I have a script I would like to have automatically invoked every time the screen is unlocked. Does Ubuntu provide some support for users who wish to do this?

Is there a way to see what time I unlocked the lock screen (by typing the password)?
View 5 Replies View RelatedI'm running Fedora 14 and set the screensaver (in System>Preferences on the Gnome GUI) to activate after the computer is idle for 30 minutes. After the screensaver is activated, and a press a key or the mouse, the screen is back to normal -- no problem.After the screensaver has been activated once, however, it comes back on very quickly -- usually in 2 or 3 minutes if the computer is idle. The only way I have found to correct this (and set activation back at 30 minutes again) is to log out and back in again.How can I correct this, and automatically set screensaver activation back at 30 minutes each time the normal screen is reactivated?
View 1 Replies View RelatedI'm a bit worried about "too many mutexes" in my little curses-based app and would like to get confirmation/opinions that I'm doing this right. I've got an array: int nums[60] I've got 61 threads. 1-60 are doing math on the value in their array index (ie: thread1 increments nums[1], threadN increments nums[N]), then sleep(1) The 61st thread is my curses thread which does a for-loop over the array and prints out all the values to the screen, then sleep(1)
Right now, I've got 1 mutex which gets locked/unlocked each time one of the 60 threads needs to update its array-index with a new value, and the 61st thread locks the same mutex just before the for-loop beings reading the values and unlocks after ending the loop.
My questions:
A) Does the above seem OK? (I know it's ok, cause everything works right now but would like opinions on it)
B) Do I even need the mutexes since 1-60 only ever update their own index and 61 just reads?
C) If I do need the mutex protection, is there a better, more efficient way?
Is there a way to set Linux to automatically log in to a specific user account and at the same time lock the screen? I want to save time and trigger various software that always should start up on boot, while leaving the computer unattended during startup (extra important and practical for remote control boots), by enforcing a 'screen lock' so that no-one can see what happens behind the login screen without entering the login credentials.

I don't know about your computer but when mine is working properly no process is sucking 95%+ over time. I would like to have some failsafe that kills any processes behaving like that. This comes to mind because when I woke up this morning my laptop had been crunching all night long on a stray chromium child process.
This can probably be done as a cron job, but before I make it a full time job creating something like this I'd thought I should check here. :) I hate reinventing the wheel.
I have an old computer and BIOS counts the time slower than real. So, how can I set my OS to update the time automatically using the internet? If it updated the time only during booting, it would be enough.

I've been a happy Arch Linux user for years now. Recently, on my eee 1000he (an Atom netbook with intel GMA graphics) I've been seeing strange things. After it has been on for some time (usually hours), the screen starts to jitter, just for a fraction of a second, every now and then. After this has happened some times, the screen goes black (one time it went red). The backlight is still on and I can still ssh to the machine which reacts normal appart from the black screen. I can only regain the screen when rebooting. What could this mean? Is it hardware or software? X logs don't shown anything weird, where should I look? I haven't found anyone with the same problem on the net.
View 4 Replies View RelatedI like the convenience of having a music player that manages the placement of my music files based on the tags of the files, sorting into a root music folder with Artist/Album/01 - Track Title.mp3 sort of hierarchy. Previously, I was using Banshee for this feature, as even most of the other gui music players don't have this library management feature. Now, I've been trying to use console-based applications, and I have been using mpd + ncmpcpp fairly successfully. When I download new music, it is downloaded to a specific folder, and that's not part of my music collection. My previous workflow would be to open a gui filemanager at the downloaded folder, and drag and drop those songs onto banshee, which would then make a copy of those files in my library hierarchy. Currently, I'm doing the same thing, using Banshee only as a sort of import program, then closing it and updating my mpd database, and there we go.
If at all possible, I'd like to automate this to something where I can define a watch folder, and when some magical program sees new music in said watch folder, it identifies the correct place for the files to be copied into my heirarchy, renaming folders and files to the correct format. I know I've written a lot describing, but I don't actually think this too uncommon a task, and I'm wondering if anyone has a solution for my problem.
i wanted to know how can I make my programs or script automatically start at boot time ,for example if I restart my server at any time they start at boot time automatically with no need to any body to start them.

Linux bash inline command to execute a program and limit the resource.As I know, to limit the resource I can use ulimit command.But, the problem is when I set the CPU time limit 1 second, and then I want to execute another program with CPU limit 2s, the ulimit command return an error like this: bash: ulimit: CPU time: cannot modify limit: Operation not permitted and absolutely my program killed in 1 second.So, How can I make the second program running with the CPU time limit 2 seconds?
