  • I have a dual-boot Acer Aspire AME600 with a monitor and an HDMI connection.   The case and Windows both describe the on-board driver simply as Intel (R) HD Graphics.  My montior allows for up to 1280x1024, but the driver is only allowing up to 1024x768.  I briefly tried Ubuntu 15.04 and have now dropped back to 14.10 and the Intel driver update, still with no luck at a proper resolution.

    1) How do I convince the driver that my monitor can support 1280x1024?

    2) When I have my TV turned on, how can I convince the system that the monitor still needs to be the primary display?

    Thanks!

  • What does xrandr say about the monitor? Sometimes it is possible to add a mode by hand (by calling xrandr) for a display even if the display has not claimed it is capable - I've successfully driven some at higher resolutions than they report that way.

    As to the second question - that's kind of down to your desktop environment - there should be a section for configuring "displays" in the Unity configuration (or Gnome or KDE or XFCE or MATE or whatever you are using), and you can usually choose how extra displays are handled there.
