Problems using the system#

The terminal prompts for a password, but nothing happens when I enter it.#

There is no echo on the screen when entering the password. Just press Enter after entering the password.

The files in the Windows system disk have a small lock icon and become read-only and cannot be modified.#

Enter Windows, open the Control Panel (for Windows 11, please open it through "Windows Tools"), go to "Hardware and Sound" > "Power Options" > "Choose what the power buttons do", click on line 3 "Change settings that are currently unavailable" (Administrator required), find "Enable Fast Startup" under "Shutdown Settings" and uncheck it, click "Save Changes". Or, enter Windows first every time, and then restart to enter deepin.

When multiple systems are installed on the computer, the time of deepin is 8 hours later than that of Windows.#

Windows regards the computer's hardware time (RTC) as local time (local time = RTC), while Linux regards the computer's hardware time as UTC time (local time = RTC+8 = UTC+8). The solution is to let Windows use UTC or let deepin manage time the way Windows does. See here for details .

After turning on passwordless login and automatic login, it prompts "Your login keyring has not been unlocked" when entering the desktop.#

Execute in terminal sudo rm -f ~/.local/share/keyrings/login.keyring.

Self-examination of reasons for control center update failure#

Open a terminal and execute sudo apt update && sudo apt full-upgrade.

Edit the content in the right-click menu "New Document"#

Modify files in ~/.Templates/and ./usr/share/templates/

Window special effects cannot be turned on#

One possible reason is the installation of Huayu input method. If this is the case, please install another input method instead.

A potentially useful solution for no sound from the sound card (mainly applicable to devices with Intel 12/13 generation processors, does not work with microphones)#

Edit /etc/default/grub, GRUB_CMDLINE_LINUX_DEFAULTadd this line snd_hda_intel.dmic_detect=0. If the sound card works normally under Ubuntu, you can extract the driver from the Ubuntu /lib/firmware/intelfolder and replace the corresponding folder under deepin. Original post

Web page translation uses Google Translate, and you can install a translation extension yourself instead.
