When you install Ubuntu system or installed after a good landing, and did not successfully enter the system, but stuck in the logo interface, or "purple screen" (the whole screen is purple).
The problem is the graphics card and Ubuntu18.04 have trouble.
Note that only for the solution 2 inside the dual system and have been forced to install a success, and the case where power enters the Ubuntu Grub2 guide interface.
Solution:
Method 1: If you are installing into the U disk, selected by the cursor "install Ubuntu", press "e" to enter the edit page, find
quiet splash --- or quiet splash $ vt_handoff
It will be replaced
quiet splash $vt_handoff acpi_osi=linux nomodeset
Then press F10, and saved into the system can either begin the installation.
After the end of the installation according to the installation steps, the system will remind you to restart.
After the restart, you still need to modify the "quiet splash" before they can successfully enter, or otherwise get stuck in the logo interface, how to permanently get rid of this problem? The following:
① Open a terminal in the desktop right
② enter the following code (note enter the first line of code, the system will prompt you to enter your administrator password.)
sudo chmod +w /boot/grub/grub.cfg sudo gedit /boot/grub/grub.cfg
③ In the pop-up edit window grub.cfg press ctrl + F key search "Splash"
④ before, found
quiet splash --- or quiet splash $ vt_handoff
Should find three, are replaced
quiet splash $vt_handoff acpi_osi=linux nomodeset
⑤ press ctrl + S saved (or stored direct manual point)
⑥ window and then switch to the input terminal
sudo chmod -w /boot/grub/grub.cfg
Complete, the next time they enter the system without modifying the grub options page of friends ~
Method 2: If at this time your Ubuntu dual system installed, and there is bootable floppy, you will enter the Grub2 Ubuntu boot screen at startup, select Ubuntu advanced options, follow the prompts to enter the grub interface
turn up
quiet splash --- or quiet splash $ vt_handoff
It will be replaced
quiet splash $vt_handoff acpi_osi=linux nomodeset
Then press F10, and saved into the system.
Open a terminal and then right at the desktop
enter the following code (note enter the first line of code, the system will prompt you to enter your administrator password.)
sudo chmod +w /boot/grub/grub.cfg sudo gedit /boot/grub/grub.cfg
In the pop-up edit window grub.cfg press ctrl + F key search "splash"
as before, find
quiet splash --- or quiet splash $ vt_handoff
Should find three, are replaced
quiet splash $vt_handoff acpi_osi=linux nomodeset
Then press ctrl + S saved (or stored direct manual point)
and then switching to the input terminal window
sudo chmod -w /boot/grub/grub.cfg
Complete, the next time they enter the system without modifying the grub options page of friends ~
