NetBSD 7.1（GENERIC.201703111743Z）amd64
在没有 gui 的 TTY 中，启动时设置了更好的屏幕分辨率，但字体确实太小了。
那么如何改变这种情况
在 debian dpkg 上，在 grub 中重新配置控制台设置
GRUB_GFXMODE=800x600
我找到了 wsconscfg 的例子：
wsconscfg -t 80x50 -e vt100 3
但我得到
wsconscfg: WSDISPLAYIO_ADDSCREEN: Device not configured
我查看 man wsconscfg wsconsctl wscons wsdisplay vga 等。
所有这些都链接到另一个，但我找不到方法。
答案1
在看/etc/wsconf.conf。它允许您配置启动时使用的终端环境，包括使用不同的字体。在 PC 硬件上，您只能使用几种文本大小：80x25、80x43 和 80x50。 80x50 是最小的字体（但屏幕上可以容纳 50 行，所以非常有用。）
如果您使用 80x50 模式（在您的示例中提到），您需要首先加载 8 像素高的字体；其配置位于我提到的文件顶部附近。您还可以使用该wsfontload命令从 shell 加载字体。
请注意，我从未将 NetBSD 系统配置为 80x43 模式。我认为它可能还需要 8 像素高的字体。

如果有人正在寻找更好的线索，我将发布我的线索/etc/wscons.conf以供参考。这不会启用latin2（而是启用 80x50 屏幕），但这可以通过注释掉几行并取消注释其他几行来完成。
