Ubuntu 13.04 - installation Nvidia driver

Question

I have a value on my PHP page and I want to refresh it per second with setInterval().

So I actually know how to refresh values with html etc. But now I want to do the same with php values. Here is my code:

<script>
setInterval(function()
    {

<?php
$urlMachineOnline = 'http://192.168.0.150/awp/Shredder/PLCfiles/MachineOnline.html';

// get content
$contentMachineOnline = file_get_contents($urlMachineOnline);

//remove first 2 characters
$truncateMachineOnline = substr($contentMachineOnline, 2);

//remove last 5 characters
$MachineActivityMS = substr($truncateMachineOnline, 0, -5);

//Set the value to seconds
$MachineActivityS = floor($MachineActivityMS /1000);

$formatMachineActive = 'H:i:s'; 

$TimeMachineActive = gmdate($formatMachineActive, $MachineActivityS);

?>

},1000);

</script>

Ofc this isn't working since JS and php arent really great together. and in my table I just simply have:

<table>
    <tr>
        <td>Activity:</td>
        <td><p id='MachineActivity'></p><?php echo $TimeMachineActive; ?></td>
    </tr>
</table>

So the problem now is, it's only refreshing when I press f5. But now I want the autorefresh. I know setInterval() worked for html. Is it possible to get this done for php code?

Solution 1

Hit Ctrl + Alt + F1 to reach the first virtual console. Log in there, then follow the instructions.

To get all the relevant stuff, including the kernel sources and kernel headers run next command

sudo apt-get install build-essential linux-source linux-headers

If the package linux-headers is not available, try running the command by specifying the exact version of the headers with:

sudo apt-get install linux-headers-`uname -r`

Next, install the current Nvidia driver:

sudo apt-get install nvidia-current

Once the installation completes successfully, check if the Nvidia driver is loaded:

sudo /sbin/lsmod | grep nvidia

If it's not, you will need to manually insert into memory. First, make sure all kernel module dependencies are satisfied and resolved:

sudo depmod -a

Then, load the driver:

sudo modprobe nvidia_current

This should succeed and the lsmod command should show it's loaded, but the usage count will probably be 0, because nothing will be using it yet. You will need to restart the graphics environment to actually benefit from the driver:

sudo /etc/init.d/lightdm restart

This will restart the graphics environment, you will see the Nvidia splash, and you will load into a desktop that has the Nvidia driver running, and all that. Your problem is now resolved.

Solution 2

It is easier to follow this approach:

1. Click the gear icon in the top right corner of the screen.
2. Click "System settings..."
3. Click "Software & Updates" in the "System" category.
4. Click on the "Additional Drivers" tab and select the proprietary driver.
5. Click "Apply Changes".

Reboot, job done!

@zendessert This option you described here is all greyed out for Additional Drivers and says "No proprietary drivers are in use."

You need to write the value to <p id='MachineActivity'> using javascript rather than <?php echo $TimeMachineActive; ?>

[Anwar]

Ofc this isn't working, JS doesn't bother PhP, it's just you didn't wrote correclty your JS.

[Hammad]

Preferred way of doing so to use Ajax rather than mingling JS and PHP code.

[Hammad]

Yes you can do that but better not do that. First write a ajax function in setInterval method calling $urlMachineOnline. Whatever is the result from that ajax response is write that value to <p id='MachineActivity'>. In this way your value will be refreshed after 1 second.

Do this in tty1 (first virtual console), Ctrl + Alt + F1

[user155915]

Yes, I'm in tty1 mode, try to reinstall from cd. Thank you a lot!

[user155915]

Solved only after a fresh install. Thank you a lot.

This just ripped me a new one. I did it in the gui like an idiot and now I can't get my desktop back. I can open windows with hotkeys, but other than that she's cashed.

[Abiologist]

Same effing error "FATAL: Module nvidia_current" not found... in 13.04. Do I really have to reinstall? This is a FRESH install as is... nothing has been installed.

[Radu Rădeanu]

@JoshuaRountree Have you tried all of these from tty1?

[Abiologist]

I'm sorry, is that what appears after you hit CTRL+ALT+F1?

[Radu Rădeanu]

@JoshuaRountree Yep...

[Abiologist]

Then yes, that's the only place I tried it...

[Abiologist]

Tried this now, howopensource.com/2012/10/… and same issue :-/ Assuming my graphics card is bad?

[Abiologist]

Did the restart on lightdm and I get the plain desktop with no left bar or top bar.

[Abiologist]

Also, when I type sudo modprobe nvidia_304 it says ERROR: could not insert 'nvidia_304': No such device

[Abiologist]

FYI I'm running 8600 GT?

Relating to the new problem with plain desktop see askubuntu.com/questions/17381/…

@Hammad I can't mix JS and php values with eachother can I?

[Anwar]

In fact, what you've done result in some random text, inside your SetInterval function. You should store the result of PhP in several JS variable using var myVar = "<?php echo something; ?>"

[Bart]

Yea it kinda needs to auto refresh... not by a button or something

[Asit]

You don't need to add button. Here while condition in always true, so it will run infinitely.

[Bart]

When I use this I get another field in the topleft of my screen and it shows the page. and it kinda freaking out since it loads a new page in it again again again again and again... :P so you get something like setting 2 mirrors in front of each other.

[Bart]

It's not working. But it doesnt show any error when I inspect it.

[Bart]

And how do I use this code, whats should I set in the $f();? the $seconds will just be 1 second... so you dont have to add the MS > second conversion

[Hammad]

Please make sure you include jquery library in you html document.Also value-generation.php must be placed in same directory in which your file running script tag is placed

[Bart]

I've got the 2.1.3 jquery included. What do you mean with the file running script tag? Both files are in the same directory map (if that is what you mean).

[Bart]

If I remove the 2 parameters and create a function of the php code it crashes. Since it is just infinite looping. This doesn't work.

[Bart]

replace $("#MachineActivity").next().html(response) with $('#MachineActivity').html(response) and it works like I want it. just counting up the value per second :)

[Bart]

If you change your answer with what I said above. I will give you the correct answer mark.

[Hammad]

Thats good...I said so because there is slight error in your markup. Anyways if its working for you can consider accepting the answer. :)

[Calos]

The problem is refresh every second and setTimeout() runs only once.

[borchvm]

Code-only answers are considered low quality: make sure to provide an explanation what your code does and how it solves the problem. It will help the asker and future readers both if you can add more information in your post. See also Explaining entirely code-based answers: meta.stackexchange.com/questions/114762/…

[Sebastian Speitel]

@Calos and after the reload it get's called again.

[Calos]

@SebastianSpeitel mentioned in the title Refreshing part of my php page, which means that just need refresh some content, not completely reloaded.
