In the log in screen, top-right corner of the screen, the accessibility button is there, but its icon is missing. A placeholder image is shown instead.

bug#57292: GDM accessibility menu buttons don't do anything

[Maxim Cournoyer]

Hello Guix!

I've just noticed that the accessibility buttons at the top right of the
screen, e.g. "High Contrast" don't stick in the enable position, and do
seem to do anything.  Both in 40.1 and the 42.0 I'm about to update to.

Thanks,

Maxim

Hi Maxim,

I think the issue is that the accessibility bus is not, uh, accessible.
In particular, the following line appears in GDM's greeter log:

(gnome-shell:767): dbind-WARNING **: 20:29:48.718: AT-SPI: Error
retrieving accessibility bus address:
org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was
not provided by any .service files

Note that the service itself is provided by at-spi2-core.  Perhaps we
should wire things up in gdm-service-type?

Cheers

bug#57292: [PATCH] services: gdm: Add packages for accessibility settings.

[Dariqq]

gdm needs the "/share" subdirectory of these packages present in XDG_DATA_DIRS
such that the accessibility settings work:
- gnome-control-center: For the icon.
- dconf: To be able to change settings.
- at-spi2-core: contains accessibiltiy dbus-service.

* gnu/services/xorg.scm (<gdm-configuration>)[gnome-shell-assets]: Add
at-spi2-core, dconf, gnome-control-center.

Since this is, as the name implies, intended for artwork or other
non-functional "assets", perhaps these package should be propagated by
the gdm package itself?  Would that have achieve the same?

This issue appears to have been discussed previously, although I can't
find it anymore...

That's what I tried initially and confirmed again today that it doesn't 
work for both inputs or propagated inputs. (the icon from 
gnome-control-center is visible because the share directory will be 
included XDG_DATA_DIRS from the wrapper script from the glib-or-gtk-wrap 
phase but not he other packages).
After that the next most simple solution was the hacky workaround via 
gnome-shell-assets. Maybe someone has a better idea for how to include 
the extra packages?


Also as I use the gnome-desktop via gnome-desktop-service-type all these 
packages should already be in my system profile. So somehow the 
environment is weird when shepherd starts gdm such that gdm can't find 
the extra files but I don't know enough of both guix/shepherd and 
gdm/gnome to figure out what the exact problem is.

I found https://issues.guix.gnu.org/28088 which is a bit related but not 
exactly the same as there is no login manager involved.

Ah, that's interesting.  It means there's probably some environment
variable that gets set and usefor the other things too, or perhaps it
searches relatively to its binary.

Ideally we could patch what it needs in the gdm package definition.  A
second option would be to wrap GDM with the paths such as XDG_DATA_DIRS
it wants.

Thanks, that's the issue I remember seeing.

I'd like to avoid abusing the gnome-shell-assets, so would welcome us
further investigating the sources of GDM to get clues as to what/where
it's looking and what it wants exactly, but otherwise with your
explanation I think this can be a first step (apply this change as is).

Does anyone have a problem with it?

Currently gdm starts with XDG_DATA_DIRS set to the share directories of 
gnome-shell and all packages in gnome-shell-assets.

Looking at other login-managers it seems they also set XDG_DATA_DRIS 
explicitly. Specifically the sddm-shepherd-service seems to solve this 
by setting XDG_DATA_DIRS to the correct path of the current system 
profile i.e. "/run/current-system/profile/share".

Maybe we could do the same with gdm? We then would need to add the extra 
packages to the system profile rather than some wrapper.


This will then work work for a gdm+gnome setup (with empty 
gnome-shell-assets) as the gnome package propagates all the packages 
needed and more.


For gdm-only there is then a problem how to include the extra packages. 
Currently the gdm-profile-service extension only adds the 
gnome-shell-assets but now also gnome-shell would be needed as this 
currently not in the system profile but added in XDG_DATA_DIRS.

Then there is the question whether the extra packages should be added to 
the profile by the service or propagated from gdm (or some other 
package). If the answer is gdm then gdm would also need to be added to 
the profile and as gdm depends on gnome-shell and want's gnome-shell 
present a service would need to add gnome-shell anyway.

This is essentially the same as the current solution via 
gnome-shell-ssets but this will work if the extra packages are in the 
system profile through any mean (and not explicitly added via the 
gnome-shell-assets) however for non-gnome-setups using gdm a solution is 
needed in any way.

bug#57292: GDM accessibility menu buttons don't do anything

[Dariqq]

hi,

the patch that i've just sent fixes the missing icon and functionality 
(on gdm 42.0, have not tested gnome-team branch). I've also added the 
at-spi2-core package discussed before. With this gdm logs that the 
org.a11y.Bus and  org.a11y.atspi.Registry service are started.

However there is a new warning later:

ATK Bridge is disabled but a11y has already been enabled.

I don't really how this dbus service works and if this a problem.


At least the basic stuff like zoom, big text, etc. work. Also I've been 
unable to verify that the screenreader/orca starts in the gdm menu 
because sound is not working on my machine.

bug#57292: [PATCH] WIP: gnu: propagate inputs for gdm and rework gdm-service-type.

[Dariqq]

* gnu/packages/gnome.scm (gdm)[propagated inputs]: Add adwaita-icon-theme,
dconf, font-abattis-cantarell, gnome-control-center.
* gnu/services/xorg.scm (gdm-shepherd-service): Set XDG_DATA_DIR to
run/current-system/profile/share.
(gdm-profile-service): New variable.
(gdm-service-type): Use gdm-profile-service.
(gdm-configuration-gnome-shell-assets): Set default to gnome-shell.

Hi Maxim and others,
This is not quite the explicit wrapper we talked about on IRC but something similiar.

The gdm package now propagates the packages from gnome-shell-assets and I added dconf and gnome-control-center for basic accessibility settings functionality + icon. Does this introduce a problem as dconf is already a natice input?
Maybe also some other packages can be added like  at-spi2-core, orca, ... or is this something the user should add to the system profile themselves?

In order for the gdm-shepherd-service to find the propagated packages I changed the XDG_DATA_DIR of the service to the system profile and added a gdm-profile-service to add gdm and gnome-shell to the system profile. Probably the gnome-shell-assets name should now also be changed as is is now only the gnome-shell package.

What do you think?

In my opinion, adding gnome-shell and gnome-control-center to gdm-
configuration-gnome-shell-assets would be preferable to propagating
inputs.

WDYT?

This is basically my original patch in https://issues.guix.gnu.org/57292#3.

If i understand it correctly Maxim wants gdm to take care of all of 
dependencies providing functionality and handcrafting the environment 
with gdm-shepherd-service and gdm-configuration-gnome-shell-assets feels 
like a hacky workaround.

Yes, it seems Maxim and I have conflicting goals.  Maxim wants to avoid
"abusing" gnome-shell-assets whereas I want to avoid propagation, as it
pollutes profiles.  Perhaps Maxim and I can agree on how to interpret
gnome-shell-assets, as IIUC even with packages that aren't "pure data"

We should do so especially because the newly propagated variables are
anyhow propagated by gnome-desktop-service, which could constitute
weird behaviour all around.

What would you think of the wrap-program solution which would avoid 
propagating pacakges?

I currently have something like

#+BEGIN_SRC scheme
(add-after 'install 'wrap-gdm
             (lambda* (#:key inputs outputs #:allow-other-keys)
               (wrap-program (string-append #$output "/bin/gdm")
                 `("XDG_DATA_DIRS" ":" prefix
                   #$(map (lambda (input)
                           (file-append (this-package-input input) 
"/share"))
                         '("at-spi2-core"
                           "dconf"
                           "gnome-control-center"))))))
#+END_SRC

Also this way the assets (adwaita and cantarell) should be kept in the 
gdm-configuration as when I tested this I had a white box as a cursor.

That SGTM, but we do need a more descriptive phase name.  The question
is whether we should inline the gnome-shell assets this way as well or
not.

Maxim, WDYT?

I have never attempted to customize gnome-shell.  If it can be
customized with custom themes, different fonts and what not, then I
think it makes sense to keep the user-choosable art assets as
gnome-shell-assets.

Otherwise, if it's not configurable and expects only a specific font,
specific icons, etc., then it seems it'd make sense that it finds them
out of the gate (wrapped from within a phase).

Could someone confirm whether GDM is configurable when it comes to icons
and fonts?

Thanks for working on it, Dariqq!

Without the context of Guix, it is.  Within the context of Guix, we'd
have to make gsettings functional for most (all?) changes to have an
effect.

I tried in a vm with only gdm-service-type (and no gnome) and the assets 
also wrapped inside gdm and got a white box as a cursor. This might be 
caused by adwaita not being in the profile (which gnome-shell-assets 
also get added to) but I am not sure about this.

I'd suggest leaving the gnome-shell-assets as is for now and deal with 
the gdm customisation issue at another time as it looks like it is more 
complicated than just adding the assets to the wrapper.


Regarding the patch should I create and send it or someone of you? (I 
don't really care)

And if the answer is me should the patch be against master or gnome-team 
branch?

As Dariqq tried to inline the assets in the wrap phase and that did
*not* immediately, work, and since in theory a user could configure GDM
to use different assets, I think the art assets can stay where they
currently are, and the above patch merged to master to fix this
longstanding issue.  Perhaps the phase name could be
'wrap-accessibility-dependencies'.

Dariqq, if you send an updated patch along these lines, I think we can
finally get it merged.

bug#57292: [PATCH v3] gnu: gdm: Enable accessibility settings.

[Dariqq]

gdm needs the "/share" subdirectory of these packages present in XDG_DATA_DIRS
such that the accessibility settings work:
- at-spi2-core: contains accessibility dbus service.
- dconf: To be able to change settings.
- gnome-control-center: icon.

* gnu/packages/gnome.scm (gdm)[inputs]: Add at-spi2-core, dconf, gnome-control-center.
[phases]: Add wrap-accessibility-dependencies phase.

Change-Id: Ibfe8f1aee9c8fe0c06f895de121f0f84defe4773
---

Hi everyone,

Here is v3 of gdm accessibility issue which adds the wrapper phase we've been discussing.
I added the extra inputs under a seperate section in the inputs. If you'd like to keep them in alphabetical order feel free to adjust this. 
ALso I am not sure if the format of my commit message is ok.

I've tested on both master and gnome-team and it works on both.

To ennable the screenreader it is enough for orca to be in the system profile (and orca working i.e. on gnome-team branch).
dconf is both a native and normal input: Based on the fedora gdm.spec it seems like a build dependency however i was not able to verify this as cross-compiling (for i686-linux-gnu) requries me to bootstrap gcc. At leeast the default tests do not seem to require it.
Adding gnome-control-center, which is used for the icon, pulls in python dependencies which breaks cross compiling. Maybe you have some ideas for this.

Also some other thing that I notices is that because /var/lib/gdm is mounted as tmpfs this makes the changes in the gdm accessibility settings not persist through reboots which is annoying. These will get stored in /var/lib/gdm/.config/dconf/.

I've rewritten the commit message slightly and pushed this to gnome-
team.  Thus closing.
