Question

大家好，霍尔：

我想在ubuntu 16.04服务器中安装“ vncserver”，但是当我通过“ VNC Viewer”连接时，它始终显示灰屏。我不知道问题是什么，有人可以帮助解决吗？非常感谢！

vnaserver启动日志：

Answer 1

import nltk
from nltk.tokenize import PunktSentenceTokenizer    #Unsupervised machine learning tokenizer.
#This is the custom tagger I created. To use it in future projects, simply import it from Learn_NLTK and call it in your project.
def custom_tagger(training_file, target_file):
    tagged = []
    training_text = open(training_file,"r")
    target_text = open(target_file,"r")
    #Use the trained tokenizer to tag your target file.
    for i in PunktSentenceTokenizer(training_text.read()).tokenize(target_text.read()): tagged.append(nltk.pos_tag(nltk.word_tokenize(i)))        
    training_text.close()   #ALWAYS close opened files! This is why I have included the extra code to this function!
    target_text.close()     #ALWAYS close opened files! This is why I have included the extra code to this function!
    return tagged

将这些行更改为-

#x-window-manager &

gnome-terminal &

我认为这应该有效。还要检查是否已安装gnome-panel，metacity和nautilus软件包（如果未安装的话）。

Answer 2

这对我有用。

yum install gnome* xterm* xorg* -y

我的Vncserver设置有什么问题？
