Multiple monitors on linux
I am using a special configuration of monitors on some computers with two monitors. On old setup with NVidia graphics card I used xorg.conf with two screens setup. I was able to start different windows managers on each monitor, because one was DISPLAY :0.0 and another was DISPLAY :0.1.
Now I try to migrate from CentOS5 to CentOS7 and also computers have onboard Intel graphics instead of NVidia.
Whatever I try I only get DISPLAY :0.0. xdpyinfo says that the number of screens is 1 and dimensions of that screen are combined dimensions of both monitors.
There is no more xorg.conf in CentOS7. I would rather use /etc/X11/xorg.conf.d/ directory where I could put parts of xorg.conf, which are special.
How could I start xorg in that way that each separate screens and not one combined display? I want screens :0.0 and :0.1.
I used some xrandr commands to rotate one of the screen, etc. Can I add as display with xrandr?

I usually just use something likexrandr --output DP2 --mode 1920x1200 --above eDP1, where eDP1 is my laptop's screen and DP2 is the external monitor.

I have no problems displaying graphics on both screens. I want them to be separate screens (:0.0, :0.1) to be able to run different windows managers on them and that windows could not be moved from one screen to another. I have tried xrandr commands as you suggested and they do not provide what I need.

Oh, I see. Unfortunately, I've never tried that with xrandr :-(

I used ZaphodHeads option a while ago and I don't know whether this still works. I will try it.

I have found a solution here https://askubuntu.com/a/419614/217214. There is one thing to be careful of. xrandr reports HDMI-1, HDMI-2 and eDP-1 outputs on my graphics adapter. However, I had to use HDMI1, HDMI2 and eDP1 in xorg.conf file.
I did not use /etc/X11/xorg.conf file. I added a file 20-screens.conf to /etc/X11/xorg.conf.d/ directory. The file is very similar to the one provided in the solution https://askubuntu.com/a/419614/217214. So I don't see the point of repeating it here.
