i run start seatd with openrc and can see the socket:
| Code: |
guyuming@localhost ~ $ ps -ef|grep seatd
root 2339 1 0 12:07 ? 00:00:00 supervise-daemon seatd --start --stdout /tmp/seatdstdout --stderr /tmp/seatdstderr seatd -- -g video -l debug
root 2340 2339 0 12:07 ? 00:00:00 seatd -g video -l debug
guyuming@localhost ~ $ ls -l /run/seatd.sock
srwxrwx--- 1 root video 0 4月17日 12:07 /run/seatd.sock
guyuming@localhost ~ $ cat /etc/group |grep -e video -e seat
video:x:27:root,guyuming
seat:x:202:guyuming

weston can start with the same script on the same machine inside x11, with x11 backend |

have you tried with /run/user/1000 ? <<< https://stackoverflow.com/questions/77394122/weston-not-running-from-terminal-no-drm-device-found
i'am not sure if weston also needs dbus entry before start, e.g. dbus-run-session weston.

Make sure seatd is started at boot runlevel.
I've made my own startwayland script, which works on my systems which use seatd too.
I can share it here, if you'd like. I need to clean it up a bit first.

I tried adding dbus-run-session before session, but it does not fix.
I noticed the "no drm device found" message, but i can see the device file in system:
| Code: | guyuming@localhost ~ $ ls -lt /dev/dri
总计 0
crw-rw---- 1 root video 226, 0 4月18日 06:10 card0
drwxr-xr-x 2 root root 80 4月18日 06:10 by-path
crw-rw-rw- 1 root render 226, 128 4月18日 06:10 renderD128

My script works for DWL, which is based on wlroots, if i simply change weston to dwl.
And for the XDG_RUNTIME_DIR value, which is used by wayland client to communicate with wayland server i think. Does it have any usage before the compositor start? The problem here is that the compositor failed to start. Anyway, weston can start with the same script using x11-backend.
I had tried changed weston to gdb weston in the script to debug. But the system always hang when it calls sendmsg syscall to seatd via the /run/seatd.sock |

There is an example in wlroots: wlroots/examples/tablet.c
I build the tablet example and run to find that i get the same error.
By reviewing my script to start DWL, i find that i had solved this issue before with my reply in:
https://github.com/swaywm/sway/issues/7240
And the WLR_DRM_DEVICES=/dev/dri/card0 environment variable setting solve the issue for tablet example too.
But this variable is defined by wlroots, i need to find a similar one used by weston. |

man weston-drm - in Options.
| Code: | --drm-device=cardN
Use the DRM device cardN for rendering and output instead of the default heuristics based on seat assignments and boot VGA status. For example, use card0. |
i hope this is it !
