To make it so your screen locker works with XSecureLock, there are only two things your program needs to use. API wise, Cairo is really similar to Apple’s CoreGraphics library, which I was already really used to. For graphics, I used the wonderful Cairo Graphics library. I hadn’t written a big C program in a long time, so I thought it might be fun to do it again. That being said, I expressed no creativity with regards to the programming language choice and just went with C. All you need to do is return 0 from your main function on success, or non-zero on failure. The cool thing about each part being separate executables is that you can write each piece in whatever language you choose, because there aren’t even any dependencies between them. Therefore, a custom screen locker would fit in right between the authenticator and XSecureLock itself.
Lastly, XSecureLock provides an authentication program, intended to be forked from your “saver”, which is responsible for asynchronously doing the work of authenticating with libpam.

XSecureLock refers to this as the “saver”, because it assumes you’re using a screen saver to show the password dialog (for instance, XScreenSaver provides this functionality via a shared dialog window for all hacks). The first is the actual xsecurelock executable, which blanks the screen, captures all input from the keyboard and mouse, and continuously prevents any other window from appearing on top of it and stealing focus. The modular part of XSecureLock is that it’s separated into three separate executables, launched in order. XSecureLock was designed to do the “heavy lifting” for you with regards to handling the challenges/gotchas with actually making sure your screen is locked, and no other program in the background can steal focus.

After examining the source code a bit, I was also pleased to discover just how modular it is. I had been using XSecureLock for quite some time now. I’ve been getting really into Linux on the desktop recently, so I thought this would be a great opportunity since I now have the ability to change my login screen to whatever I want.

I think they have to create a poll or something for that.Moments before the protagonists from the movie Hackers work together to overload the Gibson–after rollerblading through New York City via an undisturbed route of compromised traffic signals–each one of them rolls into a phone booth in Grand Central Station and boots up their laptop. Screen-savers are still a solid point for many to leave mate-screensaver. Now that we have Ubuntu Mate which uses LightDM, Light-Locker is logical choice because it was sort of meant to be used ensemble with LightDM and they both integrate nicely.
I also think that light-locker could be tweaked to support that as well.Īs for the current state of events I don not they integrate lock screen wallpaper in mate tweak simply because the screensaver uses elevated privileges (pointed out in the link you shared, the one by I think they would rather do it as a part of LightDM Greeter settings (possibly renaming that to LightDM and Screensaver settings or something).īack in the day Ubuntu did not use LightDM (I’m pretty sure it used GDM as a part of Gnome2 environment). Legacy screensaver are fun a lot of people may want to preserve those, that’s true. Retrospective future is their moto so I reckon some compromises would have to be made at some time.
