Change Ubuntu Server Console Resolution

By LotusshaneyTech

in /etc/default/grub I edited the

GRUB_CMDLINE_LINUX=""

line to say

GRUB_CMDLINE_LINUX="vga=0x318"

then update grub settings files

sudo update-grub

Then Reboot

List Of Resolutions

    | 640x480  800x600  1024x768 1280x1024
----+-------------------------------------
256 |  0x301    0x303    0x305    0x307
32k |  0x310    0x313    0x316    0x319
64k |  0x311    0x314    0x317    0x31A
16M |  0x312    0x315    0x318    0x31B


On the new Ubuntu’s, it’s a little different. Edit:

etc/default/grub


But now comment out the line

GRUB_GFXMODE


and make it something like:

GRUB_GFXMODE=1024×768


It’s human readable, so pick your resolution. Once done, you can:

update-grub


and

reboot
