Re: simplest way to convert to xlibre
Reply #3 –
I executed the command recommended and it gives me the following (I had to remove lxdm which needs xorg-server)
$ pacman -Q | grep '^xorg-server-\|^xf86' | cut -d' ' -f1 | sed 's/^xorg-server-/xlibre-xserver-/' | sed 's/^xf86-/xlibre-/' | sudo xargs -ro pacman -Syy

Errors occurred, no packages were upgraded.
so I guess the xlibre packages don't object to xf86-input-libinput, xf86-video-fbdev & xf86-video-vesa.
I removed the conflicting pkgs and then entered
sudo pacman -S xlibre-input-libinput xlibre-video-dummy xlibre-video-fbdev xlibre-video-intel xlibre-video-vesa xlibre-xserver-common xlibre-xserver
this command worked without any clashes and a reboot allowed things to proceed. Everything seemed to be working 
One thing I noticed is that artist's command doesn't seem to install xlibre-xserver; I added that to the end of the discovered list myself.
