 Posted: Tue Jan 18, 2022 1:36 pm Post subject: Chromium webrtc wayland screencasting erroring |
 |
|
Trying to screen share from chromium on wayland. I'm using sway as my window manager and I have a AMD video card.
When I screen share and select a screen I get:
| Code: |
MESA-LOADER: failed to open vgem: /usr/lib64/dri/vgem_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib64/dri, suffix _dri)
failed to load driver: vgem

This was solved by enabling wireplumber as stated in the wiki. https://wiki.gentoo.org/wiki/PipeWire
This error,
| Code: |
MESA-LOADER: failed to open vgem: /usr/lib64/dri/vgem_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib64/dri, suffix _dri)
|
is solved by setting
| Code: |
MESA_LOADER_DRIVER_OVERRIDE=radeonsi
|
seems to just be appending _dri.so and trying to load from /usr/lib64/dri.
The | Code: | | ERROR:egl_dmabuf.cc(544)] Failed to query DMA-BUF modifiers. |
error still exists but is not affecting screen casting. |
