Change Ubuntu Server 14.04 Screen Resolution

Is anyone willing to assist me in changing the screen resolution of my Ubuntu Server.

I'm running virtualbox (ubuntu server guest) on a Windows 10 host.

I've checked every link I could possibly find and no luck.

I've also installed the guest additions for it.

Solution 1:

1. Get supported video mode info (to achieve this, I had to install hwinfo)

>sudo apt-get install hwinfo

Then check supported modes (I was interested in setting the resolution to 1280x1024 and set the highest color depth available, so I'm going to check this.)

    sudo hwinfo --framebuffer |grep 1280x1024

The best available mode was shown like this

    > Mode 0x031b: 1280x1024 (+3840), 24 bits
    > Mode 0x0345: 1280x1024 (+5120), 24 bits

Strange as it is, 0x0345 worked from the above two modes only.

2. Edit /etc/default/grub

    sudo nano /etc/default/grub

Uncomment #GRUB_GFXMODE="some value", and change it to your resolution, also add GRUB_GFXPAYLOAD_LINUX line, like in the example below. Also modify GRUB_CMDLINE_LINUX_DEFAULT to reflect the video mode chosen.

    GRUB_CMDLINE_LINUX_DEFAULT="video=0x0345"
    GRUB_GFXMODE=1280x1024x24
    GRUB_GFXPAYLOAD_LINUX=1280x1024x24

Save the changes you have done.

3. Update grub

    sudo update-grub

4. Reboot:

    sudo reboot

If all went smooth, Ubuntu will boot in the resolution you set, for me 1280x1024x24 was fine.

Finally I managed to refine this solution, it's not partial any more.

If connecting with putty, cygwin, you will not experience this issue and the settings above will not change your terminal experience.
