Error message with KDEinit

I am using OpenSuse 13,1 and KDE
When I start or restart my PC is getting the message below.

KDEInit could not launch ‘xhost’:

Could not find ‘xhost’ executable.

This is happening after installing a 4G modem Huawei E3276

I close this warning, and the system runs some problems:
1- Much slow to open web pages, via wire.
2- The network drops when plug the modem
3- the option “defaults” used in fstab is changed, and now I need use “user” and “users” instead “defalts”

What can I do to fix it?

Install “xhost”?

I do not understand.
You’re telling me install xhost?

Please, it is much better to have one problem per thread. Each in the best fitting (sub)forum and each with a telling title. As you do it now, the problems you added in the end will not be seen by many.

Ok. I will do this in the future.

I try instal “xhost”, but the error message keeps popping up

What happens when you type “xhost” into a terminal window?

Sorry.
I tried to install “xhost” with YaST, but the installation did not finish and I did not notice this failure.
I did the installation using the apper and this time successfully.
After restarting the error message is not showing up more.

Thank for your help.
