Hi, good folks!

I apologize in advance for cluttering up the "Expert" list with stuff from a Newbie, 
but this is one I haven't a clue how to trace and solve.

A couple of days ago, I was faced with what appeared to be a locked-up "X" ("kdm" from 
all evidence -- it's whatever Mandrake 7.1 installed for me), so I did the "X" 
3-finger salute of <ctrl><alt><backspace> and after 15 seconds (or so), I got to log 
back in.  Ever since then (through several shutdowns, also, btw!), every 5 minutes, I 
get a string of the following in the syslog (I follow the log with "tail" to watch my 
firewall in action!):

Oct 23 13:37:16 localhost init: Id "x" respawning too fast: disabled for 5 minutes


At this moment, doing 

  ps -ef | grep [k]dm

returns the following (spacing may not be accurate):

  root      735    1   0 12:04 ?        00:00:00 kdm lang-sh-end
  root     1798  735   0 12:10 ?        00:00:00 [kdm]

I've tried killing various combinations of the pids mentioned (in this example, "735" 
and "1798");  this just gives me the opportunity to log in again and restart all my 
background stuff up again.

I've tried putting a "SIGSTOP" on the what I deduce is the "child" (because of the 
parent pid 
not being "1"), but it just resumes itself (or something else resumes it) and 5 
minutes later I get another rash of the "Can't lock pid file" activity.

Whew.  Is there someone reading this who 1) knows what's going on;  and 2) can tell me 
how to make it stop happening?  I know I can stop it by reinstalling the OS, but this 
isn't the Redmond OS, one isn't supposed to have to reinstall for silliness like this!

Apologies again, and TIA!

I hope you and yours are prospering!
