Cannot set up dual screens with "extended desktop"

[Phill]

Binary package hint: xorg

Using 10.10, I cannot "extend my desktop to a second monitor" (in windows speak) I used to be able to do this with 10.04!

Start Monitor Preferences from System->Preferences->Monitors
Uncheck "Same image in all monitors"
Click Apply, or Click Make Defualt
A Dialouge box pops up stating "Please log out and log back in again"
Click ok on the Dialoge box
Log off and then back in and both monitors still have the same image.
Repeating the steps again does not rectify the problem.
Restarting does not make any difference.

I have managed to get it working now, the only way I could get it to work was by connecting the second screen after Ubuntu had started. I still had to log out and back in again 3 times though!

Hey phill,

Hi, have you had a chance to test if this bug is still present in natty?

If it does (and if you're the original reporter), please boot into natty
and run the command:

  apport-collect <bug-number>

which will update the bug with fresh logs and tag the bug as affecting
natty. (It is best to run this right after reproducing the problem.)

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
