xf86config.py:453 sets the monitor name to "Generic Monitor"
if it can't detect the monitor using DDC. This causes two
monitor sections with the same name to be generated, and the
settings set in kickstart go into the second section. X
pays attention to the first one. They need different names.
Workaround: run Xconfigurator --kickstart in %post section.
