CentOS 7 dhcp + custom ‘search domain’

I’m running CentOS 7 on my workstation these days, like it a lot.
At work our dhcp setup dns search for the domain containing our windows hosts but the Unix and Linux hosts I work with are in an other domain.
In the network manager gui in gnome3 I can’t seem to figure out where to add this second search domain, so I’ve been adding it manually to resolv.conf after each boot …

Got tired of that so i added:

DOMAIN='myDomain.no'

in /etc/sysconfig/network-scripts/ifcfg-eno1 and did a

systemctl restart network.service

problem solved.

UPDATE 30th october 2015:
This does not work at all at my workstation at my new job.
I’m not using NetworkManager any more, not sure if that’s the reason though.

By setting SEARCH in /etc/sysconfig/network instead things got a lot better:

# /etc/sysconfig/network
SEARCH='example.com sub.example.com'

Enable touchpad in gdm3 login prompt (Fedora 20)

Enabling tapping support in Gnome 3, I still don’t have support for that at the gdm 3 login prompt .

In /etc/X11/xorg.conf.d/50-synaptics.conf I got tapping support for my mousepad at the gdm3 login prompt by adding

Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
EndSection

The file wasn’t there, so I created it.

Fedora (20) enable tuned, save power

I noticed by switching to Fedora, from Ubuntu, my battery time got lower.
I suspect Fedora isn’t as laptop friendly out of the box as Ubuntu is .

Installing Tuned helped a lot on power consumption for my laptop:

$ sudo yum install tuned
$ sudo systemctl enable tuned.service
$ sudo systemctl start tuned.service
$ sudo tuned-adm active

There seem to be a debate whether powersave og balanced is the best option .
