Uninstall via driver/install openchrome driver

[modokalle]

I'm quite new to linux.
How do I uninstall a driver and install a new one? For example:
My computer (Fujitsu-Siemens Amilo Pro 3515) includes a Via graphics module (VT8237, Chrome9 HC IGP). I want to have better display resolution than 800x600. I suspect I need to install other drivers, in this case from openchrome. When I try to install them, I get the message
"conflicts with the installed package xserver-xorg-video-via".
How to make this not happen?

Re: Uninstall via driver/install openchrome driver

They are excluding options: either you use xserver-xorg-video-openchrome or xserver-xorg-video-via.

xserver-xorg-video-openchrome tells:

Replaces: xserver-xorg-video-via, xserver-xorg-video-unichrome
Conflicts: xserver-xorg-video-via, xserver-xorg-video-unichrome

How do I uninstall a driver and install a new one?

If you install xserver-xorg-video-openchrome =>
Synaptic (i'm using) package manager will tell:

Mark additional required changes ?
The chosen action also affects other packages. The following changes are required in order to proceed.

To be removed
xserver-xorg-video-all
xserver-xorg-video-via

OK ?

Note
xserver-xorg-video-openchrome tells:

This driver is originally shipped to be loaded as 'via' on xorg.conf, but this
package renames it to 'openchrome', so it doesn't conflicts with the other VIA
driver already available on Ubuntu.

=> you need to edit xorg.conf (Driver "via" -> Driver "openchrome")
or you need to run

sudo dpkg-reconfigure xserver-xorg

Here is good page of sudo dpkg-reconfigure xserver-xorg:
