After installing Ubuntu I want to do things

I installed kUbuntu19.10, and Ubuntu19.10, in that it is used in the desktop environment is kde.

Replace the software source & Updates

Installing the first step must be to replace the under domestic source, I use the source Qinghua (Tsinghua open source software mirror sites), paste the following source software Tsinghua's official website Ubuntu19.10.

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ eoan main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ eoan main restricted universe multiverse

# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ eoan-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ eoan-proposed main restricted universe multiverse

Paste Qinghua source of the official website https://mirrors.tuna.tsinghua.edu.cn/

After completion of the replacement source software can be updated.

sudo apt-get update
sudo apt-get upgrade

After replacing the complete software source download speed you will get a little lift.

After all the downloaded installation, restart the computer under it.

About Zoning

Many people tangled partition, not actually good tangled in the "Bird Brother Linux private kitchens" book mentioned, novice recommend a direct points /and a swapcan, just as the experience of people who use Ubuntu partition how points are OK, but after reaching a certain level only need to consider the size of various partitions, as well as future expansion.

After installing the graphics driver software is installed in the graphics driver set, using the following command:

sudo add-apt-repository ppa:nilarimogard/webupd8    #添加PPA更新源
sudo apt-get update                                 #刷新更新源列表
sudo apt-get install nvidia-prime nvidia-settings
sudo apt-get install prime-indicator                #安装双显卡切换指示器

After installation or restart it, and then open a named NVIDIA X Server Settingssoftware, open the PRIME Profilescan select the graphics mode of a column, if there are three, one is the most efficient mode of operation mentioned above, the name Performance Modeof the model, there is a species, called on-Demandthis model to be "enough" mode that automatically adjusts the working efficiency, if the set was computer can also choose to use set of significant ways.

Another way is to install the graphics driver official website provides a way, this way more difficult to be higher than the other two, and the installation is not successful it will result in the issue of a series of uncertain switching machine crashes, fans crazy turn and so, here is simple mention, more detailed article if you need this type of installation your own online search to read.

Modify Firefox dns resolution

Found page load speed is very slow, very slow dns resolve in the course of the Internet if it is found after the installation of ubuntu, perhaps the reason is because access WiFi LAN dns which the response is too slow leads can be modified under the dns server address was 8.8.8.8Alternatively 114.114.114.114, operation is as follows:

Using a text editor (vim, vi, nano just a) to open sudo vim /etc/resolv.confthe configuration file, and then comment out the existing dns records (using #annotations) and then add a line to nameserver x.x.x.xselect dns server.

If you find dns is some software changes, you can also use this command to lock the file, in the course of the operation:

sudo chattr +i /etc/resolv.conf # 加锁
sudo chattr -i /etc/resolv.conf # 解锁
