<div dir="ltr"><div>Dear All, We are starting weston (1.9.0) using below systemd unit file of type notify (backported sd_notify related changes from weston 1.11.0 to weston 1.9.0). It works well with i.MX6 (NXP, fbdev backend) based platform, however with Jacinto (TI, drm backend) based platform sometimes it fails to start and sometime it works after reboot. It always works if we start weston service manually after platform boots up using “systemctl”. </div>Is there anyone encountered this issue? Any suggestion/inputs to fix this? <div> Weston.service file: [Unit] Description=weston (wayland compositor) DefaultDependencies=false After=pvrinit.service [Service] #Type=simple Type=notify NotifyAccess=all WatchdogSec=60s ExecStartPre=/bin/mkdir -p /var/run/root/1000 ExecStartPre=/bin/chmod 0700 /var/run/root/1000 ExecStart=/usr/bin/weston --tty=1 --idle-time=0 --backend=drm-backend.so --connector=36 --log=/tmp/weston.log # --- Exec options --- Environment=XDG_RUNTIME_DIR=/var/run/root/1000 EnvironmentFile=-/tmp/GlobalSystemSettingsEnvironment EnvironmentFile=-/tmp/GlobalSPOTOverrideEnvironment # EOF Below is the status of service when fails and when starts successfully.
