Install MythTV Frontend v27.5 on Centos v7.1 (scrpms)

Old notes from a previous install from 2016.

These are notes on installing MythTV frontend on a low end old AMD frontend, with a nVidia graphics card, a Microsoft remote and NFS for video. The MythTV backend and MySQL/MariaDB database server run on independent virtual machines (not covered by these notes).

This install was done while ATrpms was down (with the possibility that it may not return).  I had a local copy of the ATrpms mirror I used for dependencies.



  1. Install base machine (CentOS 7)
  2. Install nVidia graphics driver
  3. Install MythTV frontend
  4. Add a mythtv user that auto-logins in and runs mythtv frontend
  5. Disable screen savers
  6. Add an NFS share with videos
  7. Configure sound via HDMI


Install the base operating system with gnome and setup network connectivity.

Set the hostname in '/etc/hostname':

Disable network manager on the main network interface:





Lock down ssh.


Setup the following RPM repositories:

  1. scrpms (mythtv)
  2. atrpms (dead)
  3. epel (dependency)
  4. elrepo (nVidia driver)



# rpm -Uvh
# rpm -Uvh
# yum install

Create a local repo file for scrpms in '/etc/yum.repos.d/scrpms.repo':

name=A CentOS Build of MythTV v0.27 by Stephen Collier

Note: At the time of writing ATRpms was down, so I used my local (private) mirror:

# rpm -Uvh



yum install kmod-nvidia
yum remove xorg
# yum install mythtv-frontend

Disable nouvea driver


Add a blacklist command to the linux command line in '/etc/default/grub':

GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet rdblacklist=nouveau"

And regenerate the grub configuration:

# grub2-mkconfig -o /boot/grub2/grub.cfg

Frontend User

Add a user for the front-end.

# adduser mythtv
# passwd mythtv

Automatic lauch

Auto login

Edit '/etc/gdm/custom.conf' to configure the mythtv user to automatically log in:




Auto start

Create a startup script that will lauch (and re-lauch if it crashes) the mythfrontend program as '/usr/local/bin/start-mythtvfrontend'. Tweak this up as required to display screen savers etc.  Due to bug 12034 I have to display the http proxy settings otherwise recordings won't play.


# see
export http_proxy=
export https_proxy=
export ftp_proxy=
export no_proxy=

xset -dpms s off
xsetroot -solid black

while ( ! $( mythfrontend > /tmp/mythfrontend.log 2>&1 ) ) ; do
  echo "Restart in a few seconds"
  sleep 5s

Create a gnome autostart desktop file '~mythtv/.config/autostart/mythtv-frontend.desktop':

[Desktop Entry]
Name=MythTV Frontend


Mount the collection of video using NFS. This is made available over a storage VLAN. Add a network sub-interface  configuration file '/etc/sysconfig/network-scripts/ifcfg-enp3s0.200':


# IPv4

# IPv6

Create a directory for the NFS mount

# mkdir /mnt/mp4

Add an entry to '/etc/fstab':          /mnt/mp4                nfs4    ro               0 0

Verify that the NFS mount is operational (mount -a)

Remote control

Add Linux device input support

# yum install v4l-utils lirc lirc-remotes iguanaIR libcec
Note: '

iguanaIR' is an unexpressed library dependency.

/bin/cp /usr/share/lirc-remotes/devinput/lircd.conf.devinput /etc/lirc/lircd.conf
systemctl enable lircd
systemctl start lircd

Disable unused services


# for S in ModemManager cups firewalld bluetooth ; do systemctl stop $S ; systemctl stop $S ; done



yum install
