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

Thanks for the quick reply. That is the procedure I used. I ran the script you suggested. The Touch Display plugin does not report any error but the screen is still blank. Same error on both RPIs. Here is the log again:

Please post the output of

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

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.

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

configuration options for tuning the driver.

Execute

sudo sed 's/fb0/fb1/' -i /usr/share/X11/xorg.conf.d/99-fbturbo.conf

Then restart the plugin or reboot.

Thank You. That fixed the problem. The screen is now working. It looks nice after settting the scale factor to 60%


.I also tested with a RPI 4 and it works.
For those encountering the same problem after following Page 1 to install Volumio. These are the two steps provided by gvolt that may fix your problem:

  1. sudo apt-get -y install xserver-xorg-video-fbturbo
    Then restart the Touch Display plugin or reboot.
    2.sudo sed ‘s/fb0/fb1/’ -i /usr/share/X11/xorg.conf.d/99-fbturbo.conf
    Then reboot
    You may also want to change the scale factor in the Touch Display plugin to 60.
