Re: [gdm-list] How to add command line options to Xserver?

[Ray Strode <halfline gmail com>]

Hi,

It's not possible to edit the command line arguments at the moment.

Of course, GDM won't function in a well defined way if the X server
isn't started in a well defined way.   And at some point the future,
wayland could get thrown into the mix complicating things even more.

Generally if someone wants to modify the command line arguments, they
want to do that as a mechanism to solve a specific problem.  What
problem are you specifically trying to solve? For instance, if the
problem is "log verbosity isn't high enough" we can bump the log
verbosity (we did this infact recently in git in response to someone
asking about it).

As a short-term, "right now" solution, there's the shell script wrapper hack:

mv /usr/bin/Xorg /usr/bin/Xorg.binary
cat << EOF > /usr/bin/Xorg
exec /usr/bin/Xorg.binary "$@" -other-option-here
EOF
chmod +x /usr/bin/Xorg

The whole idea of server configuration is also closely tied with
support for multiple "seats", which we've looked into in the past but
haven't come up with anything landable yet.  See:
