[Bug 437173] Re: [GM45] [GT2+] Bad resolution choice for mirror mode with two 16:10 displays (ditto for 16:9)
What we've talked about doing in libxrandr-utils for situations that have differing aspect ratios would be to place black bars on one display so they can have similar effective resolutions. I think your concept fits with that idea generally. Moving this to the server for now since we don't have a package yet for libxrandr-utils. ** Package changed: xserver-xorg-video-intel (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Importance: Undecided => Wishlist ** Changed in: xorg-server (Ubuntu) Status: Confirmed => Triaged ** Summary changed: - [GM45] [GT2+] Bad resolution choice for mirror mode with two 16:10 displays (ditto for 16:9) + For mirroring, try to run one output at its native display, then scale the other ** Tags added: precise -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/437173 Title: For mirroring, try to run one output at its native display, then scale the other To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/437173/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry :( Used default of the intel driver: when booting a laptop with an external monitor connected, the default is mirror mode with a resolution that is 'biggest' one supported by _both_ monitors. (Compare: http://keithp.com/blogs/X_output_status_july_2008/) Problem: The visual impression is often (always in my experience) very bad: * external monitor often do not support the naive resolution of the laptop display * Even worse: first common resolution supported by both monitors has not the same aspect ratio as the displays Suggested solution for same aspect ratio: ...much better would be: If both monitors have the same aspect ratio (e.g. 16:10 or 4:3) choose the smaller resolution as the common base and scale to the size bigger monitor. (Because only one monitor needs scaling it should even save tons of GPU cycles. With the proposed algorithm, one output runs with the 'perfect' native resolution and only one is transformed, with taspect ratio is presered! Currently base resolution is: lower than min. of both display, _both_ are transformed, aspect ratio is not kept. At https://bugs.launchpad.net/bugs/437173 you can find lots of xorg.log and xrandr output. Lemme know if you need more other input.
