Unable to change the resolution of newly connected monitor

[psrdotcom]

Hi,

I have connected my Ubuntu 11.04 to a monitor with max resolution support 1366x768.

But in Ubuntu it is having maximum of 1024x768.

Please help to change my desktop resolution.

The detect monitor button doesn't have any effect.

When you set the resolution to the maximum setting, what does it look like? My monitor has a max resolution of 1440x900, but the max resolution setting provided in 11.04 works great. I have yet to see an option in any OS that provides the resolution of my specific monitor, but usually the max setting works.

Where I can set the screen resolution to MAX .. In Monitors .. it was displaying only 1024*780 resolution .. There is no option like MAX setting resolution.

Do you need any more inputs?

Which monitor model is it?
What does

xrandr -q
show ?

When I ran the command I got the following output.

$ xrandr -q
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 410mm x 230mm
1366x768 59.8 +
1024x768 75.1 60.0*
800x600 75.0 60.3
640x480 75.0 60.0
720x400 70.1

I don't know, how the problem resolved.

I created one user and logged in to that user account. My screen resolution automatically changed.
