ubuntu - virtualbox 全屏

Question

在virtualbox中安装了ubuntu（命令行界面），如何才能全屏显示，必须安装图形界面和增强工具才行吗

Answer 1

The size of the command line seems to be 600*400, even if you install the graphics enhancement tool. I remember that you can change the resolution size in the command line interface, and you need to change some parameters. I haven’t done this in a long time, and I have forgotten it.
You use SSH tools (SecureCRT, etc.) to connect to it, and adjust it as much as you like.

Answer 2

If it’s too small, you can zoom in:

Answer 3

Combining the two answers:

Identify the resolution that your VirtualBox environment supports. Reboot the system and hit c when the grub windows appears appears. This will drop you into the grub console. Enter the commend vbeinfo to see a list of resolutions. Select the resolution that works for you (in my case, 1152x864x32).

Edit /etc/default/grub to modify/create a line GRUB_GFXMODE=1152x864x32 (where you replace the resolution with the one appropriate for your environment).

Edit /etc/grub.d/00_header to modify the line if [ "x${GRUB_GFXMODE}" = "x" ] ; then GRUB_GFXMODE=auto ; fi to be if [ "x${GRUB_GFXMODE}" = "x" ] ; then GRUB_GFXMODE=1152x864x32 ; fi (again, replacing the resolution)

Update grub and reboot: update-grub2 && shutdown -r now
