fixed the gnome forever-suspend problem

fixed the gnome forever-suspend problem

[Andy Wingo]

Hi!

Just a quick note that the elogind update I just pushed fixes the GNOME
suspend problem.  (Used to be, from GNOME if you close your laptop lid
it suspends fine, resumes fine, but then immediately suspends again --
forever.)  It was an elogind bug.  GNOME by default inhibits logind from
suspending using the "delay" inhibit mode, meaning that the suspend is
delayed until GNOME comes back to it.  If GNOME never comes back to
elogind, the suspend will happen after 5 seconds anyway.  Elogind emits
a signal indicating that it wants to suspend, causing GNOME to do
whatever it needs to do (maybe logging you off your IRC or so, dunno)
and then removes its suspend inhibitor, allowing elogind to suspend.
This code path is a little more complicated than the way an XFCE session
was suspending, which had no inhibitor / etc and logind handled it
itself.

Anyway!  Give a try to GNOME, it seems to be an OK environment.
NetworkManager doesn't work by default yet -- I think we're missing the
service -- so you have to still use the wicd control panel.  I think
something's not working with media keys either; some daemon not running
yet.  Otherwise though GNOME seems to work OK, just as fine as XFCE
anyway.

Andy

ps. Although because the media keys aren't working right now, the
brightness keys don't work, you can change the brightness via the GNOME
control panel, which means that the pkexec + polkit + logind + pam +
sudo waltz seems to be working fine :)

pps.  To try GNOME, add (gnome-desktop-service) on to your services:

(operating-system
 ...
 (services (cons* (gnome-desktop-service)
                  (xfce-desktop-service)
                  %desktop-services))
 ...)

Then choose it using "F1" from the SLIM login window.

This works a charm for me: happily using Gnome with lid controlled
suspend now :D

It's amaaaazing :-)

Actually, for me the media keys and the screen brightness keys are
working fine, so I can confirm that all seems proper! :-)

Woohoo, awesome!  Looks like it wasn’t a trivial thing to debug…

Thank you!

Re: fixed the gnome forever-suspend problem

Hello!

I'm afraid that my experience was not so good on my libreboot +
MacBook2,1 system.  Previously, I also had the forever-suspend problem
in Gnome 3 while it was working fine in Xfce.  After building from
master a few hours ago, however, I was faced with a black screen and was
forced to do a hard shutdown.

Now, the manual shutdown appears to have corrupted the file system on my
fully encrypted disk because libreboot's GRUB fails to decrypt the
drive.  More precisely I get the following error:

> Failed to decrypt master key.
> error: access denied
> error: disk `crypto0' not found.
> error: you need to load the kernel first.

Fortunately I didn't have any valuable data on the disk.

Regarding the media keys I could make the following observations before
the system became unbootable:

* Brightness controls didn't work in GNOME's control panel logged in as
user.  It did worked when logged in as root however.
* Brightness controls worked in Xfce.
* Resume after suspend had stopped working in Xfce after having worked
before the more recent power-management commits.
* In the same manner sound controls had stopped working in Xfce.
* Audio controls were working in GNOME.

It's amaaaazing how things can break some times :)

Anyway, I hope the above information will be of some use in the future.
 I will now install Parabola on the MacBook2,1 but keep GuixSD on my
desktop computer.

Happy hacking!

Albin

Hi!

Sorry things didn't work for you.  Beta software, etc etc.

I had this problem until I uninstalled gnome-settings-daemon from my
user profile.  I am not certain that this was what caused things to
start working but I think it is.  I think it is related to which
services get chosen for d-bus or for execlp; not sure.  It could be your
user profile was out of date.  I do not know.

FWIW everything now works for me, which is a first in a year :)

\o/

I wanted to give it a try in a VM, hence these commits:

  6cbc8d5 * gnu: gnome: Disable hardware acceleration check via 'gnome.desktop'.
  c510cbb * services: xorg: Accept session commands with arguments.
  a0d7baa * gnu: gnome-session: Make sure 'gsettings' is found.

Now it works well in QEMU.

There are details to smooth out, such as having the right fonts
installed by default.  When I logged in, I got not-so-nice fonts in the
top-level bar, including squares here and there:

Ideas?

There’s also the problem of the default background, as you pointed out
before, but maybe that’s more “involved.”

Thanks for the great work on GNOME!

Thank you! Jan and I suffered with this for a while :)

I have the same issues with the squares (in the clock). Any advice?

For me it also introduced a new desktop environment affected by
bug#22985, all in all it awesome to have GNOME now, thanks!

Maybe we could package a gnome-artworks to include a broader
choice of backgrounds, and one like gnome-styles or whatever to
include other stylistic things.

I *guess* that might be font related. I don't have these issues, my

I’m happy to say this is now fixed.  :-)

The relevant commits are:

  e71ef7a * system: Make sure fonts are searched for in the system profile.
  0bd3597 * gnu: gnome: Add dependency on font-abattis-cantarell.
  4e8b750 * system: Allow account skeletons to be directories.
  71be99b * gnu: Add font-abattis-cantarell.

Turns out gnome-shell.css refers to Cantarell, the font specifically
designed for GNOME 3.  Furthermore, our Fontconfig package does not look
for fonts in the system profile, which e71ef7a works around.
