Ubuntu 12.04 環境配置

Ubuntu 12.04默認會有一個guest用戶，使用GUEST用戶能夠無需密碼訪問Ubuntu機器。

sudo gedit /etc/lightdm/lightdm.conf

添加

allow-guest=false

修改後

[SeatDefaults]
user-session=ubuntu
greeter-session=unity-greeter
allow-guest=false

最後重啓下lightdm

sudo restart lightdm

或者

sudo apt-get remove gdm-guest-session

 

Ubuntu 12.04 ships with python 2.7.3. You should be able to downloadhttps://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz and follow the README file. The steps should be simple enough.

./configure
make
make install

Note that you don't have to remove python-2.7.3 from your system to install an other version. You can switch between different versions using

sudo update-alternatives --config python
