 Posted: Wed Oct 19, 2016 6:47 am Post subject: Does pantheon work in gentoo? |
 |
|
Hello,
After a long hiatus I I've decided to try going back to using Linux as a desktop system. Gentoo seems like the only option I enjoy (been running it on servers and as a desktop before).
I had a brief look at desktop environments out there and it seems pantheon looks pretty promising, the questions are:
- does Pantheon work on Gentoo (does anyone here run it as a daily driver DE)?
- does Pantheon really depend on systemd ? While trying to emerge pantheon-shell, systemd got pulled in resulting in conflicts and I'm using openrc at the moment. Is it a hard dependency pulled somewhere from gnome world or is there a way around it? If the answer is no then I guess I have to switch from openrc?
Thanks,

charles, the ebuild is quite unhelpful. A better hint would have been to emerge with the "--tree" option, so portage displays what actually pulls in what.
However, I've added the elementary overlay and tried for myself: | Code: | # emerge --pretend --tree pantheon-shell
(...)
The following USE changes are necessary to proceed:
(see "package.use" in the portage(5) man page for more details)
(...)
# required by sys-apps/systemd-231::gentoo
# required by gnome-base/gnome-settings-daemon-3.20.2::gentoo
# required by pantheon-base/pantheon-shell-0.3_pre::elementary
# required by pantheon-base/pantheon-shell (argument)
>=sys-apps/dbus-1.10.12 systemd
(...) |
So at a first glance, gnome-base/gnome-settings-daemon seems to be the culprit. | Code: | # grep systemd /usr/portage/gnome-base/gnome-settings-daemon/gnome-settings-daemon-3.20.2.ebuild
inherit autotools eutils gnome2 python-any-r1 systemd udev virtualx
# systemd needed for power and session management, bug #464944
!openrc-force? ( sys-apps/systemd )
if ! systemd_is_booted; then
ewarn "You are enabling 'openrc-force' USE flag to skip systemd requirement," |
Oh, that looks promising... But the flag is masked, so you have to unmask it first and then try again, now showing a tree of packages, although it still wants systemd: | Code: | # echo "-openrc-force" >> /etc/portage/profile/use.mask
# USE="openrc-force" emerge --pretend --tree pantheon-base/pantheon-shell
(...)
[nomerge ] pantheon-base/pantheon-shell-0.3_pre::elementary USE="lightdm screensaver"
[nomerge ] x11-wm/gala-0.2.0::elementary
[nomerge ] pantheon-base/plank-0.10.2::elementary USE="dbus -debug nls -static-libs"
[ebuild N ] x11-themes/plank-theme-pantheon-0.1::elementary 15 KiB
[ebuild N ] pantheon-base/plank-0.10.2::elementary USE="dbus -debug nls -static-libs" 951 KiB
[ebuild N ] x11-wm/mutter-3.20.3::gentoo USE="introspection kms {-test} wayland" 1.454 KiB
(...)
[nomerge ] x11-wm/mutter-3.20.3::gentoo USE="introspection kms {-test} wayland"
[nomerge ] sys-apps/systemd-231:0/2::gentoo USE="acl -apparmor -audit -cryptsetup -curl -doc -elfutils gcrypt -gnuefi -http -idn -importd kmod lz4 lzma -nat pam (policykit) -qrcode seccomp (-selinux) ssl -sysv-utils {-test} -vanilla -xkb" ABI_X86="-32 (64) (-x32)"
[ebuild N #] sys-apps/gentoo-systemd-integration-6::gentoo 63 KiB
[ebuild R ] sys-apps/dbus-1.10.12::gentoo USE="X -debug -doc (-selinux) -static-libs systemd* {-test} -user-session" ABI_X86="32 (64) (-x32)" 0 KiB
[ebuild N #] sys-apps/systemd-231:0/2::gentoo USE="acl -apparmor -audit -cryptsetup -curl -doc -elfutils gcrypt -gnuefi -http -idn -importd kmod lz4 lzma -nat pam (policykit) -qrcode seccomp (-selinux) ssl -sysv-utils {-test} -vanilla -xkb" ABI_X86="-32 (64) (-x32)" 4.308 KiB
(...) |
So it looks like this:- pantheon-base/pantheon-shell pulls in x11-wm/gala
- x11-wm/gala pulls in x11-wm/mutter
- x11-wm/mutter pulls in systemd
The only option left is to go looking whether something there is optional: | Code: | # grep x11-wm/gala /var/lib/layman/elementary/pantheon-base/pantheon-shell/pantheon-shell-0.3_pre.ebuild
x11-wm/gala |
That one is fixed. Okay, it is Pantheon's Window Manager, so no surprise here. | Code: | # grep x11-wm/mutter /var/lib/layman/elementary/x11-wm/gala/gala-0.2.0.ebuild
>=x11-wm/mutter-3.8.4 |
That one is fixed, too. It is needed for compositing, so it does not really surprise me. | Code: | # grep sys-apps/systemd /usr/portage/x11-wm/mutter/mutter-3.20.3.ebuild
sys-apps/systemd |
Oh? Being shifted to the right is a hint, that this one is optional: | Code: | # grep -A 2 -B 5 sys-apps/systemd /usr/portage/x11-wm/mutter/mutter-3.20.3.ebuild
kms? (
dev-libs/libinput
>=media-libs/clutter-1.20[egl]
media-libs/cogl:1.0=[kms]
>=media-libs/mesa-10.3[gbm]
sys-apps/systemd
virtual/libgudev
x11-libs/libdrm:= ) |
Sooooo... If you can live without kms and wayland (which needs kms) support, systemd is not needed? | Code: | # echo "x11-wm/mutter -kms -wayland" >> /etc/portage/package.use/test_pantheon
# USE="openrc-force" emerge --pretend --tree pantheon-base/pantheon-shell
(...)
WARNING: One or more updates/rebuilds have been skipped due to a dependency conflict:
pantheon-base/plank:0
(pantheon-base/plank-0.11.2:0/0::elementary, ebuild scheduled for merge) conflicts with
<pantheon-base/plank-0.11 required by (x11-wm/gala-0.2.0:0/0::elementary, ebuild scheduled for merge)
^ ^^^^ |
Great. That overlay seems to be in quite a state...
So we have to try again with the gala live ebuild, as pantheon-base/plank-0.11.2 is marked stable, or we could try with masking plank-0.11.2. | Code: | # echo "=x11-wm/gala-9999 **" >> /etc/portage/package.accept_keywords/elementary
# USE="openrc-force" emerge --pretend --tree pantheon-base/pantheon-shell
(...)
( list of packages here )
(...)
Total: 65 packages (61 new, 2 in new slots, 2 reinstalls), Size of downloads: 159.386 KiB |
So, that's it, Pantheon without systemd.
I haven't tried with masked pantheon-base/plank-0.11.2, but you should now know how to analyze and solve such things.

Thank you very much for the analysis. The fact that gnome has a hard dependency on systemd without an alternative is concerning, but well maybe it's time for me to bite the bullet and cross to the dark side 
Will try to set up pantheon tonight and report back in case anyone's interested.

Everything you need to know about the state of GNOME with and without systemd and options for running it can be found here.
The short of it is that you can use Pantheon with or without systemd, however, if someone didn't do the work for you, you are going to have to do it yourself.
GNOME Without Systemd + Pantheon as suggested by charles17 is an option.
GNOME in "basic" OpenRC mode + Pantheon as suggested by Yamakuzure is also an option.

This works too (you Rebel scum  ).

Thanks for the links, I've read a little bit about the whole systemd drama and find it pretty interesting.
I tried running pantheon, but for whatever reason it seems to be broken (the plank 'dock' shows up but the rest of the screen is black. Most likely it is a configuration issue (not running some services that are required?) or did not emerge some required packages. Decided to give KDE a try, but did not like it that much (the interface did not seem to be very polished, there were weird lags and glitches). Eventually installled Gnome and like it so far. I think it looks and feels pretty good (some things are obviously copied from macOS, but in that case its a good thing) and so far I am happy with it.
Thanks for all the info.
