Problems installing sway / wayland

[Senpai]

Hello!

Disclaimer; although I'm not new to Linux, and I've been using Arch for a long time now, this is my first time in Gentoo, and I've decided to up my game, so for the first time I'm trying to set an ideal developer environment, and hopefully learning some while doing so. For that reason, I've decided to go with no-multilib minimal setup and to install and configure everything that I need, so hopefully, by the end of the process, I'd learned how my environment works, while also having the best possible slim and performant environment for me to play in.
That mostly involves me googling a lot of stuff, and learning as I go, but for this particular issue - I could find no obvious answers. I'm sure I'm missing something obvious, but please be gentle with me.

Background
I'm having issues setting up sway and wayland. I've setup up, DBus, elogind, my bashrc profile to export XDG_RUNTIME_DIR, but even still I'm having the same issue, and it doesn't seem to lead me anywhere useful.
The machine is a lenovo laptop, and is using an AMD APU - Ideapad 5 - 15ARE05.

Sway, or rather wlroots, tries to communicate with elogind, while you have seatd installed.
I remember I needed to add elogind to boot runlevel to make wayfire (wayland compositor which also uses wlroots) start.

So I'd probably disable seatd completely and then add elogind to boot runlevel.
Also if you didn't meant to have seatd, you could then uninstall it. First check your use flags if something is pulling seatd for some reason.

 - - elogind : Enable session tracking via sys-auth/elogind
 + + server  : Enable standalone seatd server 
 - - systemd : Enable use of systemd-specific libraries and features like socket activation or session tracking

If you are going to have both seatd and *logind, then set the flags properly for seatd.

Edit to add: and since you don't have dbus started, you might add

Code: Select all

dbus-run-session -- /usr/bin/sway

or however you are trying to start sway.

Hello Guys, thanks for the help.

So I had a look;

Sway, or rather wlroots, tries to communicate with elogind, while you have seatd installed.
I remember I needed to add elogind to boot runlevel to make wayfire (wayland compositor which also uses wlroots) start.

So I'd probably disable seatd completely and then add elogind to boot runlevel.
Also if you didn't meant to have seatd, you could then uninstall it. First check your use flags if something is pulling seatd for some reason.

It seems that sway itself pulls in seatd for some reason, although I don't see any specific USE flags for sway itself to toggle this behaviour.

Code: Select all

# equery depends seatd
 * These packages depend on seatd:
gui-libs/wlroots-0.15.0-r2 (sys-auth/seatd)
gui-wm/sway-1.7 (sys-auth/seatd)

From random forums online, and the comments here would make me believe that elogind is the preferred approach, and I shouldn't need seatd with that being installed.
Is that correct?

I remember reading online, that I don't have to add elogind to boot runlevel, or have it running as a deamon at all.
Your comment seems to suggest otherwise, so I'll try doing so, see if that fixes my issue.

$ equery u seatd

dbus-run-session -- /usr/bin/sway

or however you are trying to start sway.

First of all, my bad, I forgot to say that I'm trying to run sway with `dbus-run-session sway`.
As I mentioned above, for some reason I'm having a dependency on sway, so I don't seem to have a choice of having it installed at a time.
It's possible that I'm being a donkey here, as I'm just learning emerge / and USE flags in general, but should I need extra steps to somehow mask seatd to prevent it from being installed with sway?

What is the ideal setup here? Should I get rid of elogind? Or seatd (somehow)?

I must admit, I'm completely out of my element here, although this is a good learning opprtunity for me, I can imagine this being frustrating for you guys. For this I'm so sorry. :/

[Anon-E-moose]

If you build seatd with the elogind use flag, it should work.

[Senpai]

If you build seatd with the elogind use flag, it should work.

I'm afraid that it was built with elogind USE flag. It's in my make.conf.

as Anon-E-moose how are you starting sway?
you state: dbus-run-session sway which is good but what about the services you have running and the ENV you have setup?

dbus-run-session  sway $@

I technically start sway via greetd but that is a by and by

I've followed the wiki, and that mentions setting up XDG_RUNTIME_DIR only (unless I missed something), so that's being exported by my bash_profile

Code: Select all

# /etc/skel/.bash_profile

# This file is sourced by bash for login shells.  The following line
# runs your .bashrc and is recommended by the bash info pages.
if [[ -f ~/.bashrc ]] ; then

fi

if test -z "${XDG_RUNTIME_DIR}"; then
	export XDG_RUNTIME_DIR=/tmp/${UID}-runtime-dir
	if ! test -d "${XDG_RUNTIME_DIR}"; then
		mkdir "${XDG_RUNTIME_DIR}"
		chmod 0700 "${XDG_RUNTIME_DIR}"
	fi
fi

As when it comes to rc services that are running, seatd is running, elogind is not, as I've read that it doesn't have to. Nonetheless I've tried running sway while it was running as well - but to no avail.

In terms of the env, the bash_profile seems to work, and it seem to export the XDG_RUNTIME_DIR ENV properly.

[Anon-E-moose]

Try with
dbus-run-session -- sway
instead of
dbus-run-session sway

Though not 100% sure if that will make a diff.

Edit to add:

grep video /etc/group
should return group,
if your userid is not there then as run as root with $USER being your username
usermod -G video -a $USER

Code: Select all

 $ grep video /etc/group
video:x:27:root,owner

ETA2: Setting this might help

.

The problem with the wiki is it is a snapshot of valid information but that does not mean it is the complete picture.

XDG_RUNTIME_DIR is needed but how you set it is different.
1) via such a snippit you have in bash
2) elogind

I originally was doing what you were doing when I was using lightdm+awesomewm BUT aspects of pipewire caused some issues so I reverted to elogind. So when I then went wayland+sway it was smoother

I can confirm all that Senpai said. The Gentoo wiki of sway is a bit outdated (at least for openrc not systemd since I haven't tried) for its default way to launch sway just after login, and even by typing "dbus-run-session sway" . Editing the /usr/share/wayland-sessions/sway.desktop as CooSee said and launching sway with any display manager can work, using greetd like Naib said can also be done with this modification.

I don't know everything about linux, but I tried many things to launch sway from tty or just after login in tty like said in the wiki. The only way I succeeded to launch sway with a modification (similar) of .bashrc like the wiki of sway says :

Code: Select all

if [ -z "$WAYLAND_DISPLAY" ] && [ -n "$XDG_VTNR" ] && [ "$XDG_VTNR" -eq 1 ] ; then
    exec dbus-run-session sway
fi

is to use the display manager qingy ( https://wiki.gentoo.org/wiki/Qingy ) by selecting "console" in the display manager choice. Remember qingy needs modification of /etc/inittab like its wiki of qingy says. I have no idea why it works by changing agetty for qingy.

I don't know everything about linux, but I tried many things to launch sway from tty or just after login in tty like said in the wiki. The only way I succeeded to launch sway with a modification (similar) of .bashrc like the wiki of sway says :

Code: Select all

if [ -z "$WAYLAND_DISPLAY" ] && [ -n "$XDG_VTNR" ] && [ "$XDG_VTNR" -eq 1 ] ; then
    exec dbus-run-session sway
fi

In my opinion .bashrc is the wrong place because this file is evaluated for every bash session. Better put it into .bash_profile or .bash_login or .profile so that it is evaluated only once.
