No, Google just likes to increase their version numbers in big steps so
that you think that they make quick progress. v11.2.202.559 on Linux is

In my experience, at least evince is great with forms! Since that's

handle them nicely as well. [The only reason to keep acrobat around are
some documents with PDF comments filled out by people on Macs. evince

Are you sure that diving right into about:config is the best way? In
SeaMonkey, take a look under Preferences -> Privacy & Security ->
Certificates. Under "Manage Certificates..." you can import your own
certificates which I think is the right way to proceed (although I
haven't tried that in a while). In the same dialog, you can also
manually add exceptions before you even go to the server.
Firefox and Thunderbird have similar dialogs.

Dear all,

after successfully using kernel 4.0.5 (vanilla-sources) for a while, I

them. On the screen I see

   Decompressing Linux... Parsing ELF... done.

as the last thing, then it just sits there.

To upgrade I copy the previously used .config to the new kernel
directory and run genkernel with --no-clean and --menuconfig so that I
get the same config as before -- unless I change something, which in
this case I didn't. (This has worked very nicely since 3.1.x or so).

If you can use it, use it. OpenMP is little more than a set of

instructions available to x86 still goes on.


I guess this is just poorly phrased but to clarify: OpenMP *does* use
multithreading and nothing else. It does not, in any way, make more 
use
of vector instructions than GCC without -fopenmp. I guess what you

the like.


To get GCC to try and use vectorization pass -ftree-vectorize.

[gentoo-user] Recent networking problems

[Peter Weilbacher]

Hi all,

since about two weeks I have been fighting with networking problems on 
a laptop. It all started with a big sync  world update that gave me new 
udev-171-r5, wicd-1.7.1_pre20120127, tuxonice-sources-3.0.17, 
openrc-0.9.8.2, among other things (I'm mostly running stable). Symptoms 
are that I cannot even get wired _listed_ in wicd, and when connecting 
to various different wireless routers, the connection died quickly. The 
e1000e driver (for wired) apparently never detects when a cable is 
connected, and when trying it through /etc/init.d/net.eth0, dhcpcd times 
out when waiting for a carrier... I tried alternating kernels (tuxonice- 
and gentoo-sources, both older and new ones between 2.3.38-r1 and 3.2.1) 
and kernel configurations as well as downgrades of several suspect 
packages, without success.


Does that ring a bell with someone? Any advice how I can track down 
these problems?


Cheers,
   Peter.

[gentoo-user] wicd fails to set wireless connection

[Peter Weilbacher]

Since yesterday I cannot use wicd any more to get a wireless connection (wired
still works fine). I think this has to do with a dbus update, but I'm not sure.
I have done several restarts, re-emerged all relevant packages (dbus, 
dbus-python,
wicd) but still it stops shortly after clicking the connect button in the GUI
window, saying Disconnecting active connections... in the status bar (even 
though
no connections were active).

If I start wicd-gtk from the command line I sometimes get the errors below, but
often it just hangs. wicd-curses always fails reliably with the output below.
Does that ring a bell with someone?

Cheers,
   Peter.

 If you have emerged python recently and switched to 2.7, did you remember to 
 run python-updater?

No, I switched to 2.7 months ago and it has worked fine since then. I noticed
that python 2.7.2 also got installed yesterday, but reverting to 2.7.1-r1 does
not change the behavior or the message.
python-updater only complains about libreoffice-bin and emul-linux-x86-baselibs,
probably because they contain their own binary copies of some non-2.7 python
stuff.

 I have done several restarts, re-emerged all relevant
 packages (dbus, dbus-python, wicd) but still it stops shortly after

 Did you restart dbus? (you'll need to log out of X to do this or it will 
 crash 
 you out of it).

I actually meant reboot above where I wrote restart.

And you see all those options listed in firefox-bin buildconfig? Then this
is surely not the Firefox built by upstream (mozilla.com). They would only
use a minimal set of build options not all the rubbish (most of which is
currently ignored or just obsolete) that the Gentoo non-bin ebuilds set.

Yes, it will. cairo-gtk2 is the default (last I looked).

 You need to pick either that one or cairo-qt if you are building on linux.
 
 --enable-oji

 Open JVM Integration:  it enables support for the java plugin named
 libjavaplugin_oji.so

But that will only work until FF 3.5.x. 3.6 has OJI support removed.
And as all up-to-date Java plugins without security problems on Linux
are not OJI, you will want to not set this one.

 --enable-mathml
 I don't really need it right now.
 
 Add ac_add_options --disable-mathml to your .mozconfig file.

Don't bother, or does it matter if you save 15 kB in the binaries? Nothing
will run faster if you disable it.

 --enable-storage
 will Firefox run without this?  The help says...

 'storage' is the mozilla wrapper for SQLite, but configure.in doesn't
 eplain what that means.  I don't see where '--disable-storage' is even
 defined, but you can always try it and see what happens.

This is the default, and I think one cannot disable it any more. SQLite
is an integral part of Firefox by now. The flag above is probably ignored.

 --disable-ogg
 One thing I might consider enabling.  Is there a problem with Firefox's
 ogg support, or any other reason to disable it?
 
 I notice that my own firefox builds do compile the code for ogg support,
 but I have no idea what it does or if it works correctly.

Use --disable-ogg is you don't want HTML5-like Ogg-Theora movies in
webpages.

 Merging gnome-media with the pulseaudio USE flag breaks
 gnome-volume-control most horribly IMO, but OTOH I don't

 I found the gnome 2.26 upgrade guide, which points to the
 pulseaudio documentation.
 
 It seems that pulseaudio has its own mixer control (not
 included in gentoo's pulseaudio package) so maybe it does
 make sense to remove that function from gnome's volume
 control applet.

Looking at the pulseaudio documentation it seems to be a very
well-designed system. But there are so many components to it that I
found it very confusing to configure. In fact, after fiddling around
with it for two days, I gave up on that, removed USE=pulseaudio
again, and rebuilt world.
Now I only have the problem that I cannot start the GNOME Volume
Control applet any more. When I try I get

   Some panel items are no longer available
   One or more panel items (also referred to as applets) are
   no longer available in the GNOME desktop.

   These items will now be removed from your configuration:
• Volume Control
   You will not receive this message again.

so I have to go to the full mixer in the menu instead.

My problem was that I never got any sound out of it, with any
application. And I lost all but one mixer slider. With the alsa-based
backend, my system has the peculiarity that it starts up with Front
and Headphone levels at 100% but muted and Master at 100% (unmuted),
I always have to unmute Front before I want any sound. With
pulseaudio active, all but the Master slider were gone, so I didn't
have any way to influence the levels on the other components. At
least that's what I am thinking might have been going on, but maybe
I'm wrong.

Yes, I used the usual |emerge -vpDNu world| and that did remerge
gnome-media.

 BTW, you can also do nicely without the esd USE flag and esound also,
 but you'll need to revdep-rebuild after because lots of packages will
 break (but they all still work perfectly after the rebuild.)

Interesting, nice tip. I just finished getting rid of it. It was a bit
of a mess because revdep-rebuild didn't discover a -lesd in
libgoffice-0.6.la and hence gnumeric failed to emerge until I finally
removed that by hand. But it's great to have one dependency less. And
sound still seems to work. :-)

Yeah, I am reading the sources daily and have done so for several years
nw. FF 2.x used a different database. One which was far less efficient,
more crash prone, and has been unmaintained for several years before.

 On Linux using SQLite in Firefox actually slimmed down the browser
 code (compared to the version that still used mork), as it uses the
 system version for the database.
 
   Yeah sure, just like ie.exe isn't bloated.  Mind you, the system

I just solved a similar block, also involving PyQt4, by adding

But I am already at qt-*-4.5.2 the upgrade to which is a longer
