Hi
I can’t get the display to work with Volumio ( ver. 3.631 ) on Rpi5. It work perfectly with Rpi OS but with Volumio it doesn’t even light up.
I’ve tried adding dtoverlay to config.txt but nothing happens it’s dead as a dodo. Only plugins installed are Touch Display and Now Playing. Am I missing something?
Thanks.
@gvolt can you help with this?
What did you add?
dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch,dsi0
Can you confirm that the display is connected via a display and not via a camera DSI cable?
Does the display work if connected to DSI1? In that case dtoverlay=vc4-kms-dsi-7inch,dsi0 needs to be changed to dtoverlay=vc4-kms-dsi-7inch.
If possible post pictures of the DSI cable connections made to display and Pi.
Hi @gvolt
I’m terribly sorry for this late reply and I apologise for this (had some family issues).
I’ve checked connections again, did complete reinstall, added dtoverlays to userconfig and now everything works (I’ve definitely messed something up last time).
But I now have another problem sort of (sorry).
Currently I’m trying nvme boot and I can’t get touch plugin to work with volumio ver. 3.639 (I know it’s alpha) booting from nvme drive.
The screen works fine until volumio boots than it goes blank (no picture and no backlight) if I disable the plugin I get the usual screen (Welcom to volumio, WebUI available etc.).
I’ve made a log, hope this can help: http://logs.volumio.org/volumio/mSFYB8l.html
From the system running Volumio 3.639 post the output of
cat /boot/config.txt
and
cat /boot/userconfig.txt
Which DSI port is the display connected to?
config.txt :
initramfs volumio.initrd
gpu_mem=128
gpu_mem_256=32
gpu_mem_512=32
gpu_mem_1024=128
max_usb_current=1
[pi5]
usb_max_current_enable=1
[all]
include volumioconfig.txt
include userconfig.txt
userconfig.txt:
dtoverlay=vc4-kms-v3d-pi5
dtoverlay=vc4-kms-dsi-7inch, dsi0
dtparam=nvme
dtparam=pciex1_gen2
Display is connected to DSI port 0.
I don’t expect that to be the solution, but please try removing
dtoverlay=vc4-kms-v3d-pi5
from “/boot/userconfig.txt”.
Is the DSI cable a display (or camera) cable?
Did you try connecting the display to DSI1?
I’ve tried everything you suggested but still not working.
Display is working on RpiOS on DSI 0 and DSI 1 ports without a problem ( cable is display cable not camera cable ).
On Volumio ( v.3.639 ) it’s “working” ( when the plugin is inactive ) only on DSI 0 on DSI1 it doesn’t even start ( I’ve removed dsi0 from dtoverlay ).
The attached picture is display when booting volumio and the second one is when volumio completes its boot ( plugin inactive otherwise display is dead ).
Is that on an Odroid device?
The error messages “Unknown operand” have no meaning. It is an init script deficiency, which has been corrected in the soon the be released startup overhaul.
Please post the output of
lsmod
and
cat /etc/X11/xorg.conf.d/99-vc4.conf

Stop the Touch Display plugin and change the content of “/etc/X11/xorg.conf.d/99-vc4.conf” to
Section "OutputClass"
Identifier "rp1"
MatchDriver "rp1-vec|rp1-dsi|rp1-dpi"
Driver "modesetting"
Option "PrimaryGPU" "true"
EndSection
Then start the Touch Display plugin.
That did it!! 
I’m truly grateful for your amazing help.
Thank you very much. 
Hm, the correct settings in “99-vc4.conf” should be applied automatically by the Touch Display plugin…
Has this been a fresh Volumio installation?
What version of the Touch Display plugin did you install?
Yeah, fresh install.
I used guide from: https://community.volumio.com/t/beta-raspberry-pi-boot-from-usb-nvme/65699
The plugin is version 3.4 (stable).
As I said before this happens only on this version of volumio ( 3.639 RC-Testing ), on the official release (3.631) the plugin worked flawlessly.
Thank you once more.
Ok, could you please PM me the output of
cat /proc/modules
from both 3.631 and 3.639?
From the 3.639 system also post the result of
cat /etc/os-release
