Troubleshooting

1 Perl can’t locate libxml

$sudocpaninstallXML::LibXML

$sudoapt-getinstalllibxml-libxml-perl

2. newuser的terminal文件没有颜色显示

因为缺乏.bashrc所致.

newuser@server$ cp /home/administrator/.bashrc /home/newuser

newuser@server$ source ./bashrc

3.Ubuntu is running in low-graphics mode

ctrl+alt+F1切换到控制台

user@server$ sudo mv /etc/lightdm/lightdm.conf /etc/lightdm/lightdm.conf_old

user@server$ sudo reboot

4.ERROR: Cannot launch Jack server

user@server$ sudo vim ~/.jack

SERVER=true -> SERVER=false
