x11 - Fedora 25 Tigervnc 显示黑屏

Question

系统是Fedora 25。问题是vncviewer显示黑屏。通过比较，vnc 包列表与 Fedora 24 系统中的包列表相同，其中 vnc 查看器显示正确。使用相同的客户端系统访问服务器。

已经审查并尝试了具有此问题的其他线程，特别是 vnc 包要求、$HOME//.vnc/xstartup 权限，以及对 xstartup 脚本的建议。

下面是xstartup脚本:

#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec gnome-session 
# --session=gnome-fallback
# exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic & 
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
startx &

下面是 systemctl status vncserver 的输出:

几年前有几个线程。这些已经过审查和尝试。它们似乎不适用于这种情况。

Answer 1

您可以在这里找到答案:https://www.server-world.info/en/note?os=Fedora_25&p=desktop&f=6 - 就我而言，替换为/home/USER/.vnc/xstartup

...
# end line: comment out and add like follows
#exec /etc/X11/xinit/xinitrc
#exec /usr/bin/mate-session
exec /usr/bin/gnome-session

所以我使用 gnome-session 而不是 mate-session，因为我使用的是 gnome-desktop。没有更多的黑屏(等待一段时间直到传输)。
