$: export LANG=en_ Us (recovery)_ CN)

2. Update directory

$: xdg-user-dirs-gtk-update

3. Pop up a prompt box and click [confirm]

4. After restart, the prompt box will pop up again. Do you want to change the English folder back to Chinese? Select [no more prompt] and [Cancel] to modify it

Install deepin wine QQ for Ubuntu distribution

  1. Installing the deep wine environment: onhttps://gitee.com/wszqkzqk/deepin-wine-for-ubuntuDownload the zip package (or clone it in GIT) from the page, orBaidu network diskDownload, unzip to local folder, open terminal in folder, inputsudo sh ./install.shOne click installation. If you have installed these dependencies and still report a dependency error in the second step, manually unzip the DEB package and delete the dependency declaration (the method of unzip DEB is mentioned below).
  2. install deepin.com Application container: inhttp://mirrors.aliyun.com/deepin/pool/non-free/d/Download the container you want from the. Click DEB to install it. The following are the recommended containers:

Note: Xunlei Linux version has been officially launched, and has been used happily. SeeUnified information UOS adaptation list

Continue: install QQ / wechat

1. Most of the wechat on Linux are packaged by the web version of wechatelectronic-wechatweweChat, the function of web version is simple, every time you log in, you have to scan the code. And now Tencent seems to have started to disable the login of wechat web version. If it is found that it cannot login to the web version, it can only use crossover to install wechat of Windows version.

2. You can buy a genuine version of crossover19, activate it once, use it permanently, and then install qq9.0 happily. Those who like Tim can also use Tim, but at present, QQ based on crossover has some bus. Use crossover 19 to install wechat. The installation package can directly download the Windows version, and then use crossover to create a 64 bit container for Windows XP. You can install wechat in the container, but there may be some problems during installation" WeChatWin.dll Missing problems“Error message, need to execute the following command to install additional environment:

$: apt-get install libldap-2.4-2:i386

3. Install with dockerTimandwechatDocker environment installation tutorial

4. After installing wechat in the wine environment (crossover / deep), if you find that you can’t input text (in fact, you can input and send, but the text is transparent), you can use this fileriched20.dll(extract password: rofj) replace the C disk under the container of wechat/windows/system32/riched20.dllThe container path is generally in:~/. cxoffice / [your container name] / drive_ c/

5. In the wine environment (crossover / deep in), if you find that there is a black box in the interface that can’t be closed when running wechat, you just need to type “no” in the chat input box, and then delete it to make the black box disappear. (reason: wechat will use the words you enter as keywords to find the matching expression in your existing expression and display it to prompt you to use it, But it’s not very compatible. This function has become a black box, so the only way to manually eliminate the black box is to type keywords and delete them.

6. In the wine environment (crossover / deep in), if you can’t send pictures when running wechat, try to install itsudo apt install libjpeg62:i386The temporary solution is to drag the image file to theCollection, and then forward it from the collection.

New: install the latest version of wechat on Ubuntu 20.04

Please checkAnother article, the process is long, but the degree of adaptation is very good. I am using this method.

  4. Note = > do not rashly try to change the CSS style file of the system theme. If the modified file has syntax errors or other reasons, it is likely that the system will not be able to log in to the graphical interface after power on (in this case, you can insert a U disk to log in to the PE system, then mount the hard disk of the original system, and finally change the error file back).

Ubuntu 18.04 about customizing Plymouth theme to replace boot animation

In fact, I don’t recommend changing the boot animation. One reason is that Ubuntu’s own boot animation is very beautiful and concise. The second reason is that if something goes wrong with this thing, it will be more troublesome for it to be stuck in the boot screen when it comes to recovery. If you insist on tossing, you can gognome-lookLook, here’s an apple themedarwin, password:rc6u

1. Unzip the downloaded Plymouth theme to/usr/share/plymouth/themes

2. Perform the installation

$: sudo update-alternatives --install /usr/share/plymouth/themes/ default.plymouth default.plymouth /usr/share/plymouth/themes/[THEME]/[THEME].plymouth 100

3. To update the configuration, you need to manually select the Plymouth number

$: sudo update-alternatives --config default.plymouth
$: sudo update-initramfs -u

4. Manually change the wrong path parameters

$: sudo gedit /usr/share/plymouth/themes/default.plymouth

When using the [dash to dock] plug-in in Ubuntu, two docks appear at the same time

The solution is to turn off the [dash to dock] switch in the tweak settings. Don’t worry. After turning off, the [dash to dock] still works normally, but there won’t be the embarrassment of two dock columns at the same time.

Ubuntu add software source tips: no release file, ignore the source problem

Ubuntu20.04 taste Guide

  1. Open software and update
  2. Select the source and click Edit
  3. Change the distribution information (please check the dists directory in the repository file of this source on the web page)

Ubuntu solves some problems of software dependency dissatisfaction

=>Take the installation of 16.04 Netease cloud music in Ubuntu as an example

#Gdebi installation package
$: sudo gdebi netease-cloud-music_1.0.0_amd64_ubuntu16.04.deb
$: Dependency is not satisfiable: libqt5libqgtk2
#Ubuntu18.04 reported a dependency problem because libqt5libqgtk2 has been replaced by the new library Qt5 style plugins,
#This library can't be found in the software source. Of course, we can manually install libqt5libqgtk2, but it may lead to new dependency problems

=>Method: unzip the installation package, modify the dependency and repackage it

1. Create a folder under the same level directory of DEB package

$: mkdir netease-cloud-music

2. Unzip the installation package into this folder

$: dpkg -X netease-cloud-music_1.0.0_amd64_ubuntu16.04.deb netease-cloud-music

3. Decompress the control information

$: dpkg -e netease-cloud-music_1.0.0_amd64_ubuntu16.04.deb neteas-cloud-music/DEBIAN/

4. Modify the dependency file (change libqt5libqgtk2 to Qt5 style plugins)

#VIM edit file
$: vim neteas-cloud-music/DEBIAN/control
#Using VIM regularization to search and replace libqt5libqgtk2
#Or manually find the libqt5libqgtk2 declared in the depends line to replace it

5. Generate a new installation package

$: dpkg-deb -b neteas-cloud-music
$: mv neteas-cloud-music.deb netease-cloud-music_1.0.0_amd64_ubuntu18.04.deb

6. Installation

#Use gdebi or dpkg to install
$: sudo gdebi netease-cloud-music_1.0.0_amd64_ubuntu18.04.deb
$: sudo dpkg -i netease-cloud-music_1.0.0_amd64_ubuntu18.04.deb

Install cinnamon desktop launcher in Ubuntu

Cinnamon desktop is also based on GTK, so some GTK themes and icon themes under the dome can also be used directly. After switching the desktop, you can switch themes directly in the settings interface. Deepin desktop can also be installed, which is very beautiful, but it has a serious jam problem and is not recommended. Cinnamon has fewer bugs after installation and can be used normally.

Known problems:

  • Cinnamon desktop notification API may be changed, common wine / crossover applications can not call the notification interface normally, QQ / wehcat can not prompt messages in the notification column, which is not very convenient
  • The input method IBus does not support and cannot be used normally. You can use fcitx Pinyin and Sogou Pinyin based on fcitx framework
  • There is no integrated Bluetooth manager by default. It needs to be installedbluemanBluetooth management
  • The lock screen interface can be very stuck
  • The cinnamon panel (equivalent to Gnome taskbar) is installed by defaultSystem tray It can solve the bug that the tray menu of the wine application becomes a small window and display normally in the panel notification area
  • Cinnamon desktop animation performance is also very inefficient, it is recommended to force the use of independent graphics card

Installation steps:

1. Add warehouse key

$: sudo add-apt-repository ppa:embrosyn/cinnamon  
$: sudo apt update && sudo apt install cinnamon

2. After the installation and logout, you can click the settings button in the login interface to enter a desktop environment

3. Unload cinnamon

$: sudo apt-get install ppa-purge
$: sudo ppa-purge ppa:embrosyn/cinnamon

Solution to insufficient capacity caused by too small Linux partition

=>Before installing Ubuntu 18.04, the / var partition was only given 1.5g, but now it is not enough

  • Method 1
$: sudo apt-get clean
$: sudo apt-get autoremove

If space is still insufficient, use method 2.

  • Method 2

Establish directory soft link solution (soft link and hard link to learn about it)

#Take the / var directory as an example to move out the folder that occupies too much space
$: mv /var/lib /opt
#Establish the soft link of Lib directory under opt to var directory
$: sudo ln -s /opt/lib /var
  • Method 3

If / VAR has no separate partition, the system will use the / home directory by default. If / var space is insufficient, it means / home space is insufficient. In this case, it is recommended to re install the system and re plan the partition structure. Generally speaking, the / var directory 2g-4g is better, or it is not partitioned and shared with / home.

Display the green decompressed Linux package or custom script to the application menu icon list

Many software only decompressed version, although you can decompress and send shortcuts to the desktop, but there is no icon, application list can not see.

=>Installation script (test environment ubuntu18.04 / 20.04) = >github / nojsja / makeIconLink

  • Before installation: please put the icon image (scale 1:1, resolution better than 64px% 64px) into the target folder
  • View description:
$: bash makeIconLink --help
  • Installation instructions:
$: bash makeIconLink --dir /path/to/[exec-file] --target [exec-file-name] --icon [icon-file-name]
  • Unload command:
$: bash makeIconLink --uninstall [exec-file-name]

Win10 + Ubuntu dual system time display error

The default time management mode of Ubuntu and windows is different, so it is normal for dual systems to have time disorder. The default time of Ubuntu is the BIOS time as GMT + 0, which is the world standard time. China is in the East eight district (GMT + 8), so if your Ubuntu location is China, the time displayed by your system is BIOS time + 8 hours. If it’s 8 o’clock in the morning, then Ubuntu will show 8 o’clock, and the time in BIOS is 0 o’clock. When you switch to the windows system, there will be time confusion, because windows will think that the BIOS time is your local time, and the result is that the windows display time is 0 If you synchronize the time under windows and the recovery time is displayed as 8:00, then the BIOS time will be rewritten as 8:00 by windows. When you enter Ubuntu again, the display time will become 8 + 8 = 16:00.

1. Update the time in Ubuntu first
\> sudo apt-get install ntpdate
\> sudo ntpdate time.windows.com

2. Update the time to the hardware
\> sudo hwclock –localtime –systohc

3. Shut down Linux and re-enter the windows system. It is found that the time is normal

Instructions for installing the system in Ubuntu (dual hard disk)

Mainly divided into[GPT disk partition + UEFI boot scheme]And[Traditional MBR disk partition + legacy boot scheme ]
1. Scheme 1 (compatible with GPT + UEFI / MBR + Legacy)
When using UEFI mode to install Ubuntu 18.04, you can choose to use compatible BIOS boot mode to install the system (compatible with traditional boot mode and UEFI boot mode at the same time), that is, do not allocate / boot “Partition, allocate a 1GB” reserved BIOS boot area “(UEFI mode will automatically mount / boot and / boot / EFI), other partitions need at least one root partition”. “8g swap partition is better in the case of 8G memory. In addition, in addition to” reserved BIOS boot area “as the main partition, other partitions are all logical partitions. The last step is very important– Format each partition, otherwise the installation may be wrong!reference resources

2. Scheme 2 (GPT + UEFI used scheme)
To create “EFI system partition”, there is no need to divide the “/ boot” partition (boot boot is booted by grub, but EFI is obviously booted by UEFI). The rest at least need to divide the “/” root partition. Except for the root partition, all partitions are logical partitions. Finally, select “device to install boot” as the “efit system partition” just created.

3. Scheme 3 (traditional MBR + legacy scheme)
In the traditional installation of legacy + MBR, at least the “/ boot” partition (primary partition) and the “/” root partition are divided, and the rest partitions are divided as needed. Finally, the “device to install boot” is selected as the “boot” mount point.

Solutions to the problem that Ubuntu can’t open after installing Netease cloud music 1.1.0
