I’ve been a happy CentOS user ever since version 6.3. CentOS and Debian are two linux flavours that I have been playing around with since past few weeks and found both to be amazingly stable and smooth.
Ever since CentOS 7 came out, I was itching to try it. I’m a regular reader of dedoimedo’s linux musings. That guy has been writing awesome articles after articles on Linux apart from other topics. His article on CentOS 6 made me try it out so I was waiting for his take on CentOS 7. His first article seemed that he had tried it a bit too early so I thought it’s better to wait and watch. His second article – CentOS 7 – The perfect desktop guide is what got me going.
There are quite a few useful repos mentioned in the guide. The real cherry on the cake though, is nux’s CentOS 7 Repo. It’s got a lot of useful stuff. Really useful stuff that matters.
He is the creator of Stella Linux which is simply the most amazing Linux Distro. It’s a remix of CentOS (That’s how nux prefers to call it). It’s awesome.
Ok. Let’s start tweaking CentOS 7. One note before we start. I had selected the “Development and Creative Workstation” option from the Software Selection Section so that it would automatically install a lot of packages during installation itself. You might need to install other packages if you have selected any other option.
First off, as given in the guide above, run the update command:
Note – You’ll have to run all the commands as root.
Reboot and check if all looks fine.
Install the epel, elrepo and the nux repository. I had the epel repo pre installed so shown below are steps to install the elrepo and nux repositories only.
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
Run the yum update command once again.
Note – Please check for the latest packages before you run the commands. As pointed out by Ruud de Bruin, the Nux Repo link is updated. Thanks Ruud.
Here’s the link – https://li.nux.ro/repos.html
Ensure that you select the CentOS 7 link
The very next thing I did was installed the latest kernel-ml from Nux’s repo. That’s because with the stock kernel I was having issues toggling screen brightness and after some googling around I had found that 3.16.2 fixes that and few other issues (while on Stella Linux 6.5). So off I went installing it.
yum --enablerepo=elrepo-kernel install kernel-ml
That gave me kernel version 3.16.2. So I rebooted once again, selected the kernel version 3.16.2 and all fine and dandy after that. Brightness toggle works perfectly. System boots a little faster as well.
The fonts appeared fuzzy. Well, a good .fonts.conf file should solve that. I had one lying around since my last tryst with Debian. This is an exact copy of what I found on the Debian Forum. It had worked well on Stella Linux 6.5 (Which is a remix of CentOS 6.5). Here’s the content of that file.
<?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> <match target="font"> <edit mode="assign" name="hinting" > <bool>true</bool> </edit> </match> <match target="font" > <edit mode="assign" name="autohint" > <bool>true</bool> </edit> </match> <match target="font"> <edit mode="assign" name="hintstyle" > <const>hintslight</const> </edit> </match> <match target="font"> <edit mode="assign" name="rgba" > <const>rgb</const> </edit> </match> <match target="font"> <edit mode="assign" name="antialias" > <bool>true</bool> </edit> </match> <match target="font"> <edit mode="assign" name="lcdfilter"> <const>lcddefault</const> </edit> </match> </fontconfig>
I copied this to my home folder. Remember, the name of the file has to be .fonts.conf. Notice the “.” at the beginning. It has to be in your home folder. So say, your home folder is at /home/yourname, then you’ll need to ensure that you copy the file in that location.
[pmu@localhost ~]$ pwd /home/pmu [pmu@localhost ~]$ ls -a | grep ".fonts.conf" .fonts.conf [pmu@localhost ~]$
Logged out and logged back in. The application and browser fonts were much better now. But for best effects, we’ll install infinality. It really makes a huge difference. And this is where nux’s repo comes in. He has done all the hard work already. We just need to install the packages like so:
yum --enablerepo=nux-dextop install fontconfig-infinality yum --enablerepo=nux-dextop install cairo yum --enablerepo=nux-dextop install libXft yum --enablerepo=nux-dextop install freetype-infinality
Rebooted once again. And man, I could tell the difference. The fonts were amazingly clear. Way better even than on Windows.
Here’s some screen shots:
The second last screenshot here shows the changes I have done to some default fonts. CentOS 7 looks way snappier to me this way. Like I said earlier, The fonts were amazingly clear. Way better even than on Windows. No kidding.Windows…heck, I needed to install the packages so that I could mount my USB Disks that are NTFS partitioned.
yum install ntfs*
Okie….Did that, and was able to access my windows partitions without any problems.
Now we’ll install sensors package so that I’d know how’s the laptop temperature doing:
yum install lm_sensors
And configure it as a root by running the following command and selecting the answers to the interactive questions.
Though I like the default adwaita theme, the icons could be really better. Once again the nux repos come to the rescue.
yum --enablerepo=nux-dextop install faience-icon-theme
Select the theme in the Tweak Tool as shown below:
Now the icons look much much better.
I left out the touchpad settings. Here’s how we go about it.
Hit the “Windows” key, and you’ll get a screen like this.
Now type the word “touchpad” (without quotes)
Click on that option and then change the setting the way you want.
This is how my settings look:
I have enabled the “Two Finger Scroll” and most importantly the “Tap to click” option.
That’s it (for now). We are done. All thanks to dedoimedo and nux, I got a snappy looking CentOS 7 running right now. Infact I wrote this blog on CentOS 7.

Ever since I installed Centos7 i’ve been muttering about the screen appearance and the fact that I can’t get at my Windows HD.
Your tips solved everything in a matter of minutes. Screen fonts DO look better than Windows and my Eclipse editor is finally readable! Great work!
Glad you found it useful. Most of the stuff here is what I found on the net. The real stars are folks like Dedoimedo. Do check out his site. Link is in my article.
