I just upgraded to 11.10 from 11.04 Desktop overnight.
The main problems were that on reboot, I would get the following:
Black screen after the Ubuntu graphical progress screen
Failed to connect to socket /var/run/dbus/system_bus_soscket: Connection refused
Waiting for Network... (and for another 60 seconds)
On booting to the recovery menu, blank screen
On figuring out to change the vga mode on the recovery boot command, and finally getting to the Recovery Menu, my USB keyboard did not work, so I could not navigate the Recovery Menu
My top priority was to at least be able to log in.
Here are the steps I had to take. Maybe they will help some of you. The list includes every step, even some that might be obvious to experienced users.
Hold down SHIFT on boot to enter the GRUB menu.
Highlight the entry labeled "recovery".
Press 'e' to edit the boot commands.
Find the line starting with linux...
Edit that line to change "recovery" to "single" (this boots directly to single user mode as root, rather than the no-keyboard Recovery Menu.
Edit that line to change the vga parameter to match your screen's resolution (mine is 1400x900, so 867 [see Wikipedia "VESA BIOS Extensions, Linux video mode numbers]).
Press F10 to boot. This brought me (finally!) to the root prompt.
cd /var/run/dbus
rm pid (assuming you had the dbus error message).
Reboot.
After all this, I was able to log in to the graphical desktop of 11.10.
So the root cause was the leftover pid file, but getting to a prompt to be able to remove it was a CHORE.
I may still have some other clean up to do, but at least the scary can't-boot problem seems to be resolved
