Issues with SDDM and Hyprland

thedrone7 · 2023-06-02 01:52:53

I just installed sddm-git on my arch machine running hyprland. Although everywhere I go it is as simple as installing and enabling, I seem to have a lot of errors.

I just ran the following command on my fresh install so this is all just the defaults.

sddm-greeter --test-mode

1. Malformed entry

Malformed entry in "/usr/share/wayland-sessions/hyprland.desktop"

I have verified this .desktop file many times, even used some utilities such as desktop-file-validate and there are absolutely no issues with this file.

2. Socket error

Socket error:  "QLocalSocket::connectToServer: Invalid name"

None of the solutions I could find online helped me with this one.

3. Missing files

file:///usr/lib/qt/qml/SddmComponents/LayoutBox.qml:44:9: QML Image: Cannot open: file:///usr/share/sddm/flags/af.png

There are a lot of these. I tried installing all qt packages, and all of them are the same version

5.15.9-1

.

(On running without test-mode)
4. Missing platform

[21:35:37.450] (II) GREETER: Could not load the Qt platform plugin "xcb" in "" even though it was found.
[21:35:37.450] (EE) GREETER: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

According to my searches, to fix this, I must install some specific packages so the libs exist, but the packages were already installed. I even tried re-installing with no luck.

However, a bit more looking around I found out, that the lib is in qt6 plugins folder, and not in qt5 plugins folder. My installed apps have both qt5 and qt6 as dependencies so I cannot get rid of either of them to see if that helps.

Any help would be greatly appreciated

Have you tried simply enabling it instead of testing it? Most of this reads like some issues in your environment and I'm not sure how well tested the greeter test is when ran in a wayland/xwayland session for that matter.

I did, it just left me with a blank screen when I tried enabling it on boot. I switched to TTY2 and logged in from the shell to disable it but no luck that way either.

try autologin for SDDM, check this video.

Did try that too, it simply does not launch. That is the weirdest part, everywhere I've seen it works out of the box and I am completely clueless what I may have done wrong.

The xcb error you get sounds like you built it against the wrong qt release. or you're using some broken qt theme. What do you get from

lddtree /usr/bin/sddm{,-greeter} #pax-utils
pacman -Qg qt6 qt5

Upstream recently started a qt6 port, if you accidentally build against that and it isn't yet entirely stable that could explain things, do you still have access to/can you do a rebuild and post the log from that?

I think you did catch the issue but this is not something I am familiar with.

That all looks normal, did you do any non-standard configuration? When getting the white screen is a xorg log generated and what are it's contents? Would be under /var/log/Xorg.0.log Do you override QT_QPA_PLATFORM somewhere?

printenv | grep QT_QPA
