What happened to Wayland?

[AV]

With the recent updates:

control-center-3.22.1-2.fc25
gnome-session-3.22.1-2.fc25
gnome-shell-3.22.1-2.fc25
switcheroo-control-1.0-1.fc25

Wayland seems to have 'disappeared'!

It is no longer mentioned under Settings-Details where I now
see 'Graphics: Intel HD Graphics 5500 (Broadwell GT2)' instead
of 'Wayland...'

If I login choosing 'Gnome' and check I get:

loginctl show-session 2 -p Type
Type=wayland
echo $WAYLAND_DISPLAY 
wayland-0;

If I log in choosing 'Gnome-xorg' and check I get the SAME:

loginctl show-session 2 -p Type
Type=wayland
echo $WAYLAND_DISPLAY 
wayland-0

Something is not kosher. Is this by design or should I start 
reporting bugs.

I see this on a Lenovo T550 with only Intel integrated graphics
and on a Dell Inspiron with hybrid graphics, optimus, nvidea+intel.
(and on this last laptop the new 'tools' do not seem to work as
 intended).

I can't reproduce that in a VM. Please file a bug and send a link.

It would be great if you could participate in tomorrow's test day [1], you can then
debug the issues with dual graphics plumbing developer (Hans de Goede) directly. 
Thanks a lot.

I'm suspicious this second command is incorrect because the session number
is the same. Usually log out then log back in results in different session
number. I bet the old session 2 is still running, and there's a new session
using X.

Without KillUserProcesses=yes, it's pretty much always the case on Fedora
25 that sessions do not quit on logout.

Anyway, type just loginctl to see if there's more than one session for your
user.

That's intentional. The wayland session never bothered to look up the
GL renderer information until now.

The first message got mixed up (I was distracted by breaking
and tearing sounds from bathroom, long due repairs).

The actual machine of interest is an old Dell Inspiron 7720 with
Intel Core I7-3619QM CPU and hybrid graphics, Optimus:
(Intel Ivybridge Mobile + Nvidia Geforce GT 650M).
On it a bare metal install of Fed 25 beta running Wayland.

After above mentioned update Wayland 'seemed to have
disappeared' so I checked with 
'loginctl show-session X -p Type' (hereafter 'loginctl') and
'echo $Wayland_Display' (hereafter 'echo') and found:

Login with Gnome
-loginctl 'Type=x11'
-echo     '-Display'
Login with Gnome on Xorg
-loginctl 'Type=x11'
-echo     '-Display'

As a control I also checked on 2 laptops I actually use,
both with bare metal install of Fed 25 beta + Wayland.

Lenovo Thinkpad T550 with Broadwell Intel HD Graphics 5500, 
Login with Gnome
-loginctl 'Type=wayland'
-echo     'wayland-0'
Login with Gnome on Xorg
-loginctl 'Type=x11'
-echo     '        '

Asus Zenbook with Skylake Intel HD graphics 510
Login with Gnome
-loginctl 'Type=wayland'
-echo     '            '
Login with Gnome on Xorg
-loginctl 'Type=x11'
-echo     '        '

This was as expected (except for the empty string for echo
under Gnome login with the Asus Zenbook)

So the real question was: is the result for the Dell Inspiron
the 'default' behavior for 'hybrids' or has something gone
wrong. Is there a foolproof way of checking if Wayland is 
actually running?
(I have not had the time to dig around with journalctl for
 errors or clues to what is happening)

How about the erratic behavior of 'echo $Wayland_Display'
(empty string with Gnome login on Asus and curious string
'-Display' on both logins with Dell).

If these things are actual bugs what component should I report
them for.

The Settings-Details discrepancy was explained by Adam Jackson.

There is no $Wayland_Display. But there should be $WAYLAND_DISPLAY when under Wayland. See
