怎样设置Framebuffer

环境：Redhat9.02

启动级别：3

1. 配置内核： #

首先要再编译内核是选中如下几项：

Code maturity level options --->[*] Prompt for development and/or incomplete code/drivers  
Processor type and features --->[*] MTRR (Memory Type Range Register) support  
Block Devices ->[*] Loopback device support
                [*] RAM disk support
                    (4096) Default RAM disk size
                [*] Initial RAM disk (initrd) support  
Console Drivers ->[*] VGA text console
                  [*] Videomode selection support  
Console Drivers -> Frame-buffer support ->[*] Support for frame buffer devices
                                          [*] VESA VGA graphics console
                                          [*] Use splash screen instead of boot logo   

2. 配置Bootloader #

• Grub 修改/etc/grub.conf，在kernel项的最后添加vga参数和fb，例如：

    kernel  /boot/vmlinuz-2.4.20-8 ro root=LABEL=/  vga=0x311 fb:on  
  

• LILO

  修改/etc/lilo.conf，添加vga参数，例如：

    vga=0x311  
  

  修改后执行lilo命令，写入bootloader。

vga参数的可选值如下：

修改后重启系统，会在右上角看到一个Linux的企鹅Logo。
