%@#$@#I finally installed the Chinese input method! I have something to say! ! !

After installing the system and starting to install Sogou input method, it was found that qt4 was removed from 20.04, and the installation of Sogou input method could not be done depending on the installation. Then try to install other input methods. When configuring language support, it pops up directly. I don’t have authenticate? Then I re-logged in after suspending the system, and there was an authenticate window stuck in the upper left corner of the screen, and it was useless to click authentication or cancel? ? ? Then I restarted the computer, and the screen went blank after logging in to the system? ? ? Other ttys are available, but the visual user interface has a black screen, and I can control it with only one mouse cursor. Wandering on the black screen? ? ? And the running sound of the notebook is getting louder and louder, I don’t know if my computer’s performance is not good or the graphic interface card bug can’t be calculated sigh
Then the system returned to normal after reinstalling the system.

Here is the last mention of the method of adjusting the size of the displayed text in the system, and another article about the installation of the Chinese input method. There are two ways to adjust the size, the second is recommended.

Displays adjust the screen magnification ratio

Click the status bar in the upper right corner to enter the setting interface from the drop-down list. Find Displays in the left column of the setting interface. The fourth line Scale of Built-in display is the screen magnification ratio, but there are only two integer options of 100% and 200%. After switching to Fractional Scaling in the fifth line, the fourth line There will be five options: 100%, 125%, 150%, 175%, and 200%. However, after selecting the score size, the screen display quality is indeed worse, so the following method is recommended. By the way, in the top title bar of this interface, you can see Night Light on the right side of Displays, which can adjust the warm red light at night. But after turning it on, the weakest gear is still a bit too red. Redshift is still recommended.

Universal Access adjust text magnification

Open the setting method as above: click on the status bar in the upper right corner to enter the setting interface from the drop-down list. Find Universal Access in the left column of the setting interface, and the second line of Seeing on the right is Large Text. After opening, the system text will be enlarged. In the fourth line of Zoom, there are some zoom functions you can also try, such as the magnifying glass that follows the cursor.
