I don't know how it would have gotten in there... but if something
indirectly runs xrandr(1) as part of your shell startup, that could do it?

The startup files that bash could use are in:
man bash | less +/^INVOCATION

You could confirm if /usr/bin/xrandr gets called with execsnoop(8)
(Debian/Ubuntu package perf-tools-unstable ; or as found from:
https://github.com/brendangregg/perf-tools 
or:
http://www.brendangregg.com/ebpf.html
https://github.com/iovisor/bcc
)

It's possible that the RandR code is being called from elsewhere,
e.g. via DBUS calls, which could be spotted with dbus-monitor ?
