Hey ppl, I'v been tryin to get irexec to run as root at startup so that I can have the remote restart X when the frontend freezes or messes up.

I'v tried putting it in the bootmisc script right under lircd but it never loads there. i'v tried the apps script in .fluxbox under the mythtv user but that just runs it as mythtv who cant restart X then I put lircd in the sshd startup script sence it loads earlier then most of the other scripts and irexec in various scripts including gdm, mythbackend, samba, and mysql but it never loads! I'v been using the "-d" switch so it runs as a demon.

Can anyone help me out please

hello? mcfly? irxevent let's break this down ir(infared)x(xwindows)event(went something happens) so irxevent is not going to run outside of xwindows, and it's very doubtfull that you'll be able to get it to restart X though you may be able to get it to run a script which uses sudo to restart gdm or something.

He said irexec not irxevent. Not sure if the same problem would apply. Does it work if you run irexec as root from a console?

Yeah greg. IRExec works perfectly when I run it as root from the console and I have the lircrc file setup so it restarts xfree86 from the power button of the remote. I just need it to run as root from startup. Have any ideas?

Find out where lircd starts because its a fair bet that the daemon would need to be running and ready to accept connections before irexec was run. In my case, I start lircd in /etc/init.d/bootmisc.sh
Then add a line after lircd is started that delays for a few seconds (to give it time to start up) then starts irexec. For example:

Thanks for the helpful reply Greg but unfortunately it didn't work
Here is what I put at the end of bootmisc.sh:
I tried the last line in the console and it worked but it just wont work at startup...
Maybe it has something to do with the permissions of the irexec file?
Could you try it on your Knoppmyth box? It would be easier for you to help me that way. Thanks!

I'll give it a go if I get a chance. I run my irexec in .fluxbox/apps, but as you say, this means it runs as mythtv user.

OK, when I ran irexec as root I got an error about it not being able to find the .lircrc config file. This may be your problem too.

In my case, the config file is ~mythtv/.lircrc

You can pass the config file on the command line to irexec. Try:

Also on my system, irexec is in /usr/bin/irexec not /usr/local/bin/irexec so you might want to check that (although I have had to build lirc from source).

When I did this in bootmisc.sh it worked fine.

Thanks a LOT greg! That worked for me perfectly except I decided to go with 3 seconds instead.

I got a new problem with this now. I upgraded to R5A22 and now it doesn't work. First I found that irexec is in a diffrent location so I updated the command to this "(sleep 1 ; /usr/bin/irexec -d /home/mythtv/.lircrc) &" I changed the location to the new one and the sleep time to 1sec because lirc starts before this now, right?
So after thoes changes it still wont load up at boot...
However it will start by manually typing irexec -d as usual.
What's with this?
THANKS!

P.S. Remeber this is in bootmisc.sh

Can you redirect the output to a log file (including stderr 2>&1) so that you can see if it is reporting an error.? I think A22 automatically runs irexec as mythtv by calling launch_irx.sh from ~/.fluxbox/apps if your lircrc file uses it. Could this be causing you problems?

ok I tried "(sleep 1 ; /usr/bin/irexec -d /home/mythtv/.lircrc) & > /myth/irexecout" but that just made a blank file. Mayb it doesn't give output?
What's "stderr 2>&1"? I'm not a pro programmer like u guys.
I looked in /home/mythtv/.fluxbox/apps and there is no line to run the launch_irx.sh script but that would run it as the mythtv user.

2>&1 means that data written to standard error (which most error messages probably are) will be written to standard output. I can never remember were on the command line it should go.

Try something like this:

That looks more correct. The way to remember this is that redirection on the command line is processed left to right in the order that you would read it, and something like 2>&1 sends 2 to the same place that 1 is currently going. If you redirect 1 again later, 2 gets left behind.

I tried "(sleep 1 ; /usr/bin/irexec -d /home/mythtv/.lircrc > /myth/irexecout 2>&1 ) &" but theres still no output. Then I thought it might be because of the daemon mode "-d" so i took that out and still nothing... So I figure that irexec just doesnt give any verbose output at all, it doesnt even have a verbose command switch.
Then I messed wtih the command a bit and tried "/usr/bin/irexec -d /home/mythtv/.lircrc" but that STILL didn't have any effect.
Now i'm wondering if lirc is actually starting before bootmisc.sh or not.
