Please describe your issue below:

Swaydm cannot run due to some libwlroots issues

Post a console log of your issue below:

sway: symbol lookup error: /lib/aarch64-linux-gnu/libwlroots.so.10: undefined symbol: gbm_bo_get_fd_for_plane

It seems that libwlroots.so.10 used API gbm_bo_get_fd_for_plane, as current gnome desktop is hardware accelerated with Mali GPU, and the gpu library seems not support gbm_bo_get_fd_for_plane API, so you got this error.

Thanks.
Any way to fix this?

Two ways to fix this issue:

  1. Remove Mali GPU libries and install sway, but in this way you will not have hardware accelerated desktop.
$ sudo dpkg -r linux-gpu-mali-wayland
$ sudo apt install --reinstall   libegl1  libgles2  libgles2-mesa  libegl1-mesa-dev  libgles2-mesa-dev  libglvnd-dev  libgles1   libwayland-dev  mesa-common-dev  libgl-dev  libegl-dev libgles-dev libgbm-dev  libgbm1  libwayland-egl1
$ sudo apt install sway
  1. Modify sway source code to remove unsupported APIs and rebuild debian package to install.

gbm_bo_get_fd_for_plane added in mesa 21.1.0 Mesa 21.1.0 Release Notes / 2021-05-05 — The Mesa 3D Graphics Library latest documentation

maybe have possibility rebuild mesa libs ?

No, I know mesa support this API, but our Mali GPU libraries doesn’t support it.

Thanks.
The first way works just fine.
I am not familiar with the concept “hardware accelerated desktop”.
Would you mind telling me so details about that?

With GPU accelerated, you will have more smooth desktop.
