[Ubuntu-x-swat] [Bug 1510998] Re: Xorg crashes with segfault on 15.10

2016-07-02 Thread Johan Tol
Shortly after its introduction I migrated to Ubuntu 16.04. Today I
rolled back the "uxa"-workaround by deleting the 20-intel.conf file from
/etc/X11/xorg.conf.d (I didn't have one before the workaround). After a
couple of hours I still haven't had a single crash. I guess 16.06 solved
the problem.

Dirk Seidel, to see if this is already resolved, could you please test
http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

** Description changed:

  I updated my system from 15.04 to 15.10 yesterday. Since then the X
  server has already crashed 5 times, which renders the system close to
  unusable for me.

The workaround is to disable sna.

Create the file
/etc/X11/xorg.conf.d/20-intel.conf

with the following content:

Section "Device"
 Identifier "Card0"
 Driver "Intel"
 Option "AccelMethod" "uxa"
EndSection

I added the workaround referenced in the other bug, and will see how that goes. 
 It does slow things down, although now I have also disabled compositing in

[Ubuntu-x-swat] [Bug 1510998] Re: Xorg crashes with segfault on 15.10

2015-11-02 Thread Dirk Seidel
Why is the importance changed from Critical to High? I am experiencing
3-5 crashes per day and am not aware of any workaround. This is more or
less an unusable system and I am seriously thinking of downgrading
again.

Johan Tol, have you tried to get a backtrace like I mentioned in #8?
That way it works without problems.

Thought this was duplicate of https://bugs.launchpad.net/ubuntu/+source
/xserver-xorg-video-intel/+bug/1510970, but  the stack trace is slightly
different (See Johan Tol's stack trace above which is exactly what is
seen in 1510970)

I'm not sure what you mean with "kernel call trace".
The first entry in syslog which is related to the crash mentioned in #13  is

Nov  1 12:53:06 gondor org.a11y.atspi.Registry[4315]: XIO:  fatal IO error 11 
(Resource temporarily unavailable) on X server
 ":0"

But this is not always the same. See attached syslog file (#2) for the three 
events at

2015-11-01 Thread Dirk Seidel
I already had two crashes today, but no specific xorg file. One of the crashes 
happened at 12:53:06 according to syslog. Only one file in /var/crash, namely  
_usr_bin_akonadi_maildispatcher_agent.1000.crash is related to that crash and 
occurred at 12:53:08 according to the crash file.
Unfortunately I am not really able to reproduce any crashes. It seems more 
likely to happen when I watch videos (flash or vlc), but is not restricted to 
those circumstances.

Sorry, now I know what you mean: log messages from #3.
These appear at completely different times, so probably they are unrelated to 
the crashes (see again syslog in #2). I mentioned them because they also 
involve the intel graphics, so who knows...

2015-10-30 Thread Dirk Seidel
I tried to get a backtrace according to "Already running programs" for X from
https://wiki.ubuntu.com/Backtrace

I started gdb on the first virtual console (Ctrl+Alt+F1). After
executing "continue" in gdb, I can still switch between the different
consoles, but after typing Ctrl+Alt+F7 to get back to the  X session,
the system is completely frozen (the virtual console is still visible).

Am I doing something wrong?

[Ubuntu-x-swat] [Bug 1510998] Re: Xorg crashes with segfault on 15.10

2015-10-28 Thread Dirk Seidel
** Attachment added: "syslog"
   
https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1510998/+attachment/4507632/+files/syslog

** Description changed:

  I updated my system from 15.04 to 15.10 yesterday. Since then the X
  server has already crashed 5 times, which renders the system close to
  unusable for me.
  
  The corresponding messages in Xorg.0.log.old are:
