/etc/init.d/gdm restart will do it, it's ugly and restarts more than just the frontend, but will accomplish the goal probably more easily than anything else. |

Code: export DISPLAY=192.168.1.100:0
nohup mythfrontend & use your own IP address in the DISPLAY command |

your own IP of the local machine or the myth machine? I am intersted in this as well. Does that move the display over to the remote machine or does it just permit you to be able to start frontend via ssh? Thanks so much!! |

sorry for the quick response, I was in a hurry. you need to ssh or telnet into the frontend box Code: ssh <ip address of frontend box> once you have a terminal window on the frontend you can run any program you wish. It executes on te frontend. The trick is telling any X programs where to display the GUI. X uses a variable DISPLAY to determine this. when you log into the console on the frontend it gets set automatically. Since you connected remotely, you need to set DISPLAY yourself. Code: DISPLAY=<ip of frontend>:0 export DISPLAY now when you run mythfrontend, the gui will be displayed on the tv. Couple ohter comments: add an ampersand & to the end of the command to cause it to run in the background. this wiil return you to the command prompt to do more stuff or to logout. add 'nohup' to the beginning of the command line. When you eventually logout of the terminal window, the shell will send a signal to all of the background process that the shell is exiting. the signal, HANGUP, causes the background processes to exit as well. so exiting the terminal will kill the mythfrontend process. by prepending nohup to the command line, the child process (mythfrontend) will ignore the hangup command. If this something you plan to do offen, I would create a script to do it (use your own frontend box ip address) Code: MYTHFRONTEND_IP=192.168.1.50
DISPLAY=${MYTHFRONTEND_IP}:0 export DISPLAY nohup mythfrontend & This same script can be used by LIRC to start the frontend with a remote control button. |

To start the frontend using the remote control, wouldn't you just need the last line: nohup mythfrontend & because you're issuing the command on the myth machine and not remotely through ssh? |

FWIW, I've been doing it this way: cat /usr/local/bin/rfe.sh #!/bin/sh #rfe - reboot front end #Purpose: restart the front-end when it's crashed. #by Chris Thornton #11/27/2005 /etc/init.d/gdm stop echo Sleeping 4 secs... sleep 4 /etc/init.d/gdm start echo Done! I've got it with the setuid bit set, and I just call it. I don't have LIRC working yet, so I just use my RF keyboard to run from one of the other consoles. It's mainly useful in situations where the whole X envronment is messed up, and I want to "reboot X", as opposed to just starting the front end. |

Can someone tell me how to do this as user mythtv? Seems like running the above script needs to be done by root. Maybe I'm missing something simple. Many thanks! |

Dinki, my script will run for non-root users. |

Krusher, doesn't work for me. export DISPLAY=192.168.0.100:0 nohup mythfrontend & Produces: [1] 844 (~) mythtv@mythtv$ nohup: appending output to `nohup.out' [I hit enter after a few seconds waiting for the frontend to start and: [1]+ Exit 1 nohup mythfrontend |

there seems to be something wrong with the ip you're using: a 0 (zero) can not be right.. use ifconfig to see the ip (prolly 192.168.1.100) |

If you binaryize (lemme see you find that word in the dictionary!) this out you will see it better. Code: 192 168 0 100
11000000.10101000.00000000.01100100 \------------------------/ \-------/ Network address Host Address The host portion of this address should not be all zeros, but there is nothing preventing a full octet of the network address from being all zeros. |

Wow, are we off-topic. The last poster said that the last 8 bits are for the host address. This is only for a Class C address. Thus: Code: Class A: network.host.host.host
Class B: network.network.host.host Class C: network.network.network.host Just wanted to clarify. Now we return you to your regular broadcast station. |

Quote: mythtv@mythtv$ nohup: appending output to `nohup.out'
Is there any clues in nohup.out? |
