Screen Resolution problem

[volpne]

Hi all,

I have searched the forums, but as Im totally new to Linux (24 hours), I cant find an answer that I can understand, so I apologize in advance.

The problem is screen resolution.

I cant get the resolution higher than 800x600, in fact in the System Preferences Screen Resolution there are only two options 800x600 or 640x480.

Im running,
Ubuntu 8.04 - the Hardy Heron
on a
AMD 64 bit machine
the screen is
LG Flatron L1953TR
the motherboard is
ASRock ALive NF7G-HD720p
the on board graphic card is
NVIDIA GeForce7.

Ive tried the Synaptic package for Nvidia, no joy.

Ive also tried the Terminal. First I tried,

> cp /etc/X11/xorg.conf /var/backups/X/xorg.backup

and got the answer

> cp: cannot create regular file `/var/backups/X/xorg.backup': No such file or directory

continued with

> sudo gedit /etc/X11/xorg.conf

and got this

>

Every post Ive read shows that this is not the right response.

What do I do next?

Thanks in advance

try this :



sudo nano /etc/usplash.conf
you will got something like that



# Usplash configuration file
# These parameters will only apply after running update-initramfs.



add the required resolution



# Usplash configuration file
# These parameters will only apply after running update-initramfs.

xres=1280
yres=800


Or set x & y as you want then reboot and type :



sudo dpkg-reconfigure usplash
then check for the new settings -- System > Preferences > Screen Resolution and select the new one.

Thanks housam, for your speedy reply.

I can follow your instructions, but unfortunately when I reboot the options in System Preferences Screen Resolution, remain the same.

When I change the settings to

xres=1280
yres=800

and before I reboot is there something I have to do in Terminal to save the changes.

Thanks again
