I am trying to write an app that will perform some actions when a network interface is unplugged. Is there a way to get the OS to signal me when a network interface is unplugged. I have looked at DBus but can't figure it out.

I know how to deal with a mouse click event like so:
Code:
But was happens when I am dealing with mouse dragging? Will my implementation of mouseDragged() get called for every pixel moved? So I just getX() and getY() like with a mouse click?
Also, in order to know when mouse dragging stops and starts, do I also have to put code in mousePressed and mouseReleased?
How to do so? For starters, I'm not sure there is such an event. Maybe it has something to do with the OS moving through certain run-levels

Pianobar has the ability to run a script based on events, I'd like to take advantage of and use perl toparse the artist,song,album and update the corresponding fields. Then later retrieve them and display them with php/html. I am by no means proficient with perl. I started to use bash, but it looks like perl will be much more efficient and and less time consuming.
Code:

I have Update Notifier enabled in my startup apps and I've checked that update-notifier is actually running, and I have my updates set to check for updates daily and only notify about available updates. However, I never get any notifications despite having updates available. I'm using Unity on 11.04 and I've enabled "all" icons on my top panel.

View 10 Replies View RelatedA client has a desktop program that uploads images and data to a certain folder where i have a script that imports it to a DB, this all works. But i cant just set it to a hourly cron or have the client run a script after they have uploaded via FTP (the client is not techy).
So I need a way to detect when they have finished uploading all the data via ftp, which i just cant see a way of doing....it would have to be a linux command where it notifies a php script when the client has logged out of ftp, then disables shell access temporarily imports the data they have uploaded then reactivates shell access...but i have no idea what linux commands i would have to look into to get this working.
When I getch() a key event (UP arrow key), the getch() function return a string of characters that I cannot compare with curses.KEY_UP constant. Here is the code I use :
while True:
w = gb.scrn.getch()
c = chr(w)
otp = 'touche:'+str(w)+' '+str(c)+"
[Code]...
It seems like getch() return three distincts bytes while I would retrieve it with a single ord() instruction in python like describes in curses/python documentation.
I've noticed g-p-m refreshes information extremely delayed. Sometimes it takes many many minutes before it notifies me that I'm running on battery. how I can change this refresh rate? I've drained the batteries once recently believing the icon that said 89% less than a minute before the batteries were completely discharged (my battery lasts for about 15-20 minutes).

View 1 Replies View RelatedWith /usr/bin/canberra-gtk-play set to --id='desktop-login' in the startup Applications dialog one expects a sound to play at login. This is not the case with fedora 12. I set the variable to --file=/home/me/sounds/myloginsound and I got sound.
I'm curious as to why the event id failed. I suspect that id was not linked/associated with any sound before fedora 12 was released. How does one troubleshoot sound event ids and their associated sounds in f12.
I'd like to get audio when I log out as well. I recall seeing a dialog box with events and associated sounds in f11 (or was it f10?) .... I don't see it in f12
1. Does anyone know which package adds that functionality?
2. In the absence of a GUI approach, how can this be achieved (with the terminal)?
I have a program running on my server which I want to restart in the event that it ever crashes. Someone suggested "Watchdog" to me, but it appears to me that watchdog restarts the whole system, not the program. I couldn't find much documentation for it. Another suggestion I was given was crontab, except that I don't want to relaunch the program every 60 seconds, as it doesn't run on screen or anything, it forks itself into the background after launching it. Perhaps a bash script that would check to see if the program were running or not, and if it weren't, relaunch it? Not sure how to do that, I've never written bash. In any case, I just want to keep this program running full time.
View 6 Replies View RelatedEver since 9.04 or thereabouts, I have noticed that it's impossible to change individual system event sounds in System -> Preferences -> Sounds. It only gives me a few lame choices of "themes". While it used to be possible to define my own sounds for startup, shutdown, new e-mail, etc, I can't find ANY dialog to facilitate this in newer versions of Ubuntu.
A question: HOW do I do this without having to hack apart my stock system sounds? There should be a way, but google and forum searching turns up nothing.
A comment: Ubuntu continuing to "nerf" their dialogs like this is infuriating, especially when the underlying system works so well. I actually don't know if Ubuntu or Gnome is responsible, but either way taking away rock-bottom basic functionality like this only hurts the OS and Linux's cause.
I was turning off my pc and my brother pulled out his sd card while the pc was shutting down. Now when I try to boot up I can't boot into my ubuntu partook it just hangs and then comes up with inittramfs. I can boot into my windows partition just fine. I also tried rebooting with the sd card in the slot but same thing. I managed to load up a live disc but have no idea what to do next if I want to save my old partition (if it can be saved) otherwise as a last resort ill have to overwrite the partition.

If the ethernet connection goes down it will connect to wlan. I have found 2 ways of checking ethernet connection, via proc/net/dev and via ifconfig eth0. But if possible I want to avoid polling. So is there any event that is triggered when the table gets disconnect or at least the connection goes down and up?

View 2 Replies View RelatedI have a Logitech Media Play mouse with many buttons. I'm using xbindkeys to create some shortcuts to programs e.g. firefox, gnome-terminal--these work wonderful. What I cannot figure out is how to get the buttons to work for the media player(Ubuntu>System>Keyboard Shortcuts>Sound). I set shortcuts using my win key and letters, hoping to use xbindkeys to send out a keystroke. I have tried to use xmacro but to no avail. xdotool was not helpful, I think it may be outdated(desktop/workspace functions did not work).
My preferred option would be to get mouse events to keystrokes working with xbindkeys and program x(x being whatever works); however, just getting my media buttons to interact with the media play is my ultimate goal.
I know in windows xp there is a registry key and an entry in the Plug and Play log file as well as maybe an event id, that is produced when a device (say usb) is plugged in. My question is, besides /var/log/ (messages?) Is there any other location that that information is stored in?

I am installing canberra for event sound and input feed back sound. I installed freedesktop sound theme and moblin. All sound files are there but only trash empty event trigger sound.
Other events like: login, dialog error , etc etc no sound...
For login I created login.ogg link to destop-login.ogg but canberra-gtk-play claim unknown event id?
I like to have startup sound at xfce login and other event...
I recently gave XFCE a try, after using Openbox for a long time and I really like it, so that I think I will switch totally to XFCE. All is working fine, except one thing: I really would like to have event sounds.
So I launched the Appearance-Module and checked under the Settings-tab both Enable event sounds and Enable input feedback sounds. Following the tooltip for the event sounds I also installed libcanberra, but I get absolutely no event sound.
[Code]...
I thought, maybe there is a lack of a sound theme, so I also installed freedesktop-sound-theme, but that didn't help. I did already searched with Google and in this forum, but have found nothing that would help me. I would be very happy if anyone can give me an advice what to check or has a link to a tutorial for this sounds.
I use network-manager-pptp to connect to my VPN server. However, occasionally my VPN drops out (although my Internet stays up). I was just wondering how I could make the VPN drop-out trigger a bash script, for example playing a sound to alert me that the VPN has dropped?

I've tried two copies of a: Microsoft Natural ergonomic Keyboard 4000 v1.0 Both fail. The result is my screen fills up with whatever key was missed. Re-pressing the key does no good. I have to unplug the keyboard and then plug it back in. So, I'm interested to know if this is a general problem or just my system. Meanwhile, I'm turning down the key repetition rate so it doesn't immediately fill my screen when it happens.....
