[Pkg-acpi-devel] Bug#565908: acpid: causes Xorg to hang because of "too many connections"

[Ted Felix]

  If you don't mind grabbing the code and building it, you can go into 
the file connection_list.c and change this line:

#define MAX_CONNECTIONS 10

  To this:

#define MAX_CONNECTIONS 20

  That will get rid of the "Too many connections." message in the log.  
Whether it will solve your problem, I'm not sure.  I will include this 
change in my next monthly release on 2/15.  Let me know if you need more 
info.

Ted.
