System compositor input events passed to console (particularly troublesome for Alt+Fn and Alt+Left/Right)

[Robert Ancell]

When using Mir as a system compositor it doesn't set the VT to KD_GRAPHICS mode so all input events are passed to the console.

[Alan Griffiths (alan-griffiths)]

Lacks context.

Is this addressed by lp:~alan-griffiths/mir/Add-MIR_DISABLE_INPUT-feature?

[Chris Halse Rogers (raof)]

No. It's also not (exclusively) a Mir bug, but is here to simplify not leaking private stuff.

To bulk this out - in system-compositor land, circa 13.04, we'll be entirely ignoring Mir's input stack and having all the X servers talk directly to the input devices. This means we get a fully functioning, tested, input stack without significant effort, but means that all clients of the system compositor get all the input, all the time.

Thus, we need to get XMir to cooperate with switching - XMir needs to know when it loses system-compositor focus and release the input devices. Then, XMir needs to know when it gains system-compositor focus and to acquire the input devices.

There's also the fact that Mir doesn't set the VT to KD_GRAPHICS mode, so the kernel also handles everything you type (which is why hitting Alt-F4 under Mir will VT switch)

I'll add to the troublesome combinations, I can't use ctrl+shift+u+<code> to print unicode characters.

Fix committed into lp:mir at revision None, scheduled for release in mir, milestone 0.0.9

[Launchpad Janitor (janitor)]

This bug was fixed in the package mir - 0.0.8+13.10.20130808.1-0ubuntu1

---------------
mir (0.0.8+13.10.20130808.1-0ubuntu1) saucy; urgency=low

  [ Robert Ancell ]
  * VT switch on alt+ctrl+Fn.
  * Add missing iostream import. This was accidentally removed in
    revision 939. Local builds and CI builds both seem to have treated
    this as a warning; debian package builds as an error. Fixes
    packaging builds.

  [ Robert Carr ]
  * Add an interface by which the shell may be notified of and interfere
    with surface configuration requests.

  [ Alexandros Frantzis ]
  * Bring back revision 931 with a fix for the crash it caused (LP:
    #1209053). (LP: #1209053)
  * examples: Quit the example servers and standalone programs when
    Ctrl+Alt+Backspace is pressed.

  [ Maarten Lankhorst ]
  * Re-introduce console support, and ignore control characters. (LP:
    #1102756, #1195509)
