X11
如何為帶觸摸屏的嵌入式 i.MX6 板配置 X11？
我計劃使用適用於 UDOO Neo 的官方 st1232 7’’ 觸摸屏套件在我的 UDOO Neo i.MX6 板上執行Electron應用程序。我使用Poky （thud 分支）創建了一個自定義 Linux 發行版，以便能夠建構“準備啟動”映像。我啟用了“x11-base”圖像功能以擁有所有 Xorg 包，並且我擁有提供更新檔的元飛思卡爾層，以便擁有與硬體 (Vivante) 完全兼容的發行版。但是，在引導過程結束時，我從.
xinit這是我的
/etc/X11/xorg.conf文件：Section "Device" Identifier "i.MX Accelerated Framebuffer Device" Driver "vivante" Option "fbdev" "/dev/fb0" Option "vivante_fbdev" "/dev/fb0" Option "HWcursor" "false" Option "DisplayEngine" "pxp" EndSection Section "ServerFlags" Option "BlankTime" "0" Option "StandbyTime" "0" Option "SuspendTime" "0" Option "OffTime" "0" EndSection Section "InputClass" Identifier "Touchscreen" MatchProduct "st1232-touchscreen" Driver "evdev" Option "Calibration" "3 794 476 0" EndSection它是由元飛思卡爾層添加的，我手動添加了 st1232 觸摸屏 InputClass。
