Question about xorg.conf in dom0

[daltong defourne]

Hi!

Basically, I'd like to understand how Xorg in the dom0 is controlled/managed, because I do have a xorg.conf in dom0 at /etc/X11/xorg.conf (qubes r 3.2) but apparently other users do not (as I found out via qubes-issues discussion).

Options in xorg.conf  appear to be working (at least, I was able to break things via this file, and then fix by reverting to a backup copy of this file) but I'm now not sure "what is where and what takes precedence" so I decided to ask in the group with maximum concentration of people who actually know how it works on the inside

I have a similar question about X and keymaps -- I use xmodmap to
remap caps to control in dom0, which works and is inherited by all
of the other VMs. The other keymap remappings don't seem to take
effect in anything other than dom0 and I have to re-run xmodmap
in the guests.

By default there is no /etc/X11/xorg.conf in dom0, so I guess you've
created it yourself. There is nothing Qubes-specific in Xorg
configuration in dom0. Especially, if you create /etc/X11/xorg.conf, it
should be used by the X server.

On the other hand, in VMs Xorg have specific configuration.

See also files in /etc/X11/xorg.conf.d/
