lost my resolution

[Guest]

Hello,
I have a lap-top compaq nx 7400, I installed kubuntu 8.10 over, the resolution was good, I bought a new flat screen and I wanted to connect my laptop, the Fn key has not work, I found a command on a forum that I spent

sudo xrandr --output VGA-0 --mode 1280x1024 --output LVDS --off


After restarting the resolution has changed and I have trouble reading the screen. My current xorg.conf

Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
Option "UseFBDev" "true"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"


EndSection


I also try sudo xrandr - output VGA-0 - mode 1680x1050 - output LVDS - off, but it did not change.
How can I find my original resolution?

Re: lost my resolution

solved by unplug the new screen and after reboot, still to configure the pc to switch on the second screen, we can continue on this post or should I open another
