screen doesn't fit in the monitor Geforce4 MX4000

Hello, I have just installed Debian Stretch in my old computer (c2d, 2gb ram, geforce4 mx4000).

Everything went fine and works perfectly, however, I noticed that the screen doesn't fit the monitor. It is not zoomed but seems to be longer in the vertical axis, while the horizontal axis fits ok.

The max resolution of the monitor is 1280 x 1024, and this is the current setting in the OS.

I have checked xrandr and got this, which is correct:

Code:

Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 4096 x 4096
VGA-1 connected primary 1280x1024+0+0 (normal left inverted right x axis y axis) 338mm x 270mm
   1280x1024     60.02*+  75.02  
   1280x960      60.00  
   1152x864      75.00  
   1024x768      75.03    70.07    60.00  
   832x624       74.55  
   800x600       72.19    75.00    60.32    56.25  
   640x480       75.00    72.81    66.67    59.94  
   720x400       70.08  
DVI-I-1 disconnected (normal left inverted right x axis y axis)
TV-1 disconnected (normal left inverted right x axis y axis)

in lspci:

Code:

04:00.0 VGA compatible controller: NVIDIA Corporation NV18 [GeForce4 MX 4000] (rev c1)
	Subsystem: eVga.com. Corp. NV18 [GeForce4 MX 4000]
	Kernel driver in use: nouveau
	Kernel modules: nouveau

It seems that everything is ok, and I can't find any solution... Any ideas?
Thanks

have you tried changing settings on the monitor itself?

that said, the hardware in question is really ancient and i wouldn't be surprised if nouveau bugs out on it.

If nothing else works, create a new Modeline with xrandr and the values from cvt.

Run xrandr to get your connected device name.
Example:

Quote:

xrandr
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384
VGA-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm
1920x1080 60.00*+
1680x1050 59.95
1440x900 74.98 59.89
1280x1024 75.02 60.02
1280x720 60.00
1024x768 75.03 60.00
800x600 75.00 60.32
640x480 75.00 72.81 59.94
DVI-D-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
DVI-D-1 disconnected (normal left inverted right x axis y axis)

Run cvt with your chosen resolution to get your Modeline.
Example:

Quote:

cvt 1280 1024
# 1280x1024 59.89 Hz (CVT 1.31M4) hsync: 63.67 kHz; pclk: 109.00 MHz
Modeline "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync

Use xrandr --newmode to create it
Example:

Quote:

xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync

Use xrandr --addmode to add your new mode.
Example:

Quote:

xrandr --addmode VGA-0 "1280x1024_60.00"

Enable it with xrandr --output.
Example:

Quote:

xrandr --output VGA-0 --mode "1280x1024"

... and don't forget to replace everything bold with your own values.

EDIT: the above instructions will not work in your case as you'll have to remove your existing one first using --delmode/--rmmode and or use a different name (X will keep recreating them), I'll update them ASAP (need sleep).
