Re: System booting to black screen and not sddm after update

What was part of the update? It crashes but seems to at least start xorg so you should have a xorg log from /var/log/Xorg.0.log you can share, as well as https://wiki.archlinux.org/title/Core_d … _core_dump which should give us info on the crash.

On a random guess, do you have xf86-video-amdgpu installed and does it help to remove it?

Re: System booting to black screen and not sddm after update

What was part of the update?

util-linux-libs 2.40.4-1 -> 2.41-2 | cifs-utils 7.2-1 -> 7.3-1 | shadow 4.17.3-1 -> 4.17.4-1 | util-linux 2.40.4-1 -> 2.41-2 | fakeroot 1.37-1 -> 1.37.1-1 | fastfetch 2.39.0-1 -> 2.39.1-1 | iptables 1:1.8.10-2 -> 1:18.11-1 | libusb 1.0.27-1 -> 1.0.28-1 | pkgconf 2.3.0-1 -> 2.4.3-1

After the issue happened and I was able to get into KDE, I figured might have been an update issue causing problems so I downgraded all the packages from that date using the Arch Linux Archive. All packages downgrade to previous except for util-linux-libs, util-linux, fakeroot and iptables. Not sure if this was the right approach to the situation but it seemed like the correct one since the issue happened after the update.

as well as https://wiki.archlinux.org/title/Core_d … _core_dump which should give us info on the crash.

I tried following the wiki to get this information but was having trouble (lack of knowledge to do correctly)

xf86-video-amdgpu 23.0.0.-2 is installed

While waiting for a reply here, I found a post on the KDE forums and it solved the problem I had but I'm still curious if there is more to the issue and if there is anything I can do to correct it?

I don't have 2 monitors, I just changed the sddm theme while in kde, rebooted and now sddm is working again.
