I have been working to make it possible to navigate the gdm2 login screen.
However, the work is not completely done, and may not be usable for your
To use the work-in-progress, you need to use gdm2 release 220.127.116.11,
which is very recent. You will notice that this version of gdm2
supports the AddGtkModules and the GtkModulesList settings. By turning
on the gesture listeners you can cause certain applications (such as
Gnopernicus, Gok, etc) to be launched when a gesture (such as a certain
hotkey combination) is pressed. Note that the gesture listeners only
work with the "Standard Greeter" and not the "Graphical Greeter".
The main problem is that the "light window manager" that runs with the
"Standard Greeter" is missing some needed functionality that would get
in the way of running various AT programs that have GUI's. For example,
the light window manager does not support switching window focus via
keyboard navigation. Also, the light window manager doesn't support
window move/resize, which might also be a problem in certain situations.
Lastly, the various AT programs might require some enhancements in
order to be usefully launched at login time. Since the gesture
listener mechanism launches the AT programs via a command, it would
obviously be useful if the AT program allowed you to launch it in
the appropriate mode with command line arguments (rather than having
to go into the configuration and setting preferences). However, some
AT programs may not allow themselves to be launched via a command
line in this way.
Anyway, you can play with this by following these instructions (assuming
you have gdm2 release 18.104.22.168 installed and running on your system):
Note gdm_sysconfdir = gdm_install_dir/etc.
To enable accessibility:
+ Edit (gdm_sysconfdir)/gdm/gdm.conf
Set the key "AddGtkModules" to "True"
Set the GtkModulesList to include all the accessibility GTK_MODULES
that should be launched (it should already be set to the following
by default so you should not have to change it):
Note that if you have your gtk-modules installed to a nonstandard
location (somewhere other than /lib, for example), then you may need
to specify the full path of the library in the GtkModulesList. In
other words, it might need to be specified like this:
+ The gesture listener configurations files need to be edited to
define the gestures that will be listened to :
Both files includesextensive comments describing how to set up
+ Now, you should restart gdm2 by running sbin/gdm-restart, and
when you enter the gesture, the AT program should properly
Let me know if you need any further information.
