Hello

Thunderbird supports wayland from long now.

This can be enabled by environment variable: MOZ_ENABLE_WAYLAND=1

Can someone clarify if Wayland code is stable enough?

Or it can still cause thunderbird to crash in some cases?

Please clarify

Thank you

Amish

Any one has answer? Any thunderbird developers here?

I'd be happy to try it out if you tell me where to put the variable in
my Ubuntu system.

No, just users

Fedora 40

If I start thunderbird normally from the Gnome menu, then look in
Help/Troubleshooting Info

Under Window Protocol I see "xwayland" (which I think is the
compatibility layer)

If I open a terminal, then "export MOZ_ENABLE_WAYLAND=1"
and start thunderbird from the terminal

the Window Protocol shows as "x11"

for a very brief test, both ways work, but I don't think either method
is using native Wayland?

Ubuntu 22.04, the Windows Protocol shows "Wayland" without having
exported the variable. No crashes, Thunderbird has been working
perfectly well for more than half a year.

You can put it in your ~/.profile OR ~/.bash_profile or ~/.zsh_profile
(based on what shell you use).

OR test by running thunderbird as:
MOZ_ENABLE_WAYLAND=1 thunderbird

You must be using wayland fot this to work.

Use xorg xeyes program to check visually if application is using X11 or
Wayland. If eyes move when you move mouse over the app then its using
X11 and if eyes don't move then its using Wayland.

For me it shows Window protocol as wayland. (not xwayland)

Which means native Wayland.

xwayland possibly means X11 via Wayland
x11 means direct X11 no wayland.

There is an answer on askubuntu:
https://askubuntu.com/questions/1456684/how-to-initialize-firefox-on-wayland-always-by-default

It's about Firefox but MOZ_ENABLE_WAYLAND=1 enables wayland for
Thunderbird as well.

It can be possible that Ubuntu has set MOZ_ENABLE_WAYLAND=1 variable by
default. Otherwise thunderbird by default uses X11.

As far as I know, Wayland is not officially supported, see the system requirements:
https://www.thunderbird.net/en-US/thunderbird/115.8.1/system-requirements/

There are also a few things that don't work under Wayland:
https://bugzilla.mozilla.org/show_bug.cgi?id=635134

That affects the "minimise to tray" function in Betterbird which doesn't work on
Wayland.

Firefox on the same Fedora machine shows Windows Protocol "wayland" so
it seems thunderbird is only build for x11 (and can run on native "x11"
or "xwayland")

Ubuntu has login options of X11 or Wayland that you
can set up, and that's how I tested the Firefox capability,
when the Mozilla graphics person was complaining about
what a nuisance Linux support had become (with three options).
And at the time, by switching between X11 and Wayland
at login, and using the environment variable, I was
able to test Firefox in all three modes.

There is no particular reason for Thunderbird to be
different, as it's picking up XUL.dll or XUL.so (huge files)
and these are the embodiment of the capability. The
Thunderbird build environment also has an option to
"build browser", so you can make the source tree
produce a browser instead. This is part of the
reason I feel any demonstrated Firefox capability
(for a certain ESR used to build Thunderbird),
the same capabilities should percolate through.
If the Firefox ESR is new enough, all three modes
should be there.

(From September 2022)

"wayland" [ means working directly under wayland at present ]
"xwayland" [ running legacy X11 by using xwayland compatibility part of wayland]
"x11" [ running X11 under X11 ]

When testing, I hope your Fedora is dual-mode too, so
you can run the three test cases. First, verify you
can demo all three modes on Firefox, then... cast
shade on Thunderbird :-)
