This vfd.conf should work for you.

# This file must be renamed to vfd.conf and placed in the /storage/.config/ folder.
#
# A95X R2/ABOX A1 max/ANTSIR D6/DOLAMEE D6 - S905W/S905X configuration
# This vfd.conf requires the matching a95x_r2 dtb file.

Reboot the box. SSH into it, run the following commands:
dmesg | paste
systemctl status openvfd | paste
Then the post the links here.

Sorry, I forgot that you also need to replace the DTB file.
Use this one: gxl_p281_2g_a95xr2.dtb or gxl_p281_1g_a95xr2.dtb if it’s a 1GB ram box
You can run the following commands:

mount -o remount,rw /flash
cp /usr/share/bootloader/device_trees/gxl_p281_2g_a95xr2.dtb /flash/dtb.img
reboot

@TheCoolest Thanks for the help on the display for the a95x_F1. always very attentive.

Good @TheCoolest , that vfd.conf could use the D7 dolamee? Then, I leave the dtb of android.

Greetings and sorry for disturbing.

TheCoolest · 10 June 2019 19:10

Sorry, but that DTB is no good.
You should try the A95X-R2 DTB + vfd.conf, I think it should work.

Thanks. The A95X-R2 DTB and vfd.conf should work with this device. You need to use that DTB, otherwise the VFD will not work.

SamWilson · 10 June 2019 20:23

Thanks, it works correctly

Hi All! I have X92 tvbox. Then boot android display show “booting” and then i suspend android display show “–/--” symbols. And i always known that tvbox is in susspend mode.
It is possible realize with openvfd? Well, at least suspend indication.

TheCoolest · 14 June 2019 18:36

What do you see when you suspend the box?

dimania · 15 June 2019 16:10

I have a freind of mine’s MXQ G10SX box which is now running fine from a CoreELEC KODI 18 bootable SD card. BUT I cannot find a suitable VFD.CONF file in the list. I was a bit suprised as these MXQ boxes are very popular I understand. Have no problem with the display on my Tanix TX9 Pro box as that worked straight away with CoreELEC with a VFD.CONF file whcih I had used with LibreELEC 8.2.x.x.

The display is blank and the Open VFD service is running and enabled but clearly I need a vfd.conf file. So can you kindly advise me which vfd.conf file I need for this box as there are way too many to randomly test all of them.

I worked with you last year The Coolest to get my then new model TX9 Pro box display working with LibreELEC 8.2 and we of course succeeded thanks to your great help and some testing here too. I remember you corrected an upside down display with that box which otrherwise used the same display as the similar Zoork box.

TheCoolest · 24 June 2019 05:56

If none of the vfd.conf files on the GitHub repo work, I’ll need to see the original Android DTB to try and extract the configuration data from it (it’s not always there, but most of the time it is).

RayW · 24 June 2019 06:07

Meant to say Vorke box not Zoork duh.

Jus tnoticed that the G9SX box has an identical lookign case and display so now trying to download that vfd file. But cannot download the actuial file only the text whcih I will copy and past to a new file called vfd.conf and try that, I am maybe missing something as surely I should be able to download the actual required vfd.conf file I need without copy and pasting the text to a newly made file here ???

Thanks mate for the very fast reply.

RayW · 24 June 2019 06:34

No still nothing trying the g9SX VFD.CONF file and yet the MXQ G9SX looks identical case and front panel to the MXQ G10SX ??? I thought I woulod get somethjing on the display. Could it be the wrong DTB file ?? Though I doubt that as everything else works fine on this G10SX box using a 2GB DTB file the same as I use on the Tanix TX7 and Beelink MXIII II boxes.
