How to change the resolution of the Bash for a Debian VM?

I'm trying to learn how to use Linux with a Debian 7 VM that has no GUI.

The 640x400 window I'm working in feels a little constricting and would like to make it bigger, say 1024x768.

How can I do this?

Hello, I no longer use this type of work flow. I was just getting my feet wet. I prefer ssh now :)

Solution 1:

What you basically want to do is change the resolution of the framebuffer. Here's the process I used (supposing that your desired resolution is 1024x768, and that Hyper-V's framebuffer supports this resolution):

1. Open up /etc/default/grub with superuser privileges: sudo nano /etc/default/grub
2. Uncomment/add the following lines:

   GRUB_GFXMODE=1024x768x32
   GRUB_GFXPAYLOAD_LINUX=keep

3. Save the file and exit: Ctrl-O, Enter, Ctrl-X
4. Run update-grub as superuser: sudo update-grub
5. Reboot, and (hopefully) enjoy a higher-resolution console!
