Solving the abnormal method of the Ubuntu switch maneuver painting

Lenovo's Notebook, the graphics card nvidia gt218m, defaults to using open source drivers, but hangs and then wakes up on the black screen without returning to the desktop.

1. WORKAROUND: Install nvidia proprietary driver $sudo Apt-get installation nvidia-current

New problem: Boot logo and on/Off animation are not normal, only display text logo

Workaround: 1, edit/etc/default/grub file

$sudo Gedit/etc/default/grub

Will

grub_cmdline_linux_default= "Quiet Splash"

Switch

grub_cmdline_linux_default= "VIDEO=VESAFB vga=845 Quiet Splash"

Note: 845 is the display mode number, which represents the 1366x768x16m, can be modified according to their own circumstances to the corresponding number. This data must be correct, and the number is incorrect, it is likely to cause the boot screen can not be displayed or distorted.

Use the following command line to query for various modes:

$sudo HWInfo--framebuffer

...

Mode 0x034d:1366x768 (+5472), bits

...

The above 0x34d in decimal, which is 845.

Remove the note below and change 640x480 to the resolution that fits your display, such as 1024x768

#GRUB_GFXMODE =640x480

grub_gfxmode=1280x800

2, edit/etc/grub.d/00_header (This step seems to be not)

$sudo Gedit/etc/grub.d/00_header

Found it

Set Gfxmode=${grub_gfxmode}

Add on its next line

Set Gfxpayload=keep

3, update Grub$sudo Update-grub

After rebooting, you should be able to see the HD Grub menu and on/off animations.

The above methods were tested in Ubuntu 12.04 and Ubuntu Kylin 14.04.
