Waveshare 3.5inch LCD RPI (B) rev2.0 on RPI3B+ for Volumio

advr61 · May 14, 2021, 6:21pm

I did everything you asked
I reboot after touch /boot/resize-volumio-datapart
re-installed touchscreen plug in
watched the journal and saw many things but no errors.
re-installed chromium but got the message that chromium was already latest version so that is ok.

maybe to start all over again with a fresh image…

Yes, I would recommend that, too. It’s probably easier and faster than trying on a system which might be borked somehow by the previous attempts to get the screen working.

advr61 · May 14, 2021, 6:54pm

in the Xorg.0.log I saw:

Fatal server error:
[ 42.416] (EE) no screens found(EE)
w
*

Will restart tomorrow.
Thanks for all your help, at least I get some data at the screen

gvolt · May 14, 2021, 7:02pm

Please post or PM me the complete Xorg log.

advr61 · May 14, 2021, 7:04pm

Xorg.0.log.zip (2.0 KB)

no problem.

gvolt · May 14, 2021, 7:13pm

Problem is probably in “/usr/share/X11/xorg.conf.d/99-fbturbo.conf”. Please post the output of

cat /usr/share/X11/xorg.conf.d/99-fbturbo.conf

P.S. Did you run the script “ws-35b-v2.sh” on your fresh Volumio?

advr61 · May 14, 2021, 7:17pm

Yes, I did run your script after installing the touch screen plugin.

volumio@volumio:~$ cat /usr/share/X11/xorg.conf.d/99-fbturbo.conf

This is a minimal sample config file, which can be copied to

/etc/X11/xorg.conf in order to make the Xorg server pick up

and load xf86-video-fbturbo driver installed in the system.

When troubleshooting, check /var/log/Xorg.0.log for the debugging

output and error messages.

#The driver is made by Waveshare&Spotpear

Run “man fbturbo” to get additional information about the extra

configuration options for tuning the driver.

Section “Device”
Identifier “Allwinner A10/A13 FBDEV”
Driver “fbturbo”
Option “fbdev” “/dev/fb1”

    Option          "SwapbuffersWait" "true"

EndSection

I did not write the script. Don’t use it. It doesn’t fit your screen…

In “/usr/share/X11/xorg.conf.d/99-fbturbo.conf” “/dev/fb1” has to be changed to “/dev/fb0”, so the file looks like

# This is a minimal sample config file, which can be copied to
# /etc/X11/xorg.conf in order to make the Xorg server pick up
# and load xf86-video-fbturbo driver installed in the system.
#
# When troubleshooting, check /var/log/Xorg.0.log for the debugging
# output and error messages.
#
# Run "man fbturbo" to get additional information about the extra
# configuration options for tuning the driver.

Section "Device"
        Identifier      "Allwinner A10/A13 FBDEV"
        Driver          "fbturbo"
        Option          "fbdev" "/dev/fb0"

        Option          "SwapbuffersWait" "true"
EndSection

Then restart the plugin.

Yezzzzxx!

No it’s need to be calibrated.
And I have to recatch what I have done in the past hour:rofl:

gvolt · May 14, 2021, 7:42pm

advr61 · May 14, 2021, 7:44pm

many many thanks, I learned a lot in the past hour.
I almost had thrown the touchscreen in a far away corner

nadirfly · May 30, 2021, 5:02pm

don’t run…

It’s a good idea if i install ws-35b-v2.sh???

gvolt · May 30, 2021, 5:49pm

What does that mean: Is the screen not working at all, i.e. not even displaying something? Or is (just) touch still not working?

I suppose: No, I would think, the overlay from there does not suit the MPI3508.

Please show the results of

ls -al /usr/share/X11/xorg.conf.d

and

ls -al /etc/X11/xorg.conf.d
