Yeah, that's a good point. This affects the Flashback mode as a whole...
Another possibility will be to drop gnome-session-f{lash,all}back packages from
gnome-panel source. This way we won’t need to remove stuff that depends on
gnome-panel (though I still do not like this, see below).
I think the best solution will be to leave things as-is. But if you convince
the Release Team that removing 10 packages (or backporting 800 lines of code
to add keyboard grabber) is a good idea, I will be fine with that.
I don't think this is fit for release as-is.
Are you referring to the two patches I posted? If so, I wish it was that
simple; those a) are a hack, since they provide org.gnome.Shell, b) only
fix media keys custom keybindings, not layout switching/input sources,
c) even for media keys, there is no OSD, for e.g. volume.
Yes, I am referring to the two patches you posted.
Note that gnome-flashback already owns org.gnome.Shell to show end session
dialogs.
In any case, though, let's agree on the problem first. This is currently
a severity: grave bug, i.e. release critical.
I agree that this is a problem. However, GNOME Flashback can still be
usable in most cases:
- To switch keyboard layouts one can use good old xkb (I do that when I use
GNOME Flashback session).
- Other keybindings are not so critical. To lock screen / power off / etc
one can use the user menu.
Thus I still think this bug should be downgraded to important or ignored for
Jessie.
This mail is written from gnome-flashback session on Jessie, btw.

Bug#771922: keyboard handling broken with jessie's gnome-settings-daemon
Package: gnome-flashback Version: 3.8.1-7 Severity: grave Hi, First of all, there's a number of severity: normal/important bugs reported against the gnome-ssession-fallback package that mention keyboard shortcuts issues (#727047, #730831, #731245, #731418, #727046, #730096). My investigation shows that are partly related to each other but in aggregate indicative of a more serious issue, hence this new severity: grave super-bug. Apologies for the extra spam, feel free to merge if you think that's better. Second, I'm far from a GNOME developer or expert and the information below is just the result of a day's investigation into GNOME's code, bug tracking system and git history. Take everything I say with a grain of salt and please double-check :) So: the following things are broken in GNOME Flashback mode in today's jessie: 1) Keyboard layout switching 2) Non-metacity (i.e. g-s-d) keyboard shortcuts (e.g. Ctrl+Alt+L to lock screen) 3) Custom keybindings as configured by the control center 4) Power keys 5) Media keys (volume, play/pause) I think that at least (1) (2), as well as the combination of all these (plus the unrelated #734822, which is fixed by gnome-flashback 3.14 as found in experimental) makes the package unusable for most users and hence unsuitable for a release with jessie. The cause for this seems to be a general upstream trend of moving off functionality from gnome-settings-daemon and into gnome-shell. This became an issue in Debian with the inclusion of GNOME 3.14 in jessie. Upstream g-s-d commit b0cee1df30b4945f524611f354ff164d4a383262 (media-keys: Refer key grabbing to the shell, BZ #693016) removed media keys support, 326ee9f9a102a58941473e08fbe6221e70369f7f (keyboard: Remove input sources handling, BZ #736436) removed input source switching support and finally 66c975cd90736e32f20ffd36846301d68e7a08e7 (common: Remove unused keygrab code) removed the keygrab code entirely. There's a number of other commits that touch e.g. media-keys code too. This is deliberate, as GNOME proper doesn't really care about Flashback at this point. gnome-flashback's upstream is aware and trying to fix those issues in Flashback it self. Current master has cfce8742780e8be335cf19dd49a993cc0ea63b13 (libkey-grabber: initial version) the very hackish 670c310e8eaf89e895da96e62edc2a724c4ec068 (own org.gnome.Shell, see BZ #739534[1] for why this is very hackish and also indicative of GNOME proper's attitude to Flashback :/). I backported both of the aforementioned two commits to both jessie's and experimental's gnome-flashback (the former needed a bit of a porting work, the latter applies cleanly). Media keys custom keybindings functionality was restored, albeit without an OSD; keyboard layout switching was not, however. All in all, I'm not sure what the proper solution would be -- I'm hoping that you, as maintainers, may have a really bright solution :) As I see it, deviating significantly from upstream and reverting big g-s-d commits doesn't sound like a great strategy to me, especially this late in the jessie cycle. I think the most sensible approach at this point would be to get in touch with Flashback upstream and figure out the remaining bits (input sources, media keys, OSD). Then, stack patches against Flashback 3.14 (not 3.8) and beg the release team to make a big freeze exception on the basis that the alternative of removing Flashback from jessie entirely would be a big regression from Wheezy. Doesn't sound to me like something that has many chances of success, but Flashback is fairly self-contained and might be considered important enough. Let me know if you need any further clarifications or help from me. I'm pretty bummed at this point.
