Maybe one of these:

sudo xrandr --addmode CRT-0 1024x1080

Or

sudo xrandr --addmode DFP 1024x1080

Remember it's not * it's this one x

1024x1080 is a very strange graphic mode. It has more pixel vertically then horizontally. Most monitors should be unable to display it without distorting the view.
What kind you monitor do you have? A TFT or LSD (flat) or an old CRT (quite large)? That is the ratio of width / height? Typical values are 5:4, 4:3 or 16:9.

CRTs have an aspect ratio of 3:4 (the height is 3/4 of the width) but they are able to display many other formats.
If you choose a format that does not match a ration of 3:4, the picture will be too wide or too tall. A circle for example will never be round but look like an ellipse instead. The display system in Ubuntu can read the metrics of the display and will not offer a resolution with bad aspect ratio.
This behaviour can be overwritten by manually configuring your display modes in /etc/X11/xorg.conf.
But be warned: it is a rather complex procedure and for a CRT you need to enter several technical details of your monitor like the maximum frequencies and so on. Bad entries can break the graphic system of Ubuntu.

If your monitor is digital and the pc itself has a digital monitor connection port BUT you're not using a digital cable that will cause Display/graphic issues with ubuntu..get a digital cable and it should work fine.

Can you help with this problem?
