TigerVNC不在Fedora上工作

Question

使用本指南：https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-guide/infrastructure-services/TigerVNC/#TigerVNC.adoc#configuring-vncserver

这是一个用户设置，在systemctl start vncserver@:display_number.service步骤中，并适当地更改display_number，我得到以下消息：

Job for vncserver@:0.service failed because the control process exited with error code.

See "systemctl status vncserver@:0.service" and "journalctl -xeu vncserver@:0.service" for details.

运行第一个命令之后：

× vncserver@:0.service - Remote desktop service (VNC)

Loaded: loaded (/etc/systemd/system/vncserver@.service; disabled; vendor preset: disabled)

Active: failed (Result: exit-code) since Mon 2022-01-24 04:09:20 CET; 10s ago

Process: 7899 ExecStart=/sbin/runuser -l (MY USERNAME HERE, REMOVED FOR PRIVACY) -c /usr/bin/vncserver :0 -geometry 1920x1080 (code=exited, status=203/EXEC)

Jan 24 04:09:20 fedora systemd[1]: Failed to start Remote desktop service (VNC).

我该怎么办？我见过其他有类似问题的人，但对于这个特定的文件，没有一个是这样的。

我和你在Fedora 36中经历了同样的问题，当时我遵循了同样的指南。

https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-guide/infrastructure-services/TigerVNC/#TigerVNC.adoc#configuring-vncserver

要使其工作，首先取消对复制到/etc/systemd/system/vncserver@.service的文件所做的更改。基本上又发行了

# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@.service

然后，您还需要执行以下操作

vi ~/.vnc/config
# create new
# session=(display manager you use)
# securitytypes=(security options)
# geometry=(screen resolution)

session=gnome
securitytypes=vncauth,tlsvnc
geometry=800x600 

和

vi /etc/tigervnc/vncserver.users
# add to the end
# specify [:(display number)=(username] as comments
# display number 1 listens port 5901
# display number n + 5900 = listening port
#
# This file assigns users to specific VNC display numbers.
# The syntax is <display>=<username>. E.g.:
#
# :2=andrew
# :3=lisa
:1=fedora
:2=redhat

现在，在执行sudo systemctl status vncserver@:1.service时，我可以看到以下内容：

● vncserver@:1.service - Remote desktop service (VNC)
