Weston desktop issues

Autonomous Machines Jetson & Embedded Systems Jetson Xavier NX

Hi, everyone,
I used Weston desktop on jetson xavier nx, and launch Weston using the following command

sudo weston-lanch -u `user’s name’

And i add xwayland=true at weston.ini in the core section.

After, the Weston launch normally, but when i run a Qt simple program,
it shows

libEGL warning: MESA-LOADER: failed to open tegra-udrm: /usr/lib/dri/tegra-udrm_dri.so: cannot open shared object file: No such file or directory

And the terminal log is shows

src/tegra_gbm.c:98: GBM-DRV error (tegra_gbm_bo_create): DRM_IOCTL_TEGRA_GEM_CREATE failed (size=131072)

src/tegra_gbm.c:98: GBM-DRV error (tegra_gbm_bo_create): DRM_IOCTL_TEGRA_GEM_CREATE failed (size=131072)

So where is file tegra-udrm_dri.so

Thanks

Hi,
Would like to know which Jetpack release you are using. Do you use 4.6.4 or 5.1.2?

Hi,
We have the section for running Weston:
Weston (Wayland) — Jetson Linux Developer Guide documentation

Please check and make sure you have followed the steps. We would expect it works fine by executing the steps one by one.

Hi @DaneLLL,
I want to run an X app at Weston and followed the steps, i used weston-launch as a non-root user, and modified weston.ini, added xwayland=true, but i could not find the shared object, i think it was compile option not enabled.

So i compile the complete Weston-9 for my NX, and when i used launch weston-launch, it shows

weston-launch must be run from a virtual terminal

So i could only use

Finally, the Weston desktop launched successfully and ran gnome-* normally, but when i ran my Qt program, it shows

Hi,
Could you apply the environment described in developer guide to your use-case? This is a tested setup and it would be great if you can develop your use-case based on it. It is possible other use-cases may not work properly.

Hi @DaneLLL,
If i apply the environment described in the developer guide to my use-case, it can not work, because my app needs X service but it has not found xwayland.so
