I just applied your patch efl-1.22.4.
It works.
Thank you.

I removed the patch, I have an infinite loop that appears at the launch of applications, when starting E.
On the other hand the virtual keyboard is visible on lightdm.

Do you have a test case for this?

Hm the modified patch you've posted here seems like it is broken according to wm specs; the issue is that the window should be waiting for the wm to configure it once it is shown, but you've subverted that by toggling the configured flag if the environment is a compositing wm (and added a roundtrip to every event).

I'm testing here with the latest EFL from master (rEFL3932c6838292472b14f6dcfd90e74c59554c9524) and this patch applied on top: things seem to work as expected in Enlightenment 0.23 as well as other WMs. I'm wondering if this is an issue with the 1.22 branch somehow...

I have a few things to finish, then I will wear the top version of the EFL-1.23.xxxx,
I tell you that quickly.

I've just tested on 1.22.4 and it does indeed seem to fail there. Will examine this a little more...

Hm after quite some time looking into this, I've run out of time. There's some sort of X11 protocol handling race condition which triggers under enlightenment/efl in 1.22 but is resolved in 1.23. I'll skip backporting this, but it does seem to fix the issue in 1.23.

Ok, I test the efl 1.23,
Thank you

@thierry1970 hey, with the patches I've just added to this series everything should be fixed even in 1.22.

@zmike, I just applied the patches (D10012, D10013, D10014, D9899 and D9900) on efl 1.22.5.
E does not panic and the keyboard works under ligthdm.
Congratulations for the work!

Great to hear!
