In other words, you only see three possible things: a black screen, a blue screen, or a red screen. Start typing again, and it turns blue again.
#XSCREENSAVER SUSPEND LOCK PASSWORD#
If you press and the password was incorrect, it turns red. When you start typing your password, the screen turns blue. The screen simply turns black when it locks. I’ve tried several screen lockers, and my favorite is slock, for one main reason: it’s super minimal. To lock the screen, first we need a screen locking program. See here for more info, as well as, of course, man xset. Once you figure out the command that you want, just add it to your X startup file, ~/.xinitrc, to run the command whenever you start X. I use Syslinux as my boot loader, so for me, I simply edit the file To make the screen go blank in console after, say, 60 seconds, you just need to pass the option consoleblank=60 to the kernel, e.g. by adding this option as a kernel parameter in your boot loader configuration file. In that case, I haven’t logged in yet, so my console screen is already password-protected.įor the impatient: just jump to the recap to see my setup. I simply want it to go blank in case, for example, I boot up my computer, walk away to make a coffee, etc., and forget about it for a while. The reason for not requiring a screen lock in console is simply because I personally almost never spend time in console (I always start X right away), so it’s really not an issue. The reason for switching from a screen saver to a blank screen in X is mainly to conserve battery life. When in X, the screen should go blank and lock after 10 minutes of inactivity. When in console (i.e. not in X), the screen should go blank (i.e. turn off, not just turn black) after 1 minute of activity.
Although I really enjoyed the many different screen savers that it came with (I’ll never forget my students’ reaction when one day in class my slides turned into a cow jumping on a trampoline), I recently decided that I wanted something a bit more minimal (and less embarrassment-prone). For many years, I used XScreenSaver as my trusty screen saver and screen locker for the X window system.
