How can I disable an integrated webcam?

Hi @ all!
I got Arch Linux running on a Samsung Q45 Danyal here which works pretty fine.
Since I'm trying to run it at the least powerconsumption possible when on the road
I wrote a small bash-script to handle things:
#!/bin/bash
hal-disable-polling --device /dev/scd0
echo 5 > /sys/bus/pci/drivers/iwl3945/0000:02:00.0/power_level
mount -o remount,relatime /
hdparm -B 10 -S 12 /dev/sda
echo 10 > /sys/module/snd_hda_intel/parameters/power_save
Now when I'm running powertop it says that I should activate USB-autosuspend
since my webcam causes some serious amount of wakeups (about 1.5 W less with
USB-autosuspend on). The thing is - I don't need that webcam at all and I didn't find
a way to integrate this option into my script, so I always run my script (I integrated it
into /etc/acpi/events/battery and lm_battery, but it isn't executed automatically, so I
have to start it by hand all the time) and then powertop to disable the webcam/activate
autosuspend when on battery.
Is there a way to disable the webcam completely, so I wouldn't need to deactivate
it at all? Or how can I integrate USB-autosuspend into my powersaving script?
Another point would be firefox - it causes about 35% of wakeups when idle...thats
definately too much in my opinion - any ideas about that?
A last question would be - how can I deactivate the display? My last notebook had
such a fancy Function-Key doing that for me...with this one this isn't the case (at least
I couldn't find one). Is there a way of defining my own shortcut to disable/reenable the display?
Lots of questions I know...and I appreciate every help and suggestions/improvements
for my powersaving-script

Could you help me find out which module I have to blacklist?

How can i disable my iMac webcam green led ?

i work in night. i need to turn off webcam green led , because make hurt for my eyes.
how can i disable my iMac webcam green led ?

I believe the LED cannot be disassociated from the camera being on. This hard wiring is important to protect the user from being videoed without their knowledge.
If the small green dot hurts your eyes, you should see an optometrist who may be able to help your heightened sensitivity, with special glasses of some kind.

Where can I find the integrated webcam for my HP G62t-350 Notebook PC?

Just like the title asks, where can I find the integrated webcam for my HP G62t-350 Notebook PC? I have what looks like a rectangle in the top center of the screen/lid, in the bevel, but I'm not sure of how to get it to work, or if it's even able to work! I've seen pics of where there is a gray circle or dot in the middle of that rectangle, but I'm not able to see if I have one or not. Would someone please help me out here?

How can I disable Firefox from automatically opening on system startup on my Mac - unchecking the "open at login" does not work?

We have Firefox 10.o on our Macbook Pro OS X 10.5.8. I prefer using Firefox as my browser but my husband prefers Safari for now because of a long history of bookmarks and saved information he doesn't have time to re-do. He is tired of Firefox automatically opening when we start up the laptop, and even when we uncheck the "open at login" it still opens at login every time. He is about to uninstall it because of this. How can we disable? It does NOT show up in our account on the Mac OS as an application that starts at login, so we can't disable it there.

For those of you running Windows, I found this on another site. (Unfortunately, not before getting totally disgusted and switching to chrome.)
1. click start (or the windows flag button at the bottom left) 2. in the "search programs and files" or the RUN dialog box, enter "msconfig.exe" or "msconfig". 3. That should open the system configuration program. 4. click the "Startup" tab at the top of the opened program. 5. Under the "startup item" column, look for Mozilla firefox. 6. uncheck that one. 7. Click OK or apply. 8. click "exit without restart". 9. you're good to go.

How can i disable imessage from automatically starting up when i turn on macbook air?

how can i disable imessage from automatically starting up when i turn on macbook air? i dont know my imessages to pop up on my laptop when it turns on. But i dont want to disable imessage totally on my macbook.

Welcome to the Apple Support Communities
First of all, check that Messages is closed when you turn off your MacBook. This is so important because, by default, OS X will reopen all opened apps the next time you start your Mac.
Apart from that, when you go to  > Shut Down, or  > Restart, in the window you see to restart or turn off your MacBook, unmark "Reopen windows when logging back in". This will avoid that your Mac opens all opened apps the next time you start the MacBook, so Messages won't start automatically at startup

The windows of the Windows bar are already a form of tabs, so I don't need them in Firefox. How can I disable them completely from Firefox 23?

RE: TABS ARE WINDOWS!
The Windows bar already functions as a tab bar. Those tabs are called "windows." So, I find Firefox tab windows superfluous. How can I disable them completely from Firefox 23? I don't need what is essentially TWO windows bars covering up the entire width of my widescreen monitor's image! I already have a Windows bar at the bottom of my screen and, if I really wanted to, I could change ITS position to the top of the screen, so that it would LOOK like the Firefox tab windows bar. Firefox TABS are, essentially, a superfluous SECOND WINDOWS BAR.
Here are my reasons for why I'd rather use Mozilla's Firefox, than Microsoft's Internet Explorer or Google's Chrome. I love and admire Firefox for Mozilla's intent on good security, for Firefox's Personas add-on, and for Firefox's free use of the Ad-Block add-on which, as you know, has the distinct virtue of reducing screen clutter--the last of which is my motive for wanting to get rid of the SUPERFLUOUS Firefox tabs "windows" bar. I am dreadfully sick of companies forcing miscellaneous bars (mostly representing marketing campaigns trying to sell me something) into my browser (and down my throat) every time I download something. (In case you haven't guessed, I am deliberately referring to your Firefox tabs bar as a "Firefox tabs 'windows' bar," because TABS are WINDOWS!)

Let me clarify even more. The Firefox add-on you mention does not remove "tabs" windows. It only HIDES the "tabs" bar when there is only one "tab" in that window. It DOES NOT end "tabs." It does not turn "tabs" off.
I know this, because, even with the add-on you recommend, the "tabs" bar often re-appears when I open a link, which--for some unknown reason--Firefox defaults to opening in a second "tab" within the same window, rather than putting it in a new Windows bar window. This, of course, disregards what I want to happen.
I want to use my Windows bar to control my windows. I do not want my Firefox browser controlling my windows--which it calls "tabs." Can you tell me how to shut off "tabs?"

How can i disable a submit button and execute submit_action method on click

Good Day,
On my page I have a submit button that execute the submit_action method of the page backing bean that submit data captured on the page into a database and activate another class that send mail at the same time on a click of the submit button,the mail process takes a while before returning back to the page.I was able to disable the submit button to prevent the user from keep click while the process is running but the issue is on clicking the submit button it only disable the submit button without executing the submit_action method of the page backing bean.How can i disable the submit button and execute submit_method of the backing bean at the same time.
Thanks in advance.

I tried this out on one of my pages to see if it works.
First, I added the following JavaScript to my submit button's onClick event:
this.disabled=true; return true;When I clicked the submit button, it was disabled but the form was not submitted.
I deleted the JavaScript from the onClick event and added the following JavaScript to the form's onSubmit event:
var button = document.getElementById("form1:submitButton"); button.disabled=true; return true;When I click the submit button, it was disabled and the form was submitted but the button's action method was not called.
The next thing I tried was to change the onSubmit event code:
var button = document.getElementById("form1:submitButton"); setTimeout("button.disabled=true", 500); return true;This seemed to work. The difference was that I added a 1/2 second delay before disabling the button.
See if that works for you. If not then I'm fresh out of ideas.

How can I disable awesomebar search/keyword suggestions on FF 3.6?

I am on FF 3.6. I'm trying to find a way to disable the AwesomeBar search/keyword suggestions. I have gone through tools -> options -> privacy -> location bar. I have tried setting the location bar set to show only history, bookmarks, or even none, but it still shows keyword search suggestions. How can I disable this?
I have also tried from about:config, setting maxrichresults to 0. Again, that is not what I'm looking for. I want it to show history and bookmarks, but I do not want keyword search suggestions.

I'm pretty sure the poster doesn't want to disable the keyword search functionality. What they want is for keyword searches to work, but just not be displayed (or at least not displayed as the automatic first option) on the list of location bar suggestions when typing a new URL.
In their words, "I want it to show history and bookmarks, but I do not want keyword search suggestions."
That was how keyword search bookmarks worked in FF3.5, if I recall, and I too would like that behavior back. I haven't found any way to train the awesomebar to not show me keyword search bookmarks.

How can I disable iPhoto automatic launch?

Hi,
I do not use iPhoto to import my digital images. How can I disable the automatic launch when I plug my camera or card reader?
Thanks!

Hi Paul,
To do this just open Image Capture, open its preferences and then under the general tab you can select the option of "When a camera is connected, open:"
Just select no application and that should do it.
