observed "expected keysym, got XF86TouchpadOn" and "expected keysym, got XF86TouchpadOff" with Xvfb on Centos6

[Jun Chen <jun.chen@xxxxxxxxxxxxxxxxxx>]

Hi,

I am hoping experts in this mailing list could help me with this:

We have an application which used 
xorg-x11-server-Xvfb-1.1.1-48.76.el5_7.5 before and worked fine.  After 
upgrading the host to Centos6, along came 
xorg-x11-server-Xvfb-1.10.4-6.el6_2.1.x86_64,  we started seeing

expected keysym, got XF86TouchpadOn: line 120 of inet
expected keysym, got XF86TouchpadOff: line 121 of inet

as stderr.  What does it mean and how to suppress it?  It seems 
harmless, but annoying.

Thanks very much in advance,

Jun
