这依赖于使用键盘的物理访问

我正在使用 Debian Bullseye。我想以 systemd 服务的用户身份运行 Weston。我需要默认的 drm 后端，因此我认为需要使用 weston-launch 作为 root 启动它。但是，我尝试了多种配置，但无法运行。目前我正在尝试使用 weston-launch，但出现以下错误：

以下是一些文档的快速链接，准确描述了您正在寻找的内容：https://wayland.pages.freedesktop.org/weston/toc/running-weston.html#running-weston-from-a-systemd-service

文档中的示例

这依赖于使用键盘的物理访问

Debian 系统使用/etc/systemd/user/dir 作为 systemd 用户单元。

/etc/systemd/user/weston.socket

[Unit]
Description=Weston, a Wayland compositor
Documentation=man:weston(1) man:weston.ini(5)
Documentation=https://wayland.freedesktop.org/

[Socket]
ListenStream=%t/wayland-0

/etc/systemd/user/weston.service

[Unit]
Description=Weston, a Wayland compositor, as a user service
Documentation=man:weston(1) man:weston.ini(5)
Documentation=https://wayland.freedesktop.org/

# Activate using a systemd socket
Requires=weston.socket
After=weston.socket

# Since we are part of the graphical session, make sure we are started before
Before=graphical-session.target

[Service]
Type=notify
TimeoutStartSec=60
WatchdogSec=20
# Defaults to journal
#StandardOutput=journal
StandardError=journal

# add a ~/.config/weston.ini and weston will pick-it up
ExecStart=/usr/bin/weston

[Install]
WantedBy=graphical-session.target

创建文件后，您想让 systemd 通过运行重新加载更改systemctl --user daemon-reload

如果没有在计算机上创建登录会话，您需要物理登录并启动运行的 westonsystemctl --user start weston

允许以普通用户身份通过​​ VT 或 SSH 登录

此方法需要将服务作为常规 systemd 系统单元运行。

/etc/systemd/system/mysession.service

[Unit]
Description=My graphical session

# Make sure we are started after logins are permitted.
After=systemd-user-sessions.service

# if you want you can make it part of the graphical session
#Before=graphical.target

# not necessary but just in case
#ConditionPathExists=/dev/tty7

[Service]
Type=simple
Environment=XDG_SESSION_TYPE=wayland
ExecStart=/usr/bin/systemctl --wait --user start mysession.target

# The user to run the session as. Pick one!
User=user
Group=user

# Set up a full user session for the user, required by Weston.
PAMName=login

# A virtual terminal is needed.
TTYPath=/dev/tty7
TTYReset=yes
TTYVHangup=yes
TTYVTDisallocate=yes

# Fail to start if not controlling the tty.
StandardInput=tty-fail

# Defaults to journal, in case it doesn't adjust it accordingly
#StandardOutput=journal
StandardError=journal

# Log this user with utmp, letting it show up with commands 'w' and 'who'.
UtmpIdentifier=tty7
UtmpMode=user

[Install]
WantedBy=graphical.target

/etc/systemd/user/mysession.target

[Unit]
Description=My session

BindsTo=mysession.target
Before=mysession.target

执行一些重新加载和 loginctl 的操作

# Reloading the configuration so systemd sees it.
systemctl --user daemon-reload
sudo systemctl daemon-reload

# Starting and testing service.
sudo systemctl start mysession # systemd should ask for a password
loginctl # Verify is mysession was able to do session login
systemctl --user start weston
