[SOLVED]gtk3 apps slow start

Hello,

Got a problem with gtk3 apps (evince, gedit, gtk3-demo etc.): the start of the apps is painfully slow - around half minute. Can't really tell since when this is started.

First of all, started straced evince "strace -r evince" and noticed what was taking so long:

     ...
     0.001237 poll([{fd=11, events=POLLIN}], 1, 25000) = 1 ([{fd=11, revents=POLLIN}])
     0.000245 read(11, "\1\0\0\0\0\0\0\0", 16) = 8
     0.000031 poll([{fd=11, events=POLLIN}], 1, 24999) = 0 (Timeout)
    25.024476 write(11, "\1\0\0\0\0\0\0\0", 8) = 8
     0.000231 futex(0x55a56dbf7a30, FUTEX_WAKE_PRIVATE, 2147483647) = 0
     0.000197 close(11)                 = 0
     0.002580 write(6, "\1\0\0\0\0\0\0\0", 8) = 8
     ...

Honestly: can't tell anything from this output (even after reading some "man 2 poll"), but I hope that this will help someone.

What I tried:
Deleted everything from ~/.config/gtk-3.0/
Deleted ~/.cache/ folder
Downgraded video drivers.

However, noticed that running apps as superuser "sudo evince" - it starts as quick as it should.

I do assume that there is something obvious that I'm missing, and asking Your help.

Thank You for reading the problem. If there is something unclear or You need more information about anything else, feel free to ask. Seriously. Any thought also would help.

Re: [SOLVED]gtk3 apps slow start

Please post (link to) the full strace as that excerpt is far too limited - most notably, you have trimmed the opening of file descriptor 11, so it's not clear what file (or file-like) that is waiting on.  But as a wild guess, I'd suspect it might be a theme-related input.

Re: [SOLVED]gtk3 apps slow start

That strace doesn't include fd 11 and is interrupted before reaching it, so it's not the same strace and we've no indication whether or where it stalls.

Re: [SOLVED]gtk3 apps slow start

Yes, it is different strace than I mentioned in the #1 post.
The strace in #3 post is just another one. The last line was the one causing "timeout", so pressed ^C. 

poll([{fd=8, events=POLLIN}], 1, 25000^C) = ? ERESTART_RESTARTBLOCK (Interrupted by signal)

My bad - I should have mentioned it.

Re: [SOLVED]gtk3 apps slow start

It's waiting for some event notifier (which it has just read, though) - could be dbus.
What's the output of

loginctl session-status

Does this also happen to eg. gtk3-demo?

Re: [SOLVED]gtk3 apps slow start

State: closing

Bad. Also that's no graphical session?

Re: [SOLVED]gtk3 apps slow start

No, there is graphical session. Running awesomewm. .xinitrc :

nm-applet &

# Make sure this is before the 'exec' command or it won't be sourced.
[ -f /etc/xprofile ] && source /etc/xprofile
[ -f ~/.xprofile ] && source ~/.xprofile
[[ -f ~/.Xresources ]] && xrdb -merge -I$HOME ~/.Xresources

exec awesome

Tried running again the command again it's active:

$loginctl session-status

But, yea, nice catch. Not really sure why the status was closing.

EDIT:
Rebooted the PC and the state is still active. Not sure how it was closing. The problem still exist.

Re: [SOLVED]gtk3 apps slow start

You're missing a vital section from your ~/.xinitrc that means your session isn't being started correctly, read...
https://wiki.archlinux.org/index.php/Xinit#xinitrc

Not sure if this is the cause of your problem but it needs fixing either way.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Yes it is! Finally, now the system call doesn't timeout anymore.
I can't believe I made mistake in a such place.

Adding the default section in .xinitrc solved it. Now .xinitrc looks:

nm-applet &

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/?*.sh ; do
  [ -x "$f" ] && . "$f"
 done
 unset f
fi

# Make sure this is before the 'exec' command or it won't be sourced.
[ -f /etc/xprofile ] && source /etc/xprofile
[ -f ~/.xprofile ] && source ~/.xprofile
[[ -f ~/.Xresources ]] && xrdb -merge -I$HOME ~/.Xresources

exec awesome

Thanks, Trilby, seth and Slithery.

Re: [SOLVED]gtk3 apps slow start

With a recent gtk3 update, I had a similar issue. As noted by Slithery, the issue was that I didn't source the files from /etc/X11/xinit/xinitrc.d and in my case, the crucial file to source was

/etc/X11/xinit/xinitrc.d/50-systemd-user.sh

which adds DISPLAY/XAUTHORITY environments to the system user session.
