[Bug 299007] [NEW] A screen resolution problem of obtaining 1024x768

[roshanjose]

Public bug reported:

Binary package hint: xserver-xorg-video-intel

I had not much of a problem with screen resolution while working with
Hardy Heron until lately when i upgraded my system to intrepid ibex. The
problem now is that I dont get a resolution that matches my screen
perfectly. I have tried all possible combinations of the resolution and
refresh rates but still no use...

Details of my system

My motherboard: D945GCL

This was not the code originally. I did add my Device configuration and tried adding up the subsystems....

then i tried adding the resolution through command

roshan at roshan-desktop:~$ cvt 1024 768 60
# 1024x768 59.92 Hz (CVT 0.79M3) hsync: 47.82 kHz; pclk: 63.50 MHz
Modeline "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync

roshan at roshan-desktop:~$ xrandr --newmode 1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync
> xrandr --addmode VGA 1024x768_60.00

This is it. I never knew how to to get out of this and get the right
resolution. I concluded myself that 1024x768 fits best because it works
fine for my Windows
