I have done the above: removed xorg.conf and placed a copy of the log
file at:


The output of xrandr is:

$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0xc3 cap: 0x7, Source Output, Sink Output, Source Offload crtcs: 4 outputs: 2 associated providers: 0 name:nouveau
Provider 1: id: 0x64 cap: 0x7, Source Output, Sink Output, Source Offload crtcs: 2 outputs: 3 associated providers: 0 name:nouveau

but only two monitors are found/configured.

Any pointers on how to do this would be welcome.
