Nvidia config tool config order of screens doesn t work

Hallo,
after installing 2 Nvidia Gforce 650er cards (2 cards with 2 displays) and the driver from nvidia.com my 4 displays are active and everything is fine.
My question:
the option to configure the displays using the mouse to move the screens in the right order doesn t work like under windows with simple moving. Sometimes it is possible to change the order but sometimes it isn t possible to move a screen between 2 others.
Any hints how to solve this?

how to use 2 Nvidia Cards in one system

Hallo,

is there a way to use 2 different Nvidia Graphiccards in one system?
The first one is working fine with 3 displays but I want to use 2 more
displays with the second card.
Do I need two card of the same series (4 or 7) or is there a way to
mix different series?

Thanks for hints.

elasticsearch connection refused

Hallo,
is anyone here using elasticsearch on centos?
I tried several configs to configure external access but nothing is working.
My tests:
telnet localhost or 127.0.0.1 9200 works local on the machine
telnet 192.168.242.4 9200 connection refused local on the machine. So
it is clear that access from other systems can not work.
Is there perhaps something special to consider when using centos 7?

Thanks for hints.

I try to configure my dhcp-client to send the hostname to a microsoft

A debian system works fine so it seems that the microsoft-side isn t

Thansk for hints.
