[Launchpad Bug Tracker <349943@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

Hardware: Asus F8Va laptop (Core 2 Duo P8600, ATI HD3650, 1440x900)
OS: Ubuntu 9.04 beta x64 (Wubi installation inside Windows Vista Home Premium x64 SP1)

External monitor (Samsung SyncMaster 2493HM, 1920x1200), connected via HDMI, blinks several times a minute, randomly. When there is no user activity, it doesn't seem to blink however.
By "blinking" I mean, the monitor goes off and then on, like it usually does when it changes resolution, only resolution doesn't change. Also, when I move windows around, thin horizontal stripes flash in fraction of second from time to time (only on external monitor).

Screen configuration:

Samsung 24": On
Resolution: 1920x1200
Refresh rate: 60 Hz
Rotation: Normal

Laptop 14": On
Resolution: 1440x900
Refresh rate: 67 Hz
Rotation: Normal

Mirror screens: unchecked

Relative position of screens (physical and in Display Preferences)
laptop screen below the external screen, centred.
