Unable to change screen size

what is an nvidia 400? do you mean NVIDIA GeForce2 MX 400?

Please can you open a command line by going up to the top taskbar and typing

Applications - Accessories - Terminal

and into that type (or better still copy&paste)

gedit /etc/X11/xorg.conf

and in there do CtrlA to select all the text, CtrlC to copy it and then paste it all in here with CtrlV

We'll have a look and see if we can help fix this easily or if we need to try something else.

Good luck and regards from

"by going up to the top taskbar and typing"

sorry that should have been

"by going up to the top taskbar and clicking on ... "

Try the following:

1: Copy the file /etc/X11/xorg.conf to xorg.conf.bak
2: Edit the file /etc/X11/xorg.conf
3: Modify the screen section:

Section "Screen"
 Identifier "Default Screen"
 Device "nVidia Corporation NV5M64 [RIVA TNT2 Model 64/Model 64 Pro]"
 Monitor "Generic Monitor"
 DefaultDepth 24
        SubSection "Display"
                   Modes "1280x800" (choose your resolution)
        EndSubSection
EndSection

4: Save the file (you need root privileges, you can get them by typing "sudo" in a Terminal)
5: Restart the system

Hope it helps.

Here's what I got:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

Section "Device"
 Identifier "Configured Video Device"
EndSection

Section "Monitor"
 Identifier "Configured Monitor"
EndSection

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

No way, there has to be a lot more? Surely you have a mouse, keyboard and stuff?
Try CtrlA CtrlC to select all that's in the file and CtrlV in here to paste it.

I'm all at sea with xorg nowadays. Where's all the screen resolutions?

lol, sorry not your fault, it's just me

Does

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

Have to become

Section "Screen"
 Identifier "Default Screen"
 Monitor "Configured Monitor"
 Device "Configured Video Device"
 DefaultDepth 24
        SubSection "Display"
                   Modes "1280x800"
        EndSubSection
EndSection

But replacing the 24 and "1280x800" with more relevant figures? The 24 looks pretty unavoidable. Isn't it a standard? 1280x800 looks like a widescreen format?

Here it is all of it-

I already know how to cut and paste

xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

Section "Device"
 Identifier "Configured Video Device"
EndSection

Section "Monitor"
 Identifier "Configured Monitor"
EndSection

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

Ok, can you open a terminal console and do

cd /etc/X11
cp xorg.conf xorg.030209
sudo gedit xorg.conf

and then replace

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

with

Section "Screen"
 Identifier "Default Screen"
 Monitor "Configured Monitor"
 Device "Configured Video Device"
 DefaultDepth 24
        SubSection "Display"
                   Modes "1280x800"
        EndSubSection
EndSection

I think you have to keep the 24 but you should change the 1280x800 to the screen resolution you want and keep the speech-marks. Then click save and reboot. If it goes wrong just use the LiveCd to replace the xorg.conf with the xorg.030209 that you just made.

Good luck wiht this

Which values do you want the screen resolution to be?

If you are still having trouble with this then please post it as a new question. Only the most recent questions tend to get looked at so posting/reposting a question just before america arrives online gives the best chance of getting a good few answers.

If the problem has been resolved then please follow the link to the forum thread and mark it as Solved.

Good luck and many regards from
