when i posted the thread, i had uploaded the screen shot. some how its not showing now.
My monitor supports max resolution of 1440 x 900
after the upgrade, it is stuck at some odd resolution. i clicked on Preferences>monitors to change the resolution. it displayed unknown monitor & frequency as 0.
there was no problem while using 10.04 LTS
how to correct it?

Post your xorg.conf file here. I want to have a look. :)

Then try out the following.

Open Terminal and type:
$ gtf 1440 900 60

Add the output at the end of your xorg.conf file.

I couldn't find xorg.conf file.
Checked in /etc/x11. Only found a xorg.conf.failsafe file.

The native resolution i mentioned earlier was wrong.
i have a Viewsonic VX1940w 19" LCD monitor with native resolution of 1680X1050

in terminal i tried sudo dpkg-reconfigure xserver-xorg , no ouput was observed.
even after restarting system the problem retained.

The output of xrandr is as below
***********************************
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1680 x 1050, current 1680 x 1050, maximum 1680 x 1050
default connected 1680x1050+0+0 0mm x 0mm
1680x1050 0.0*

***********************************

The output of gtf 1680 1050 60 is as below

Since the monitor resolution issue couldnt be solved, i have downgraded to ubuntu 10.04 LTS. Now the resolution is ok.

To moderator: Please close the thread.
 
confused!!

confused!!

It's true Im not confused
^^Did you downgrade or made a fresh install of 10.04??

I am also having some performance issues in 10.10 and would like to downgrade but in ubuntuforms they said that downgrading is not possible and I need to make a fresh install.

BTW I am not a very advanced user of Linux
