and half with distored colors etc

like that didnt shutdown

i install ati driver, it installed
succesfully and also i changed the
default runlevel in inittab from 3 to 5.

Help me

Does this happen in single user mode, ie console mode?
What happens when you shutdown X (using <ctl-alt-backspace>)?

also try entering the command "poweroff" at the command line. You made need to supply the root password or su or sudo.

U can try from the command line with the user root
"shutdown -h now"
