x only works for root

[tripolar <tripolar@comcast.net>]

I have had problems with permissions in /usr/X11R6
I set them #chmod 755 -R /usr/X11R6/
does that look right?
that has worked in the past.
I was told to remove files in /tmp  relating to dcop or orbit ( sorry I 
forgot and I am not on that machine because x only works for root and I 
have yet to figure out mutt ;-) )
I have messed with permissions in /tmp
what user & group should /tmp be?
at this time the only  twm for regular users though I cant open any apps 
like kmail or evolution or  mozilla
$kmail
trying to creat local folder:Permission denied
failed to create /tmp/ksocket-tripolar/
_KDE_IceTransSocketCreateListener: failed to bind listener
....
DCOPServer self test failed
kdeinit: DCOPServer could not be started
.....
Can't setup DCOP communication

Any suggestions? again I messed up /tmp user & group & permissions. need 
to know the correct user, group and permissions of /tmp
also anything relationg to dcop & permissions to get reg users to log 
into x from gdm
Thanks
