How to play a .wav when I close windows?
location: ubuntuforums.com - date: July 19, 2008
I'm not sure if this is a Gnome thing or a Metacity thing,
but I've found a wav file I would like to have play
when I close a window. I looked under system>>
preferences>>sound and that is not one of the options.
Does anybody know how to get Gnome/Metacity to play
a sound when I close windows?
[SOLVED] How to close a driver file descriptor after killing an application
location: linuxquestions.com - date: November 25, 2011
I hope this is the right place to ask my question.
I wrote a simple character driver in uClinux 2.6.19, which registers an interrupt (falling edge on GPIO line). When I test this driver in simple single threaded application it works well and even in the case when this application is killed (SIGINT, SIGTERM) the driver file descriptor is closed and the irq is freed.
Unfortunately, when I use the driver in a big application with several threads (even detached) it is not closed correctly after killing this application - the irq remains registered and can't be registered again.
I think there can be some zombie processes, but ps shows nothing.
Could please someone give me some advice how to solve this problem?
How to launch an app in terminal, & keep it running after I close terminal?
location: linuxquestions.com - date: October 1, 2005
I like terminal, but sometimes I need to use Nautilus to launch, e.g., PDF viewer.
Then I usually close Nautilus and go on watching PDF.
I want to do the same from within terminal.
Is there a way to launch an app from terminal, and keep it running after I close the terminal?

How can I restrict ports for users to bind to?
location: linuxquestions.com - date: September 2, 2008
I'm setting up a server that will have multiple shell users. They all will be compiling a few applications and running them as their user.
I have mostly figured out how to restrict things like how much memory, disk space, cpu they can use, but I haven't found a common way to lock them down to what ports their apps can run on.
Ideally I'd like to setup their users to have access to bind to ports x - y and that's it. The system I would hope would reserve that range as well, so others or the system itself can't bind to them.
I have found user-port-hack, but that's for the 2.4 kernel and I'm running the 2.6 kernel on my system.
That makes me assume that there is something like that builtin to the latest kernel.....right?
This system is going on a AMD 64 big platform, running centos 5.2 with the latest 2.6 kernel.
How do I change the appearance of the close, maximize, minimize buttons?
location: ubuntuforums.com - date: July 30, 2013
I recently switched from Mint 15 to Ubuntu 12.04 LTS. The transition was easy for the most part and with the help of google and youtube I was able to customize just about everything the way I like it except the title bar buttons. I do not want to change the theme for my whole computer. I like Ambiance. I do want to know: How do I change the close, maximize, and minimize buttons to something more attractive? I would like for them to look like Mac (red close, yellow min, green max- all round) but even Windows is preferrable to the Ubuntu default look. Can I change just the buttons and how? The only help google and youtube gave me was how to switch sides but that is not what I want to do.
How to monitor the USB ports of an old IBM T41?
location: linux.com - date: September 14, 2010
Besides my Macbook I got this old IBM T41 with Ubuntu 10.04 installed on it.
Currently, I'm working on developing a device driver for Ubuntu that'll monitor the USB ports of the computer, and report when a device has either been inserted or removed from either of the ports.
I have entirely read this tutorial: http://www.freesoftwaremagazine.com/articles/drivers_linux?page=0%2C0, but that's about as much experience I got with device drivers. - I'm not completely new to working in this ring level though, as I have already developed my own little GUI toy OS.

How do you close port 22 SSH?
location: linuxquestions.com - date: March 16, 2004
I'm trying to secure my box and so far i've shut down ports in /etc/rc.inet1.conf that i don't use. When i run nmap it says port 22 ssh is open. How do i close this port other than a firewall rule? I looked in the /etc/rc.d directory, but can't figure out how you shut it off. I googled and read that it is to be disabled in /etc/rc.config, but i don't have an rc.config. I have a rc.inetd1.conf where i commented out the other ports i have no use for, but ssh isn't in there. There is a rc.sshd, but i don't see an option to disable it there either.

How do you EXIT THINGS? I have to relogin to close everything!
location: linuxquestions.com - date: December 17, 2001
OK. If I do top , then I don't know what to do. How do I get OUT of top. All I can do is stop the process with shift+z, then kill it. Is there no way to just stop it? Or how about the man pages? Or getting out of Vi? Or emacs? HOW DO YOU EXIT THESE THINGS?
