使用下面命令改变当前屏幕的分辨率 280 为 1024x768x32

# vidcontrol MODE_280
		

启动时生效，就在 /etc/rc.conf 加入

allscreens_flags="MODE_280"

4.2. 屏幕保护

方法一，编辑 /etc/rc.conf 文件加入

blanktime=”60″
saver=”daemon”
		

方法二，sysinstall

选择
Configure——Console——Saver—–Timeout（设置屏保时间60秒）
在选则 Daemon

屏保文件

# ls /boot/kernel/*saver* | grep -v symbols
/boot/kernel/beastie_saver.ko
/boot/kernel/blank_saver.ko
/boot/kernel/daemon_saver.ko
/boot/kernel/dragon_saver.ko
/boot/kernel/fade_saver.ko
/boot/kernel/fire_saver.ko
/boot/kernel/green_saver.ko
/boot/kernel/logo_saver.ko
/boot/kernel/rain_saver.ko
/boot/kernel/snake_saver.ko
/boot/kernel/star_saver.ko
/boot/kernel/warp_saver.ko
		

屏保预览

# kldload logo_saver
# kldload fire_saver
# kldload rain_saver
		

kldload 不能重复运行，已经载入的屏保不能再重新载入，使用下面命令查看详情。

# kldstat

4.3. 键盘设置

使用linux的用户转到BSD很不适应终端键盘设置

bindkey "^[[1~" beginning-of-line
bindkey "^[[4~" end-of-line
bindkey "^[[3~" delete-char
