Hi Xu May I ask which source code you used? The simple-egl inside weston source doesn't not using windowmanager, or homescreen. Can not display it's surface. The config.xml inside wgt contains appid and version, If you want change simple-egl to poi, you should change config.xml also. Not just rename wgt file. Here is a sample using simple-egl with homescreen, windowmanager. You can try this one. https://gerrit.automotivelinux.org/gerrit/gitweb?p=src/libhomescreen.git;a=tree;f=sample/simple-egl;h=400f8e464bfc0ad67a4d98e95a0e26b2142aeb92;hb=refs/heads/master BR, Zheng On 2019/03/11 18:23, Clive Xu (Arm Technology China) wrote: > Hello AGL, > > I’m trying to run /usr/bin/weston-simple-egl on shell, the app loaded > the right libraries and didn’t crashed, but nothing displayed on the > homescreen: > > I also tried the wgt file in [1], it still doesn’t working, my steps are > as following: > > -rename weston-simple-egl.wgt to poi.wgt > > -copy poi.wgt to /usr/AGL/apps/autoinstall/ and replace the original one > > -reboot > > -1 . click the **POI** icon on the LAUNCHER but nothing displayed, > **afm-util ps** shows that the poi@0.1 <mailto:poi@0.1> is not running. > > -2. afm-util run poi@0.1 <mailto:poi@0.1> will generate a runid, but it > should be crashed soon > > Could you please give me some suggestions? > > [1] > https://lists.linuxfoundation.org/pipermail/automotive-discussions/2017-April/003816.html > > Thanks & Brs, > > Clive > > IMPORTANT NOTICE: The contents of this email and any attachments are > confidential and may also be privileged.
