I'm trying to execute some actions when there's no keyboard action in "x" seconds or minutes (after "x" seconds or minutes of keyboard inactivity), but is hard to find something about this...
and i don't know if this will make a lot of cpu usage
I've got a program that takes keyboard input with BufferedReader and readline(), but readline() is blocking so I can't increment any sort of counter to quit the application after a period of inactivity, because the program is just waiting for an input from readline(). Do I need to create multiple threads, where one thread counts down an inactivity timer, or is there some method of using non-blocking keyboard inputs?
View 1 Replies View RelatedI've paired a bluetooth keyboard and mouse with my machine using the Gnome bluetooth wizard and the keyboard and mouse work fine. Then, if I let the computer sit for a few hours and then try to use the keyboard or mouse, nothing happens. When paired with my windows machine, and I start using the keyboard and mouse after a hour or two, the keyboard takes a second or two to start working again. I suspect that it turns itself off, and then has to reconnect, and that in Linux, the reconnection isn't working properly. I've found other instances on the forums of people with the same symptoms, but never any clear answers. Does anyone know what's going on?
View 1 Replies View RelatedI would like to allow the auto-log off feature either an extended inactivity time or to disable inactivity-logouts.
I use my PC strictly at home, and have no security issues. I've set my username to no-password so that I just click [twice] to log back on. But I must do that to see the screen display - say to see what's playing on Pandora.
Can I set the auto-logout-time somewhere or disable the function?

All rolls well, but I'd like to have the component be "followed" - if there is a drag on the component, the form should be visible. I'd like to make a puzzle where the player can see the perimeter of the piece to see if it fits where (s)he'd want to drop it. Before I delve into the tons of code, I'd like to know if that (the following) can be done.
View 2 Replies View RelatedIs it possible to map the same "Present Windows - All Desktops" action which is invoked by activating the top left corner of active screens via a keyboard shortcut? I basically want to ape OSX and have an expose-like button, the screen edge works fine for now, but I would love a keyboard shortcut also. Is it possible? Also, when I set up a custom keyboard shortcut to run yast, I initially tried using the same command from the KDE menu: /usr/bin/xdg-su -c /sbin/yast2
However, when I use the keyboard shortcut to launch this command, I get problems when trying to use zypper after the initial launch using the keyboard shortcut(from yast GUI or CLI). The error basically states another instance of yast2 already exists. The problem is only with the app/repo management modules though; for instance I can launch yast (using keyboard shortcut or start menu) and access hardware info, sudo users etc, I just can't access software/repo management stuff. Even when I kill the offending PID from the CLI I still get the error and have to restart the box to rectify it proper. So I changed the keyboard shortcut command to : /usr/bin/kdesu /sbin/yast2
and this seems to have resolved the problem. My second question is what is the difference between the two in this particular instance and why does one cause problems (xdg-su) and the other does not (kdesu).
A bit clumsy subject, but I would like to make a script, which is able to send and receive email messages from CLI. The script should work like this:
1. read user input from stdin(for example a mail address)
2. send mail over SMTP(SSL, port 465) to a mail server
3. mail server sends an automatic response, script should just display this response email sent from mail server over IMAP(port 993)
At the moment I have a fallowing configuration in my Thunderbird:
Code:
IMAP mail.domain.com SSL 993
SMTP mail.domain.com SSL 465
Is it possible with 'mail' utility? Do I need to configure some sort of MTA at first(I use SUSE and I have Sendmail installed by default)? What are the steps, to get this script working?
I'm studying an OS programming book, in particular network sockets. I have two questions(2nd one is down at the bottom). There is something I don't quite understand. What if this piece of code, which sets sigpipe's default action to ignore and opens a socket:
Code:
if ((u_ignore_sigpipe() != 0) || ((sock = socket(AF_INET, SOCK_STREAM, 0)) == -1))
return -1;

I've been given one of these ubiquitous usb-sleep buttons which is basically a supersimple usb-keyboard. It's a big button that sends a SLEEP keypress to the computer when you slam it. But that is pretty boring. I'd love to remap it to do something more fun but I can't figure out how to bind to only the sleep press from the button and not from my ordinary keyboard.
The button identifies as
Bus 001 Device 035: ID 1130:600d Tenx Technology, Inc.
I'd like to know if there's either
a way of mapping a key from a specific keyboard to an action OR a way of remapping the sleep key from a specific keyboard to a new key-code or something like that.

I am trying to write a script (especially C-shell) to execute a fortran code that reads in parameters from keyboard typing. I will have to process this .F code for many times with the parameters the same for all my data files, therefore, I don't have to type in everytime I execute the .F code. But I don't know what is the command in c shell to read in a text files that contains all the parameters I want and can make the shell read in appropriately to feed the .F code.

I have a script in the works that reads an MP3 file and gets the track length. Trouble is, it gives me the total seconds, like this:
Sample Track.mp3 = 225.55 seconds
What I'd like to have is that 225.55 converted into minutes:seconds format (in this case, 3:45). How can I do this?
Is there, by chance, a fancy name to describe code that must be in a program but will never be executed? In one of my (Haskell) programs, I have some error-handling code that must be in the program to keep the compiler happy (due to the type checking). However I know that, due to the logical structure of the program, it is impossible for the code to be evaluated. I am curious if there is a technical name given to code that must exist but cannot be executed.

Code:

into my php script, it works fine. However, if I put
Code:

it doesn't (to be precise, the script still works, but myX11application is not executed). Of course, scripts are run by user "apache", who doesn't have access to X11 server and doesn't even have DISPLAY variable defined.I installed virtual framebuffer Xvfb, created a small bash script:
Code:
Xvfb :2
export DISPLAY=:2
myX11application
and called it with exec from php, but it still doesn't run since it looks like Xvfb can't start if the normal X server is running (I need that for development purposes). The reported error from Xvfb is
Code:

Is there a solution to have php running your X11 applications with normal X server running?
