Xorg.server dies on startup
I'm a Gentoo user who maintains an Artix system for educational purposes. I usually boot up Artix about once a week, and apply the latest updates (pacman -Syu).
Last Saturday the startup of the graphic desktop failed. The boot proceeded normally until SDDM fired up. Then, instead of presenting a login screen, the whole system just froze up.
Today I worked on it a bit. I was able to disable the SDDM service temporarily by commenting out all the contents of /etc/init.d/sddm. So I managed to log in as root and ran pacman-Syu, hoping this would fix the problem. It didn't.
I dug through the log files. Here's some stuff from /var/log/sddm.log:

So then I looked at /var/log/xorg.0.log. This appears to be the real problem.

Please consult the The X.Org Foundation support

for help.

I guess I'll also ask for help at the wiki.x.org web site. Any suggestions will be welcome. Thanks!
