Raspberry 7" display on RPi4

[Fredothegreat]

was an old built of volumio but the new 7" display I bought didnt work so i did the following
1 install new Trixie o/s on a different sd card and the screen works fine even from boot I can see the logo etc and the tough works when on home screen so all good.
2 wiped sd card and installed fresh volumio o/s from raspberry image writer unsure of version but the updater says its the latest
3 installed latest plugin for touch display 3.5.1
4 read many posts on this from various people tried a few changes to the userconfig.txt but alas
still now screen
can anyone help please?
many thanks

Hey @Fredothegreat,

Your report is missing critical information required for investigation. The Trixie test confirms your hardware works, so this is a Volumio-specific configuration issue - but I cannot diagnose without proper details.

Critical ambiguities:

1. Volumio version unknown

   • “unsure of version but the updater says its the latest” is not actionable
   • Touch Display plugin 3.5.1 is a Volumio 3 version
   • Volumio 4 uses Touch Display 3.6.0
   • Run this via SSH or check in UI: cat /etc/os-release
   • Report exact VERSION_ID value

2. Installation method potentially destructive

   • “raspberry image writer” - did you use Raspberry Pi Imager?
   • If yes: did you apply ANY OS customization settings (hostname, SSH, WiFi, user/password)?
   • Raspberry Pi Imager customization creates a firstrun.sh script designed for Raspberry Pi OS
   • Volumio has its own first boot sequence - applying customization WILL break it
   • Correct procedure: Flash with NO customization whatsoever, configure via Volumio wizard only

3. Display model unknown

   • “new 7 inch display” is insufficient
   • Is it: Official RPi 7" DSI (v1), Official RPi 7" DSI v2 (1280x720), HDMI display, other?
   • Provide exact manufacturer and model number

4. Raspberry Pi4 model unknown

   • Different Pi models require different KMS overlays
   • Identify your board: [GUIDE] Identifying Your Raspberry Pi Board on Volumio: A Comprehensive Guide to Revision Codes

5. Current userconfig.txt contents unknown

   • You said you “tried a few changes” - what is the current state?
   • Provide complete contents of /boot/userconfig.txt

6. Log link missing - MANDATORY

   • Generate log from http://volumio.local/dev (or http://[your-volumio-IP]/dev)
   • Paste the resulting URL here
   • No log = no help. Ever.

Provide:

• Exact Volumio version
• Exact Raspberry Pi model (revision code)
• Exact display model with manufacturer
• Complete /boot/userconfig.txt contents
• Step-by-step description of Raspberry Pi Imager usage (every option selected)
• Log link from /dev page

Kind Regards,

[Fredothegreat]

Hey @Fredothegreat,

Thank you for the detailed information - this makes diagnosis straightforward.

Problem:

Your Official Raspberry Pi Touch Display 2 is not working because the required device tree overlay is missing. The log confirms the system is using legacy HDMI framebuffer (bcm2708_fb at 640x480) instead of detecting your DSI display.

The Touch Display 2 (ili9881 controller, 1280x720) requires explicit overlay configuration - it does not auto-detect on Volumio.

Solution:

Edit /boot/userconfig.txt via SSH and add:

# Add your custom config.txt options to this file, which will be preserved during updates

# Official Raspberry Pi Touch Display 2 (1280x720)
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-ili9881-7inch

Save the file and reboot.

Explanation:

• vc4-kms-v3d: Required KMS video driver for X11/graphics stack (Touch Display plugin depends on this)
• vc4-kms-dsi-ili9881-7inch: Driver for the Touch Display 2 panel

Rotation (if needed):

If you need to rotate the display, append rotation parameter:

dtoverlay=vc4-kms-dsi-ili9881-7inch,rotation=180

Valid rotation values: 0, 90, 180, 270

Reference:

There is a dedicated community guide for this display:

Notes:

• Your installation method was correct - flashing with Pi Imager and skipping customization is the proper procedure
• Touch Display plugin 3.5.1 should work once the overlay is configured
• If touch input direction is wrong after display works, use invx, invy, or swapxy parameters on the overlay line

After making changes, generate a new log if problems persist.

Kind Regards,

[Fredothegreat]

Thats probably the best response to an IT problem I have had in years well done you
great info on the button and fixed the problem.
its now working.
orientation can be changed in the plugin so that also works.
only issue I have is the touch appears to be around 20mm off! i can drag my finger across the screen and with mouse enabled the icon is 20mm behind my finger
is there anyway of calibrating this? I did a search through the links you gave me but coulfnt find a mention of calibration

many thanks again

[nerd]

Hey @Fredothegreat,

Excellent news that the display is working.

The touch offset is likely caused by the Touch Display plugin having been installed and configured when the display was not properly initialised. The plugin captured incorrect parameters from the legacy framebuffer output.

Try first:

1. Uninstall the Touch Display plugin via the Volumio UI
2. Reboot
3. Reinstall the Touch Display plugin
4. Configure rotation within the plugin settings
5. Test touch accuracy

This clean reinstall with the correct dtoverlay active should resolve the 20mm offset.

If not:

Should the touch offset remain after the reinstall procedure, please report the issue in the Touch Display plugin thread:

[PLUGIN] Touch Display

I have rewritten and extended the touch display plugin. The following features have been added to the plugin’s configuration page: Screen saver The options allow setting the timeout in seconds until the screen saver (DPMS state “off”) gets invoked. A value of 0 disables the screen saver. Further more it is possible to block the screen saver as long as Volumio is in playing state.

Thats great thanks i will give it a go
Project nearly finished!

[Fredothegreat]

OK this is now officially weird

trying to resolve the alignment I did a fresh install of Volumio using the same process as before
but now when I go to the plugins its showing the touch screen plugin as 3.6 I read above that 3.6 was for v4?
also it fails install just cant find the correct repository.

@nerd just to let you know I fixed (after @aluisperezh help) the touch alignment issue by adding ,nohdmi to the end of the dtoverlay=vc4-kms-v3d
so the userconfig now shows

Official Raspberry Pi Touch Display 2 (1280x720)

dtoverlay=vc4-kms-v3d,nohdmi
dtoverlay=vc4-kms-dsi-ili9881-7inch

aligment fixed
many thanks for your time

Hello.

I don’t think the problem has been fully resolved (at least for me). The screen displays and rotates, but the touchscreen doesn’t. When I adjust the rotation angle in the system settings, only the screen rotates, and the touchscreen remains in its original setting.

Has anyone managed to solve this problem?

[Wheaten]

Hi @sheliak

Welcome.

Yes, almost everyone solved it.
The difference? They left behind actual information instead of a mysterious riddle carved into a cave wall.

Things like, I know it’s just crazy, but give it a try:

• Which hardware you’re using (not “a Pi‑ish thing with vibes”)
• A direct link to your screen (telepathy still in beta)
• Which version of Volumio — and please, for the love of debugging, don’t say “latest”. That’s what everyone says right before chaos begins.

[sheliak]

I’m sorry, but I’m just learning about Volumio and hi-fi music. I’m replying now. I’m using a Raspberry Pi 4 + Hifiberry Digi2+ + Topping E30II, plus a Raspberry Pi Touch Display 2. I’m just building my setup and have installed the latest version of Volumio from their website (Volumio-4.073-2025-12-05-pi).

[nerd]

Hey @sheliak,

Welcome to Volumio.

The symptom you describe - screen rotates but touch does not follow - indicates you are using system settings or the Touch Display plugin UI to rotate the display. This method only rotates the framebuffer via xrandr. The touch input matrix is not updated.

To rotate both display AND touch together, the rotation must be applied via the dtoverlay parameter directly.

Before I can provide the correct configuration, please confirm:

1. Is your Touch Display 2 the 5" or 7" version?
2. Please provide log link from http://volumio.local/dev
3. Current contents of /boot/userconfig.txt

The overlay name differs between sizes, so this detail is required.

HI

I have just updated my previous version to Version 4.119. It is working perfectly regarding the music, but the PI 7" official RPI screen no longer displays the “Now Playing Screen”.

When booting, RPI displays the logo of volumio, then screen stays black. I can connect to volumio and play music by using my phone to select track.

I went in the PI screen setup and change the configuration display from HDMI to DSI I or O,
“DSI: Raspberry Pi Touch Display 7” (Original), KMS CMA: 64MB"
then reboot.
Same result the screen is black and the configuration summary stays to
“HDMI0: Auto Detect (EDID), KMS CMA: 64MB”

It sounds that RPI does not take in account the change I did.

Attached two screen copy that hope would help.

Can you help me ?

Hey @gvida,

To investigate this we need two things from you.

First, a log link captured while the issue is reproducing. Steps:

1. Open Pi Screen Setup, select DSI: Raspberry Pi Touch Display 7" (Original) and apply
2. Reboot
3. With the screen still black, open the web UI from your phone (192.168.0.179 in your case) and navigate to http://192.168.0.179/dev
4. Use the Send button under the Log section
5. Paste the resulting URL here

Do not reboot again before posting the link.

Second, the contents of /boot/videoconfig.txt and /boot/config.txt. SSH in and paste the output of:

cat /boot/videoconfig.txt
cat /boot/config.txt

Without these the report cannot be advanced.

One note: the “Failed to stop volumio-kiosk.service” error in your screenshot is emitted by the Touch Display plugin, not by Pi Screen Setup. The two plugins are separate.

Kind Regards,

[gvida]

Ok so this explains why screen is black? What next step to do ?

[nerd]

Hey @gvida,

Two things confirmed from what you posted:

1. /boot/videoconfig.txt is correctly generated by Pi Screen Setup for the original 7" Touch Display on a Pi 4.

2. /boot/config.txt correctly includes /boot/videoconfig.txt.

From the boot log:

• The kernel is running on the legacy bcm2708 firmware framebuffer at 800x480
• vc4-drm (the KMS driver) does not bind, so no /dev/dri/card0 is created
• The Touch Display plugin shows status FAILED in plugins.json, and no Xorg or Chromium processes are running

That is the chain producing the black screen: KMS is not active, so X cannot start, so Touch Display has nothing to render to.

What is missing is /boot/volumioconfig.txt. SSH in and paste:

cat /boot/volumioconfig.txt

Also, on the Pi Screen Setup plugin page, scroll to the bottom and check whether there is any “OTA drift detected” warning section. If yes, post a screenshot.

Kind Regards,

[gvida]

HI

1-There is no ““OTA drift detected” warning section.” at the bottom of the screen
2-Here is the volumioconfig.txt file as it is
