Re: [PD] Turning on/off an installation
HI all ! Nice thread, no doubt. Will read more later... My concern is about creating a simple way so that anyone that is allowed can easily turn on and off and installation. I mean the whole power, not just the sound or video. Of course, I am more into lasting installations too. ;) For a window manager. I benchmarked a bit, and I found that Icewm is faster than Fluxbox and some other similar (blackbox and madwm, I think). It looks like Win98, though...

What type of video files and at what size? How many clips are playing on one machine at the same time? What is the display resolution? The Intel graphics have some problems above usual desktop sizes and shader performance is really horrible too. Try increasing the gemwin frame rate above 30 or to run it at the refresh rate fo the display (60 for LCD).

running or use the schedule to sleep and startup as required,

Re: [PD] Turning on/off an installation
Hi Alexandre, I've always kept my machines on, and my projectors/screens are the things that get switched on and off. Most of my installations deal with previous days anyhow... I've has installations running for many weeks on constantly. The current one uses [shell] to turn dpms on and off on the monitor to make it suspend, and turns off the camera movement according to a schedule in the patch. Are you worried about wearing out the HW? (mechanical parts?) B. Bogart Alexandre Quessy wrote: Hi all, I was wondering if someone has an idea on how one could create a switch to turn on and off an installation. I was thinking about either a push button to turn it off, or a web interface. Maybe one of those two things could make Pd (or PHP) write to a file that would be parsed by a cron job every minute. That cron job should be owned by root in order to be able to halt the computer. Then, to turn it on, I guess one could set the bios to turn on the computer automagically when the power gets down and then up again... Or one could use the computer power button (but in this case, it is an laptop that I want to hide deeply...)

[PD] Turning on/off an installation
Hi all, I was wondering if someone has an idea on how one could create a switch to turn on and off an installation. I was thinking about either a push button to turn it off, or a web interface. Maybe one of those two things could make Pd (or PHP) write to a file that would be parsed by a cron job every minute. That cron job should be owned by root in order to be able to halt the computer. Then, to turn it on, I guess one could set the bios to turn on the computer automagically when the power gets down and then up again... Or one could use the computer power button (but in this case, it is an laptop that I want to hide deeply...) The whole idea behind this is to avoid to suddenly turn off the computer, which would probably corrupt the file system at some point. Of course I use GNU/Linux : probably Ubuntu Server or Debian.

You can use the powerbutton actually to savely switch off the computer, if it has ACPI enabled. On Debian/Ubuntu you should check what's in /etc/acpi/events/powerbtn This script normally just calls /etc/acpi/powerbtn.sh which as default calls /sbin/shutdown -h now but you could also put other stuff there. In the BIOS of your machine you need to set up that the powerbutton doesn't immediatly switch off the machine, but only creates that button event. I think, most modern machines are set up like that anyways. Just try it! After synching and closing everything of course. ;) Ciao -- Frank Barknecht _ __footils.org_ __goto10.org__ ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Any suggestion ? hi alex, I lately setup a video installation using a Debian Lenny box on a mini-PC, that's hidden in the ceiling because of noise and visual distrubance. Of course the ACPI button is very difficult to reach, Bios has been setup to restart after a power failure. The power cord is over 10m long and connected to a switchable power adaptor. Shell access is granted from the artist's laptop running windoze thanks to Putty. Pd is started/stopped from the command line. The box is shutdown thanks to the magical sudo halt command line. I used to connect that machine to an UPC, but never had enough time to have it commanded over serial port which a very good solution to both protect your machine from data loss and have it start/stop at will. ++ O. signature.asc Description: Ceci est une partie de message numériquement signée ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

enabling power on by lan (in the bios) should allow remote control (along with shutting down via ssh or telnet i expect) all the best adam ___ All New Yahoo! Mail Tired of unwanted email come-ons?
