Boot to X Windows on PiTFT<\/strong><\/p>\n

To enable booting straight to X windows on the PiTFT follow the steps below. \u00a0First make sure a display configuration which would conflict is not<\/strong> present by executing in a terminal on the Pi:<\/p>\n

sudo mv <\/span>\/<\/span>usr<\/span>\/<\/span>share<\/span>\/<\/span>X11<\/span>\/<\/span>xorg<\/span>.<\/span>conf<\/span>.<\/span>d<\/span>\/<\/span>99<\/span>-<\/span>fbturbo<\/span>.<\/span>conf <\/span>~<\/span><\/pre>\n<\/div>\n
\n
Don’t worry if the command fails with an error that the file doesn’t exist. \u00a0This failure is normal and should happen on a good PiTFT install. \u00a0You can ignore it and move on.<\/p>\n
Next run the command below to open the nano text editor as root and create the file\u00a0\/usr\/share\/X11\/xorg.conf.d\/99-pitft.conf<\/strong>:<\/p>\n
sudo nano <\/span>\/<\/span>usr<\/span>\/<\/span>share<\/span>\/<\/span>X11<\/span>\/<\/span>xorg<\/span>.<\/span>conf<\/span>.<\/span>d<\/span>\/<\/span>99<\/span>-<\/span>pitft<\/span>.<\/span>conf<\/span><\/pre>\n<\/div>\n
\n
When the editor loads to a blank file, copy in the text below:<\/p>\n
Section<\/span> \"Device\"\r\n    Identifier<\/span> \"Adafruit PiTFT\"\r\n    Driver<\/span> \"fbdev\"\r\n    Option<\/span> \"fbdev\"<\/span> \"\/dev\/fb1\"\r\nEndSection<\/span><\/pre>\n<\/div>\n
\n
Then save the file by pressing Ctrl-O<\/strong> and then enter<\/strong>, and finally exit by pressing Ctrl-X<\/strong>.<\/p>\n
The step above will create a configuration file which tells X windows that it should use the PiTFT framebuffer (located at \/dev\/fb1) by default when it runs.<\/p>\n
At this point you can use the raspi-config tool to enable booting to desktop just like normal on the Pi. \u00a0Run the following command:<\/p>\n
sudo raspi<\/span>-<\/span>config<\/span><\/pre>\n<\/div>\n
\n
Then pick the Enable Boot to Desktop\/Scratch<\/strong> option and choose if you want to boot to the console, desktop, or scratch environment. \u00a0After exiting the tool and rebooting you should see the Pi load X windows on the PiTFT after (be patient it can take around 30 seconds to load).<\/p>\n
If you want to disable booting to X, just use the raspi-config command again to choose the console boot option.<\/p>\n<\/div>\n
