A backtrace from gnome-shell would shed more light.

Interesting. The only difference here is, it's a desktop with 3 GB RAM, 
with a i945 instead of i915. Buggy opengl drivers probably.

 Already on gnome 3.4, unmasked from default portage, no overlay.

 Complete rebuild over with O2, still getting these errors:

I know "works for me" is basically useless, but my laptop is from
2008, a dual core 2.26 GHz with 4 GB of RAM, and an Intel Corporation
Mobile 4 Series Chipset Integrated Graphics Controller, i915 video
card.

As I said, works perfectly.

It seems I was using only gnome-shell 3.4 and did not update others.
Now I unmasked 3.4 completely (gnome-base/*, gnome-extra/*).
It's much more stable than 3.2, except for the two faults I pasted
above.

Watching this thing now for crashes, will post update soon.



And boo.. it crashed just after writing the previous mail. Upto 3
windows on the single workspace was good, with 4 it crashed. :|

No faults reported in dmesg though.

I'm compelled to concolude that GNOME3 simply does not work on 4-5 year 
old hardware. Yeah, on a Dual Core 2 Ghz, 3 GB RAM, and i945 128 MB.


I'm back to my cozy place, KDE and alsaequal (instead of pulseaudio).

I had lots of graphics related problems with gnome3.2 - from render
errors to system freezes. So in a desperate move I unmasked gnome3.4
(from the overlay) and installed it. Installing (and maintaining) 3.4 is
a bit hairy, but all my problems have gone since that.

So if recompiling with O2 does not help, and you don't mind bleeding
edge packages on your system, try 3.4

And what about segfaults in conftest and libglib? Happened sometime ago.
Http://bpaste.net/show/34833

Would a complete fresh install of gentoo do any good? There are still some
200+ packages left to build.

Also, can it be by chance a loose connection in some of the component?


I got a new adata ssd recently and this is getting bad now. Though it has 3
year warranty, but still I wanted to keep it as long as possible. With this
many number of writes it would die soon. Probably on 1 day past when the
3rd year ends as it usually happens.


I've got so addicted to gentoo's customization that it was even hard to
install arch from where I entered the world of rolling release distros.

Could be anything, actually. Perhaps the Southbridge (or whatever its nom
de jour is) which IIRC handles the sound system. (Because Pulseaudio is
also having trouble).

Yeah gnome shell. There are no traces about segfaults in dmesg for gnome
shell crashes. It happens whenever I open more than 3 windows in one single
virtual desktop (activity).

About pulseaudio, it works, but I always see segfault message from the
equalizer module in dmesg.

90% of NREs (Non Reproducible Errors) are caused by hardware problems.

MemTest, albeit a good and thorough diagnostic utility, only checks for
memory problem.

It is likely that some other component on the OP's mainboard is failing; a
component that lies outside the datapath exercised directly or indirectly
by MemTest.

By GNOME you mean, gnome-shell? Do the crashes occur randomly, or can
you reproduce them? Same with PulseAudio.

Have you tried don what this page instructs?

I've been using GNOME 3 since May last year. No major problems so far.

[gentoo-user] Random segfaults with gnome

[Nilesh Govindrajan]

Lately, ever since I installed gnome3 (3.2), a lot of things have gone
unstable. Gnome crashes a lot and pulseaudio too, on every start (I see a
segfault by the equalizer module).

My graphic card is on board i945 and I have set mesa to classic mode on sw
and i915 families.

I partially belive that this is because of -O3 in my make.conf, but
compiling a few packages using -O2 didn't do much good either. Moreover,
I've been using kde with -O3 since 2011 and never had such a problem.

Nevertheless, I'm rebuilding everything with -O2 (emerge -e system, emerge
-e world) with gcc 4.7 (no lto) just to see if that fixes the trouble.

I have memtested and there's absolutely no problem with the RAM.

What do you guys suggest?
