I used the same 12.04 install disk to install on two desktop machines. One worked correctly and easily recognized the Dell 2210 display. The other loaded an LTS (laptop??) version that has a display driver that insists it's on a laptop with all the wrong resolution options. Reloaded again and couldn't find any way to force loading the desktop version. how do I fix this?
LTS stands for Long Term Support. Ubuntu 12.04 is a LTS release (meaning: it would have longer support and other candies) and it does not mean that you'll get laptop display drivers installed.
