Dear community,

I've been having an issue where sometimes when lightdm starts, it will lands on manual login mode (the mode that requires the user to enter both username and password, which appears as "Other"). This happens randomly and I don't know how to reproduce it, but I have captured a log file (/var/log/lightdm.log)

Entering the username or switching to my user isn't that inconvenient but other people that use my computer don't know how to read English nor know that they can switch to the tb user

Thanks.

I commented out the clean up command, hoping that it can solve the problem, but I'm not sure. IT WAS NOT COMMENTED WHEN I CAUGHT THE PROBLEM

Other applications download just fine, but I still can't download the package "org.freedesktop.Platform.GL.default" (which is from org.gnome.Platform) . This has been happening to me yesterday counting from the time I am writing this.

Recently there's a new vuln called "Copy fail" and there are a lot of posts talking about it. I'm just wondering if Void linux team has delivered a oatch yet?

Source: https://www.cve.org/CVERecord?id=CVE-2026-31431

This is not a rude demand for update or anything, I'm trying to raise awareness for the users among the Void linux community.
