如何強制我的終端在 Linux 的非 X11 環境中執行高解析度？

我剛剛安裝了 Scientific Linux 並且我有一個高解析度終端，然後我升級了我的影片驅動程序以啟用我的影片卡的一些功能，但是我的終端轉到了正常解析度 80x25，我如何切換（強制）它使用高解析度？

您可以將GRUB vga 模式更改為類似vga=791. 該設置附加到 中的kernel行尾/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
