如何增加 TTY 控制台的数量？

7

我经常发现完全从命令行工作很方便，并且喜欢同时打开几个 tty“控制台”。

如何使我的系统默认拥有超过传统的 6 个 tty 控制台 (CTRL-ALT-Fn)？

同样随着向 SystemD 和 Gnome 的过渡，tty 控制台数量是否真的下降了？有时我似乎很难打开一个，更不用说打开几个了，而且经常会出现几个（CTRL-ALT-Fn）组合都导致 GUI 而不是 tty 的行为。

如果重要的话，我正在多台机器上运行 Ubuntu 18.04 和 18.10 的组合。

在 LXC 内运行的 Ubuntu 18.04 上尝试在控制台上以 root 身份登录时无法登录且没有密码提示

0

我在运行 Proxmox 4.4-24 (Debian 8.11) 的几个节点中的 LXC 容器中安装了几个 Ubuntu 18.04.2。

在其中任何一个上，当我尝试在控制台上以 root 身份登录时，我输入“root”，按回车，几秒钟后我得到“登录不正确”。

以非 root 用户身份登录可以正常工作。

在运行 Proxmox 5.3-11 (Debian 9.8) 的多个节点中的 LXC 容器内的其他 Ubuntu 18.04.2 安装中，以 root 身份登录可以正常工作。

我什至如何开始调试这个问题？

启动缓慢并在启动时冻结

0

我正在使用带有 4.15.0.29 通用内核的 Ubuntu 18.04。启动过程需要很长时间，我注意到启动时字体样式发生了变化。我已经在谷歌上尝试了很多东西，但它们什么也没做，所以我恢复到安装后快照（这个），因为没有其他解决了我的问题。（我正在使用时移）

PS 我尝试自己进行一些调试和研究，但 3 小时后我一无所获。

PSS 这在内核 4.18 上仍然存在。（为此而尝试）

HiDPI 控制台字体非交互式

3

非交互式更改控制台字体的正确方法是什么？

我有一个 HiDPI 显示器，需要更大的控制台字体。我可以使用以下方式进行交互设置：

$ sudo dpkg-reconfigure console-setup
# Select UTF-8 -> Guess -> Terminus -> 16x32
update-initramfs: deferring update (trigger activated)
Processing triggers for initramfs-tools (0.130ubuntu3.5) ...
update-initramfs: Generating /boot/initrd.img-4.15.0-43-generic

但是，如果我尝试以非交互方式设置它，如下所示：

 $ sudo debconf-set-selections <<EOF 
 console-setup console-setup/charmap47 select UTF-8
 console-setup console-setup/codeset47 select Guess optimal character set
 console-setup console-setup/codesetcode string guess
 console-setup console-setup/fontface47 select Terminus
 console-setup console-setup/fontsize string 16x32
 console-setup console-setup/fontsize-fb47 select 16x32 (framebuffer only)
 console-setup console-setup/fontsize-text47 select 16x32 (framebuffer only)
 EOF

这不起作用。跑步setupcon没有效果。如果我检查/etc/default/console-setup，我会看到字体信息在我运行时更新dpkg-reconfigure，并且dpkg-reconfigure还会触发update-initramfs，所以似乎更多的是dpkg-reconfigure我debconf-set-selections没有触发。我如何找到这些动作并在我之后触发它们debconf-set-selections？

更改 Ubuntu Server 18.04 LTS 仿生控制台屏幕分辨率

3

在物理机或 VirtualBox 上运行 Ubuntu 18.04 服务器？
您需要/想要使用屏幕的完整原始分辨率吗？高于 640x480 / 800x600？

那么你可能会像我一样被卡住，因为过去在 14.04 和 16.04 上工作的解决方案在 18.04 上不起作用。

要解决的问题（目标）

hwinfo --framebuffer给出一个空输出 -> 找到另一个解决方案
将常用行添加到 /etc/default/grub，仅在引导的第一阶段有帮助。GRUB2 完成工作后，分辨率切换回较低的值 -> 也解决此问题
排除基于 xorg 的工具，如 xrandr（这是默认情况下没有 GUI 的服务器）
在带有 GUI 的桌面系统的情况下增加 VT1-7 ( Ctrl+ Alt+ F1, F2- ) 分辨率F7
将分辨率设置为 1280x1024

如何在 tmux 会话中配置 conky？

我想在我的tmux会话中有一个自定义页脚conky，我的 conky 配置按照 conky 官方推荐screen：

conky.config = {
    out_to_x = false,
    out_to_console = true,
    total_run_times = 1
};
conky.text = [[${time %H:%M}|free space:${fs_free /}|$loadavg|free mem:$memeasyfree]]

tmux仅包含一行.tmux.conf：

set-option -g status-left "#(conky -i 1 -c ~/.conkyintmux) |"

但是当我开始时tmux，页脚行显示

13:48|free0:bash*                                     "D830-2" 13:48 06-Sep-18

并且没有任何.tmux.conf（不叫 conky），它会读

[0] 0:bash* "D830-2" 13:53 06-Sep-18

预期输出：

如何将脚本命令输出转换为纯文本

1

我正在使用script-command将终端的输出保存到文件中。

但是，它提供了一些额外的字符，如square-like字符和其他文本加密字符。

man script命令告诉，通过使用-q标志/选项，它给出了相当多的输出，而不会将开始和完成消息写入标准输出，但它不会删除额外的字符。

我怎样才能得到以下信息：

1）使输出文件与终端输出完全相同，删除多余的字符。

2）在生成的文件中，由于纯文本 - 没有颜色（与终端不同），我无法直接弄清楚input commands，因为我输入的输出和命令出现相同的字体，

我可以将命令设置为比其他输出粗体或易于识别吗？

不幸的是，最近的系统升级似乎破坏了我的显卡驱动程序，所以我将重新安装最新的 Ubuntu 版本（18.04）。在此之前，我想导出我的 gpodder 播客订阅。由于上述问题，我只能通过控制台（Ctrl+Alt+F...）登录，“而不是 GUI 方式”。我所要求的可能在官方 gpodder 文档https://gpodder.github.io/中列出，但是因为我对这种计算机的知识并不了解，有人可以向我列出哪个序列我必须输入多少命令才能将它们存储在一个 OPML（或任何最好的格式）文件中，比如我的主目录？
