Note in the log the string onnected does not appear. AFAICT, only the use of xf86-video-intel DDX
driver, which last had an official release in 2015, causes that omission.

Easier solution is to purge xf86-video-intel, which when server version is 1.17.0 or higher, should
automagically cause utilization of the newer modesetting DDX driver on X restart or reboot. Other
option is to reconfigure /etc/X11/xorg.conf.d/50-device.conf to specify driver modesetting. The DDX
modesetting driver does not have its own package. Instead it's the default, provided by the server
package.

When I want to specify modes via xrandr, my script goes in /etc/X11/xinit/xinitrc.d/setup when
using openSUSE or Fedora, /etc/X11/Xsession.d/95-setup when using Debian. My choice of setup or
95-setup to contain the xrandr script is arbitrary.
