First, you have to run the above command (I'm using here the output I get
just as sample, yours should be different):
sm01@stt008:~$ cvt 1024 768 85
# 1024x768 84.89 Hz (CVT 0.79M3) hsync: 68.68 kHz; pclk: 94.50 MHz
Modeline "1024x768_85.00" 94.50 1024 1096 1200 1376 768 771 775 809 -hsync +vsync
Which will tell the Modeline line you have then to add to your Monitor
section of "/etc/X11/xorg.conf" (my Monitor stanza is quite simple):
Section "Monitor"
Identifier "Configured Monitor"
Modeline "1024x768_85.00" 94.50 1024 1096 1200 1376 768 771 775 809 -hsync +vsync
EndSection
After that, restart the X server (I never remember how does one restarts
X server in Debian, but jumping to tty, falling into "init 1" and then
running "startx" should do the trick)... or reboot O:-)

Note: be sure your monitor/VGA card is capable to handle that resolution/
frequency combo, if not you can get an "out-of-sync" message.
