[gentoo-user] my xorg-server 1.6 seems a bit unstable - what am I doing wrong?

[gentoo-user] my xorg-server 1.6 seems a bit unstable - what am I doing wrong?

[Denis]

I am running the xorg-server-1.6, to which I just upgraded, and kernel
 2.6.27-gentoo-r8, and I am having an issue with the server crashing
whenever I try to drag the scroll bar within Mathematica - which never
happened to me before with previous xorg-servers, and I use
Mathematica extensively.  So I just wanted to ask some questions to
see if any of the warnings and errors I am seeing in the log may
actually cause X to be unstable...

1.  In the log (see below), Xorg shows an error trying to load dri...
Since I have nvidia and glx and don't have dri, I don't have the dri
drivers, so how can I stop Xorg from trying to load dri/dri2?

2.  I get a warning:

(--) PCI:*(0:1:0:0) 10de:01d1:0000:0000 nVidia Corporation G72
[GeForce 7300 LE] rev 161, Mem @ 0x91000000/16777216,
0x80000000/268435456, 0x90000000/16777216
(WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)
(II) No APM support in BIOS or kernel

Will this make X unstable in any way?

3.  Are the freetype and type1 modules now incorporated into X or phased out?

1.6.3.901
is - lets just say you should either use 1.6.3 or 1.6.4
and what about your driver version?
and why 2.6.27? that kernel is acient!

Sorry  - what was that "why?" referring to?  I think I put those
options in when I was working on anti-aliasing the fonts to make them
look smooth.  That still works.

Well, I used 1.6.3.901-r2 because that's what the portage pulled in
when I did emerge -NDavu world.  Portage tree seems to have options to
use 1.6.4, but it was not pulled in by emerge, so maybe it is masked
or keyworded?

The kernel...  Well, I am guilty of not keeping up on kernel updates
because restarting the machine for each upgrade isn't always an option
with my work.  Do you think this version of the kernel may contribute
to X instability?

i am saying that you should try the latest kernel with the latest driver for 
your card

Re: [gentoo-user] my xorg-server 1.6 seems a bit unstable - what am I doing wrong?

[Denis]

I see.

Well, I am running nvidia-drivers-180.60, and versions 185 and 190 are
masked by ~x86.  Same for the xorg-server-1.6.4.  So the only thing I
could do really is to update the kernel...

But xorg-server-1.5 was perfectly stable for me, so I don't see how
kernel upgrade would be helpful here, given that nvidia-drivers aren't
in the kernel.

nvidia drivers load into the kernel. Driver-kernel interaction can cause a lot 
of problems.

> nvidia drivers load into the kernel. Driver-kernel interaction can cause a lot

Alright, I am now running 2.6.30-gentoo-r6 kernel, but I still have
the same issue.

I think it's a scroll-bar that triggers it.  If I drag a scrollbar
down with my mouse and then run it back up, there is a delayed
response (especially in Acrobat Reader), and when I do that in
Mathematica 5.2, that simply crashes X.

Now I am kind of regretting that I upgraded to xorg-server-1.6...  I
was very happy with 1.5 and before.  Sigh.  May this be a library
issue?  Gtk?  I received some kind of an error from Gtk, if I recall,
while using acroread, but acroread did not crash...

you could rebuilt gtk, I never had crashes or problems with acrobat and I 
don't have mathematica :)

Acroread has always been particularly unstable. I know nothing about the
Linux version of Mathematica.

You can always try revdep-rebuild.

He may also want to ask the question "Do I *really* need acroread?" and get 
the full complete answer. In my experience very few people actually need all 
the features in acroread, and okular|evince are quite adequate

Do okular or eveince have a "print current view" feature? Thats
one thing in acroread that xpdf never had, and I can't live
without it.

I am flexible on acroread, but acroread doesn't crash X - just gets a
little backed up.  I am OK with that.

But X crashing from my use of Mathematica is absolutely unacceptable -
this is what I need for my work.  Before I upgraded to xorg-1.6 and
libxcb-1.4, this *never* happened, not once, *in several years*, under
extensive use, and I have been using the same Mathematica version all
this time, 5.2.  So if downgrading X and libxcb is what I have to do
to restore reliable operation of my machine with Mathematica, then
this is what I am doing next.

Let me ask this next:  is the downgrade of libxcb and xorg-server possible?

I agree, it shouldn't crash.  Are you starting Mathematica by clicking on
an icon in a menu?  If so, I'd suggest starting it from an xterm command
prompt because you may see some helpful error messages before the crash.

I tried that, actually.  There is no warning in the terminal window.
And I have been looking at Xorg error logs also, but there is nothing
useful at the end of them!

All I have is:

(WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)
(EE) Failed to load module "dri" (module does not exist, 0)
(EE) Failed to load module "dri2" (module does not exist, 0)

One curious thing...

(II) Module nvidia: vendor="NVIDIA Corporation"
        compiled for 4.0.2, module version = 1.0.0
        Module class: X.Org Video Driver

Why does it say "compiled for 4.0.2" when all the other X modules say
"compiled for 1.6.3.901", which is the xorg-server version?  I'm sure
that's nothing, but I'm just grabbing at straws here.

I am a Mathematica 7 user on amd64 (gentoo-sources 2.6.30-r5) with an
nvidia graphics card, and I just completed the same X upgrade this
evening. So far Mathematica has not given me any issues.

For what it's worth, I also receive the same "compiled for 4.0.2"
messages in my logs for the nvidia module, though I have not recompiled
my drivers (180.60) since the upgrade. dri and dri2 are not loaded, as
you have above. After glancing through your xorg.conf and X logs, I do
not see any glaring issues that would cause the problems you are
experiencing.

Two suggestions (apologies if they have been suggested already):

1) If you haven't already, recompile your xf86* packages. Somehow I
missed those when upgrading X, which caused issues for me.

2) Mathematica (at least version 7) ships its own version of Qt, which
it will use instead of the system version of Qt. If Mathematica 5 does
something similar -- sorry, I have never used that version on Linux, so
I do not know -- then it's possible that the old libraries are causing
issues. At least in version 7, removing the Mathematica-supplied Qt
libraries will cause Mathematica to use the updated system Qt libraries.
For me, the Qt libraries shipped with Mathematica are under
(install_directory)/SystemFiles/Libraries/Linux-x86-64/. If Mathematica
5 ships libraries that are also installed system-wide, then I would
suggest moving the Mathematica files to another location and seeing if
using the system libraries helps with your crashing issue. For me,
removing the Mathematica Qt libraries made Mathematica faster and look
better.

Good luck with your issue.

Thanks very much for all this information about Mathematica - that
gives me a glimmer of hope!

I did recompile all the xf86 packages that qlist came up with.

This is very illuminating.  I looked in the
"/usr/local/Wolfram/Mathematica/5.2/SystemFiles/Libraries/Linux"
directory, and this is what it contains for me:

libguide.so
libgmp.so.3
libvml.so
libmkl.so
libmkl_def.so
libmkl_lapack32.so
libmkl_lapack64.so
libmkl_p3.so
libmkl_p4.so
libmkl_p4p.so
libmkl_vml_def.so
libmkl_vml_p3.so
libmkl_vml_p4.so
libmkl_vml_p4p.so

Are these names familiar to anyone?  Are these Qt libraries or are
there others too?

This is probably the gmp (GNU Multiple Precision) arithmetic library.

I don't have this one, but I'm pretty sure it is part of Intel MKL (see
below).

These are part of the Intel Math Kernel Library (MKL).

My original Mathematica install had the following Qt libraries, in
addition to a Qt plugins directory:
libQt3Support.so.4  libQtCore.so.4  libQtGui.so.4  libQtNetwork.so.4
libQtSql.so.4  libQtSvg.so.4  libQtXml.so.4

These are all Qt 4 libraries, which did not exist when Mathematica 5
came out. I do not know what toolkit Wolfram used instead, but I was
hoping it would be Qt3, GTK, or some other standard toolkit, as that
would have potentially solved your issue. Are the files you listed all
of the .so files under your Mathematica installation directory? Also,
could you post the output of ldd on your main Mathematica executable?
The main executable for me is
(installdir)/SystemFiles/FrontEnd/Binaries/Linux-x86-64/Mathematica.
This will indicate what libraries Mathematica uses.

Another thing to try is playing with Java. Mathematica also ships its
own bundled version of Java (again, Mathematica 7, I don't know about
version 5). I have never tried to have Mathematica use sun-jdk instead
of the bundled version, but it may be worth a go. As far as I know,
Mathematica only uses Java for J/Link and not for the user interface
(unless using custom interfaces with GUIKit - I've never tried that), so
this probably is not the culprit, but you might try it. I have had
problems with Java and Xlib/XCB in the past, even when there was no GUI.

Another place where you might find more information or issues is
Help->About->System Information->Devices (or similar).

You might also check to see if you have any updates available:
http://www.wolfram.com/products/applications/updates/


If none of the above works, I would suggest reverting the upgraded
packages individually to figure out which package or packages causes the
issue. From there it would be much easier to figure out what is causing
the issue.

If you post the output of the ldd command above, I might be able to find
the source of the issue, or at least narrow down the search for which
package is causing the issue, but other than that there's not much more
I can do. Sorry, I don't have a copy of Mathematica 5 to play with to
see if I can reproduce this; I still used Maple back then, before I made
the switch to Mathematica 6.


Is there a particular function that seems to trigger the crash when
scrolling or does scrolling crash X every time? 


Good luck. I hope any of this helps.

        libdl.so.2 => /lib/libdl.so.2 (0xb7cc9000)

So far, I see a bunch of references Java directories in the
installation and a few .jar files.  I haven't seen any reference to
Qt.  I did see the GUI-Kit and JLink in the AddOns directory.

Basically, the only thing that triggers the crash is if I hold down
the mouse button and drag the scrollbar UP right after I drag it DOWN.
 Dragging it down doesn't seem to make any difference by itself and
hasn't crashed the program until I reverse and drag UP.  Sometimes
going up slowly will be OK too, but if I drag UP rapidly, it will
crash.  I can use the scroll arrows on top and bottom of the
scrollbar, and it will scroll without incident, albeit slowly.

Can the integrity of the above library links be checked, or would
rebuilding all of them again make any difference?  What is the command
to determine which package the given .so.* file belongs to?

Many thanks,
Denis

That sounds really bizarre. I have no idea what would be causing that.

equery (from app-portage/gentoolkit) can tell you which package a
particular file belongs to. `equery belongs /path/to/filename` should do
the trick. You could try downgrading those packages to see if it fixes
your issue. I have not tried downgrading just one or two X libraries,
though I have heard that it can break pretty badly (especially with
respect to libxcb), so I would make a backup first. Another option could
be trying an updated version of X from the x11 overlay. Maybe someone
else on this list has experience with either case and can offer some
pointers; I unfortunately have none.

Packages with the above-listed libraries: x11-libs/libXt,
x11-libs/libXmu x11-libs/libSM, x11-libs/libICE, x11-libs/libX11,
x11-libs/libxcb, x11-libs/libXau.

Good luck; I cannot think of anything else to suggest.

sounds like a segfault

For example, data gets moved around in memory as the display is scrolled and 
somewhere there is a pointer to that memory. It gets updated somehow but when 
the scrolling is rapid the pointer gets used after the data is moved and 
before the pointer is updated.

If it's something along these lines it's a) horrible to find and fix and b) 
horrible code

Re: [gentoo-user] Re: my xorg-server 1.6 seems a bit unstable - what am I doing wrong?

I tried a few things today:

1)  rebuilt all x11-libs, media-libs, and anything I could think of
that would be related to x11-libs (such as gtk+, qt...)

2)  downgraded to xorg-server-1.5

Neither of these things helped.  Alan's hypothesis sounds plausible,
but I don't even know which package to point fingers at!  Probably
it's the Mathematica interface itself, which is horribly old by now,
but I cannot upgrade it at this time.  As I said, dragging the
scrollbar down works fine, but you drag the scroll bar up, and in a
few seconds X gets zapped.  I tried instead clicking above or below
the scroll bar to avoid dragging.  That is a tad better, but after a
few times, it goes down again...

The weird thing is that I never had this problem before doing the
massive lib-xcb upgrade, and obviously the xorg-server doesn't seem to
be helping or hurting anything, so I went back to xorg-server 1.6.

Is there any procedure out there about de-Xifying your system?  I
don't have the time right now to do all this, but I am just wondering
if some people have removed everything X-related from their system and
started anew without completely wrecking the box...

I would take a look at the world file and remove everything X related. 
A --depclean should then remove everything X related.

Keep in mind, that could be a huge amount of stuff to re-install.  I
would make binaries of *some* things that you know would not affect the
programs you are having issues with.  Say for example OOo or some other
large packages that take a while to compile.  You can then use the -k
option to reinstall them.  Naturally, I wouldn't save anything related
to X itself.  I would recompile them from scratch.

I wish I had better ideas or a quick fix.

Have you `emerge -e world` yet?

I have that going now.  I offloaded OpenOffice to shorten the duration
of the rebuild, and I don't have KDE or Gnome - just fluxbox.  So it
should finish by sometime tomorrow, probably.  There are 604 packages
total.  Instead of trying to rebuild X-related stuff in parts, I
should have just done that from the beginning.

Dale - thanks for the advices also.  That's the route I thought about
taking.  Doing 'emerge -e world' first seems like a reasonable thing
to do.  It could be that whatever is causing this cannot be resolved
by a simple rebuild.  Whatever went into the lib-xcb upgrade probably
is either incompatible with the Mathematica frontend or has a bug
that's being exploited in this situation.  Keeping my fingers crossed
for the rebuild for now. :-)

Re: [gentoo-user] Re: my xorg-server 1.6 seems a bit unstable - what am I doing wrong?

[Denis]

Ok, "emerge -e world" completed successfully.

Bad news: X still crashes when scrolling in Mathematica...

On to the downgrade of xcb then, as much as I'd rather not do that.
As suggested, I would edit the world file to remove main X packages
and then use emerge --depclean to prune out the danglers.  As someone
who has never done this before, I got two questions:

1.  The easy one:  where is the world file located these days?

2.  The hard one:  which packages do I remove from the world file to
clean out anything X-related?  I read of a suggestion to remove
"x11-base/xorg-x11" and the rest would follow from depclean...  Is
that too optimistic?

Thanks,
Denis

1:  /var/lib/portage/world 

2:  The file is in alphabetical order nowadays.  The X stuff should be
at the bottom of the file.  Keep in mind tho, if you have a GUI such as
KDE installed, that will pull the X stuff as a dependency. Things like
Seamonkey may even pull in some X stuff.  After all, don't you have to
have a GUI for things like Seamonkey to work?

Not on your list but if you have done a emerge -e world, I'm not real
sure what this will accomplish.  That should have recompiled EVERYTHING
on your system already.  I would be looking for a mailing list for the
software to see if they know about this issue and have a fix or if they
can give some ideas or even commands to run to help them fix it.  I'm
not real sure that this is going to help any at all. 

That help?

At a minum you'll need to remove

X
cairo
firefox
gtk
motif
opengl
pdf
qt3support
qt4
truetype
scb

There will be others, that's just obvious ones from a quick scan through. Also 
remove similarly obvious stuff from package.use

The as Dale said, manually edit your world file to remove everything that is 
obviously X related. But first, verify that "emerge -avuND world" want to 
merge nothing, otherwise --depclean will complain.

Then the fun starts:

emerge -a --depclean   and let it do whatever it wants.
emerge -pvuNDt world   and look closely at what X stuff it wants to pull in. 
See if it's a dependency thing or a USE flag thing, and deal with it. 
Eventually, emerge -pvuND world will not want to remerge anything, only 
rebuild stuff due to changed USE flags.
--depclean again, rinse and repeat as many times as you have to (probably 
lots).

When you have done all this, and it will take a day or three, you will no 
doubt realise that it was not worth the effort and you should have just 
reinstalled without X, or fixed the underlying problem.

Excising X is like downgrading to stable from unstable - not worth the effort.

Sorry, but them's the breaks :-)

Remove the flags from make.conf and also from package.use

And if you run into a snag, try this option with emerge: --with-bdeps y 
I actually have that in make.conf for mine. 

As mentioned by Alan, I really doubt this is going to do much if any
good.  After you did a emerge -e world, that is pretty much it.

Let us know what blows up.  ;-)

Nothing blew up ;-)  I was successful removing X, downgrading, and
getting X working again with xorg-server-1.5.3 and libxcb-1.1

FYI, the working package.mask file for this operation is:

>=x11-libs/libXext-1.0.5
>=x11-libs/libX11-1.2
>=x11-libs/libxcb-1.4
>=x11-base/xorg-server-1.6
>=x11-base/xorg-x11-7.4
>=x11-proto/xproto-7.0.15
>=x11-proto/xextproto-7.0.5
>=x11-libs/xcb-util-0.3.5
>=x11-proto/xcb-proto-1.2

However, this must not have restored my previous X configuration fully
because Mathematica still crashes.  So I've decided to abandon this
attempt, remove all masks, and allow the full X upgrade because I
reinstall all the X packages back onto my system.  While some folks
here probably think this attempt foolish, I still think it was worth a
try, and I learned some new things, which is always good.

I appreciate everyone's help and support with this.

Well, I do foolish things sometimes myself.  Once every few months for
example, I run a emerge -ev world.  Then I reboot and make my back ups. 
At least I know it is a sane build and it will boot if restored from.  I
don't back up as much as I used to since I got DSL.  I guess we all try
something just to satisfy our curiosity if nothing else. 

I do wish it would have fixed your problem tho.  I would travel upstream
and see if you can help them by providing information on the crash.

OK, first off.  I have no clue what this program does.  I'm shooting in
the dark here.  I found this:

http://forums.wolfram.com/mathgroup/archive/2001/Dec/msg00034.html

It seems you are not alone.  I browsed though a couple other places and
saw people mentioning python a bit.  Does this software use python by
any chance? 

I also noticed a lot of talking about I/O issues.  Are you sure and for
certain that you have the right chip set compiled for your hard drive? 
I ran into a lot of errors once and I had the wrong chip set selected in
my kernel and although it was trying to work, it didn't work very well
when there was a lot of I/O activity.  Programs would crash and in the
Konsole I would get all sorts of errors including the plan old seg fault
type. 

Again, read the first three sentences.  Just thinking and typing and
that is dangerous for me.  ;-)

I don't think this attempt foolish - but I guess you're getting  
desperate.

Having performed `emerge -e world` I would come to the conclusion that  
the problem is simply Mathematica, with some current libraries. I  
would probably want to try a fresh install of Gnetoo - on a different  
box or hard-drive - to prove the point. But I think I would be  
concluding shortly that it's an upstream bug.

Re: [gentoo-user] Re: my xorg-server 1.6 seems a bit unstable - what am I doing wrong?

[Denis]

Ordinarily, I would also point to I/O errors, but not this time.  I
have had this same version of Mathematica, 5.2, for *years*, on this
same machine, over several kernels and several Xorg upgrades, and it
was rock-solid.  Not one X hang or crash.  Ever.  No error messages or
I/O warnings ever.  The only thing I'd ever see in the console would
be GTK+ errors from other programs.  Something about this latest X
upgrade is making Mathematica unhappy, either because some previously
supported format that worked fine with it has been altered or
something else in that general regard.  This version being so outdated
- that isn't a surprise.  It may not be a bug, so much as an
incompatibility, perhaps

I think the only thing I can do at this point that probably will fix
this is to go to stable arch, but I am not willing to do that because
I like my box the way it is now :-)  It's great and efficient for all
other things.  Before I can get a local Mathematica upgrade, I will
have to resort to using it via X forwarding off the central server.

I forgot to mention this earlier.  The way I found out it was a I/O
error for me was this command.  hdparm -Tt /dev/hda && hdparm -Tt
/dev/hda .  I kept repeating that until it starting giving me errors. 
For mine it was after the third pass.  Something to keep in mind, it
could be something wrong with the driver in the kernel you are using. 
It could be any number of things like this.  It could be that it is a
mismatch as you mentioned between Mathematica and some other support
program such as gtk, python or any other number of things.

Me, I would hop on a mailing list for that software and ask them what
strace command you can run and then send them the results.  It may be
that they can make some sense of the error and recommend a fix or even a
downgrade of some other package. 

You may also want to use the q command to see what was upgraded since it
last worked.  That might point to something too.  I think it is the q
command that does that.

I have downgraded xorg-server before and it is not to bad.  Just mask
the current version and do a emerge -uvDNa world.  You may have to mask
a couple more packages but the error will tell you which ones they are. 
I was able to just mask the one tho. 

If you are using hal, you may have to reemerge the mouse and keyboard
drivers.  I find them using this:  equery list xf86-input  That should
list the drivers that need to be reemerged.  I have three.

I've been having some issues myself (mythtv manages to mess up my screen 
royally, I need to switch to a text virtual console and back to X to 
make the screen legible after viewing a TV-recording in myth). I just 
noticed that the version of the headers for xcb do not match the version 
on libxcb itself. Could this be the cause of my (and Daves) problems? I 
have libxcb 1.4, but headers version 1.5, no 1.4 available for the 
headers. (running a new sync of my portage tree now, just in case I've 
missed something)
