Archive-name: devuan-startx-newtty.patch

The following patch for Devuan ASCII restores the correct `startx'
behaviour of allocating the first free tty for X.

With the bundled `startx' version, Xorg is launched in the same tty
where `startx' is invoked; which is wrong, inconvenient and messy.
To name but one downside: once you quit X, the tty is no longer owned
by your user, but by root.

The current broken behaviour originated at RedHat as a kludge
for systemd component logind, and has no place in a distribution
devoid of systemd. You can read about the birth of the kludge
by following the http link found in the patch.

Xdevuan-startx-newtty patch by <dario@darioniedermann.it> 12-Sep-2018
X
X=== How to apply this patch ===
X
X# cd / && patch -p1 < /path/to/devuan-startx-newtty.patch
X
XThere is no need to trim any text, before or within the patch itself:
Xthe `patch' program knows what to skip.
X
X
X=== Part 1 ===
X
XA conditional is added to `startx' to check for the presence of systemd.
XIf the conditional fails, the nested block will not be executed.
XOn Devuan, that amounts to removing the 5 lines now encased
Xin the conditional.
X
XThose lines were responsible for passing `xinit' (and in turn `Xorg')
Xa 'vt' option followed by the current tty number. We must avoid that,
Xif we want a new tty.
X
XThe added conditional was copied from another systemd-less distro
X(VoidLinux, possibly it got there from somewhere upstream).
XI also comment out a '-keeptty' option that was in the Devuan version
X(but those lines are no longer being executed anyway).

X=== Part 2 ===
X
XThe Devuan 'Xwrapper.config' file wasn't setting the 'needs_root_rights' Xvariable. So, the patched `startx' would lack permission to allocate
Xthe first available tty, and it would fail - except when issued by root.
