My devices all reside in my home (I’m Retired) so physically they are all fairly secure, but I still enable access security measures in the event of theft. This does not happen very often, and I keep the Settings interface running minimized to the taskbar, so I don’t forget to revert the changed settings when I’m done. Whether in Windows, or one of my GNU/Linux distributions, I disable screen blanking/locking only when performing some procedure that will require a long period of inactivity as I wait for it to complete. Please do check out my extensive Linux help area for lots of additional tutorial content while you’re visiting. Pro Tip: I’ve been writing about Linux since the dawn of the OS. You can tweak your settings as desired, and now you know where to change ’em! I recommend something more like 10 minutes for screen blank and another 5 minutes for screen lock. Perhaps more important than the screen blank delay is the “ Automatic Screen Lock Delay” and, again, there are a lot of options:Īt the maximum, you can set it to an hour, which, if you have your screen blank set to 10 minutes, means that there’s a 50 minute window when the computer looks off and secure but is open to any user with a keyboard tap or mouse wiggle. Now that I think about it, do you want your Linux system logged in and unattended while you’re heading to the breakroom for a cuppa joe? Note that “Never” is redundant with you simply disabling Automatic Screen Lock, another setting that I don’t recommend you enable. Plenty of time to walk into the breakroom and grab a cup of coffee without it going to sleep, right? Unless your system is in a secure location, I don’t recommend choosing “ Never” (and probably not even then) but if you’re finding that your current setting is just too short, change it up to 10 minutes or even 15 minutes. I like to think of it as “time to sleep”. The first thing you can change is how long you can be inactive before the screen blanks. So what should you change? Let’s go through the list… WHAT LINUX SCREEN LOCK SETTINGS TO CHANGE Click on “ Screen Lock” and, finally, we’re in the right place to make some changes: Lots of great settings to adjust for your own preferences, but let’s instead go to “ Privacy” on the left side…Īlmost there. The Settings program remembers the last thing you checked so it’s hard to know where it’ll start out. Start in an Ubuntu computer by using the handy “Settings” shortcut from the top right of the menubar: Modern Linux systems have nice Settings utilities and that’s what you need to fine-tune your sleep security settings. Let’s get into it! WHERE TO FIND SCREEN LOCK SETTINGS IN LINUX Biggest difference? If your system is asleep, all your apps and programs are still running, but if you log out, everything shuts down and will need to be restarted when you log in again. There are a couple of relevant settings in this context, starting with your password: Is it good, complex, and hard to guess? Great, that means it’s probably a pain to enter each time your screen locks up, right? In addition to that, there’s sleep versus logout, which aren’t the same thing. Not to mention Linux systems, which have had strong security since the first boot. This is true for every smart device too, actually, from your smartphone to your tablet, Mac, PC, even a Chromebook has settings and options. Typically you have to use a computer for a few weeks to really understand if it’s too quick to lock, too open, unlocked through lunch, or somewhere neatly in the middle. Dialing in the precise security settings each of us wants for our computer can be tricky.
