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.
