I’m trying to use different configurations on my laptop :
- standard linux kernel with proprietary nvidia driver
- and Xen to allow developping/testing in a hosted dom-U Debian distro, in which case I switch back to the libre
nv
driver
When using the proprietary nvidia driver, I may use two kind of configurations :
- having several screens in “clone” mode, i.e. replicated view on screen and beamer, for instance (classical use of Fn+F8 clone display)
- or having both screens assembled into one to use twinview with dualhead, which provides (through Xinerama) and being able to switch windows from one to the other
This means I configured several layouts in the same xorg.conf
file, which will describe each a different Xorg configuration.
Update 2008/02/10 : reorganized that post to be able to manage kernel-passed LAYOUT variable
