[SOLVED] LightDM broke GTK theme/settings, existing fixes don't work

lidavidm · 2012-03-04 18:28:56

Hello, I recently switched to Arch Linux from Ubuntu and am trying to get LightDM to work. I successfully installed it from the AUR, however, after doing so, my GTK theme broke and none of the settings in Gnome Tweak Tool (with the exception of Gnome Shell settings) are applied. I've been Googling for a while now, and found these threads:

https://bbs.archlinux.org/viewtopic.php?id=134019
https://bbs.archlinux.org/viewtopic.php … 45#p982145

I created a session wrapper as described at those links, but it leads to no change. For reference, my problems are:

No wallpaper
GTK theme not applied/partially applied, but looks ugly (as if I were the root user, which I am not)
Icon theme not respected
Preferences (e.g. keyboard settings) set in Gnome Control Center and/or Gnome Tweak Tool not respected

Packages I used:

lightdm-bzr
lightdm-unity-greeter
glib2-ubuntu (http://aur.archlinux.org/packages.php?ID=42521)
libindicator3 (http://aur.archlinux.org/packages.php?ID=57219)

(The last two were needed to get the greeter to build, but they weren't listed in the dependencies)

For reference, this is what Evince looks like:

Is there any other information needed?

Hello, since you linked to my post, i looked into it again. lightdm is actively developed, so I'm not sure if what i've said is still valid. From what you are describing, i would guess the gnome-session service are not launching as expected (e. g. gnome-settings-daemon is missing, like when just launching xinit /usr/bin/gnome-shell instead of xinit /usr/bin/gnome-session). To verify that, could you paste the output of something like

ps fax

while running gnome?

Also, could you show the session wrapper you created, ls -la on the said session wrapper to check permissions, your /etc/lightdm/lightdm.conf and the content of /var/log/lightdm/lightdm.log?

Thanks for helping!

Here is the information requested:

ps fax: http://pastebin.com/9GGMaSu7

There is one instance of gnome-settings-daemon, shouldn't there be two?

/var/log/lightdm/lightdm.log: http://pastebin.com/rtkEcE89

My session wrapper:

#!/bin/sh
userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap
# merge in defaults and keymaps
if [ -f $sysresources ]; then
    xrdb -merge $sysresources
fi
if [ -f $sysmodmap ]; then
    xmodmap $sysmodmap
fi
if [ -f "$userresources" ]; then
    xrdb -merge "$userresources"
fi
if [ -f "$usermodmap" ]; then
    xmodmap "$usermodmap"
fi
# start some nice programs
if [ -d /etc/X11/xinit/xinitrc.d ] ; then
	for f in /etc/X11/xinit/xinitrc.d/* ; do
		[ -x "$f" ] && . "$f"
	done
	unset f
fi

[[ -f /etc/profile ]] && . /etc/profile

exec ck-launch-session gnome-session

And the permissions:

$ ls -la xinitrc
-rwxr-xr-x 1 root root 847 Mar  4 12:33 xinitrc

Actually, I can definitely say that it is a problem with gnome-settings-daemon. Running this fixes the look-and-feel, though I still can't get the settings to apply:

$ sudo /usr/lib/gnome-settings-daemon/gnome-settings-daemon

For some reason it isn't on the PATH. I tried the first two fixes listed at http://askubuntu.com/questions/21305/de … gets-theme, however, that causes GNOME to fail with an error (and X says that the service failed to register itself before the timeout). However, GNOME still ignores my icon theme, GTK theme, and wallpaper, among other settings, instead reverting to the default Adwaita (though it does respect my Metacity/Mutter theme).

Unfortunatly I can't reproduce this problem here. I've read through the links you posted, and somewhere it was suggested it's in fact not a configuration issue, but a race condition in lightdm or g-s-d, so i would not be of much help then.

Though, I wonder what your exact setup is, since you said you are using lightdm-bzr with lightdm-unity-greeter, but the latter actually depends on lightdm-ubuntu.

For some reason it isn't on the PATH

That's alright I guess, it seems to be a recent trend to move binaries out of /usr/bin/ if they are not supposed to be launched interactively.

P. s.:
-To eliminate the simple causes, the Gnome Settings Daemon is enabled in the gnome-session-properties, right?
-On some of the launchpad bug report it was suggested this issue might be related to proprietary video drivers. Though it sounds unlikely, are you by any chance using the nvidia driver? Does the problem persist using the nouveau ones?

Yes, the AskUbuntu topic was about a possible race condition - it doesn't help, unfortunately.

I modified the PKGBUILD so that lightdm-bzr and lightdm-unity-greeter would work together, I hope that didn't cause any problems...

GSD is enabled in gnome-session-properties, and I am using the open Radeon drivers, so I don't believe those are the causes. I removed LightDM and reinstalled Gnome, etc. to see if that would resolve the issue, but unfortunately, it still doesn't work...

Actually, I solved it. I removed all of my config files in my home directory. Some setting messed up GNOME along the way...

Thanks for helping!
