By default, the Linux terminal/text console will not disable the display after a timeout and will sit indefinitely waiting for you to do something.
In a virtual environment this really isn’t an issue. But on bare metal or a laptop this can be annoying. Thankfully, it’s an easy fix. Obviously this is a system without a desktop environment. This is a server booting straight to terminal and staying there.
Open your grub configuration:
Modify the GRUB_CMDLINE_LINUX_DEFAULT line to enable/disable the display timeout:
If GRUB_CMDLINE_LINUX_DEFAULT already has settings, add your new settings to the end.
... #Console will go blank after 10 minutes (600 seconds) GRUB_CMDLINE_LINUX_DEFAULT="consoleblank=600" # Console timeout is disabled. Display will never go off. GRUB_CMDLINE_LINUX_DEFAULT="consoleblank=0" ...
Save the file and run the grub update:
Reboot when ready and you’re all set.
