New 10.04 install stuck at 800x600 resolution :(

[iridium21]

I've just installed Ubuntu 10.04 on an ASUS Terminator A7VT (onboard graphics) which is
connected to a 19" LG L194WT Monitor - the recommended resolution for this is 1440x900
but Ubuntu is only showing options of 800x600 & 640x480 and, as I'm sure you can imagine,
looks awful

This is my first time installing Ubuntu on a standalone machine (I've used it a bit under
Virtualbox) and I don't really know what to do next so any suggestions would be greatly
appreciated.

Thanks very much.

First you can try to boot from a Ubuntu CD (old and new) to
see if the resolution is higher when using a live-cd.
(which would indicate that you might get higher resolutions
by using a different graphics driver.)
If that is true compare the files /var/log/Xorg.0.log

The output of lspci (on the command line) should help
to identify the graphics chipset you have.
With the Vendor ID and the Device ID you might be
able to find more help for that specific graphics chipset.

Many thanks for the reply I really appreciate it.

When I booted from a a live 10.04 CD, Ubuntu was in 800x600 resolution with the only other option being 640x480.

The output of lspci is:

After searching about a little, I'm guessing that I need video drivers from here???:

http://www.openchrome.org/

But I'm not sure which drivers or even how to install them

Can anyone help please?

EDIT:

Or maybe something from here?

A little more info...

According to the Synaptic package manager the VIA Openchrome driver is already installed,
but when I go to hardware drivers it says that "No proprietary drivers are in use by this
system". I've even tried reinstalling them but it didn't help

Anyone?

EDIT:

And a little more info, although it looks like nobody can help me

I've just tried Linux Mint live and again the only 2 resolutions available are 800x600 & 640x480.

The file /var/log/Xorg.0.log will tell you which driver
is really used (vesa or openchrome or ...).

In case your system is using the driver for openchrome
you might try to change to a more generic one like
the vesa driver.
