Summary
LIRC is a package that allows you to decode and send infra-red signals of many (but not all) commonly used remote controls.
Install: Fedora Core 7 (Yum)
For Fedora Core 7 I used the atrpms repository. They have already built all the necessary binaries we will need for the installation. You can checkout their install page or follow the condensed instructions.
-or-
Install the GPG-Key:
rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms
Copy the text below into the following file:
/etc/yum.repos.d/atrpms.repo
[atrpms] name=Fedora Core $releasever - $basearch - ATrpms baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms gpgcheck=1 enabled=1
Install the needed packages with yum:
yum install lirc-lib-devel lirc-lib lirc lirc-kmdl-`uname -r` lirc-devices
Hauppauge WinTV-PVR-150, WinTV-PVR-350 Cards
Load the module for Hauppuage 150 and 350 PVR cards with the commands below and then restart lircd:
depmod -a modprobe lirc_i2c /etc/init.d/lircd restart
Enable Lircd on Startup
chkconfig lircd on
Note: See Could not get file information for /dev/lirc (Lirc Reboot Errors) for a fix when Lirc doesn't work after a reboot.
Lircd Files
Lircd files map infrared hex singnals to key names.
Add remotes to the lircd configuration file:
/etc/lircd.conf
Note: Lircd should be restarted after any modifications to this file.
/etc/init.d/lircd restart
Hauppauge WinTV-PVR-150, WinTV-PVR-350 Cards
You can browse the remotes folder that is included in the lirc documentation for your remote control's configuration file.
cp /usr/share/doc/lirc-*/remotes/hauppauge/lircd.conf.hauppauge /etc/lircd.conf

Lircrc Files
Add commands to the default configuration file:
/etc/lircrc
Additionally you can use place the configuration file in your home directory:
Note: If this file is present it will override the file in /etc/lircrc
~/.lircrc
Note: Lircd should be restarted after any modifications to this file.
/etc/init.d/lircd restart

Irexec Files
Irexec in conjunction with Lirc will run programs with one button press on your remote control.
Note: You must create the file /etc/irexec.conf file in order for Lircd to start irexec.
vi /etc/irexec.conf
#-------------------------------------------------- # File: /etc/irexec.conf (This works with the '''Hauppage 150 Silver & Black Remote''') #-------------------------------------------------- begin button = Power prog = irexec config = xset dpms force standby end begin button = Red prog = irexec config = vlc /storage/torrents/csi* end begin button = Green prog = irexec config = vlc /storage/torrents/prison* end begin button = Yellow prog = irexec config = vlc /storage/torrents/family* end begin button = Blue prog = irexec config = mplayer /dev/video0 & end
Force Display Into Standby Mode
If you have a display that supports Energy Star (DPMS) features you can use the following command in your irexec file to force your display into standby mode. This makes it so you don't have to get up to turn of your monitor after your late night move. :P
Test this command in any terminal window and it should turn your screen black.:
Note: Simply move your mouse or strike any key to get your display back.
xset dpms force standby
If the above command worked correctly set it to a specific key on your remote control. I choose the green power button, but you can adapt the configuration below to fit your situation:
begin button = Power prog = irexec config = xset dpms force standby end
FAQ
Could not get file information for /dev/lirc (Lirc Reboot Errors)
[root@server.com rc.d]# tail /var/log/messages | grep lirc Nov 19 20:17:50 core lircd-0.8.3-CVS[2268]: accepted new client on /dev/lircd Nov 19 20:17:50 core lircd-0.8.3-CVS[2268]: could not get file information for /dev/lirc Nov 19 20:17:50 core lircd-0.8.3-CVS[2268]: default_init(): No such file or directory Nov 19 20:17:50 core lircd-0.8.3-CVS[2268]: caught signal
Some systems will fail to auto load the lirc module. There are various ways to fix this problem but I found editing the /etc/init.d/lircd startup script to be the easiest.
Edit: First 6 lines in the Start() section.
