默认kernel给的tty分辨率是非常有限的,解决的方法就是给kernel传递VGA参数。
1、lilo下设置方法
lilo:linux vga=318
将会启动1024x768x24bpp模式。下面是常用分辨率+色彩所对应的编码
色彩 | 640×400 | 640×480 | 800×600 | 1024×768 | 1280×1024 | 1600×1200 |
4bits | ? | ? | 0x302 | ? | ? | ? |
8bits | 0x300 | 0x301 | 0x303 | 0x305 | 0x307 | 0x31C |
15bits | ? | 0x310 | 0x313 | 0x316 | 0x319 | 0x31D |
16bits | ? | 0x311 | 0x314 | 0x317 | 0x31A | 0x31E |
24bits | ? | 0x312 | 0x315 | 0x318 | 0x31B | 0x31F |
32bits | ? | ? | ? | ? | ? | ? |
如果要默认就设置为1024x768x24bpp模式,可以修改/etc/lilo.conf,加入一下语句:
vga=0x318
然后保存退出,重启即可。
2、GRUB下设置方法
就是在grub.conf启动列表的kernel最后添加vga参数,例如将tty分辨率设置为(800x600x65536)
cat /etc/grub.conf# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda3
# initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux AS (2.6.9-22.EL)
root (hd0,0)
kernel /vmlinuz-2.6.9-22.EL ro root=LABEL=/ vga=788
initrd /initrd-2.6.9-22.EL.img
以下是常用参数列表
linux video=vga16 (640x480x16) <—默认参数,支持最普通的硬件:)
vga=769 (640x480x256)
vga=771 (800x600x256)
vga=788 (800x600x65536)
vga=773 (1024x768x256)
vga=791 (1024x768x65536)
修改后配和zhcon或者cce更加完美。(大分辨率+中文显示+中文输入)
