Ubuntu prompts "running in low-graphics mode". How can this problem be solved?

I recently tried programming in linux and installed ubuntu, so I got another iso file and installed wubi ...... The result was an abnormal shutdown. The prompt "The system is running in low-graphics mode" is displayed. (The selected Chinese language is installed and replaced with English... in The middle ......). I am a ATI graphics card. Several methods have been searched, such as installing fglrx to replace the old driver, restoring the system, and so on. The last reinstallation was completed.

Another reason for reinstallation is that wubi is installed slowly (I installed it in ssd), and it is easy to get started when the system is shut down abnormally, it is said that wubi was used as a program for windows, and files were easily damaged. I don't believe it anyway. As shown in the preceding example, the hard disk is partitioned, installed, and installed with necessary software. The graphics card driver ...... Then, take a rest and watch a movie.

After watching the video for a few minutes, the screen flashed and the video continued. After a while, I wanted to see how far it was installed. In any case, I couldn't return the full-screen video! There is no control panel at all, and the HDMI output may be a large scale, and tty1 is black ...... Hard reboot. Then there is tragedy. The system is running in low-graphics mode.

This really Nima ...... Cannot start x. Do you want to view the webpage in terminal? I'm going ......

There is a previously downloaded driver in the computer. You can reload the graphics card driver. Result ...... How to enter Chinese characters in Nima pure terminal mode? All are diamond blocks! (The downloaded driver is in the "download" folder)

While eating, I thought all the way. Finally, I decided to mount the ext3 hard disk in windows (Dual System) and try to pull the file out to the root directory. Then use the Ext2Fsd (probably this name), the amd-xxxx64_64.deb moved out, and then directly renamed amd, restart into ubuntu, dpkg installation, reboot, Resurrection ~~

Experience:

1. Do not restart the system during updates (do not restart the system whenever possible );

2. When you encounter The problem of The system is running in low-graphics mode, reinstall The graphics card driver;

3. If the resolution of the monitor is large (1920x1080), if the screen is scaled (I adjusted it to the maximum) to adapt to the screen, the restart will fail. The solution is as follows: sudo aticonfig -- set-pcs-val = MCIL, digitalhdtvdefaunderunderscan, 0
