Kubuntu 11.10 downgrade xorg

[IanWood]

Hi,

I have just installed Kubuntu 11.10 on my work machine with a Matrox card in it and as I feared the Xorg is too new for the driver.

I also use 10.04 and that Xorg works.

How do I downgrade the new Kubuntu's xorg to the same one as used by 10.04?

Thanks in advance,

Ian
