The following error occurs during installation: the system is running in low graphics mode.

Your screen, graphics card, and input device settings cocould not be detected correctly. You will need to configure this yourself

Later, the following appeared:

Ubuntu 12.04 the system is running in Low-graphics mode.

Machine environment: Windows XP + virtualbox + ubuntu12.04-i386
Premise: My environment is like this. In virtualbox, set enough memory for the Virtual Machine (more than 512 try) and memory (128 MB), and then start 3D acceleration.
Problem description: If the VM memory is too small, the graphical interface cannot be entered after installation. It even causes the VM to crash. Even if the installation is complete, the following error may occur: the system is running in low graphics mode.

1. The following steps have been performed and fail to work.

Sudo chown lightdm: lightdm-r/var/lib/lightdm

Sudo chown avahi-autoipd: avahi-autoipd-r/var/lib/avahi-autoipd

Sudo chown colord: colord-r/var/lib/colord

Restart

 

2. I tried this step again, but it still won't work.

This is usually caused by the ATI graphics card.

Press CTRL + ALT + F1 to log on

Note: When you enter a password, the cursor will flash and the input does not reflect it. Even if you just enter the password, the press enter will be the same! (The password is not displayed)

My password is a pure number. I don't know if you will have such a problem!

After logon, enter the following:

Sudo apt-Get install fglrx
Sudo reboot

3. Some people have introduced this step. I don't know what it means yet.

This is usually caused by the ATI graphics card. Press Alt + Ctrl + F2 to enter the command line mode. Use the following methods to solve the problem:

Sudo apt-Get update
Sudo apt-Get purge flglrx
Sudo reboot

4. Finally, we used this step to smoothly enter the graphic interface.

 

Note that the following X11 should be capitalized x

01. CD/etc/X11
02. sudo CP Xorg. conf. failsafe Xorg. conf

Restart reboot.

 

 

There are also many methods introduced on the Internet, which may be different for different reasons. Therefore, it is impossible to achieve the goal.
