Greenlines provides a login manager theme.

Greenlines is a set of lines drawn with SVG, and a minimalistic login manager in the upper right corner.

Some of the code is based upon Pirates of Gnome, I may fix up the code later on, because some of it is not that well thought through. Suggestions are welcome.

Show Screen Captures is an extension which enables displaying screen captures of external links on a web page.

Displays screen captures of external links on a web page. Screen shots provided by openthumbshots.org.

A screenshot, screen capture, or screen dump is an image taken by the computer to record the visible items on the monitor or another visual output device. Usually this is a digital image taken by the host operating system or software running on the computer device, but it can also be a capture made by a camera or a device intercepting the video output of the computer.

Screenshots, screen dumps, or screen captures can be used to demonstrate a program, a particular problem a user might be having or generally when computer output needs to be shown to others or archived.

reset-screen is a very simple Qt 4 program that displays a simple cross hatch pattern on your monitor.

Why is this useful? Well, it makes the auto-sync feature of the flat panel LCD monitors out there both faster and more accurate (well, for mine anyways).

I have to run this every other time I start KDE so I figure others may find it useful as well.

This isnt really useful for laptop users I think, but you may need it. Who knows? :)

This is a very simple program, which a very simple build system.

fancylogin is one of the most powerful login programs available for Linux. It can do everything your old login program can do, e.g., handling shadowed passwd files, user-time-terminal/network-verification as done with HP-UX login, etc. The project adds a lot of capabilities for logging logins and support for themes to control the logins look.

History:

I first had the idea of creating a better login for linux, when i was working for IBM in the summer. a really big company had lots of 5250 terminals standing around. OS/400 would allow you (just like fancylogin) to insert an ascii-graphic with colors, etc., so all terminals were showing the companys emblem. this really looked great. so why is it, that one of the best server-systems like linux has such a boring login-screen? even Novell Netware has at least bits of color!

The more i studied popular login-programs, such as Julienne Haughs shadow-login, the more i realized that much more capabilities for security and logging are needed, in order to guarantee a secure system. fancylogin shouldnt only be a a fancy login but also a secure and very functional one. And as everybody who wants to do something on a system must be authenticated by a login, a good login-program is one of the most important keys to a secure and reliable system. fancylogin should be the answer.

The first thing i did was write a litte fancy.o with really weird configuration (the signon.*-files). then i had a look at the sources of the shadow-login-program and included a call to my fancy_prompt-routine. that was all. but as i didnt know anything about that code, i decided to take my fancy.o and write my own login-program around it, because i had a lot of improvements in mind. that was in the christmas-holidays of 1999. after those holiday fancylogin 0.99.5 was out, and the first login program that supported techniques from shadow AND from HP-UX-login (usertty). that was when Andreas Krennmair joined the team. soon we released 0.99.6, and for the first time announced it in c.o.l.a. and on freshmeat.net. on the first day of the release we got 5000 hits, and our school-server had three times the workload it usually had. that was when we put the project on sourceforge.

If i had to give a codename to fancylogin 0.99.7 i would call it "0.99.7 - the great odyssee". first we released some minor patches and fixes in 0.99.6b, but we had great plans for 0.99.7. priority number one was an improved way of configuring everything. then Matthew Wormald wrote an email doing suggestions on fancylogin. one of these were to support ANSI-files, which was the solution of our dilemma. then i worked on support for ANSI-files, but just couldnt get an ANSI-interpreted terminal together with ncurses. after a few months we decided to forget about the ANSIs, because it was too difficult to implement. Andreas Krennmair wrote flted, a program to create signon*- configurations. it should never really be released, because he finally managed to do it. in fancylogin-0.99.7-alpha2 everything was finished already, with fancylogin supporting the signon.defs and two ANSI-files. but i wanted to have everything in one file, so themes could be easily installed, and every theme-related information was in one file. so i decided to put everything into a structure, and wrote fltcreate and the neccessary modifications to fancy.o, and fancylogin-0.99.7 was finished. the first fancylogin a normal human could actually configure and write themes for!

Secure Login provides a login extension similar to Operas Wand login.

It uses the built-in password manager, but deactivates the prefilling of login forms.
Instead, you are now able to login with one click or a keyboard shortcut (ALT+N).
Just add the Secure Login toolbar button to your toolbar, or use the provided statusbar icon.
If you hover over one of the icons, a tooltip is shown, displaying the login url and the number of available logins (users).
For more than one user or login forms on the current page a selection prompt is displayed on login.
You have the option to play sound notifications (*.wav) for found login data on the current page or when logging in.
All the options can be changed using the Secure Login settings menu or the statusbar icon context menu.

Secure Login provides you with a number of Security enhancements and helps protecting you from phishing:

Disabling the prefilling of login forms prevents malicious JavaScript code to automatically steal your login data.
This is due to the fact that no login data is inserted in form fields before the user clicks on the login button or logs in using the keyboard shortcut.
To make sure you login to the right website, the second level domain of the login url is compared to the second level domain of the current page.
If they do not match a dialog prompt is displayed before login.

SecureLogin provides you with an optional setting to protect you from all JavaScript code during login.
This can prevent cross-site scripting (XSS) attacks without having to deactivate JavaScript completely.
If you enable this option, your login data will never be inserted in any form fields nor will the login form be submitted.
Instead your credentials will be sent to the login page using internal Firefox methods.
Not all login forms will work this way, e.g. not those using JavaScript routines.
Therefore, you can add such websites to an exception list.
