because https://phab.enlightenment.org/D12143 is merged

@bu5hm4n Sure, I am OK with that

Yeah I posted the raw diff. Let me figure out what I can do

https://phab.enlightenment.org/D12143

Now that's from 2013, so I think lots have been added to logind since then.
All I needed to do for EFL (so far haven't tested yet) is a ~40 line patch. (did something similar to wlroots and getting reviewed for Weston)

@raster CONFIG_VT=0 is probably something that would be considered in the far far future TBH since most kernels have it enabled, but I guess it's best to remain prepared...
It's a compile time option to disable the virtual terminals. There was lots of talk about it in 2013, https://dvdhrm.wordpress.com/2013/07/08/thoughts-on-linux-system-compositors/

Yeah, Never mind I think It's a Debian issue

hang on, that is odd, I did not realize the file is not there on my chroot

apt-file search /usr/include/linux/dma-buf.h
linux-libc-dev: /usr/include/linux/dma-buf.h
ls -l /usr/include/linux/dma-buf.h
ls: cannot access '/usr/include/linux/dma-buf.h': No such file or directory

...Let me add debian-backports...

OK. Let me know if you need a QEMU configuration, that has the ability to support multiple seats, or a bash script to make it easier to configure your udev for multiple seats , if you need to experiment with multiple seats, because I have that if needed.

I updated the diff
I don't know if ...is it valid for the first argument of ecore_drm2_device_open to be NULL? (assuming it is running on seat0 , otherwise it won't work)
because if it is this might be an API break compared to the last one I submitted...

Add EINA_SAFETY_ON_NULL_RETURN_VAL(seat, NULL) check

Is there something I need to change with this?

I am looking at https://git.enlightenment.org/core/efl.git/tree/src/lib/ecore_drm2/ecore_drm2_device.c?id=0d845ce3aa88738e5313d81745f882e011333204#n144
...maybe I'm wrong, but it looks like chosen_dev only gets set if the parent device is PCI, (so I don;t know how that works with DisplayLink devices)...

Hm... ...I don't know what the second if statement was for...
...at first I thought that in case if dseat was NULL (in case if the seat attribute was not set in udev)

Yes. I submitted something upstream to Weston. As of now ,unpatched Weston fails to start on non-seat0 as well
https://lists.freedesktop.org/archives/wayland-devel/2017-December/036433.html

I can start bash on seat1 with

This is fallback for if there is no boot_vga video device. (not that there's no video device at all) It's preferable to use it, but according to Weston, there's only one on a system
https://cgit.freedesktop.org/wayland/weston/tree/libweston/compositor-drm.c#n3730
so it's not guaranteed to be assigned to the seat.

Do you mean
EINA_SAFETY_ON_NULL_RETURN(seat);
?

use strcmp

I tried to submit
https://phab.enlightenment.org/D5710
https://phab.enlightenment.org/D5711
https://phab.enlightenment.org/D5712
I don't know if I did those correctly or not

OK, I am able to get enlightenment to start on seat1 with this:

OK, it seems that this

I hashed this out as a test, I know if it's the right{F2900829} solution for that or not, ...but with this the failure is

This seems to get Enlightenment to go further
It seems now that it is trying to use a TTY (which would usually make sense on seat0, however seat0 is the only seat that can use TTYs)

Thanks!

I forget now if I mispoke when I said 'gdb'... ...or if I also had a gdb log (which if I did I must have lost)...
IIRC, it was something to do with how /tmp/.X11-unix/X1 was handled... I thought I might have discussed this on an IRC channel with someone to assist me getting that log, but now I can't find it in my scrollbacks...

By removing

It works now!

OK. Something weird happened. I reverted to 3405362b1d3160b2714cf17561a8d48e5405f7e8 and it started working as I said in my previous comment...
but then it seems it must have written something to the configuration, because I tried several commits in that 50 commit range I mentioned (going 25 more commits in the past, then 12 more, then starting at that previous commit, and only going 12 in the past)... ...and then they all worked. Including dc75c4dd7c1085d3fa23d939965639f8130093a0 which didn't work before. I then tried a commit from March 11th two days after I posted this, and after deleting libdir/enlightenment manually to make sure there were no straggling modules left... even THAT worked

Doing a semi-manual form of a poor man's git-bisect, (Start at a commit from about ~March 9th 2015, and attempting a build and run, then jumping 50 commits behind in Enlightenment, I found that the break for 32 bits happened sometime between dc75c4dd7c1085d3fa23d939965639f8130093a0 and 3405362b1d3160b2714cf17561a8d48e5405f7e8 . On that last commit, the about windows appears Those commits are 50 commits apart. I will now try 25 commits behind dc75c4dd7c1085d3fa23d939965639f8130093a0 instead of 50

I hope these are enough logs...

It is. There's definitely something wrong here, but I won't be able to figure out what it is without a test system. I'll try to provision a vm for it sometime, but until then I guess we just won't allow 32bit wayland support.

I hope these are enough logs...
