Re: [Bug 741930] Re: [natty] nvidia binary packages for older cards - dependencies not met

2011-05-10 Thread Pawel Jasnos
I'd say a simpler but still useful thing would be to make sure that if
some hardware isn't compatible at the time of release because a
proprietary driver is required (and that's the situation here - Unity
doesn't work on Nouveau), then a big, red note of that should be made
in the release notes prompt encouraging for upgrade, so that people
can wait until Nvidia or any other vendor provides updated driver.

Alternatively, the upgrading script should warn user about such
incompatibilities at the start of the process, allowing them to easily
cancel.

 something like:
 xserver-xorg-core  (new version, for the driver compatible)
 xserver-xorg-core-1.9 (legacy, for the driver that not support new xorg)

 then the nvidia-96 package require the legacy xorg instead of the new
 one

2011-05-02 Thread Pawel Jasnos
Timo - would it not be possible to put this driver in universe, as a service 
for users who still have this chip?
I think it will become less relevant with time as I've not seen any newer 
laptops/netbooks having using SiS 671, so it might just happen that when it is 
finally merged with the FD.o, next to no-one might acutally need it.

Some short but intensive testing seems to indicate that, for me, Natty
kernel doesn't have this problem, which is good news.

It seems (but I didn't have a chance to test yet) that the fix might be
this patch from upstream:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.38.y.git;a=commit;h=88f5acf88ae6a9778f6d25d0d5d7ec2d57764a97

I'll test this kernel more and perhaps try to apply this patch to
Maverick kernel and see if it solves the problem as I suspect.

If there's any critical patch added to the kernel, you would need to
rebuild it yourself to get it (rembering to revert the commit) until a
patch for this bug is officially incorporated into Ubuntu kernel.

Yann, first of all can you test your RAM for defects?
Hold left shift key while powering on your computer to see GRUB boot menu and 
select memory test from there. You should run it for a few hours (probably best 
overnight) and see if there are any errors reported at the bottom of the screen 
(in which case you would need to replace your RAM as it is damaged).
 I'm asking you to do this as you said you experienced freezes even on 
2.6.35-22.

Also, looking at ProcCpuinfo.txt which you attached to this bug report,
your processor is indeed single core.

2011-03-21 Thread Pawel Jasnos
May I just add - as mentioned in one of my posts above, the commit just 
preceding the one I bisected this bug to may be related, as on the system where 
this bug occurs there are some very short (quarter to half a second?) freezes 
in cases when this bug occurs, instead of a hard freeze, which disappear when 
that commit is removed. Both of those commits modify page allocator (I can find 
that commit's sha-1 if needed, but it directly precedes this one). I can also 
report another bug for it if needed, but it may be wiser to simply have a look 
at both of the commits.
I don't have any experience in kernel development so I may of course be 
mistaken as to the role of preceding commit.

Also, my way of reproducing this bug, which seemed to work every time:
1. On an affected system, run Open Office, GIMP, Inkscape or any other 
memory-hogging application.
2. Use scp to copy a large file over the local network (I used a 2 Gb DVD 
image).

you don't need to install linux-

If you DO want to install the headers, start terminal and go to the
folder where your sources sit  (if you followed my tutorial exactly:

cd kernel-custom

Kernel compilation produces a lot of warnings and it's ok, as long as it
gives you a 'final product' in the form of .deb packages. Errors (as
opposed to warnings) will stop the compilation and not produce a .deb
package.

To remove packages installed via build dep, you can use this helpful tip:

2011-03-07 Thread Pawel Jasnos
Looks like  the effects of apt being interrupted while it was doing
something before.  It shouldn't matter for kernel compilation, but you
may want to uninstall and reinstall VirtualBox at some point (which
should fix the error). You do need the build-dep linux though, so if the
error occured before the installation finished, then there's a  (very
small) chance that you can get some really weird errors when you attempt
to compile the kernel if you don't fix it.

The first two warnings from update-rc.d don't really mean anything bad,
it apparently is a configuration bug in Ubuntu (
https://bugs.launchpad.net/ubuntu/+source/kexec-tools/+bug/569980 ) -
kdump is used to create kernel crashdumps and all this is saying is that
they will only be created during 'normal operation' (runlevel 2) rather
than also during startup, shutdown, etc (which have different
runlevels).

Oh, and VirtualBox won't be enabled in kernel that you compile - you
would need to create and install kernel headers for your git source for
that; you can do this by running:

fakeroot debian/rules binary-indep

after building the kernel, which would give you linux-headers(...)
package which you need to install so DKMS is able to auto-compile
VirtualBox kernel module.

mm: page allocator: calculate a better estimate of NR_FREE_PAGES when 
memory is low and kswapd is awake

commit aa45484031ddee09b06350ab8528bfe5b2c76d1c upstream.

Ordinarily watermark checks are based on the vmstat NR_FREE_PAGES as it is
cheaper than scanning a number of lists.  To avoid synchronization
overhead, counter deltas are maintained on a per-cpu basis and drained
both periodically and when the delta is above a threshold.  On large CPU
systems, the difference between the estimated and real value of
NR_FREE_PAGES can be very high.  If NR_FREE_PAGES is much higher than
number of real free page in buddy, the VM can allocate pages below min
watermark, at worst reducing the real number of pages to zero.  Even if
the OOM killer kills some victim for freeing memory, it may not free
memory if the exit path requires a new page resulting in livelock.

This patch introduces a zone_page_state_snapshot() function (courtesy of
Christoph) that takes a slightly more accurate view of an arbitrary vmstat
counter.  It is used to read NR_FREE_PAGES while kswapd is awake to avoid
the watermark being accidentally broken.  The estimate is not perfect and
may result in cache line bounces but is expected to be lighter than the
IPI calls necessary to continually drain the per-cpu counters while kswapd
is awake.

It *MIGHT* be also connected to the previous commit  
(7dd373d47c6e0dc124924348265be61990ba0fb6) as I observed some short (0.5 
second) freezes while testing it, but no errors.

I'll see if I can revert it in HEAD and whether it helps - will post
soon.

[Bug 719446] Re: systematic freezes on any kernel version post 2.6.35-22

2011-03-05 Thread Pawel Jasnos
Also, it seems that the main factor in replicability of this bug is a
single-core processor running a SMP kernel (which is stock in Ubuntu) -
any chance someone more knowledgeable in kernel development can have a
look at this ?

N.B. Alan, yes, I could have started with 2.6.35-23 - this would have
saved me ~1 compilation and reboot, probably.

Dave - if Alan verifies this with the HEAD of maverick kernel repository
with this patch reverted, would that be a good-enough proof, or should
he verify it with the HEAD of mainline kernel with this patch reverted?

[Bug 719446] Re: systematic freezes on any kernel version post 2.6.35-22

2011-03-05 Thread Pawel Jasnos
Alan - Are you able and willing to build your own kernel? Risks are more
or less the same as for installing a development kernel, but it takes a
bit of time to compile. If you don't want to build a kernel, but are
willing to trust me enough to test one I built, I'll post  a generic
build here later.

If you can't reproduce the bug with the kernel made with these steps, it
means we suffer from the same thing.

Maverick git repository:

If so, can you please follow the instructions here for installing the tools:  
https://help.ubuntu.com/community/Kernel/Compile#Tools you'll need
(steps are the same as for Lucid).

then, in the terminal, make a directory and download repository from git 
(warning: it's few hundred megabytes), e.g.
mkdir kernel-custom
cd kernel-custom
git clone git://kernel.ubuntu.com/ubuntu/ubuntu-maverick.git
cd ubuntu-maverick
git checkout -b bug-testing master
git revert 58e15f5029c75b45adbcb25cd76a36d26a6c4297
press ctrl+x
fakeroot debian/rules clean
AUTOBUILD=1 NOEXTRAS=1 fakeroot debian/rules binary-generic

This should build for you two .deb packages for linux-image (which you
need to install) and linux-headers (which isn't necessary for this
testing) with version number of 2.6.35-28.49 and place them in your
kernel-custom directory. After installation, you need to reboot and
select the new kernel. You can uninstall it in a standard way (synaptic,
dpkg - choose your favourite) after you've done testing.

2008-06-25 Thread Pawel Jasnos
hmmm... Stupid question - you are running it from GUI, not console??

You may also try to run dexconf first, just to reset xorg.conf to
whatever it thinks is default and then try again. (it looks like
displayconfig-gtk couldn't get screen size - I'd report this as a
separate bug. It's still a package in Hardy (and works fine for me), so
it can be reported :-).

[Bug 65664] Re: Cannot subscribe to exchange shared folders / calender in edgy

2008-04-29 Thread Pawel Jasnos
hmmm, what I did now is just setting the machine domain (there is an
option in the administration menu in Ubuntu to do this) to be the same
as the full domain name of windows - and now I have removed the
/etc/hosts entries and for me it's still working.

lilbudda - I never tried using Evo with external access exchange, but I
think it wouldn't work (as it tries to talk to the domain controller to
get GAL) -- I need to check it in evolution sources to verify that, but
if that's the case, then it is imho a different bug than this.

weierj - try to use nslookup on windows to see what domain windows
*thinks* exchange is in (e.g. nslookup exchangefrontend) and use it as
your ubuntu domain (I rarely see windows domains that use domain.org
domain - more often It's domain.local). or try running ipconfig /all and
see what is the domain name that windows uses.

Hope this helps

Am I wrong in thinking that dexconf should generate xorg.conf which
would use vesa and 800x600 resolution, which should always work, and be
a good starting point?

2008-02-15 Thread Pawel Jasnos
Hi,

I observe exactly the same symptoms - when I try subscribing to another
person folder, I cannot access it because of generic error. I have
full mailbox rights to that other mailbox, so I don't have problems
accessing it as http://exchange_server/exchange/other-mailbox using my
own login credentials. I would be very happy to provide more info on
this, only if you point me to what you may need :-)

[Bug 65664] Re: Cannot subscribe to exchange shared folders / calender in edgy

2008-02-15 Thread Pawel Jasnos
Ok, I found a solution - this may be silly, but works. I have added ip 
addresses and host names of:
- exchange OWA server
- primary DC
- secondary DC
(last two for compatibility with GAL).

to /etc/hosts . I've done two entries for each of them ( one with the
sole host name, the other one as a fully qualified windows domain name,
eg. hostname.domainname.local ) and now it works flawlessly. I think
this proves that this is not bug in Exchange handling, but rather dns
server requests. I've started using hostname in stead of ipaddress for
OWA server. After all this, it miraculously started to work :-).
