ubuntu重新启动就黑屏的原因以及解决方法:
显卡驱动没有装好,需要安装ubuntu的显卡驱动,解决方法如下:
安装完ubuntu后,打开“系统” → “系统管理” → “硬件驱动” → 选择“ati驱动”进行安装,重启即可。
如果还是黑屏,需要按“ctrl+alt+f1”快捷键进入shell 界面,打开/etc/X11/xconf.org文件,根据以下代码提示进行修改,例如:
# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
