6 years ago So your problem is X not using /dev/fb8, but it's using some other display? You can start by looking in /var/log/Xorg.0.log. This isn't fbtft specific, so I suggest you seek help elsewhere. I know very little about the userspace side of graphics.

6 years ago I did explain what I did more specifically here: https://forum.armbian.com/topic/5561-how-to-configure-scriptbincustomfex-for-spi-lcd/
If you have time take a look it, maybe gives some idea to solve problem...

I found this tutorial in armbian documentation, but as I know my LCD uses "fb8" framebuffer. So I am not sure how can I configure this settings? maybe it runs after this changes?
script.bin/fex file
The settings in the [disp_init] section of the script.bin/fex file define the display output enabled at boot.
An example configuration for HDMI:
[disp_init]
disp_init_enable = 1
disp_mode = 0
screen0_output_type = 3
screen0_output_mode = 4
fb0_framebuffer_num = 2
fb0_format = 10
fb0_pixel_sequence = 0
fb0_scaler_mode_enable = 0
disp_mode selects single-screen output or different dual screen modes. Generally this is 0, which means use screen0 with fb0 (one screen).
screen0_output_type = 3 means HDMI output.
screen0_output_mode selects the video/monitor mode to use (resolution and refresh rate). See the table in the Fex guide.
fb0_framebuffer_num selects the number of buffers for fb0, generally you need 2 or more for video acceleration or Mali (3D), 3 is better.
fb0_format and fb0_pixel_sequence determine the pixel format in the framebuffer. The above example (values of 10 and 0) selects the most common variant of 32bpp truecolor (ARGB).
fb0_scaler_mode_enable selects whether the scaler should be enabled. Enabling it does not really scale pixels, it configures the scaler to scale pixels 1-to-1 which can fix screen refresh-related problems at 1080p resolution. See the section below.
Similar parameter are defined for screen1 (which is usually disabled in practice).

Hi I have an 2.2" ili9341 LCD, nanopi-m1 board, armbian 5.30(ubuntu server 16.04), and I can make it work by this commands manually:
But when I try to make it permanent:
It doesn't work after reboot (I have a blank black screen that looks like when I run "sudo modprobe fbtft_device custom name=fb_ili9341 gpios=reset:1,dc:201,led:6 speed=16000000 rotate=90 bgr=1" , I mean LCD is on but blank screen). But when I run this command manually :
FRAMEBUFFER=/dev/fb8 startxit works again!
