1.设置ubuntu显示分辨率之后，重启之后却出现了问题，登录界面只出现了以前的左上部分，此时用户名输入框根本看不到：

修改方法：

在文件系统中找到这个文件:/etc/X11/xorg.conf ，然后在xorg.conf文件中找到如下区域:

......Section “Screen”

Identifier “Default Screen”

Monitor “Configured Monitor”

Device “Configured Video Device”

Defaultdepth 24

Option “AddARGBGLXVisuals” “True”

SubSection “Display”

Depth 24

Virtual 1024 768

.....

以上区域的内容视电脑而异，其实重点是用红色标识的Virtual 这个词后面的数字就是登录界面的分辨率，将其修改为正常或去掉就可以了(注意，不要超出使用的分辨率)

2.在Vmware下正常，正常模式下启动无法进入图形模式：

修改方法：

在root用户有下：

1.init 1

2.Xorg -configure

3.在主目录下应出现x.org.conf.new，用X -xf86config /root/xorg.conf.new

4.用Ctrl+Alt+Backspace可以退出X服务器，如果无法退出，可以直接使用init 1

5.将xorg.conf.new拷贝到/etc/X11/xorg.conf

重新启动电脑即可。注意：用dpkg-reconfigure xserver-xorg方法无效

可以使用displayconfig-gtk，然后再设置显示器和屏幕显示即可。

以下是份网友的参考配置：

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder57) Thu Jul 17 18:39:19 PDT 2008

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
# sudo dpkg-reconfigure -phigh xserver-xorg
