    Phoronix: Per-Session Display Configuration For Mir Has Landed

    We know that a lot of Mir improvements/features should land this week with the Ubuntu 13.10 feature freeze being imminent. The first Bazaar commit this week to the Mir Display Server has added in support for per-session display configuration...

    This means that the desktop resolution will come back to normal when, for example, a game set to a custom one crashes?

    If I understood correctly, that's awesome

    I *think* Wayland already have a similar mechanism, so it's great those problems will definitely die with X.

      One of the most annoying problems in X... Do you know the name of that feature in Wayland?

      Obs.: It is very good Mir corrected this, just imagine you with your Ubuntu Edge and by some reason a game crashes and you cannot see the complete menu to adjust a new resolution :O

        Thank God!

        It would be a disaster on a mobile if the screen resolution was screwed up. It would be impossible to fix the problem with such a screen resolution dependent interface. How does android deal with this problem? Similar to the Mir/Wayland method?

          Who cares about what Mir does? It's just going to fail and be replaced with Wayland eventually, when Canonical notices that no one wants their display server, and it's way too much trouble to maintain than they are capable of...

          Right now, they're just too invested in their little pet project, they've hyped it so much that they can't back out now without "losing face" (or hurting Shuttleworth's ego), so they have to stick to their guns, hope the noise dies down, and later on quietly move back to Wayland with their tail between their legs... Wayland will be used by everyone else, and Ubuntu will eventually be forced to follow suit in order to even remain relevant.

              See what happened with Upstart.

                I don't think it lets applications change the resolution. It doesn't even let users change it without root.

                  It got picked up by RedHat and Oracle the too biggest Linux server companies in the world?

                      look how they're staying away from systemd you Think they will use Wayland? (Btw systemd will most likely be needed for Linux down the road)

                        RedHat is moving to systemd, and Oracle will follow suit because they base their distro on RHEL.

                        Regardless, Upstart is hardly comparable. It's just an init system, and having a different init system rarely if ever affects compatibility of applications. The same cannot be said of a display system (except if we're talking about CLI applications). Mir will end badly for Ubuntu, they will be forced to at the very least implement client-side compatibility with Wayland - which would effectively make Mir another Wayland compositor. At that point, no one will bother maintaining Mir support, even if they did at that point (which is already unlikely) and eventually, Ubuntu will just quietly phase out the Mir API and just use pure Wayland only.

                        It's just a shame for all the damage they'll manage to do in the meanwhile.

                          display system's login's Etc will use systemd as well

                            They can, they don't have to. There's nothing in the Wayland protocol requiring you to use systemd, it's up to DE's to decide if they want to have hard dependencies to systemd, and Canonical could well implement a Wayland compositor that is compatible with Upstart.

                              The Systemd project became a kind of large ecosystem which is (ironically?) not dependent on the core Systemd.


                              For example, the following services are installed and used by default on Ubuntu (at least on 13.04) :

                              systemd-hostnamed
                              systemd-localed
                              systemd-logind
                              systemd-timedated

                              These all work perfectly on Upstart.
                              (not to mention udev)
