    initial resolution issue - xrandr false detection of second monitor

    I updated 13.04 today and ended up with two issues:

    1. On reboot two monitors were 'detected' though I only have one.

    2. The initial resolution was improperly detected.

    ----

    1. I was able to 'deactivate' the second monitor

    2. After disabling the second monitor I was able to set the proper resolution -- however each boot results in the wrong resolution at the login screen... after login I get the proper resolution.

    ----
    I searched launchpad and did not find any related bugs so I thought perhaps I was the only one to have experienced this issue -- anyone else? If yes, can someone point me to the bug report.

    ---- update ----
    I did some more digging myself and I am seeing the following results:
