Hopefully this information can help a little. I tested this on my laptops HDMI port using an HDMI -> DVI converting cable.
If I plug the HDMI cable in before I turn the computer on, the laptop recognizes both screens and I can manipulate them (not with the hotkey still). I can go into System -> Preferences -> Monitors and turn each one off, adjust the resolution, etc. The monitor's picture was a little blurry, but I'm not sure that it's related to this problem. However, if I shut the machine down, unplug the HDMI cable, and boot up the original problem persists. It sees the monitor, and even if I turn it on / off, no picture appears on the monitor's screen. -- External display not working https://bugs.launchpad.net/bugs/533269 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
