It isn't clear to me what the hardware configuration is and how you are expecting Touch UI to work.

I have the TouchUI plugin installed on my OctoPi / OctoPrint system so that I can use OctoPrint's web interface on my small screen devices like my cell phone and a small tablet. TouchUI converts the normal web pages into pages that are more useable on those small screens.

You have a small screen but it is attached directly to the RPi. Have you followed the instructions in the TouchUI wiki (in particular, this setup)?

We will be able to provide better help if you give us step by step details on what you have done and what the output is (especially for steps that fail).

my touch UI not load...just a blackscreen with a underline _ not start the touch UI

Did you follow the steps posted at https://github.com/BillyBlaze/OctoPrint-TouchUI/wiki/Setup:-Troubleshooting#boots-to-blackscreen?

Hello, The instructions talk about sudo nano /usr/share/X11/xorg.conf.d/99-fbdev.conf and not /etc/X11/xorg.conf.d/99-fbdev.conf"

8

/usr/share/X11/xorg.conf.d/99-fbdev.conf open the file
Section "Device"
Identifier "touchscreen"
Driver "fbdev"

and is the same that billy said at tutorial that you talk

9

you have some email? facebook whatssapp to send photos for you understand?

10

What part of:

Run sudo nano /etc/X11/xorg.conf.d/99-fbdev.conf
if file/path does not exist then create it

don't you understand?

11

so when billy said other thing in 2017?

Hello, The instructions talk about sudo nano /usr/share/X11/xorg.conf.d/99-fbdev.conf and not /etc/X11/xorg.conf.d/99-fbdev.conf

NOT ETC/X11

12

I'm sorry but without the actual hardware, I have exhausted my abilities to help.

13

what hardware my dear? not fisical problem is logic....TOUCH UI BLACK SCREEN when start

14 
sudo touch /etc/X11/xorg.conf.d/99-fbdev.conf
sudo nano /etc/X11/xorg.conf.d/99-fbdev.conf
16

touch: cannot touch '/etc/X11/xorg.conf.d/99-fbdev.conf': No such file or directory

17

If the /etc/X11/xorg.conf.d folder doesn't exist then this makes me think that the Desktop (PIXEL) GUI system isn't installed.

  • The TouchUI plugin won't install the Desktop/GUI/PIXEL/X windows system on the Raspberry Pi, by the way
  • The standard OctoPi image is Raspbian Stretch Lite, meaning that it doesn't have the Desktop.
  • It does, though, include a script for installing the Desktop and it lives in ~/scripts. If you wanted to install the Desktop, you would run this script.

If you read this post, I'm describing in general what I had to do to get this to work. It is not a step-by-step tutorial.
