【MYS-6ULX-IoT试用体验】yocto x11vnc远程桌面

`最近试着搞搞远程桌面，需要配置conf文件。
  1. # i.MX DISTRO for X11 with no wayland

  3. include conf/distro/include/myir-imx-base.inc
  4. include conf/distro/include/myir-imx-preferred-env.inc

  6. DISTRO = "myir-imx-x11"

  8. # Remove conflicting backends.
  9. DISTRO_FEATURES_remove = "wayland"

  11. # These are X11 specific
  12. DISTRO_FEATURES_append = " x11"
复制代码
保存为myir-imx-x11.conf 存放在sourcesmeta-myir-imx6ulxconfdistro文件夹下。
然后
DISTRO=myir-imx-x11 MACHINE=mys6ull14x14 source fsl-setup-release.sh  

接下来修改local.conf文件
  1. MACHINE ??= 'mys6ull14x14'
  2. DISTRO ?= 'myir-imx-x11'
  3. PACKAGE_CLASSES ?= "package_rpm"
  4. EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
  5. USER_CLASSES ?= "buildstats image-mklibs"
  6. PATCHRESOLVE = "noop"
  7. BB_DISKMON_DIRS = "
  8.     STOPTASKS,${TMPDIR},1G,100K
  9.     STOPTASKS,${DL_DIR},1G,100K
  10.     STOPTASKS,${SSTATE_DIR},1G,100K
  11.     STOPTASKS,/tmp,100M,100K
  12.     ABORT,${TMPDIR},100M,1K
  13.     ABORT,${DL_DIR},100M,1K
  14.     ABORT,${SSTATE_DIR},100M,1K
  15.     ABORT,/tmp,10M,1K"
  16. PACKAGECONFIG_append_pn-qemu-native = " sdl"
  17. PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"
  18. CONF_VERSION = "1"

  20. DL_DIR ?= "${BSPDIR}/downloads/"
  21. ACCEPT_FSL_EULA = "1"

  23. CORE_IMAGE_EXTRA_INSTALL += "openssh
  24.                                                         x11vnc"
复制代码
添加x11vnc。
截下来要添加一个补丁文件“remove-redundant-RPATH.patch”。

然后存放在sourcesmeta-openembeddedmeta-oe
ecipes-graphicsx11vncfiles
修改x11vnc_0.9.13.bb文件
  1. SUMMARY = "Exports your X session on-the-fly via VNC"

  22. REQUIRED_DISTRO_FEATURES = "x11"

  24. PACKAGECONFIG ??= "${@bb.utils.contains('DISTRO_FEATURES', 'zeroconf', 'avahi', '', d)} libvncserver"

复制代码
修改如下：
SRC_URI = "${SOURCEFORGE_MIRROR}/libvncserver/x11vnc/${PV}/x11vnc-${PV}.tar.gz
file://starting-fix.patch
file://endian-fix.patch
file://remove-redundant-RPATH.patch "
添加：file://remove-redundant-RPATH.patch
接下来就可以正常编译了！！
最后说说如何启动vnc
设置密码：x11vnc -storepasswd
启动：x11vnc -display :0 -auth /var/run/lightdm/root/:0 -forever -bg -o /var/log/x11vnc.log -rfbauth .vnc/passwd -rfbport 5900
启动.vnc/passwd是设置密码时生成的文件。
最后附上效果图：
