Ubuntu 16.04 does not display the startup and shutdown screen when booting and shutting down and displays detailed command information, no progress bar and logo, or only purple interface, or no boot screen and other issues resolved

There are mainly the following solutions:

1, if the previous configuration of grub to display detailed command information, then change back on the line, reference: http://www.cnblogs.com/EasonJim/p/7129873.html, this way to restore is generally no problem.

2, if the NVIDIA graphics card has a proprietary driver, or the Intel integrated graphics installed a proprietary driver, the above way to restore the general relevant machine interface, but the boot interface has become full purple. You can refer to the following workarounds:

Note: You must refer to the configuration in http://www.cnblogs.com/EasonJim/p/7129873.html before the operation to restore back.

Open your terminal and enter

sudo apt-get install v86d

And then

sudo gedit/etc/default/grub

Find this line

#GRUB_GFXMODE =640x480

and change this one (of course choose your appropriate resolution)

grub_gfxmode=1440x900grub_gfxpayload_linux=keep

Note: You can try GRUB_GFXMODE=1440x900x24 , but be aware that you specify a color depth. The supported values must be specified. If not, then delete it. More information is available in the manual.

Save the file and enter the terminal

Echo framebuffer=y | sudo tee/etc/initramfs-tools/conf.d/splashsudo update-initramfs-usudo update-grub

Note: Before using this command, the system does not exist, if this file already exists, then use the above command to be very careful, it is recommended to open/etc/initramfs-tools/conf.d/splash, and then add framebuffer= Y to the last. Finally, the following two commands are executed to update their effects.
