I was able to workaround this by running:

xbindkeys --multikey -n
and then moving my lid a few times. This output:

"NoCommand"
    m:0x40 + c:53
    Mod4 + x
"NoCommand"
    m:0x40 + c:133
    Mod4 + Super_L

So I put that into a ~/.xbindkeysrc and I ran xbindkeys daemon. Now my 
"x" key works but I can move the laptop around and see the tools button 
light turn on but no "x" is typed. By the way, I found to Dell forum 
postings about this (on a different laptop) that also mentioned the "x" 
coming from the Windows multimedia key and the fix was for both to take 
the hardware apart and put something to insulate the key from metal and 
some connection.  I will need to take that hardware apart. But for now 
at least I have an X11 solution!
