Plasma 6 issues about i3-and-kde-plasma HOT 28 OPEN

Hi everyone, I have figured out a solution for this. If we check the journalctl log, we find that no response from KWin is actually the reason behind the shut down not going through. The ksmserver (KDE session manager) requests KWin to close all wayland windows through a DBus method. Since we are not running KWin when using i3, this request does not go through and the shutdown is aborted.

Hence, I have written a fake KWin DBus service (< 30 lines) which, when run, makes sure that the shutdown/logout/restart does not hang up. Here is the code: https://github.com/DMaroo/fakwin. There are build instructions and links to the relevant KDE code in the readme.

Sorry for the intrusion but since this issue could become a general discussion place for Plasma 6 integration, could I ask if you found the need to have some different configuration with respect to the original? Aside from what you've already discussed.

Just this line change, but I'm wondering if it will change again on the next Plasma update. And there may be a better solution than this, I just posted the first thing I got to work.
bindsym $mod+Shift+e exec --no-startup-id qdbus-qt5 org.kde.LogoutPrompt /LogoutPrompt org.kde.LogoutPrompt.promptLogout

from i3-and-kde-plasma.

So changed my line in the i3 config file for using the Plasma logout screen to this:

bindsym $mod+Shift+e exec --no-startup-id qdbus-qt5 org.kde.LogoutPrompt /LogoutPrompt org.kde.LogoutPrompt.promptLogout

Based on this post: https://discuss.kde.org/t/what-command-to-display-the-sddm-shutdown-screen-on-plasma-6/11382
Meta+Shift+E now opens the screen, but still none of the options work.

I noticed this issue aswell when I upgraded a few hours ago. It seems that when you call the logout process on KDE 6 it attempts to invoke KWin for the different processes such as shutdown and logoff, but this is a problem considering we are replacing KWin with i3, so KWin can't be active at the same time as i3. I honestly have no idea if there is an alternative way to bypass KWin to logout anymore considering that plasma 5 used the ksmserver to invoke logging out previously and that worked fine, but now that's changed.

from i3-and-kde-plasma.

Okay, so I'm a moron and I did some more digging and realized it's not KWin's fault, and it is actually the polkit authenticator agent, which is disconnected for some reason. Ignore the scuffed screenshot for the second image it's scrot acting strange, but the culprit appears to be polkit and it's authenticator agent not connecting properly when kde launches with i3.

The prompt is showing up but I guess the real issue is with the KWin / polkit authenticator agent which showed @ChodyFlims . Hope to get solutions and support for that.

Facing the same, I'd also like to add the task bar has has lost all cosmetics. It's still fully functional, but more like a black bar across the screen.

Looks amazing! Did you consider though changing the ksmserver instead, so when the request reports an error it is ignored and the service proceeds with shutting down?

from i3-and-kde-plasma.

Changing ksmserver would require patching the /usr/bin/plasma-shutdown binary, which would not be a particularly stable/reliable/robust way to go about it. I feel that having a fake service makes it easy to change the behavior of KDE in the least intrusive way.

On Archlinux I did, but it looks like some Arch packaging bug rather than something to do with KDE6. The file /usr/share/xsessions/plasma-i3.desktop disappeared and I had to re-create it.

Could you please explain how you got i3 to work with plasma?
For Option 1 I changed systemctl mask plasma-kwin_x11.service --user to systemctl mask plasma-kwin_wayland.service --user but I just get a blank black screen with no cursor when logging in.

Tried Option 2, changed Exec=env KDEWM=/usr/bin/i3 /usr/bin/startplasma-x11 to Exec=env KDEWM=/usr/bin/i3 /usr/bin/startplasma-wayland, still no luck however.

Why did you change it? I didn't touch kwin_wayland at all, I only had to mask kwin_x11.service.

Did you create'n'enable plasma-i3 user service?

(worth noting though, I've used i3 + KDE before they migrated to systemd user services, so I have had an XSession file that starts i3, which I've been using till now. However, now that you commented I tested running the usual "KDE X11" session and it starts i3 + KDE for me as well, so you don't have to create an XSession file).

Tried Option 2

Option 2 I didn't test as I don't want to disable systemd support in KDE.

Why did you change it? I didn't touch kwin_wayland at all, I only had to mask kwin_x11.service.

Are you still logging in with X11?
I'm using SDDM, and I have an option to sign in with either X11 or Wayland after the update.
If I didn't change the name, it would only apply with signing in with X11.

Yes, I have all the files (along with correct permissions and settings I'm assuming) as I was using i3 + KDE before the update just fine.

Funny thing is after I went back and followed the instructions again, it always starts with kwin no matter what I try to disable or mask.

Yes, I log in with X11. i3 is an X11 thing, it's not applicable to Wayland.

If you want KDE with tiling in Wayland, you might have to try built-in tiling in kwin that they added an year ago and should be part of KDE6. Checking it out has been on my todo list for a long time but I still haven't gotten to it. You might try it if you feel motivated 😊

Funny thing is after I went back and followed the instructions again, it always starts with kwin no matter what I try to disable or mask.

Just to be clear: among other things that you tried, did you try masking out kwin_x11, enabling plasma-i3, and then logging into KDE X11 session?

Just to be clear: among other things that you tried, did you try masking out kwin_x11, enabling plasma-i3, and then logging into KDE X11 session?

Yep:

systemctl status plasma-kwin_x11.service --user
○ plasma-kwin_x11.service
     Loaded: masked (Reason: Unit plasma-kwin_x11.service is masked.)
     Active: inactive (dead)

systemctl status plasma-kwin_wayland.service --user
○ plasma-kwin_wayland.service
     Loaded: masked (Reason: Unit plasma-kwin_wayland.service is masked.)
     Active: inactive (dead)

systemctl status plasma-i3.service --user
○ plasma-i3.service - Launch Plasma with i3
     Loaded: loaded (/home/XXX/.config/systemd/user/plasma-i3.service; enabled; preset: enabled)
     Active: inactive (dead)

It's still loading kwin somehow thereby not allowing i3 to take over.

Side note :- I've tried out the in-built tiling, It's defiantly not bad, and a great place for a beginner to get a taste of tiling windows. Unfortunately it's nowhere near the experience provided by the true tiling manager

Interesting. Can you perhaps with all above being masked log into KDE x11 session, post systemctl --user status and a systemctl --user status plasma-i3?

I'm sure as the userbase of the in-built tiling increases, so will the quality of the implementation.

@varad-kadam can you perhaps look at systemsettings → Session → Desktop Session and make Session Restore option to have Start with empty session value and see if that helps.

from i3-and-kde-plasma.

Start with empty session

That's what it's always been set to, made sure to re-set and check... but same thing

from i3-and-kde-plasma.

@varad-kadam Okay, so, one suspicious thing is that I can not see kwin word in your systemctl --user status at all. I think you might have disabled systemd in KDE while trying out Option 2. Please enable it back and see if that changes anything.

Another thing I just noticed on my laptop: I was trying a Wayland session just to see if I have kwin infix in the systemctl user output there, and afterwards I was getting all sort of issues on X11 session: black screen, infinite load… I was trying to log out, to restart sddm, to kill kwin, to stop user session… To no avail: the only thing that helped is full reboot.

I'm saying that because I saw you mentioned black screen before and that you were tinkering with Wayland session. Well, just so you know: you'll have to do a full reboot if you're experimenting and for whatever reason logged into a Wayland session. Otherwise it's just not gonna work properly.

from i3-and-kde-plasma.

@Hi-Angel for the longest time I couldn't figure out what you meant by disabling systemd, was thinking if it had been disabled I would be seeing a lot more problems.

Good news, yes, enabling allowed x11 / wayland service to actually be stopped and i3 to take over.
I can't login to wayland if plasma-kwin_wayland.service is masked, just end up on the SDDM screen even after repeated attempts, however X11 works just fine.
Thank you very much for helping debug this.

It does circle around to my initial observation; my taskbar / bottom panel being completely blank, and all taskbar widgets (battery, notifications, internet settings volume, etc.) also lacking any theming, just a solid black background.

Since no one else has mentioned it, is this an issue on your end as well caused by the update, or something else?
I thought i3 couldn't hand the floating and translucent effects, so I've tried disabling those, but that doesn't seem to change anything.

Yeah, sorry about that, I was talking about KDE using systemd-based startup, which might be disabled with systemdBoot false.

No problem. Just to clarify: you don't have to mask kwin_wayland. i3 is an X11-only thing, and you can additionally have KDE Wayland if you want to try some stuff there. It works for me, as you can see by my prev. comment I have both.

That I don't know by what could be caused. For me everything seems to work fine, here's a screenshot just as I'm typing the message

KDE version: 6.0.2, Distro: Archlinux

Ahh, I see, hopefully it's just something minor, I'll play around with it a bit see if anything changes, thanks again!

Just leaving it here in case anyone runs into the same, transparency effects don't work very well on plasma 6 with i3. This usually results in black panels, menus, and whatever else is trying to use the same.

Changing themes or to solid colors works much better.

Transparency works fine for me on KDE6 + i3 + Picom. What compositor are you using for transparency effect?

from i3-and-kde-plasma.

I take that back, @ds196 issue #55 fixes it for me, picom-git used to fail / not implement proper blurring in all scenarios.
