I'm having doubts that systemd is involved in this issue. Installing
sysvinit-core and purging systemd results in similar behaviour when
X is started on tty1. There is no hanging this time but returning to
a tty after logging out of one doesn't occur most of the time. When
it does happen it is almost as though pressing keys at random is the
trigger. A bug in xinit?

 Yes, this works as expected. I then logged in on tty1 and started X.
 Then I logged in and out of tty2 four times and the computer behaved
 differently each time. On the first logout from tty2 I saw X on tty1
 flashing by before ending up on the tty2 login prompt. On the second
 logout from tty2 I ended up in X on tty1 (but with no freeze). The
 third logout was like the first with X flashing by. On the fourth
 logout I ended up in X on tty1 again but now the computer hanged
 completely.

Well, well, so it does. Not quite with the same sequence but logging
out from any terminal puts you back to X on tty1 and I can get a freeze
by trying to switch back to a terminal. None of this happens for me if
X is started on any terminal other than tty1.

Systemd handles the terminals so this very much looks like a bug in
that package. Do you intend to report it? I don't see what is special
about tty1.

$SHLVL appears to be one of the players. Change

  if [ $SHLVL = 1 ]; then

in ~/.bash_logout to

  if [ $SHLVL = 2 ]; then

and see how you go on.

I get similar results if I instead run X in in tty2 and log in and out 
on tty1 - the X session flashes by or I end up in X and sometimes the 
computer hangs.

Could it be related to the graphics driver? What card/driver do you use? 
I remember having issues with switching between ttys when using the 
NVIDIA driver in Debian Wheezy:

The exit command is a bash builtin command. It causes bash to exit, as
does CTRL-D. When bash exits a getty is respawned with a new login
prompt on the terminal. You do not see this new login prompt because you
have been switched to X - but it is there; have a look at 'ps ax'. On my
machine I can get to it (X is on tty1) by pressing CTRL+ALT+F1 (I stay
in X at this point) and then CTRL+ALT+Fn (I am now on ttyn).

The graphics driver route doesn't feel right as an explanation. I do not
know what the explanation is in any detail but here is something to do
which is constructive and instructive:

  mv ~/.bash_logout ~/.bash_logout-orig

and exit. Where are you now? X or a terminal?

The ~/.bash_logout files on this machine and my working unstable machine
are identical. clear_console(1) on both tells me the same thing.

  clear_console -q

on the unstable machine always leaves me at a terminal; on this machine
the command almost always puts me into X.

You appear to have two things you regard as issues:

1. Logging out of tty2 in some way you do not specify puts you back on
   tty1 with X. How do you leave tty2?

2. X is misbehaving.

The only way I can think of that you can have X on tty1 is by using
startx. Is startx the way you start X?

The second thing is whether this 8.1 Debian is an upgrade or a new

 about diagnosing this problem, but it seems that the kernel (3.13) is
 not terribly happy with this video card in general.

After fiddling with an... ahem... particular Debian-based distribution's
live CD, I was able to figure out what the problem was.  When booting
this CD, the system would appear to boot normally, but when I would
expect to be dumped into a desktop environment, both monitors turned off
instead... what I would expect to see if the desktop were being
displayed on some other monitor...

Long story short, my motherboard's onboard Intel GPU was enabled in
addition to the PCI-e nVIDIA GPU.  Disabling the onboard GPU has
resolved all of the problems I was experiencing.

In fact, it's entirely possible that the onboard display was being
activated.  I didn't think of this because in Debian the attached
monitors would still display whatever they last were displaying.
Perhaps the system just wasn't completely deactivating the nVIDIA GPU,
and so they displayed whatever they were, forever.  I may turn the
onboard GPU back on and attach a monitor to it to satisfy my curiosity.

System freeze during boot with nvidia GPU on jessie

2014-03-23 Thread Christopher David Howie


Hello,

I am not subscribed to this list so please CC me on replies (and quote 
this line so others know to as well).


Also I was not sure if jessie issues belong here or on the 
debian-testing list, but the latter doesn't have very much activity at 
all and appears to be geared more towards install/upgrade issues.  If 
debian-user is the wrong list I have no problem going there.


I have an Nvidia GeForce GTX 760 card, and I've been unable to get this 
card working correctly in jessie, including even booting the system 
after installing.


The system hangs at Waiting for /dev to be fully populated unless I 
specify the nomodeset kernel parameter.  Blacklisting nouveau does not 
keep the system from freezing without nomodeset.  Modprobing nouveau or

Any suggestions would be much appreciated.  If there is other 
information I can gather let me know.

Hi Joey,
Sorry for the late answer. I've been on parental leave for a week and is

We've never gotten any kernel panic errors, if I recall correctly. We only
had the strange pause-error where the entire machine stopped for a few
seconds and then continued as if nothing had happened.

The x3650's (both M1 and M3) that we have are used with Debian etch,
etch-n-half, lenny and squeeze without any special drivers or kernels. Apart
from the clock sync issue (which we had on almost all machines for a while)
and the pause-error (which we only had on one machine, luckily) we've
never had any problems with the servers.

Could it be a hardware error on your machine? I don't know if the server is
in production, but if not, does the same problems show up after a reinstall
or if you install another OS (Windows, FreeBSD?).
I hope that you find the cause of the problem!

Best regards, Jonas Mixter

Hi Jonas -
I am using the x3650 with the ServRaid 8k card.
I am getting kernel panic errors - have you seen these type of messeges?
I have downloaded the lasted firmware for the controller, bios, and
drives - but I am still getting weird system issues.
I sometimes have the system very unresponsive to me - or when the
server screen goes to sleep - it never comes back.
I had a couple of kernel errors show up on the screen - but do not
know what they mean or how to fix them - i have googled.
Where does debian store hardware issues or messeges ?
Have you installed a special driver or kernel on your system for it to
be stable ?
The last thing I did in the IBM bios is turn off virtualization - that
makes the system a little more responsive but still have wierd kernel
errors.

Hi!
I have an IBM x3650 server with a single quad-core 2.0 GHz Intel Xeon
(and one empty CPU-slot) and 4 GB RAM. The system is running an ordinary
installation of etch.

I used the linux-image-2.6.18-6-686-bigmem kernel but had some strange
problems with the server. It all booted fine but occasionally the entire
system freezed for a few seconds. Both running services (smtp, pop,
imap-daemons, ongoing ssh-sessions) and the local console is dead.
After a little while (about 10-20 seconds typically) all the services
became avaliable again. This has happened at least 5-6 times during last
afternoon and evening.

I booted the server with noapic, nolapic and clock=pit as kernel options
(I later saw that clock was replaced with clocksource, so I don't know
if that option changes anything) during the problems. The kernel hangs
from time to time at boot without the noapic and nolapic options, and
there also seems to be problem with clock skew on the machine.

Now I've upgraded the kernel to etchnhalf
(linux-image-2.6.24-etchnhalf.1-686-bigmem) and I hope that this will
solve the problem. I have seen a few signs of the freeze after the
upgrade, but I cannot verify it yet.
The previous booting problems without noapic and nolapic seems to be
gone with this kernel version, so the kernel now boots without any
special options. I have had a few problems with the clock too after the
upgrade... The kernel prints this at boot time:
kernel: Time: tsc clocksource has been installed.

So, finally, my question... :-)
Is there anyone else running etch on a IBM x3650 (dual or quad core, I
have clock skew-problems with another server too that has a dual core
Xeon)? Is there any kernel parameters needed? Which kernel version is
recommended? 2.6.18, 2.6.24 or a custom kernel?
Does anyone else (with a x3650 or not) have similar problems with etch
and x3650? I get no errors in dmesg or syslog about the freeze and the
system just run on as nothing has happened afterwards.

Best regards, Jonas Mixter

Hi,
I got exactly the same Problem.
Using Debian wheezy (fresh install in Dec. 2012, so no update from 
squeeze/gnome2.x with a radeon hd 5850 Card with one Monitor.

Disable KMS = only fallback Modus , so no realy solution.
Any other Idea?

Hi,

After some time and always after clicking on an icon or something else
on the screen my system lock up. It completely freezes, nothing works:
no alt+F1 , ctrl+alt+del, alt-backspace, and no remote login via ssh.
The only way to reboot is using the power button (off and than on).
Using the reset button results in not finding the boot disk anymore. I
can't find anything in any log file (messages, kernel, debug, daemon)

Does anyone recognises this behaviour, i.e. is it a feature? What could
I try to diagnose the problem? Anyone any idea as to find the cause, so
I can file a bug against a package that could be the problem?

I can't help, but I will say I saw that a couple years ago.
Testing/unstable with Radeon, I believe it was, with either Awesome WM
or Fluxbox. I never got very far in diagnosing it, but from what I did do, it
seemed like it was an issue in Xorg (core or driver, I am not sure). If it
is like my situation, using something besides gnome 3 will not help.

At some point the problem downgraded to just locking screen and input,
it would be accessible via ssh or similar. And then after some more
updates, it went away.

With the Intel system I use now, I have had a few times of instability
with crashing or freezing X, but never complete kernel lock, and it
was not as frequent and did not last as long... not sure how
related they might be.

Cheers,
Kelly Clowers

Before upgrade to Gnome3 and radeon opensource driver...

what driver you had installed?
which graphics card is installed (radeon model)?
how many monitors are installed?


does de following commands:

* disable GDM to no start -- update-rc.d -f gdm3 disable
* start a computer and login in console with a normal user

the radeon driver uses KMS, notes from driver:

* Starting with this version, the radeon driver enables kernel mode setting

native resolution on the console. KMS also allows faster VT switching
and mode changes.

Enabling KMS may break X.org drivers that are not KMS-ready, for instance
radeonhd or vesa.

In case of trouble KMS can be disabled with the 'nomodeset' kernel
command line parameter, or by editing /etc/modprobe.d/radeon-kms.conf.

System freeze / IBM x3650 kernel options

I've had that happen myself for the last couple of kernel upgrades on my 
laptop, but not very often. Just turn off at the wall switch, slip out 
battery if it's being used, and turn on and boot again and all's well for 
another series of boots. Since the last kernel upgrade this happens less but 
still does occur.

I assume that it will rectify itself as the upgrades progress.

Load web page with Flash movie -- System freeze?

This is deeply weird and should be impossible.

On an HP DV6100 laptop running a freshly-updated Lenny, I use Iceweasel 3
and the Flash library from Adobe, also updated today.

I reinstalled Lenny last week.  Starting Friday (I didn't use the laptop
over the weekend) and continuing today (Monday), if I open any web page with
a Flash movie on it, the computer freezes.  I don't mean that X freezes, I
mean the entire system.

As a test, I ctrl-alt-F1'ed to a VT and ran sleep 3m; killall xdm.  I've
tested that invocation, and it does in fact kill X when the sleep expires. 
Then in an xterm I ran script iceweaselfreeze.txt ; iceweasel .

Iceweasel loaded.  I navigated to YouTube and tried to play a Captain
Disillusion video.  The first frame loaded, and then everything froze.  The
command in the VT failed to kill X, and I was forced to power-down to reset. 
The file iceweaselfreeze.txt is empty.

I can see a badly-behaved Flash plugin killing Firefox/Iceweasel.  I can
even see it freezing X.  How can it freeze the script running in the VT?
It's a really solid freeze--not only do ctrl-alt-f1 and ctrl-backspace stop
working, so do Caps Lock and Scroll Lock and the rest.

A test with konqueror freezes the entire system BEFORE the first frame of
the Flash movie displays.

The system remains stable indefinitely in Windows Vista, so if it's a
hardware problem it's a subtle one.  I haven't done extensive tests, but it
seems to work far more stably in Knoppix, too.

Nothing suspicious in syslog, not surprising considering how sudden and
total the freeze is.

Kernel issue?  2.6.24-1, FWIW.  Xorg issue?  

Any debugging suggestions?  Install another distro as a test?  Is there an
easily-accessible debug kernel or debug version of xorg?  I'm a very
experienced Linux user and former sysadmin, but not a systems programmer.

As a test, I ctrl-alt-F1'ed to a VT and ran sleep 3m; killall xdm.  I've
tested that invocation, and it does in fact kill X when the sleep expires. 
Then in an xterm I ran script iceweaselfreeze.txt ; iceweasel .


Iceweasel loaded.  I navigated to YouTube and tried to play a Captain
Disillusion video.  The first frame loaded, and then everything froze.  The
command in the VT failed to kill X, and I was forced to power-down to reset. 
The file iceweaselfreeze.txt is empty.


I can see a badly-behaved Flash plugin killing Firefox/Iceweasel.  I can
even see it freezing X.  How can it freeze the script running in the VT?
It's a really solid freeze--not only do ctrl-alt-f1 and ctrl-backspace stop
working, so do Caps Lock and Scroll Lock and the rest.

A test with konqueror freezes the entire system BEFORE the first frame of
the Flash movie displays.

The system remains stable indefinitely in Windows Vista, so if it's a
hardware problem it's a subtle one.  I haven't done extensive tests, but it
seems to work far more stably in Knoppix, too.

Nothing suspicious in syslog, not surprising considering how sudden and
total the freeze is.

Kernel issue?  2.6.24-1, FWIW.  Xorg issue?  


Any debugging suggestions?  Install another distro as a test?  Is there an
easily-accessible debug kernel or debug version of xorg?  I'm a very
experienced Linux user and former sysadmin, but not a systems programmer.


Works for me...

It's not just that, though.  Any Flash movie will solidly lock it.  For
instance, Pandora loads, then the laptop stops.

Iceweasel plus swfdec on an amd64 works like a charm here 
too...(testing/unstable)...youtube and all that.

It seems to me you can only try a different Lenny or distribution.
Those people that said WFM you don't know what kernel they are running.
You mentioned Knoppix: are you able to play a Flash movie on that?

In my testing earlier this year, swfdec won't run multiple instances, which
is a thing I like to do.

Like someone said in another thread, I was hoping to help.  Nobody has ideas
on how to actually find the cause of the problem?

I'll test Knoppix when I get home tonight.  I'm sure it doesn't come with
the non-free Flash plugin, of course.

Hi Carl,



 It's not just that, though.  Any Flash movie will solidly lock it.  For
 instance, Pandora loads, then the laptop stops.

  I don't know if my experience will help, but when the 'flashplugin-nonfree'
package was updated to the 1.7.* series, I started experiencing freezes for
about 30 seconds at a time just using my ISP's webmail interface.  I ended
up holding version 1.6.3 up until a couple of days ago, when I investigated
more carefully and found that 1.7.* switched to using the Debian alternatives
system -- to allow sysadmins to select the particular library which will
provide support for Flash.  See bug report 497385:

http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=128;bug=497385

  Following the instructions there, I updated to flashplugin-nonfree 1.7.2
using 'aptitude', tested that I still had the problem with freezing (I did),
closed Iceweasel, ran the suggested command line incantation in the bug report,

update-alternatives --auto flash-mozilla.so

then ran Iceweasel again.  The result was that 1.7.2 now works as good for me
as 1.6.3 ever did.

  I'm not sure this will solve your problem, but I'm hoping it helps you (or
anyone else reading this).


HTH,
Dave W.

2008-10-13 Thread Daniel Burrows

On Mon, Oct 13, 2008 at 11:50:02AM -0400, Carl Fink [EMAIL PROTECTED] was 
heard to say:

 It's a really solid freeze--not only do ctrl-alt-f1 and ctrl-backspace stop
 working, so do Caps Lock and Scroll Lock and the rest.

  It sounds to me like the kernel is locking up or the hardware is
being wedged somehow (by which I mean a privileged driver is putting it
into a bad state).  It doesn't happen as often as it used to, but this
is usually a sign of a bad driver somewhere: since you're playing a
video, likely either your video or your sound driver, but your network
driver is an outside possibility since you're using Youtube.  And of
course it could be an interaction between two of those...but I would
suspect the video driver, just because those have a history of
flakiness.  What video card do you have and what driver are you using?
Do you have DRI and/or Xv enabled, and can you disable them?

  Do programs like mplayer / totem work?  Even if you enable all the
bells and whistles? (Xv, etc)  What about video games that use DRI or
other forms of acceleration?  e.g., something like Neverball.

  Is there any way to download the video and play it offline (to
eliminate the network variable)?  I don't know flash well, but
selectively disabling video and audio would help too if it's
possible.

 A test with konqueror freezes the entire system BEFORE the first frame of
 the Flash movie displays.

  I'd guess then that it's probably not the network.

 The system remains stable indefinitely in Windows Vista, so if it's a
 hardware problem it's a subtle one.  I haven't done extensive tests, but it
 seems to work far more stably in Knoppix, too.

  If you have the wherewithal and a spare system, you could try sending
syslog messages to another computer, but I doubt you'd get much out of
it.

HTH,
  Daniel

This sounded really promising.  I was going to try it.

But now the stupid computer won't boot past setting the system clock in
Linux.  Still works fine in Windows.

Time to reinstall again, I suppose.  This is becoming stupid.
