Fedora 25 Tigervnc显示黑屏

标签: x11 vnc fedora-25

系统是Fedora 25.问题是vncviewer正在显示黑屏。相比之下,vnc包列表与vnc viewer正确显示的Fedora 24系统中的相同。使用相同的客户端系统来访问服务器。

已经审核并尝试了解决此问题的其他主题,特别是vnc包要求,$HOME//.vnc/xstartup permissions以及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 &

以下是systemctl status vncserver:

几年前有几个主题。这些已经过审查和尝试。它们似乎不适用于这种情况。

你可以在这里找到答案:https://www.server-world.info/en/note?os=Fedora_25&p=desktop&f=6 - 就我的情况而言,在/home/USER/.vnc/xstartup

取代
library(twitteR)

client_twitter_id <- "XXXXXXXXXXXXXXXXXXXXXX"
client_twitter_secret <- "XXXXXXXXXXXXXXXXXX"

twitter_token <- "XXXXXXXXXXXXXXXXXXX"

HeaderValue = paste0('Bearer ', twitter_token)


response = POST(
  'https://api.twitter.com/token',
  accept_json(),
  authenticate(client_twitter_id, client_twitter_secret),
  body = list(grant_type = 'client_credentials'),
  encode = 'form',
  verbose()
)

##token = content(response)$access_token
twitter_token <- "XXXXXXXXXXXXXXXXXXXXXXX"
HeaderValue = paste0('Bearer ', twitter_token)




consumer_key <- "XXXXXXXXXXXXXXXXXXXXXX"
consumer_secret <- "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
access_token <- "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
access_secret <- "XXXXXXXXXXXXXXXXXXXXXXXXXXX"

setup_twitter_oauth(consumer_key, consumer_secret, access_token, access_secret)

所以我使用gnome-session而不是mate-session,因为我正在使用gnome-desktop。 没有空白屏幕(等待一段时间直到传输)。

答案 1 :(得分:0)

我正在使用Fedora 27并遇到相同的问题“黑屏”。我尝试了很多“解决方法”,但都没有一个适合我。然后我切换到使用MATE桌面环境,并在几秒钟内使其工作。如果您在此问题上困扰了很长时间,我建议您尝试使用MATE桌面。

如果未安装MATE,则应安装MATE:

dnf -y group install "MATE Desktop"

here is the help of installing MATE. 如下更新xstartup。

#!/bin/sh
#def
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
exec /usr/bin/mate-session

记住要重新启动VNC服务,它应该可以工作。

#systemctl start vncserver@:1.service

希望对您有所帮助。

要在〜/ .vcn /

中为xstartup添加配置的内容
!/bin/sh
#
# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
# exec /etc/X11/xinit/xinitrc
#
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
gnome-session &

答案 3 :(得分:-1)

我在F25中也遇到了gnome的问题。我刚刚修改了xstartup,如下所示,它开始运行良好:

#!/bin/sh

unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

exec gnome-session
#exec /etc/X11/xinit/xinitrc
