A console is a special kind of terminal that is generally supposed to be attached in some direct secure way to the hardware the operating system is running on. In Linux, the console is virtualized in a small way which allows you to use a special keystroke to switch between the virtual consoles.

-n, --console-level level Set the level at which logging of messages is done to the console. The level is a level number or abbreviation of the level name. For all supported levels see dmesg --help output.

2011年7月7日 · Stumbled across this trying to get a larger console for my VM and wanted to add to @mbaitoff's comment. To get the set gfxpayload=keep into the grub2 configuration, you need to add the line GRUB_GFXPAYLOAD_LINUX=keep to your /etc/default/grub.

But I'd like to change things like blinkrate, color, and shape (I want my cursor to be a block, at all times). I've seen people accomplishing this. I just never had a chance to ask those people how to do that.

Some BIOSs supported console redirection to the serial port (for example VA Linux and SuperMicro servers in the 1999+ timeframe). The 8250/16550 UARTS were some of the most popular serial port chips at the time, meaning that they would be the best supported under Linux, and all of them used the 8250 kernel driver (there were many more models in ...

A couple comments asked about or mentioned the possibility of using a browser add-on. I like this approach because I can edit markdown files in any Linux text editor (from nano to vim to Kate) and view the files in Firefox (my browser of choice).
