Hello,

unfortunately, never versions of sddm ignore the "MinimumVT=" flag in "/etc/sddm.conf" by intention. Hence, sddm starts on vt2 instead of vt7 (I use OpenRC). On the other hand, one can restart sddm via "/etc/init.d/display-mananger restart" and then it starts on vt7.

I assume that this is, because at the moment that "/etc/init.d/display-mananger" starts the first time at boot, agetty has only established tty1 on vt1 and therefore sddm uses vt2.

Later, if one restarts "/etc/init.d/display-mananger" agetty has established all tty 1-6 on vt 1-6 and therefore sddm can only use vt7.

So my question is: Has anyone an idea to circumvent that problem / Is there a method that agetty establishes all tty 1-6 before "/etc/init.d/display-mananger" starts the first time?

Thanks in advance
GOS

I moved the terminal lines in /etc/inittab for tty 2 through 6 to after the boot command, but before the runlevel definitions.

I mentioned this a while ago when sddm went to >0.19, no one has told me "you shouldn't do that because" yet, and it restores the desired behaviour.
I might look at sddm again after a couple more updates, and see if the "new code" to set a minimum VT works yet, but it didn't when I checked 0.21.

It appears this can still be set at compile-time (IOW, works for me), like so.

@ Ralphred: This means, you placed the "#TERMINALS"-section directly under "rc::bootwait:/sbin/openrc boot"-line !?

@ steve_v: Where do you place this file? Is it a patch?

Yes, but I'll just drop the relevant bit here with context.
Code:
# Default runlevel.
id:5:initdefault:

# System initialization, mount local filesystems, etc.
si::sysinit:/sbin/openrc sysinit

# Further system initialization, brings up the boot runlevel.
rc::bootwait:/sbin/openrc boot

# TERMINALS

Steve is using /etc/portage/env, so you could use
/etc/portage/env/sddmfix:
MYCMAKEARGS="-DSDDM_INITIAL_VT=7"
and
/etc/portage/package.env/sddm:
x11-misc/sddm sddmfix

@Ralphred: Thanks a lot. Your approach worked for me. I tested also Steve's approach, but that did not work.

One day it will; the sddm devs had to re-write the vt allocation code, the outlier use cases for which it doesn't work will get fixed, the code will become stable, and we'll probably(?) end up with a "minvt7" use flag.
