Linux/BEAGLEBK: Segmentation fault when HDMI is removed

Samer Abbas
Expert 1055 points

Part Number: BEAGLEBK

Tool/software: Linux

Hi,

I am using Sitara linux SDK for beaglebone black, where I am running a program on HDMI display. At the HDMI output I am using TS3DV642 as a HDMI splitter. So whenever a button is pressed the display switches between another HDMI source. As long as the display is on Beaglebone HDMI output it would work fine, but as soon as the display switches to another HDMI source, I get an error on Linux saying: The Wayland connection broke. Did the Wayland compositor die?


And when I try to run my program again then I get this error, because the HDMI was switched to another source.
"Failed to create display (No such file or directory)"

Or sometimes I get this error:

"Segmentation fault (core dumped)" and the program stops running. 

How can I keep my program running even when HDMI source is changed?

Thank you,

    Hi Margarita,

    The above log is from when I received "The Wayland connection broke" error.

    After this now I switched the HDMI source back to Beagle, but it kept showing "Please wait..." on HDMI, so I started weston by using this command: /etc/init.d/weston start
    Weston launched and I was able to run my program, but when I switched the HDMI source again then I saw "Segmentation fault (core dumped)" error and my program shutdown. I am also trying to control switching of HDMI from my running program, but whenever HDMI is switched, my program shuts off and then I have to manually switch HDMI source instead of getting input from my program. All I want is for Weston to keep running even when HDMI source is switched to another source. Weston just sees that HDMI is not present and shuts itself off, hence closing my program.

    Following is the log for this error:

    The limitation comes from weston compositor. This is not supported use case for us.

    Is there anyway Weston can be modified to keep the program running even when there is no HDMI display?

    Weston software is in public domain -  

    For PLSDK 4.x: we are using weston 1.11.

    If you are using Yocto build, then the software code link and TI patches are available at yocto  (meta-arago/meta-agaro-distro/recipes-graphics/wayland and oe-core/meta/recipe-graphics/wayland)

    Thanks for quick reply Manisha, but I have no Idea how to do it. I am new to linux, and would really appreciate if anyone can help me with this. I just want Weston to launch without HDMI display and keep the program running even when there is no display.
