From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I came from Arch to Void just today and after installing KDE and enabling dbus, I enabled SDDM, I type in my password and it says login failed, I tried lightdm, I couldn't login neither in my user account nor root, I setup plasma to run with xinit, plasma did launch successfully, but sudo NEVER worked inside plasma, it always says "password incorrect, please try again" even though I'm able to sudo inside TTYs

I tried "sudo sddm" and read the logs, it says SDDM: authentication_FAILED for user "" which is weird (it didn't print any names)

There were also some PAM logs in between, I didn't change any PAM configuration

I have elogind installed and enabled too

@notTheCat there's a technique where you boot with a live system, mount your linux system, chroot into it amd change passwords. If you think this is insecure for your system, then you should considering encrypting at least your home diretory/partition.

Do have the startx command installed ? You can use that from the command line without DisplayManager (Switch to a virtual console with e.g. ctrl-alt-F2). And with XFCE4 you can use the command startxfce4 to start from the command line without DisplayManager. This could help troubleshoot.

Do you have an sddm user in the sddm group?

[–] notTheCat@lemmy.ml 1 points 5 months ago (1 children)

Do you have polkit installed?

Also does startplasma-wayland or how its called in the TTY work?

Plasma on X11 is practically unmaintained afaik

[–] notTheCat@lemmy.ml 1 points 5 months ago (1 children)

Yes I have polkit installed

Executing startplasma-wayland returns the following:

startplasmacompositor: Could not start D-Bus, Can you call qdbus?

I don't have an excutable/command named qdbus

I never used Void and think it is meant for people that solve such issues themselves.

I would recommend a distro where even manually installing KDE plasma packages will result in a "just working" Desktop, like Fedora.

Otherwise, contact the Void people.

I did a few minimal installs, currently working on a Qt6-only Wayland-only minimal install to test RAM consumption.
