我计划运行一个电子我的 UDOO Neo i.MX6 开发板上的应用程序UDOO Neo 官方 st1232 7 英寸触摸屏套件。我创建了一个自定义 Linux 发行版狭隘（重击分支）能够构建“准备启动”映像。我启用了“x11-base”图像功能来拥有所有 Xorg 软件包，并且我有元飞思卡尔提供补丁的层，以便拥有与硬件完全兼容的发行版（Vivante）。但是，在启动过程结束时，我收到一条来自 的 seg failure 错误消息xinit。
这是我的/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 meta-freescale 层添加的，并且我手动附加了 st1232 触摸屏 InputClass。
文件的输出/var/log/Xorg.0.log：

我的 Xorg 配置正确吗？为了使 Xorg 正常工作，什么是重要的？我听说过export DISPLAY=:0很多，但运行它并不能解决我的问题。
答案1
您必须下载vivante 5.0.11驱动程序版本，因为6.2是针对DRM的，不支持imx6。可以看看参考： https://lists.yoctoproject.org/g/meta-freescale/topic/68840298#24216 https://community.nxp.com/thread/526149
答案2
我只是添加了这个补丁到我的图层，现在它可以工作了。
