If your 2086 is a vintage model then it is worth checking with Amstrad for an upgrade to the mouse driver.

And for many Linux distros some part of the Integration services (such as the mouse driver) does not work.

But presumably I can put a mouse driver in later?

And your mouse driver still doesn't work!

I think that's the old mouse driver.

You didn't load your mouse driver?

So we haven't got a better mouse driver.

So a real mouse driver somewhere?

Reboot it, start Windows without running your mouse driver, see if Windows will run it itself.

It could also be used as a mouse driver.
