Kamppeter, I'm not 100% sure how I managed to achieve this but you could try the following:
1)Disable one of the screens from displayconfig-gtk (a.k.a screens and graphics) 2) Go to terminal and do sudo gnome-display-properties 3)Choose the desired resolution Now when you boot up with the projector connected they should run on the same resolution (If they both support the resolution). As I said nothing in this guide is sure:) All I know is that I managed to make my external monitor and laptop to run on 1024x768 -- Cannot configure projector connected to laptop with Intel i915 (driver "i810") using displayconfig-gtk https://bugs.launchpad.net/bugs/151647 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
