I have made some search in internet how to install Ubuntu in a Toshiba Portege M700.
After some work, I do have an Linux Ubuntu system in Portege M700 with full graphics working, pen perfectly installed (with rotation as well), network (wired and wireless) and functional DVD-RW driver.
Modem and sound need extra work.
I have not tried the other devices.
The abstract of my work is here
