Grub blur after Nvadia private driver is installed on both Windows 7 and Ubuntu Systems

After a private Nvadia video card driver is installed on both Windows 7 and Ubuntu systems, the shutdown screen turns into a low resolution. To pursue perfection, we recommend that you modify the resolution in the following ways: Modify the grub configuration file first, then generate grub again. cfg: Step1: sudogedit/etc/default/grub change GRUB_CMDLINE_LINUX_DEFAULT = "quietsplash" to GRUB_CMDLINE

After a private Nvadia video card driver is installed on both Windows 7 and Ubuntu systems, the shutdown screen turns into a low resolution. To pursue perfection, we recommend that you modify the resolution in the following ways:

First modify the configuration file of grub, and then regenerate grub. cfg:

Step 1:

Sudo gedit/etc/default/grub

Set

GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash"

Changed:

GRUB_CMDLINE_LINUX_DEFAULT = "video = vesafb vga = 790 quiet splash"

Note that 790 represents 1024x768x32 k. You can change the value as needed. This data must be correct and the number is incorrect, which may cause the boot screen not to be displayed or deformed. If there is no corresponding value, you can use 790 or a value close to the actual resolution.

Add

# GRUB_GFXMODE = 640*480

Changed:

GRUB_GFXMODE = 1024*768

Step 2:

Sudo gedit/etc/grub. d/00_header

In

Set gfxmode =$ {GRUB_GFXMODE}

Add in the next line

Code:

Set gfxpayload = keep

Step 3:

Sudo update-grub

Step 4:

Sudo reboot
