Interesting, the screenshot looks like when you have a secondary monitor set
"on the right" of the one you are using.
That's it! To explain: I have only one physical monitor, but it's connected twice,
once to the internal GPU (Intel) and once to an Nvidia card which is for a Windows VM
passthrough (i.e. the VM has direct access to the Nvidia card without mediation from
Linux). Passthrough only works when the nvidia module is not loaded (the second GPU cannot
be shared between host and guest), and this was the case before I rebooted, but then on
reboot the akmod script has reinstalled it. The result is that Linux is seeing both
connections and logically assuming they are distinct monitors.
Looks like I'll have to remove the akmod stuff completely to stop this
Good catch, thanks.
