我刚刚安装了 Scientific Linux，并且拥有一个高分辨率终端，然后我升级了视频驱动程序以启用视频卡的某些功能，但我的终端却变成了常规分辨率 80x25，我该如何切换（强制）它使用高分辨率？

您可以更改GRUB vga 模式类似于。该设置附加到中的行vga=791末尾。kernel/etc/grub.conf
例如：
# grub.conf generated by anaconda
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-194.11.1.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-194.11.1.el5 ro root=LABEL=/ vga=791
initrd /initrd-2.6.18-194.11.1.el5.img
