Describe the bug Issue noted on a Raspberry Pi 4, running Buster using both the stable kernel and the current bleeding edge.
The X dpms settings are active. The screen blanks after the defined timeout but the backlight stays on. Have no other display devices to test with. Expected behaviour Screen blanks after 5 miniutes. Backlight switches off when screen receives no HDMI signal. On Pi 4 it blanks completely, then the backlight switches on which is no so good. System Pi 4. Debian Hopefully, this can be fixed via a firmware update.
Possible but needs a little though to avoid problems where the display doesn't come back or causes a lockup. I think I can cope with turning the screen off for the time being :- The irony for me is that I look after Pi's running signage at work and where they use TVs as displays which they do because budgetholders buy whatever TV is on offer I've had real trouble sometimes stopping them from switching off.
And now at home I have the opposite problem! Still love Pi's though. Hi, I have what appears to be the same issue. Not on Pi4, but on Buster. Some time after booting, the screen blanks. I can then still ssh into the box and even make cvlc play back videos. But the gui is gone. All is pitch black. Please let me know if you see the same "Xorg Tainted" stack trace.
If not, I should file a separate issue. A person just posted a fix for the screen blanking issue. I'm picking a for the time being The warnings are still here also.
I need a way to show black screen by running command in console by using SSH connection. Monitor should not go to standby I just need a black screen to hide everything that is on the screen.
Screen should be black until I give another command to show screen content. This may result in the monitor itself turning off, depending on the monitor's settings, because it's not getting any signal. Some TVs or Projectors may display an error message about no signal. Method 3 : This does not apply to RPi 3 with standard Raspbian, but some specialized situations and the original Pi might be able to use this alternative depreciated?
In all these methods, the part about -display :0 is redundant if your terminal is visible on the display you are trying to control. Turn black screen saver on: xset -display :0 s blank xset -display :0 s reset xset -display :0 s activate. You don't need command xset -display :0 s blank and xset -display :0 s noblank if the default setting is blank. Sign up to join this community. The best answers are voted up and rise to the top.

You might need to set the screen's default state to blank I didn't : xset -display :0 s blank Turn the monitor to it's default state black hopefully : xset -display :0 dpms force off Turn the monitor back on by hitting a key, moving the mouse, or using this command: xset -display :0 dpms force on Method 2 : Turn off the HDMI port and back on.

Turn it off: tvservice -o Turn it back on: tvservice -p The monitor might be blank or checkered until you force it to display: xset -display :0 dpms force on Method 3 : This does not apply to RPi 3 with standard Raspbian, but some specialized situations and the original Pi might be able to use this alternative depreciated?
Find out what the monitor's name is by running: xrandr -display :0 -q We'll use the name CRT1 in this example to turn it off: xrandr -display :0 --output CRT1 --off And turn it on again: xrandr -display :0 --output CRT1 --on In all these methods, the part about -display :0 is redundant if your terminal is visible on the display you are trying to control. Best of luck!
It only takes a minute to sign up. The mouse acceleration seems totally crazy. Well actually, initially it was disabled and the mouse was really slow. I upped the 'Acceleration' and 'Sensitivity' in the settings and it now does accelerate, but the acceleration seems to be binary, i.
Raspberry Pi (4) Kiosk / Wall Display / Dashboard
Is there a way to get a nice smooth acceleration curve like Windows has? OS X is also pretty awful in this regard.
Also does anyone know where the code that does the acceleration is, so I can get a look at the algorithm? Aha I found the answer here and the actual documentation here. Basically a really simple algorithm is used unless you set the threshold to 0. I set the acceleration to 2 and it gets pretty close, though it is still far from as good as Windows. First install xinput:. You want the actual mouse device id, not the "Virtual core pointer". Change the device accel profile from 0 the default which chooses between polynomial or idiotic depending on whether the threshold is 0 or not.

Featured on Meta.Recently one of our clients approached us to develop an application that would run on a Raspberry Pi to use in kiosk's throughout their facilities. We ended up writing a web app in Angular that they would run via Chromium. One of their requirements was the Pi shouldn't go to sleep and appear always-on to their users.
While we've already successfully launched the system, I have a feeling others will want to use this same functionality in the future. So, without further ado, here are the steps we used in setting up each device to run in kiosk mode:. To do this we'll be editing the autostart file in. So navigate to it with:. The Pi's WiFi will also go to sleep if we don't change it. Modify it by editing the rc.
All that's left is to reboot your Pi. Once it restarts you'll load directly to Chromium viewing your local application. Menu Home About Talks.
We'll also be using the Pi's default OS of Raspian. Prerequisites First, let's install some prerequisites. Turn off the screen saver and hide the cursor While you're still editing the autostart file, add the following: xset s noblank xset s off xset -dpms unclutter -idle 0. Stay awake Now to keep your Pi from falling asleep we'll edit the lightdm. If you find any "gotchas" or improvements to the steps above be sure to leave a comment!
I like this tutorial, however, there is no longer an lxsession directory in the user home directory.
The only directories in. Should I be editing this file?The Raspberry Pi 4 has some respectable specs is quiet, displays up to 4k and has Wi-Fi which makes it a pretty great dashboard display source. When you create a dashboard, aim for something that can run as a website and that takes care of refreshing itself, otherwise you can also make whatever browser you choose take care of that.
Per default your Raspberry Pi, like a regular computer, will put a screen to sleep if it does not detect mouse or keyboard input for a while. You can set the output display by setting the DISPLAY environment variable with either specifying it before running a screen related command. Technically you could use [xdotool][xdotool] to achieve this, but that will introduce some timing and more complexity.
Chromium on the other hand comes with plenty of cool command line options that are very useful to us. Ideally, it should open the raspberry pi website, otherwise, see troubleshooting. To remotely update or reboot your little dashboard pi, you can use ssh after enabling the SSH server through raspi-conf.
Now you should have a super cool wall mounted, 55 inch wall display, displaying a website of your choice, that even in case of a power outage will power back up just fine. If you run into any issues setting this up or operating this, please check the troubleshooting section below and reach out! If you change the hostname of your raspberry after starting Chromium for the first time, it will throw an error like.
The easiest solution to this is to connect a keyboard and hit enter, that should fix it permanently. SSH into your raspberry pi and keep htop open. Keep an eye on the consumed memory and swap space right underneath. I set it to which turned out to be excessive.

Can you give me some hints? This may help. How can I set the file system to read only? I used such a system for several month and then the SD card gets some problems.
I have added the line as you said but I only get the first chromium windows to open. Do you have any tips?Our mission is to put the power of computing and digital making into the hands of people all over the world. More from the blog.

If you cannot find one, please post your problem, providing as much detail as possible. To save time, you can get a card that is pre-installed with NOOBS or Raspbianalthough setting up your own card is easy. For best results, use a display with HDMI input; other types of connection for older devices are also available.
Wireless keyboards and mice will work if already paired. For keyboard layout configuration options see raspi-config. We recommend using the official Raspberry Pi power supplywhich is designed specifically for Raspberry Pi. They are not suitable for use with the Pi 3 or 4.
USB wireless dongle Only required if you need wireless connectivity and are using an older model without built-in wireless functionality.
Audio lead Audio can be played through speakers or headphones using a standard 3. Without an HDMI cable, an audio lead is necessary to produce sound. No separate audio lead is necessary if you're using an HDMI cable to connect to a monitor with speakers, as audio can be played directly through the display; but it is possible to connect one if you prefer to have the audio played through other speakers - this requires configuration.
