Re: error Composite extension not found

Good morning all,

I am new to linux so please pardon if this a dumb question or I have
failed to look for the solution in some obvious place.

I have installed debian testing (etch) and after some effort was able
to get kdm and KDE running on start-up. I did some configurations,
details of which I do not remember, but since then after start up I
get the two error pop-ups.

The first says Composite Manager crashed twice in one minute and has
been disabled for this session. The second pop-up says:
Composite extension not found.
You must use XOrg >= 6.8 for translucency and shadows to work.
Additionally, you need to add a new section to your X config file:
Section "Extensions"
Option "Composite" "Enable"

My questions are as follows:

What is composite manager?

An addition to the X-window system which allows it to use the graphics
hardware more efficiently when doing things like displaying translucent
windows. Otherwise these things would be much slower and need a lot of
CPU time.

How do I find out which version of XOrg I am using?

Run "X -version" from a terminal.

Can I upgrade to XOrg >= 6.8> How?

If you have an up-to-date Etch you have XOrg 6.8 already; XOrg 6.9 is
currently only in Sid. (KDE does not check for your XOrg version before
it displays the error message.)

How do i turn off Composite Manager.

Go to "K-Menu > Control Center > Desktop > Window Behavior >
Translucency" and uncheck the "Use translucency/shadows" box. If you are
new to Linux it is probably better to leave this feature alone for now.
