Ubuntu’s GUI response is very slow

ByWeiwei Jia

For Dell PowerEdge T630 server, if you install latest Ubuntu desktop version (16.04) or (14.04), you will get a very slow GUI (X-window).

$ inxi -G
Graphics:  Card: Matrox Systems G200eR2 X.org: 1.15.1 driver: vesa tty size: 205x58 Advanced Data: N/A out of X

For Ubuntu 14.04.1, this problem can be solved by following steps.

1, Switch to console mode

CTRL + ALT + F1

2, Stop lightdm service

sudo service lightdm stop

3, Generate Xorg new configure file:

sudo X -configure

4, Move the Xorg configure file to system dir:

sudo mv xorg.conf.new /etc/X11/xorg.conf

5, Open ‘/etc/X11/xorg.conf’ and substitute ‘mga’ to be ‘vesa’

6, Start lightdm again with new configure file

sudo start lightdm

For Ubuntu 16.04, this problem seems to be there and cannot solve by above way.

  • Chinese Charactor Configuration on Fedora 11

    ByEric Ma

    最新的更新版本请看: Fedora 中文字体设置. 使用Linux时我个人倾向使用英文环境系统，而Fedora11在英文环境下中文字体有时会不太好看，经常遇到需要字体优化美化的问题。 以下是我的配置方案，经测试效果还算不错，解决了Fedora 11 中文字体难看的问题： 方案1：使用uming和ukai字体，即AR PL UMing CN等。 关键是使用的字体包如下： 首先要安装这两个字体： cjkuni-ukai-fonts cjkuni-uming-fonts 然后配置一下~/.fonts.conf文件. 使sans-serif serif monospace字体中文使用uming/ukai即可. 我的.fonts.conf文件可以从这里下载(两种选择, 我喜欢前者): https://github.com/zma/config_files 使用Liberation和uming/ukai字体: .fonts.cofn.liberation 使用dejavu和uming/ukai字体: .fonts.conf.dejavu 下载后放到自己的$HOME下改名为.fonts.conf就可以了。 使用uming字体效果如下（请放大后看效果）： 方案2：安装文泉驿字体，这个非常简单，安装相应包即可了。 如果喜欢其它的字体选择性的安装上就可以了，只要注意只安装自己需要的就行了。有人使用微软雅黑字体，首先这是侵权的，其次开源的字体做得其实已经很不错了。 最后将字体平滑选项打开, KDE和gnome都有相关设置方法。 以上内容只是针对使用xft字体系统的设置。对于使用核心字体系统的X程序来说字体依然会出现很丑的情况。 下面是针对emacs的设置方法： 首先需要安装这个字体包： xorg-x11-fonts-misc 注意到在中文系统下emacs的中文显示非常好，而在英文环境中去非常差，我们可以利用这一点，在运行emacs前首先将系统环境设为中文即可。 在~/bin/下建立一文件ema 内容如下： #!/bin/bash rm -f ~/.emacs ln -s ~/.emacs.x ~/.emacs LANG=zh_CN.UTF-8 emacs –fullheight -r $* 然后加入执行权限即可： chmod +x…
