TFP|SHM|Fallback> - selects texture creating mode
|
|
RefreshRate=<number> - manually specified refresh rate, should be usually automatically detected
|
|
GLAlwaysRebind=<true|false> - may increase speed with some graphics cards
|
|
GLDirect=<true|false> - enables/disables direct rendering
|
|
GLVSync=<true|false> - enables/disables synchronizing with monitor refresh
|
|
|
|
ShowFPSEffect:
|
|
Options are in group [EffectShowFps] in kwinrc config file:
|
|
Alpha=<number 0.0-1.0> - transparency
|
|
X=<number> - X position, negative is from the right edge, -10000 is exactly right edge
|
|
Y=<number> = Y position, the same like X
|
|
|
|
|
|
Effects:
|
|
--------
|
|
|
|
Effects can be currently enabled/disabled only by modifying effects.cpp source file.
