I am using Ubuntu 18.04.1 LTS (updated 2 days ago from 16). The resolution was fine, but accidentally it changed to 1024x768 (4:3) and every time I try to change to 1920x1080 (or any other size) it is not accepted and returns to 1024x768 (4:3).

Apply Changes? Display settings

Choosing resolution

Keep changes popup

Tried several times, restarted pc, but no changes applied. Please help:)

Existing resolutions:

Screnshot of terminal showing 1920x1080 as max resolution available

Check if "nomodeset" is added in your grub. (Like in my case)

goto /etc/default/grub

If yes remove it.

Run command after saving file

sudo update-grub

and reboot the system

First check your monitor code

echo $DISPLAY

Check your device code

sudo lspci |grep -i vga

i solved this problem by configure xorg the solution is creating configuration file in /etc/X11/xorg.conf.d/10-monitor.conf

The 10-monitor.conf should be contain the configuration like this:

Section "Monitor"

    Identifier  "Monitor0"`

EndSection

Section "Device"

    Identifier  "Device0"`

    Driver      "radeon" 

EndSection

Section "Screen"

    Identifier "Screen0"  #Collapse Monitor and Device section to Screen section
    Device                 "Device0"
    Monitor                "Monitor0"
    SubSection             "Display"
        Depth              16
        Modes              "1920x1080_60.00" #Choose the resolution
EndSubSection

EndSection

Goodluck

You could try this, in the guest's Terminal:

sudo apt-get update

sudo apt-get install open-vm-tools-desktop
