Thanks for clarifying; indeed it's the XWayland process that crashes.

I actually support leaving X11 behind---I use wayland myself and I agree 
it's the correct evolutionary path for system graphics.


I piped up in this discussion to point out that Wayland has rough 
spots.  There are many legacy X11 apps still around, some possibly 
buggy. They should not crash XWayland in a way that nukes the entire 
desktop.


Another problem is the reliability of input streams. The mouse behavior 
is realy weird sometimes, as if it was simultaneously losing events and 
getting spurious ones.


I suspect that these issues are marginal enough to not affect the 
majority of users, which is why they aren't seen as urgent, but I think 
they should be addressed for a mainstream Wayland use. I would like to 
help debugging that, but it's a complex system and I wasn't able to find 
reliable information on how to look inside those issues. For instance, I 
understand the separation of layers in X11, and I know how to debug X11 
events using xev and such---but I have no idea how to look into why my 
mouse clicks in Firefox under Wayland are so weird and unpredictable.

So I am confused---I thought it is a problem in Wayland, perhaps in its

Wayland should be resistant to this 'fuzzing'.

Re, this being the GNOME bug, I think any app with this behavior will

understand the GTK app enough to write a minimal replication.


Perhaps you are implying that when Wayland is the only choice, X11 
applications will be replaced by wayland apps and the X11 emulation will 
be removed form Wayland, so this will no longer be an issue?


I thought I checked that the 'true' X11 server does not crash in this 
scenario,  but I realize now that I am not sure.


BTW, I did report this in Gnome as well

Please don't. That is an X11-specific bug; you can see the top 10 
frames of the backtrace are all X11 code. I will reassign it to mutter, 
but if you want it to actually get fixed, you should really report it 
upstream, because the chances of it attracting attention on Red Hat 
Bugzilla are slim. I recommend you only report GNOME bugs downstream if 
you've found a downstream packaging issue or if you need the downstream

I have an open bz about reliable wayland crashes:

https://bugzilla.redhat.com/show_bug.cgi?id=1539992

Besides being very inconvenient because of course they take the entire 
session with it, such crashes can usually be leveraged to achieve code 
execution, and if the behavior can be triggered by remote data, RCEs. 
Therefore, I would argue it is a serious issue.


Basically, the crash is triggered by excessive resource usage that can 
be seen via xrestop. Unfortunately I was unable to debug the issue: the 
GTK+  forest overwhelmed my capabilities ('callbacks, callbacks, 
everywhere').


This is an old bug currently assigned to gnome-session. Should I 
reassign it to Wayland?

Keeping in mind that testing anything now (before plasma 5.21 is 
preliminary), but... best way to test:

1.  create a new user for testing purposes
2.  make sure plasma-workspace-wayland pkg is installed
3.  login using Desktop Session: Plasma (wayland)

Re: F34 Change proposal: Wayland by Default for KDE Plasma Desktop (System-Wide Change)

[Gerald B. Cox]

I really don't see we have much of a choice here.  X11 is eventually going away 
and Wayland is the path forward.  That's already been decided, so at this point 
it isn't a matter for debate.  Human nature being what it is, people tend to 
procrastinate and not do anything until pressed up against a deadline - so here 
we are.  Wayland has been discussed for over a decade now, so this shouldn't be 
a surprise to anyone.  I've been opening bugs whenever I see issues, so 
upstream, packagers and end users are aware of the issue.  If I know of a 
workaround or alternative that works, I list it.  There is currently an open 
issue with a black screen and SDDM in conjunction with Radeon graphics.  In my 
opinion, if this isn't resolved, we should switch to GDM rather than delay 
making Wayland the default.  If a particular application doesn't work in 
Wayland, we should advise people of alternatives rather than holding this 
change hostage.  I've seen great improvements between 5.19 and 5.20 - and 5.2
 1 promises more.  So if you haven't tried wayland and plasma lately - you 
should try again.

If you notice issues, please open bugs.

It looks like most of the issues listed [1] still have open bug reports. Are 
these bug reports just not getting closed or are these problems not getting

This can't be fully appreciated until plasma-5.21 lands.  No formal 
decisions will be made until at least then.

And until then, if there are any issues you want to be considered blocking, 
please file bugs.  Currently I see nothing blocking the tracker

That's related, but different.  However, applications will have to adapt 
sooner or later, may as well be sooner.

Can we revert this decision, seems almost all the people have the same
opinion ... that Plasma on Wayland is not ready for production.
IMHO, try run it in wayland should be a optin . 

We have been aware of the wayland induced issues for a couple of years.
The fedora kde/qt team are aware of the issues wayland causes and just
blame the apps.

I'm personally running Plasma Wayland on a couple of computers now on
Plasma 5.18 on Fedora 32. To do so, all you need to do is install
"plasma-workspace-wayland" and select the "Plasma (Wayland) (Wayland)
(Wayland)" session (yes really, the text is fixed with Plasma 5.19)
from the SDDM drop down.

You'll be missing all the remaining "basic" features implemented into
kwin-wayland like middle click paste and screencasting support, but
those will become available with Plasma 5.20. KDE upstream has a
specific "goal" to get Wayland support to first-class status:
https://community.kde.org/Goals/Wayland

My desire is to activate it as default in Rawhide as soon as possible
and start working with KDE upstream to hammer things out throughout
the entire development cycle for Fedora 34. We will probably wind up
shipping Plasma 5.21 or Plasma 5.22 for Fedora 34 GA, and getting
testing and such going as early as possible will help get the actual
target release for Fedora 34 in good shape for Plasma Wayland.

But of course, if by the time we get to beta freeze and it's too
buggy, we'll flip the default back to Xorg while shipping both as
options on the media and try again for Fedora 35.

I was trying it on F32. I was ready to see various annoyances, since
the proposal says that a lot of issues will be only fixed in F34, but
I hoped that in F32 the desktop will at least look normal when I log
in :)

Probably not much :) I was just curious to see how good/bad the
situation is currently on F32. From the optimistic wording in the
change request I imagined that most things already work and the latest
releases only fix some final annoyances... but maybe this is more true
about F33 than F32, or I just have some weirdness in my existing
configuration...

Ondrej, what Fedora version are you on?  The change claims:

  With KDE Plasma 5.20, the KDE Plasma desktop environment has reached a
  point where nearly all commonly used features in the desktop and all
  major applications function in the Plasma Wayland environment on all
  major GPUs (including NVIDIA with the proprietary driver).

I'd consider a move to F34 just to test early, but even F34 still seems to
have 5.19.90.

The change says:

  How To Test
  ===
  Log into a KDE Plasma desktop. Do any activity you would normally do in
  your daily desktop use: launching applications, configuring displays,
  etc. Things should work the same way under Wayland as they used to
  under X.

Even a simple link to step-by-step howto would help.  How much sense does
it have to test F32/F33?

I do not think that Plasma on Wayland is ready for production use at this 
time. E.g., middle-click paste support is still incomplete: interoperability 
of the feature with X11 and GTK applications is not working yet. (X11 
because the XWayland parts of the middle-click feature are not yet 
implemented in KWin-Wayland, GTK because KWin supports only the final 
standardized version of the extension whereas GTK apparently still only 
implements its own pre-standard version with a differently-named namespace.) 
I believe that there are also other open issues with Plasma on Wayland.

It seems all the necessary packages were pulled in as dependencies via
plasma-workspace-wayland.

$ sudo dnf info --installed *wayland* | grep Name
Name : kf5-kwayland
Name : kwayland-integration
Name : kwin-wayland
Name : libwayland-client
Name : libwayland-client
Name : libwayland-cursor
Name : libwayland-cursor

Name : libwayland-server
Name : plasma-workspace-wayland
Name : qt5-qtwayland
Name : qt5-qtwayland-devel
Name : xorg-x11-server-Xwayland

Looking at the available but not installed packages that match
*wayland* I don't see any that would be relevant.

Oh, thanks for the info! So I guess the only Wayland issue for me so
far is the messed up resolution/screen settings. Once I get past that
I'll probably see the "normal" known issues, too :)

That's definitely possible... However this is a single-user machine
and I don't really feel like creating a new user :)

If I find some time I'll try it on my other laptop and/or dig deeper...

Re: F34 Change proposal: Wayland by Default for KDE Plasma Desktop (System-Wide Change)

[Silvia Sánchez]

Ondrej,

You need to install Kwin Wayland and another package that will provide the
backend.
My experience wasn't the best, several apps crashed, effects stuttered or
were very slow, even typing felt slower.  But at least my desktop looked
normal.
One comment:  the logging out issue is not because of Wayland.  I have the
same with Xorg, and there are several bug reports pointing to the same
issue.

Kind regards,
Lailah

So yesterday I tried to log in to the KDE Plasma + Wayland session on
my laptop (F32) and the experience was unfortunately quite horrible...

1. When I logged out of the X session, switched to Wayland on the
login screen, and logged in, I only got a black screen. After I
rebooted, I managed to login to the Wayland session (I have automatic
login after boot enabled), but...
2. The desktop was all squeezed into a small 1024x786 rectangle in the
upper left corner of the screen (my screen is 1920x1080). So I opened
system settings to change the resolution, but...
3. The screen settings were showing "manufacturer_TODO" and
"model_TODO" as the name of the screen and the only resolution offered
was 1024x786.
4. The window layout of my KDE session was not preserved (I think even
the distribution of windows to activities was lost). But I probably
shouldn't expect this to work...
5. Logging out of the Wayland session gave me just a black screen with
blinking cursor, no login screen.

Reading the other posts in this thread it seems I'm the only one
experiencing such serious breakage (maybe except 4., which is
understandable), so I'm wondering if I did something wrong... I simply
installed plasma-workspace-wayland, logged out, and then logged in
selecting "Plasma (Wayland) (Wayland)" from the session dropdown.

KDE Plasma from F32 on Wayland has a major issue with broken keyboard
layout indicator. This issue need to be fixed first before making it
default.

Right, but have there been any investigations to see if those release criteria 
are fulfilled on Plasma + Wayland? If it doesn't currently meet all criteria, 
what are the known blockers?

I tested firefox also, using google meet.  On firefox, no windows are
available to choose for sharing when run under wayland.  All the windows
show as expected
running firefox on plasma/X11.  That's a bit different than chrome but
seems to be some bug common between them.

I haven't tested but you can probaly only share other Xwayland windows
(chrome still runs on Xwayland last I checked)

The wayland-native way of sharing app windows is xdg-desktop-portal
which has a kde implementation:
https://invent.kde.org/plasma/xdg-desktop-portal-kde
https://koji.fedoraproject.org/koji/packageinfo?packageID=24326

Do you have xdg-desktop-portal-kde installed?

> Where can I report this issue?

Now that also needs to be supported by whatever videoconferencing
software you use (in this case chrome); you might want to try firefox
just to see if it's better...

So to sum it up:
 - if this works on FF but not chrome, it's a chrome bug
 - if this works on e.g. gnome with either browsers but not plasma, it's
a kde bug


Good luck (?)

I have tested kde/wayland on F32 but have hit a roadblock.  We are all
working from home and need to share screens.  Using google chrome, on X11
when I
try to share an app window (which is my usual choice) there are no
problems, but on wayland only some of the windows are given as choices to
share.  I haven't
found any particular pattern to which windows are listed (is it just from
certain desktops?)  I believe this isn't chrome specific (have to retest).

Where can I report this issue?

The main issue I have with wayland on kde is the support for the second 
screen. In the previous laptop it did not detect the second screen while with 
laptop the second screen is detected and show but I can not see its content.

FWIW in both cases gnome on wayland had not these issues.

If this issues are fixed I will gladly change, there are several features that 
I like there like the support for per screen scale multiplier.

== Detailed Description ==

With KDE Plasma 5.20, the KDE Plasma desktop environment has reached 
a

point where nearly all commonly used features in the desktop and all
major applications function in the Plasma Wayland environment on all
major GPUs (including NVIDIA with the proprietary driver). Starting
with Plasma 5.20 in Fedora 34, we will change the default
configuration for Wayland and X11 Plasma sessions so that Wayland is
preferred and used by default, while permitting the X11 session to be
selected as the alternative desktop environment option.

== Feedback ==

 Is Wayland ready? 
Wayland has been used by default for Fedora Workstation (which uses
GNOME) since Fedora 25. And while it was somewhat immature initially,
today it is a very rock-solid experience on virtually everything
Fedora Workstation runs on. The change in Fedora 25 kickstarted the
drive to get everything working on Wayland, and the Workstation team
succeeded beyond their wildest dreams. Firefox has been 
Wayland-native

by default since Fedora 31 as well.

On the KDE side, serious work into supporting Wayland started shortly
after GNOME switched to Wayland by default. Unlike GNOME, KDE has a
much broader stack in its toolkit, and it has taken longer to get to 
a

usable state. With the Plasma 5.20 release, the Wayland protocol for
screencasting as well as middle-click paste finally are supported,
completing the required feature set for switching to Wayland by
default.

 What about NVIDIA? 
Plasma, in fact, ''does'' support NVIDIA GPUs with the proprietary
driver on Wayland. It needs to be manually activated, which will be
taken care of by the kwin-wayland-nvidia package. So the
expectation is that all major GPUs will work just fine.

 Why not keep using X11? 
The fact of the matter is, Xorg is in
[
"hard maintenance mode"] per [[User:Uraeus|Christian Schaller]] and
development on it has basically stopped beyond the most critical of
fixes. Combined with the rapid maturation of the Wayland session in
KDE Plasma, this is the best time to make the switch and push things
over the edge for the KDE ecosystem in the same way that Fedora
Workstation did for the GNOME ecosystem.

== Benefit to Fedora ==
Fedora has long been a leader in advancing the adoption of the 
Wayland

protocol as part of the overall strategy to improve the Linux
graphical software stack. Much of the quality of Wayland for GNOME 
can
be attributed to the work done by the Fedora Workstation WG as part 
of

advancing the GNOME platform. It is now the KDE SIG's turn to do the
same for the KDE platform. By making this change, we are helping push
the adoption forward for newer, more streamlined, and overall more
actively developed graphics technology for the KDE ecosystem.

== Scope ==
* Proposal owners:
** Modify {{package|kwin}} to switch to Wayland
*** Split out /usr/bin/kwin_x11 to the
kwin-x11 subpackage.
*** Make {{package|kwin}} require kwin-wayland and
recommend kwin-x11
*** Add kwin-wayland-nvidia subpackage which contains
/usr/lib/environment.d/10-kwin-wayland-nvidia.conf to 
set
$KWIN_DRM_USE_EGL_STREAMS to 1. This 
package

will have have a Supplements dependency (kwin-wayland and
kmod-nvidia).
** Modify {{package|plasma-workspace}} to switch to Wayland
*** Rename /usr/share/xsessions/plasma.desktop to
/usr/share/xsessions/plasma-xorg.desktop, subpackage it
out as plasma-workspace-xorg, and have it require

to /usr/share/wayland-sessions/plasma.desktop
*** Make {{package|plasma-workspace}} require
plasma-workspace-wayland and recommend
plasma-workspace-xorg
** Modify @kde-desktop comps group for Fedora 34 to
include plasma-workspace-xorg for the media.

It probably will not. Everything related to this is different, and there's
nothing as easy or as nice. You will probably want to select the X session
rather than the proposed new default.

Does it now have support for custom keymappings?  That is, does it have
a way to set a user keymap as the default? X has a very mature system
for setting this, so I can have my custom keymapping everywhere except
in editing the grub menu.  I've thought about buying a programmable
ergonomic keyboard so this would no longer be an issue, but my current
setup works.  Will it now work in Wayland?

Does it allow booting from multiuser?  Is there something equivalent to
startx so I can start it on the virtual console of my choice?

Or are these obsolete concepts in Wayland?

A lot of work has gone into solidifying the experience upstream, and
I'm currently running Plasma 5.18.5 on F32 (on Intel GPU system) and
Plasma 5.19.5 on F33 (on NVIDIA GPU system) and things are working
pretty well so far. The plan is to do the switch in Rawhide early and
work with KDE upstream to knock out the remaining issues to offer a
solid experience with the Plasma release we ship with Fedora 34 GA.
Based on the timelines, we're probably looking at 5.22 for F34 GA, but
I want to make the switch as part of importing the 5.20 beta next week
and give feedback ASAP.

The problem with the current situation is that if we *don't* do this,
there's no pressure to push things forward upstream and get everything
*working*. Doing this will force focus and priority to get everything
working. This strategy was employed to get GNOME Wayland in good shape
and we're in a better place now than GNOME was when the switch was
made in Fedora 25.

Yes, I don't see KDE Wayland sufficiently mature to actually work as a
default.  It needs more work and testing.

Hi Ben,

On 9/8/2020 8:28 AM, Ben Cotton wrote:

Change the default session selection in SDDM to prefer the
Wayland-based KDE Plasma Desktop session over the X11-based one.

* Responsible WG: KDE SIG


== Detailed Description ==

With KDE Plasma 5.20, the KDE Plasma desktop environment has reached a
point where nearly all commonly used features in the desktop and all
major applications function in the Plasma Wayland environment on all
major GPUs (including NVIDIA with the proprietary driver). Starting
with Plasma 5.20 in Fedora 34, we will change the default
configuration for Wayland and X11 Plasma sessions so that Wayland is
preferred and used by default, while permitting the X11 session to be
selected as the alternative desktop environment option.

== Feedback ==

 Is Wayland ready? 
Wayland has been used by default for Fedora Workstation (which uses
GNOME) since Fedora 25. And while it was somewhat immature initially,
today it is a very rock-solid experience on virtually everything
Fedora Workstation runs on. The change in Fedora 25 kickstarted the
drive to get everything working on Wayland, and the Workstation team
succeeded beyond their wildest dreams. Firefox has been Wayland-native
by default since Fedora 31 as well.

On the KDE side, serious work into supporting Wayland started shortly
after GNOME switched to Wayland by default. Unlike GNOME, KDE has a
much broader stack in its toolkit, and it has taken longer to get to a
usable state. With the Plasma 5.20 release, the Wayland protocol for
screencasting as well as middle-click paste finally are supported,
completing the required feature set for switching to Wayland by
default.

 What about NVIDIA? 
Plasma, in fact, ''does'' support NVIDIA GPUs with the proprietary
driver on Wayland. It needs to be manually activated, which will be
taken care of by the kwin-wayland-nvidia package. So the
expectation is that all major GPUs will work just fine.

 Why not keep using X11? 
The fact of the matter is, Xorg is in
[https://blogs.gnome.org/uraeus/2019/06/24/on-the-road-to-fedora-workstation-31/
"hard maintenance mode"] per [[User:Uraeus|Christian Schaller]] and
development on it has basically stopped beyond the most critical of
fixes. Combined with the rapid maturation of the Wayland session in
KDE Plasma, this is the best time to make the switch and push things
over the edge for the KDE ecosystem in the same way that Fedora
Workstation did for the GNOME ecosystem.

== Benefit to Fedora ==
Fedora has long been a leader in advancing the adoption of the Wayland
protocol as part of the overall strategy to improve the Linux
graphical software stack. Much of the quality of Wayland for GNOME can
be attributed to the work done by the Fedora Workstation WG as part of
advancing the GNOME platform. It is now the KDE SIG's turn to do the
same for the KDE platform. By making this change, we are helping push
the adoption forward for newer, more streamlined, and overall more

== Upgrade/compatibility impact ==
Systems using certain (very old) graphics hardware or graphics drivers
(matrox, etc.) may have problems running the Wayland session. In these
(rare) cases, users may have to configure SDDM to use X11.

== How To Test ==
Log into a KDE Plasma desktop. Do any activity you would normally do
in your daily desktop use: launching applications, configuring
