Upgrade from 9.04 to 10.04 then 10.10 on kid PC

Upgraded to 10.04: no problem but as previously, out of the box it doesn't work with the Nvidia Geforce2 MX200 that's plugged in. Couldn't find the way to enter safe mode so I removed the Nvidia card and plugged my old CRT monitor to the internal VGA port. Reboot: OK, I've got a screen to use the system at least.

So I'm now running the 10.04 to 10.10 upgrade.
