![]() The system might even be shut down between it’s use, I’ll see about that later. This will run a fullscreen Kivy app and the screensaver should be steered by this app and not happen automatically. The setup needs to be a little different than the one described above. I have an (old) Watterott 2.8″ touch display I want to use on a Raspberry 3a. This “needs” (*ahem*) a Raspberry Pi with a small touchscreen as a local interactive controller. I’m working on a little something that I’ll share more about later. Side note: Chromium does not include Google’s Text-to-Speech system, and I could not get some system-side thing (e.g. If I remember correctly I also struggled a lot with getting Chromium to properly output sound to a USB-connected soundcard/speaker, but I don’t remember what I did to get it to work – I think it was about running pavucontrol while Chromium was playing some sound, and then fixing devices/volumes in there. ![]() I should consider a regular reboot, but this is running stable enough not to require that. To make the boot slightly faster and avoiding extra graphics the /boot/cmdline.txt includes logo.nologo and /boot/config.txt includes disable_splash=1 xscreensaver file for a simple blank screensaver: timeout: 0:01:00 Using xscreensaver because here it’s trivial to include in the LXDE autostart. Basically configure the raspi to autologin with graphical UI, then configure the user’s X session in ~/.config/lxsession/LXDE/autostart like this: -check-for-update-interval=31536000 -noerrdialogs -disable-features=TranslateUI -disable-infobars -incognito -kiosk The method I’m using follows what’s lined out here, or on various other pages. Intention is that this is “off” by default, turns on when the screen is touched, then allows interaction with a browser, and after some time of no use turns off again. Directly boot into a graphical screen and allow user interaction through a touchscreen. This technique should be persistant.For home automation or such. In root mode, edit the following file: /home/pi/.config/lxsession/LXDE-pi/autostart and add the following s s noblank Launch it and search for the option to disable it completely. You should find the screen saver application. Once installed, go to Preferences option in the main desktop menu. Xscreensaver is a screen saver utility for X Windows. Here are some techniques I found but I didn’t tested them yet. You can use the nano editor:ģ – Other Techniques with Recent Versions of Raspbian You need root rights to update the nf file. If you want to disable the blank screen at every startup, just update the /etc/lightdm/nf file and add in the section the following command: See section 3 for alternative techniques. It looks like this method no longer works with recent version of Raspbian. ![]() Xset s off disable the screen saver, xset -dpms disables the DPMS ( Display Power Management Signaling) and xset s noblank tells to X server to not blank the video device. You can disable the blank screen once with the following command line instructions: I successfully tested both methods with a Raspberry Pi 2 + latest Raspbian Jessie (v4.1) + 7-inch touchscreen display. By default the screen is blanked after around 10/15 minutes if no user input (mouse or keyboard) is detected. Here are two techniques to disable the blank screen on the Raspberry Pi.
