I think for startx that's a fedora patch, I don't think that's upstream.
So maybe we should upstream it ?
With this patch-set + my systemd-logind patches I can login as user on a vt,
and do startx without needing a suid-root bit on my xserver.
There are only 2 minor issues left with running as non root after this:
1) One (harmless) error message about failing to get iopl rights
2) Currently my /var/log is writable by the user as which I start x
Solving 1) is something to do after I've figured out how we want to deal
with UMS when the xserver is not suid root
For 2), I'm thinking about just logging to the users home dir, so user hans
would get a /home/hans/.Xorg.0.log file. Input on this is much appreciated.
I'd be tempted to even skip logging to a file and log to stdout only. That
way whatever launches X can decide how to handle the log output,
specifically with a few minor changes in gdm we could make sure the output
ends up in the journal.
If we want to integrate nicely with the journal the easiest way would be to
just use syslog. But some people are going to dislike xorg spamming their
/var/log/messages
So maybe add syslog support + an option for selecting whether to use file
based logging or syslog + a ./configure option to set the default (file
or syslog) ?
And in the file case of /var/log/.... fails fall back to ~/.Xorg.#.log ?

Hans
