I have an old laptop that I installed Ubuntu on from Windows XP previously. After the installation I noticed the screen resolution is wrong and not all of the screen fits on the display.

After researching this, I have ran: lshw -c video

and obtained the following output:

*-display UNCLAIMED     
   description: VGA compatible controller
   product: 771/671 PCIE VGA Display Adapter
   vendor: Silicon Integrated Systems [SiS]
   physical id: 0
   bus info: pci@0000:01:00.0
   version: 10
   width: 32 bits
   clock: 66MHz
   capabilities: vga_controller cap_list
   configuration: latency=0
   resources: memory:c0000000-cfffffff memory:d4000000-d401ffff ioport:9000(size=128)

I am a complete newbie to Linux/Ubuntu and not sure what to do to fix my display. After I fix the ability to see things correctly, I hope I can learn the system more easily. As such, any help would be gratefully received to help me get past the first hurdle.

Crudly, I think the problem is simply that I do not have the correct graphics driver for the system and need to upgrade/install one. Problem: which one and how?

I never had this problem when the laptop ran Windows XP.

Thanks

First maybe try to "Detect Display" in GUI in top right corner icon go to:

Goto Ubuntu Menu: System -> Preference -> Display

If this autodetection does not work I suggest you to read Wiki page https://wiki.ubuntu.com/X/Config/Resolution#Dynamically_testing_different_resolutions

Here you see xrandr command and some examples like:

xrandr --output VGA1 --mode 1024x768 --rate 60

BTW You should also mention which Ubuntu you are using as from version 13 they got new GUI.
