Using the Composite extension with Xorg
pacman -S xorg - obviously you need this, version 6.8.0 or higher.
pacman -S xcompmgr - Composite Window-effects manager for X.org
pacman -S transset - Translucency settings tool for X.org
Edit your xorg.conf
Add an "Extensions" section to your xorg.conf, and enable the Composite and RENDER extensions:
(Note: RENDER is automatically enabled if you enable RenderAccel for your Nvidia card -- see below)
Section "Extensions" Option "Composite" "Enable" Option "RENDER" "Enable" EndSection
If your graphics card is an Nvidia card, enable
RenderAccel in the
Device section for your graphics card:
Option "RenderAccel" "true"
xapps comes with a (proof-of-concept) composition manager named
xcompmgr. To run it:
To have it run every time X starts, add this to your
xcompmgr -c &
-c you can experiment with the other switches for different types of effects or no effects at all. For example,
-cf will include a fade effect.
xcompmgr --help for a list of options.
Setting transparency on windows
Transset is a program that will let you manually set the transparency of windows.
.. Where the optional
n is a number from 0 to 1. 0
fully transparent, 1 no transparency.
Running transset presents you with a new cursor, and you click the window whose transparency value you want to change.
- Fluxbox windows won't raise
This is fixed in fluxbox CVS after 0.9.10. See  for more info.
A workaround in 0.9.10 is to set the layer of the Slit to "Desktop" (flux menu -> Configure -> Slit -> Layer -> Desktop).
- Mozilla Firefox crashes when entering a Flash site
You can fix it by either createing a executable file in /etc/profile.d called flash.sh including this line:
Or adding the line into line 184 of /opt/mozilla/bin/firefox.
You still have your composite, you still have your flash. Works perfectly. (Thanks punkrockguy318)
- XWindows Freezes up completely, Keyboard is unresponsive, but mouse still works
If this happens, you probably need to reboot your computer using the button on your computer tower. This appears to be a bug with the Composite extension and Nvidia drivers. Simply remove all the changes from your xorg.conf (ie. Composite, RENDER, RenderAccel, and AllowGLXWithComposite). You will be unable to use the Composite Extension until it becomes more stable.
Some have found removing the RenderAccel setting alone has prevented lockups.
