prolly dumb questions?

[Bob Hemus]

Folks, when I turn on and boot into any distro and the program loads on
the screen, how do I get it to slow down or even stop and restart so's
I can see what's wrong?  Same thing when I log off.  Also, when I
shutdown with the GUI, right click -> log out "bob" on my SuSE 10.1 it
is SLOW.   When I go to a su - terminal and <shutdown-h now> it goes
down quickly.  This doesn't cause any harm, I hope?

Next ones;  When I was goofing around with the Xserver I some how
screwed something up so I get these two messages on my first open
window. 

<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"
EndSection> and 

<The Composite Manager crashed twice within a minute and is therefore
disabled for this session.>
This, also, is on my SuSE 10.1.  Any suggestions where I need to go
(please be careful, I'm tender) to fix it?
