Thanks

I remember dabbling with xorg.conf many many years ago, but now there is
no xorg.conf file anywhere in Kubuntu. Should I just add one in /etc/X11/ ?
Are you able to point me to a beginners guide? I couldn't find any
example xorg.conf files, or howto guides for nouveau.

And grep finds no 'identifier' string in Xorg.log.0.

TIA

Peter
