I understand that Unity 2D is more accessible, but I don’t know how to switch to it. I’m wondering if someone can explain how to switch the desktop, and how to make it accessible as possible, as I use the system as a home server.

Ok, here is a command that should change your session to unity-2d, without you having to log out and stop lightdm. This should worok 100%.

You need to know what your user ID is, not your user name your user ID number. To find this out, open a terminal and run:

echo $UID

Make a note of the number you hear, you will need it in the next command. To make the change, run this command:

dbus-send --type=method_call --system --reply-timeout=1000 --dest=org.freedesktop.Accounts /org/freedesktop/Accounts/User$uid org.freedesktop.Accounts.User.SetXSession string:ubuntu-2d

Where $uid is your user ID number, mine is 1000.

accessibility at login will certainly be fixed for precise, and may be fixed in oneiric as well, depending on how invasive the fix is.

Hope this helps.
