Public bug reported:
I'm suffering from a problem where gnome-session pauses for a very long
time (90 seconds) during login. I type in my password to lightdm, the
screen switches to show my wallpaper, but nothing else, and for the next
minute and a half, I can't do anything besides move the cursor. Clicks
don't do anything, key combinations to start a terminal don't work. In
/var/log/syslog, I see a message
Jun 23 11:24:21 jun-MacBookAir gnome-session[1591]: gnome-session-
binary[1591]: WARNING: Application 'at-spi-dbus-bus.desktop' failed to
register before timeout
which seems to be caused by a problem with at-spi-dbus-bus.desktop, but
this bug report is not about that. The bug I'd like to report here is
that gnome-session's timeout is *way* too long. At first I had no idea
that the login was going to succeed at all, because it was frozen for so
long, and I kept rebooting by pushing the power button.
The 90-second wait seems to be hard-coded in the source, with a remark
that waiting long enough is critical on slower media like CD-ROMs.
While I can see how that's a concern, it makes no sense on a desktop
installation booting from the SSD. The long wait interferes with
debugging the problem (because every single thing I try takes at least
90 seconds), and will ensure that a problem in any of the components
like at-spi-dbus-bus.desktop will show up as a serious inconvenience. I
for one cannot stand a computer that takes minutes to boot, just because
one component is acting erratically.
Please make this timeout shorter if at all possible, or at least
configurable. Better yet, please have this automatically configured by
benchmarking the system upon installation.
In the meantime, I'm attaching a patch for anyone who wants a quick work
around to this nasty problem.
