Do you have any other plugins installed? If so, which?
The next time the message “Error connecting to the xserver.” occurs, please connect to Volumio via SSH, execute
cat /var/log/Xorg.0.log
and post the result.
At the moment I suspect that files the Xserver needs to start get corrupted - this might happen on a reboot e.g. due to insufficient power supply. Reason could also be a faulty SD card so you may use a fresh card for the next installation of Volumio to rule that out.
I have these plugins:
FusionDSP 0.1.32
80s80s Radio 1.0.2
Spotify 2.0.3
Volumio Spotify Connect2 3.0.8
Youtube2 0.1.8
YouTube Cast Receiver 0.1.2

Just to confirm: Is the log from the situation where you receive the error message?
What is the brand and model name of your screen?
Yes, the screen is not working now. I will need to reinstall the plugin to get it back. The monitor is an Amazon Generic 15.6 Touchscreen. The brand appears to be USparkle. I’ll see if I can find a model number
How is the screen connected? HDMI?
Is it this one or do you have a link?
Please post the result of
cat /usr/share/X11/xorg.conf.d/99-fbturbo.conf
cat /boot/config.txt
and
cat /boot/userconfig.txt
Yes, HDMI.
Yes, that’s the one I have.
volumio@volumio1:~$ cat /usr/share/X11/xorg.conf.d/99-fbturbo.conf
cat: /usr/share/X11/xorg.conf.d/99-fbturbo.conf: No such file or directory
volumio@volumio1:~$ cat /boot/config.txt
initramfs volumio.initrd
gpu_mem=32
max_usb_current=1
dtparam=audio=on
audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1
force_eeprom_read=0
include userconfig.txt
volumio@volumio1:~$ cat /boot/userconfig.txt
display_lcd_rotate=1
display_hdmi_rotate=1
Ok, and what gives
ls -al /dev/fb*
volumio@volumio1:~$ ls -al /dev/fb*
ls: cannot access ‘/dev/fb*’: No such file or directory
That meets my expectation.
Please try if this helps:
Exrcute
sudo curl -L https://raw.githubusercontent.com/waveshare/LCD-show/master/usr/share/X11/xorg.conf.d/99-fbturbo.conf-HDMI -o /usr/share/X11/xorg.conf.d/99-fbturbo.conf
and
sudo sed 's/"fbturbo"/"fbdev"/' -i /usr/share/X11/xorg.conf.d/99-fbturbo.conf
Then reboot.
Same result - The display remains blank and I still get the xserver error.
Yes, “99-fbturbo.conf” should not be required for a screen connected via HDMI, but I wanted to make sure that the absence of the file is not the cause after all. I think you can delete it again:
sudo rm /usr/share/X11/xorg.conf.d/99-fbturbo.conf
What you could try next is adding
hdmi_group=2
hdmi_mode=87
hdmi_cvt 1920 1080 60 3
hdmi_drive=2
to “/boot/userconfig.txt” and reboot. But the fact that the screen previously worked without this setting does not necessarily suggest that this change will help…
You are correct, that didn’t help.
The expected framebuffer device “fb0” is not present in “/dev”. This is the reason for the error message. Currently I am running out of ideas why this happens after a reboot… For now I suggest to uninstall and re-install the plugin and if the screen should work, post the result of
cat /var/log/Xorg.0.log
again.
I have reinstalled the plugin and it worked for a while. At some point, I started the system without the monitor connected via HDMI and that broke the plugin, again requiring it to be reinstalled. Here is the log file while everything is working:

Was this also the constellation when the problem occurred at the earlier time?
What is your Pi model?
No, but the screen is slow to start up. I am starting to wonder if the screen is starting too late and that is resulting in a similar condition. I’ll do some more testing.
I have a Pi3 B+
Hm, “hdmi_force_hotplug=1” in “/boot/config.txt” should take care of that IMHO. This option should make the Pi recognize an HDMI monitor that has not already been connected on boot, but gets plugged in / powered later on.
Do you have another HDMI monitor you could use for testing?
Please, when post a log ,use ``` in the line above your past to make it readble. Thanks 
I have done some more testing and here’s what I found:
I use the touch monitor rotated to 90 degrees. It works fine initially, but after 2-3 power cycles of the PI and monitor, the monitor will fail to display the image and I will get the xserver error.
If I rotate the screen back to 0 degrees using the plugin settings, the monitor comes up as expected, but if I rotate back to 90, it will not work, even after complete reboots.
If I reboot with a standard monitor, it works with either orientation.
If I boot with the standard monitor at 90 degrees and then switch the cable to the touch monitor, it will work.
The touch monitor will not work from boot at 90 degrees until I remove and reinstall the plugin.
That’s weird.
