Hi torus1000,

Which application are you trying to run?, apparently some driver are not loaded correctly.

Dear Bio

Thank you for reply.

We tried Qt applications on x11 on Linux OS (L3.10.53).
Qt applications were created by QtCleator5.2.

Here is our segmentation fault reproduce procedure:

1 Add HID Multitouch panels driver in kernel config menu and build images as following.

  $ MACHINE=imx6qsabresd source fsl-setup-release.sh -b build-x11 -e x11

2 Write images to the SD card.

3 Bootup from SD slot then start X11.

4 Run Qt application.

5 Touch the panel quickly many times.

6 Memory size of Xorg server increase.

7 Segmentation fault occur. Screen freeze into white.

If we use mouse instead of multitouch screen, segmentation fault was never happen.

If exclude xinput2 lib from Qt runtime lib v5.2, segmentation fault was never happen neither.
However 3D drawing corruped.

(Q) Is there anyway to avoid segmentation fault and keep normal 3D drawing?

Regards,
