[SOLVED] SDDM Theme Archlinux-simplyblack

quyro · 2024-09-09 17:20:18

Hello everyone,

after the installation I started to get everything working and thus also a login screen with sddm.
The thing is, after I installed a theme package (https://github.com/Guidobelix/archlinux-themes-sddm) and set up the archlinux-simpyblack theme, I get a black screen and can't type anything anymore.

I installed the theme from the AUR (it's also used as an example in the wiki), but I made the stupid mistake of not building it and just rebooting.

Is there any way to restore my laptop or do I have to reinstall everything?

Thank you all in advance

Are you not able to get to TTY?

https://bbs.archlinux.org/viewtopic.php?id=299183 - see last post for how to manually revert the theme
https://github.com/Guidobelix/archlinux-themes-sddm is likely gonna depend on qt5-graphicaleffects, qt5-quickcontrols2, qt5-svg and maybe more Qt5 packages

Try installing "qt5-declarative" first and see if that does the trick. I had the same issue and that was all that was missing for me, but I could have already had another dependency installed. Though that is what sddm states is required for using qt5 themes.

As for getting back to your system when you're on the black screen, press ctrl + alt + f3 (or another f key) to switch to another tty, sddm will be running on either 1 or 2 usually.
From the command line you can reset your sddm config to use the default theme, or just install the aforementioned package and then restart and see if it fixes it.

You don't need to reinstall everything its an easy fix, switch TTY, sort it out, reboot.

My system is fixed, thank you (I thought TTY was locked to F4), but the black screen problem remains whenever I select a theme. It only works if I leave the value of Current=... empty (the package is now installed to, qt5-declarative & 6.

Could it be that I'm using the wrong theme, as I've tried all 3 installed themes from SDDM?

Idk what the archlinux-themes-sddm themes depend on but "breeze" should work w/o any Qt5 package and for archlinux-themes-sddm the suggestion would be to go with the dependencies of https://aur.archlinux.org/packages/sddm-sugar-candy-git and try to install those Qt5 packages.

As you said, "breeze" works, but it is also the default theme. After I installed these dependencies, it still didn't work.

I use the archlinux-soft-grey theme from that same package.

I had the same problem but I only had to install that declarative package to get it working.

This is the results of "pacman -Qs qt5"

qt5-base
qt5-declarative
qt5-svg
qt5-tools
qt5-translations
qt5-x11extras

It may be that there's another dependency that its expecting, but these are all the qt5 ones I have installed in case any of them help.

@quyro do you have a system journal covering an attempt to use a disfunctional theme?
(QML errors should show up there, if there's a coredump, see https://wiki.archlinux.org/title/Core_d … _core_dump )

I checked the journal and found out that there are two versions of some Qt libraries. I just ran "pacman -Syu" and all my problems were solved (next time I will check the journal first)

Thanks for the help
