"Chokri"  commented on the post "Installing an Ubuntu Linux Hardy 8.04 LAMP and FFMpeg Server With a GUI – LAMP installation with cgi-bin", asking:

"...I have trouble while installing ffmpeg-php, I downloaded the tar file but while executing the make command, I obtain stop, what to do?..."

Well, it's been a while since I played with fmpeg-php on Ubuntu 8.04, I've since (about a year ago, if I remember correctly) installed a 9.04 based Ubuntu LAMP server. I use that server as a local development server for WordPress based sites, video based sites (as well as traditional xhtml sites), etc.

Without too much further (verbose) discussion, here are the commands I used to get this server up and running (on Ubuntu 9.04). It's still working today, and is a great WordPress and site development environment!

Install your base 9.04 server as is. DO NOT select LAMP server install.

Then start getting the tools and services you need installed...

Video sites will need the flvtool (Yamdi is a Meta Data injector for flv):

sudo aptitude install flvtool2 yamdi

Of course we'll need a database:

sudo aptitude install mysql-server mysql-client libmysqlclient15-dev

Now we need a web server:

sudo aptitude install apache2 apache2-doc apache2-mpm-prefork apache2-utils libexpat1 ssl-cert

Let's get some of the plugins we'll need (ffmpeg-php, for example): Read more

Restore Missing Panels in Ubuntu

Tess from the USA asks:

"...I am having trouble viewing my menu bar that usually appears across the top of my screen. The volume control used to be here and now I don't get volume at all. How do I get the menu bar to reappear?..."

1) Try this command in Terminal:

metacity --replace

2) If the above command did not work, try the following:

"Menu bars" are called "Panels". Try right clicking on the bottom panel and selecting "add new panel" (that's the wording, if memory serves me correctly). Drag the new blank panel to the top. Then add the applets you want to that panel.

The applets you want might be:

Quit applet at the right
Volume control to left
Network monitor to left
Notification area and then user switcher.
On the left side of the panel, add the Menu bar applet.

I hope this helps!

Note: An afterthought, maybe it's an issue with Compiz or with your system hibernation? If so, try the command: killall gnome-panel and see if that (restarts and) restores the visibility of your panel?

Enabling Automatic Login in Ubuntu

Harvey from the U.S. asks:

"...Just upgraded to 10.04, so am having to log in each time the computer suspends/screen locks. I am the only one with physical access to this computer, so prefer to configure so that password is *not* required to bring the screen back up after suspend. How do I configure this change? Have been unable to find answer on this site or via GoogleLinux..."

I never turn passwords off as this poses a potential security risk. You may be the only one using your PC, but I'll bet that you surf the Internet? If so, turning the password requirement off is almost like hanging a "help yourself" sign on your PC. Because, (unless I'm mistaken?) no password would be required to install things on your PC, leaving sites you visit the potential to install good and "bad" things on your PC.

Nevertheless, have you tried the following commands in a terminal?

sudo visudo
%admin ALL=(ALL) ALL
%admin ALL=(ALL) NOPASSWD: ALL

I'd suggest a better way to go is to enable the Automatic Login feature for Ubuntu. You can do it this way (using the GUI):

System -> Administration -> Login Window
Enter your root password at the prompt.
Select the "Security" tab.
Check on "Enable Automatic Login".
Use the dropdown menu to select your username.
Click the "Close" button and you're done.

I hope this helps you!

How to Uninstall .deb Packages – Reader Questions

March 26, 2010 | By: UbuntuLinuxHelp | 1 Comment
Posted in Q & A - Ubuntu

Jake from Germany asks:

"...I downloaded the new .deb package from Opera... and I want to uninstall it because it will not load any web pages, making me crazy... how to I uninstall it?"

I'm assuming it was a .deb package that you downloaded directly from the Opera web site. (As a side note, I had the same issue with Opera, in that it refused to load web pages on a local web server - I also removed Opera).

To uninstall any .deb package, use the following syntax:

sudo dpkg -r <name of package>

So... to remove an Opera .deb installation, the command is:

sudo dpkg -r opera

Don't forget to remove the hidden .opera directory inside your home directory! Doing so will give you a "clean" start if you want to reinstall Opera.

I hope this helps.

Upgrade Ubuntu Firefox to Version 3.6 – Reader Questions

Erica from Canada asks:

"... I'm using Ubuntu 9.04... the "Check for Updates" in Firefox is grayed out and apt-get does not upgrade Firefox... I'm stuck at 3.0.18, how can I get upgraded?..."

This is an issue, I've encountered before. The newest versions of Firefox are not yet in the repositories, and the "Check for Updates" is disabled on purpose. I tried upgrading Firefox via PPA's on a couple occasions, butthe updates failed and I ended up with broken packages! In my opinion, the following steps might serve as a safer way to upgrade.

In your existing Firefox version (3.0.18), install the following extension manager, named FEBE, in case something happens to your extentions, you'll be able to reinstall them:

FEBE: https://addons.mozilla.org/en-US/firefox/addon/2109

Use FEBE to backup your extensions.

Also, just in case something happens to your saved passwords, you can back those up as well with an extension named "Password Exporter": https://addons.mozilla.org/en-US/firefox/addon/2848

Backup up your passwords.

Finally, don't forget to backup your bookmarks in case something goes wrong.

In a Terminal, run the command:

which firefox

You should see this answer displayed:

/usr/bin/firefox

This guide is based on the pathing above. If the steps below are not followed properly, then this will not work! ALWAYS make sure you have BACKUPS of data you do not want to lose, in case something in your system goes terribly wrong.

Now, let's use the Terminal to move into Ubuntu's temporary (working) directory:

cd /tmp

Download  Firefox 3.6 for Ubuntu 9.04 (Jaunty):
wget "http://download.mozilla.org/?product=firefox-3.6&os=linux&lang=en-US"

(The above is for the North American version, you can change that to meet your needs).

Extract the contents:
tar xvjf firefox-*.bz2

We are going to copy the new version of Firefox to a directory called "firefox-3.6" (instead of "firefox"), this way we can  revert back to the original Firefox 3.0.18 is needed.
