Galaxy Kirin FAQ

1. Installation issues

​ ​ 1) The new partition sda1 for advanced installation must be the /boot partition, and sda2 is the root partition?

A: For example, on the Feiteng platform, the new partition sda1 for advanced installation must be the /boot partition, sda2 must be the root partition, and these two partition types must be primary partitions. Except for these two partitions, other partition types can choose primary partitions or logical partitions, but the number of primary partitions on a single hard disk cannot exceed 4

​ ​ 2. Version issues

​ ​ 1) View version

A: Right-click the blank part of the status bar and select "About Galaxy Kylin", or execute the command line: cat/etc/.kyinfo

​ ​ 2) Check the serial number

A: Execute kylin-verify

3. Startup problem

​​ 1) When the monitor is not connected, the system fails to start

A: Delete the /lib/aarch64-linux-gnu/plymouth/renderers/frame-buffer.so file

​ ​ 2) When booting, it will stop at the Galaxy Kirin logo interface.

A: Use the CD to boot into livecd, check whether the partition is mounted, unmount it if mounted, and perform fsck on the system root partition:

sudomount/dev/sda1/mnt

Sudofsck-y/dev/sda1

Sudoumount/dev/sda1

sudomount/dev/sda2/mnt

Sudofsck-y/dev/sda2

Sudoumount/dev/sda2

sudoreboot

4. Login issues

​ ​ 1) The graphical interface login crashes, or enter the correct username and password to jump to the login interface again.

A: Switch to the background, enter the home directory, chown-R username:username.Xauthority, if the problem still cannot be solved, check the ~.

​ ​ 2) Forgot user password

A: The user password can be modified by the administrator user using passwd;

If you forget the administrator user password, you can put the CD into the CD-ROM drive, restart the system into livecd mode (or mount the system hard disk to other Linux systems), modify the password field in the /etc/shadow file, and replace it with a known password field

​​ 3) When creating a new user, the user name is not displayed on the lock screen or is displayed as unknown.

A: Check the mate-screensaver-preference package version and upgrade this package

​​ 4) The problem of prohibiting root user login

A: Since the root user has almost all permissions, in order to avoid system problems caused by misoperation and improve system security, after the system is installed, the default root password is randomly changed, and logging in as the root user is prohibited. If you need to use the root user's permissions, you can use the sudo command; if you need to switch to the root user, you can use the "sudo-i" command to ensure the randomness of the root password.

5. Activation issues

​ ​ 1) The trial period has not expired, but the phone is shut down after half an hour

A: Delete kyhwid. If the problem still persists, check the output of the sudokylin_activation_check command to determine the specific problem, or replace the authorization file;

​​ 2) Entering the wrong activation code leads to abnormal system service period

A: After deleting /etc/.kyactivation, re-enter the correct activation code.

6. Display problem

​ ​ 1) The status bar icon of Inspur all-in-one machine appears in the middle of the status bar, and the calendar cannot be opened.

A: The machine will recognize two monitors, just turn off the unknown monitor.

​ ​ 2) There is no screen saver setting in the control panel

A: The command line mate-screensaver-preference can bring up the screensaver setting window

3) The taskbar disappears

A: Delete .config/ in the home directory, and the taskbar will return to normal after restarting the machine.

​​ 4) The mounted hard disk needs to be hidden in the mounting icon on the desktop

A: Solved by gsetting: gsettingsetorg.mate.caja.desktopvolumes-visiblefalse

5) Ctrl+alt+T cannot open the terminal

A: Delete the .config file in the current user’s home directory and then restart the system

​ 6) Sogou Wubi input method garbled characters

A: Restart the input method, kill the fcitx and sogou-qimpanel processes, execute killallfcitx and killallsogou-qimpanel, and then fcitx-autostart& and sogou-qimpanel& in the background.

​ 7) There is no desktop display in the system on the Inspur server

A: Use the mouse to select <Desktop Background>, then select <Monitor>, and turn off the laptop monitor.

​​ 8) The graphical interface is configured with dual-screen mirroring, but it does not take effect after restarting the system.

A: Use the user's display profile to overwrite lightdm's, and then restart the lightdm service

Sudocp~/.config/monitors.xml/var/lib/lightdm/.config/

sudoservicelightdmrestart

​ 9) After logging into the system, the icon cannot be loaded and "Starting caja" pops up.

A: Rename or delete the .config directory in the user’s home directory

10) Start menu cannot be opened

A: Delete the ./face file

7. Network problems

​​ 1) Ethernet connections increase and some connections fail

A: Delete the network connection configuration file under /etc/udev/rules.d/, restart the machine and then automatically generate it

​ ​ 2) SSH connection to the server is slow

A: Comment the ForwardX11 line in the /etc/ssh/ssh_config file

​ 3) The network becomes intermittent after someone changes the configuration.

A: Check the logs to determine the problem. Situation 1: If the owner or permissions of the configuration file in the /etc directory are modified, then modify them one by one according to the correct configuration back to the original configuration.

​​ 4) Switching users prompts that the host cannot be resolved

A: The hostname is modified, but /etc/hosts is not modified simultaneously. As a result, the host name in /etc/hosts is changed to the host name obtained by the hostname command.

5) Servicenetworkingrestart failure problem

A: Since the current system uses network-manager by default, the network cannot take over the network, causing the operation of the network service to fail. Therefore, if you need to restart the network service, use the command "servicenetwork-managerrestart"

8. Application issues

1) Drawing software

A: The current desktop version has integrated Gnome drawing tools and GIMP image editor.

​​ 2) Dameng database-related errors are prompted when installing the software

A: Uninstall the Dameng database first, then install the software that needs to be installed, and then install Dameng back after installation (pay attention to backing up database-related data)

​ ​ 7) gtk function reference error when compiling application

A: Add "`pkg-config--cflags--libsgtk+-2.0`" to the Makefile to make the program automatically connect the gtk2.0 header files and libraries

9. Other issues

​ ​ 1) Know the system installation time

A: It is recommended to use the tune2fs-l/dev/sda1|grepFilesystem command to obtain the file system creation time as a reference for the installation time. /dev/sda1 is the partition that needs to be viewed.

​​ 2) Online update and push patch package failed

A: Check the network configuration and DNS address configuration. After confirming that they are correct, open the command line terminal and execute the kylin-update-manager-auto command to view the printed information and confirm the specific problem.

3) The U disk is manually mounted, and the Chinese characters in the U disk are displayed as garbled characters.

A: Because of the character set, you need to add parameters after mount:

“ sudomount–oiocharset=utf8/dev/sdb1/mnt

​ 4) Does Galaxy Kirin desktop operating system support multiple partitions to be mounted to the same directory?

A: When multiple partitions are mounted to the same directory, the directory will only display the contents of the last mounted partition. After the last mounted partition is unmounted, the directory will display the second to last mounted partition, and so on.

​​ 5) What to do if there is insufficient disk space

A: When an application reports "diskfull", it usually means that ordinary users have no space to create or expand files, which may cause the user to be unable to log in. But generally speaking, the system administrator (root) can still log in to perform some management operations, such as deleting some temporary files, such as some contents in the /tmp directory and /var/log directory, and recovering some disk space. If you need to increase space, consider expanding the partition. One way is to create a new partition (you may need to add a new hard disk), then mount the partition to a directory that takes up a lot of space, such as /opt, /home, transfer the contents of the original directory to the new partition, and then modify /etc/fstab so that the partition is mounted to the specified directory by default. Another method that requires a partition with insufficient space is the LVM (logical volume) format. At this time, you can use pvcreate to create a new LVM physical volume, use lvextend to extend the logical volume with insufficient space, and then use resize2fs to expand the partition (you need to uninstall the partition, if it is the / partition, you need to operate under the rescueshell). For related commands, please refer to the lvm related manual. Caution is recommended.
