Public bug reported: My external Citizen monitor is not configured automatically anymore, when it did when Precise was beta and in prior stable releases.
Gnome Display pane lists the monitor as unknown, and lists the following resolutions. 1024 x 768 800x600 The monitor works with the lower res setting for seconds at a time, like a strobe light. The higher resolution makes the screen go black with the odd white pixilated streak. Popping over to tty1 shows the following errors flooding the screen in non-stop intervals while creating synchronous lagging in responsiveness. unknown citizen ramdom dvi detect error probed a monitor but no|invalid EDID EDID checksum is invalid ,remainder is 146 Hardware First generation (2006) Intel MacBook Pro (Intel Core Duo, aka Yonah based processor) with an ATI Mbility Radeon X1600 video card.
