compiz.real crashed with SIGSEGV

I have been able to solve the problem, thanks to an Ubuntu forum post. However, it might still be a bug, since not everyone will find the solution.

The problem was that the ATI flgrx driver failed to load with kernel -16, as of the time I originally posted this bug.

But flgrx still worked in kernel -15. Using kernel -15, hardware manager, I disabled the ATI restricted driver. Using synaptic, I obtained the envyng package and its GUI. From terminal, I used sudo envyng to download and install a new ATI graphics driver. Then I re-booted to kernel 16. At first, it was in the wrong resolution. But I enabled the new ATI graphics driver and re-booted again. All was well.

Someone suggested that afterwards, it helps to re-install compiz. I don't know.

Hello,

I can confirm this bug with an NVidia 6800Go graphics card on Ubuntu Hardy Heron beta i386. Crash in compiz.real after a first unsuccessful login (white screen). I then killed X with CTRL+ALT+BACKSPACE, and logged in normally before getting this message.

Hello

I do not have the detailed information handy that you have but the crash I
had was also with compiz-real. It followed the update of the compiz programs
on my Hardy Heron beta i386 system. I am using the Linux 2.6.24-16-generic
i686 kernel with Intel 915 graphics system on my motherboard. I was able to
get a usable desktop using Gnome-failsafe. I tried a few measures that did
not work, however when I did a complete reinstall of all the compiz packages
I was using my system was up and running properly again. It is now several
days and everything is running fine.

Thanks, I am an almost total Linux novice. I am running an ATI video card
and gather from your notes below that the crash is somehow related to
video. I have no idea what the compiz programs are or how to reinstall
them. I do find Ubuntu 8.04 more useful than 7.10, which was the first
Ubuntu that would actually install to my computer. I think that in a few
more iterations Ubuntu will displace Windows on my machines. But not yet.
So, what is compiz and how do I get the files to reinstall them?

Thanks Rob Backus

Hi
Compiz is a set of programs used for managing the desktop and enabling the
special effects. You use the Synaptic package manager to uninstall and
install them(and all your other software). If you do not know where that is
you find it in desktop menu under System>Administration>Synaptic Packager
Manager. This has a search utility and you can search for compiz and it will
list all the compiz packages on your system. You right click on the package
to get the list of available actions. All I did was choose the complete
uninstall option(removes all settings as well as the software) and then
reinstall. It seems that that did the trick. When doing this I was logged in
using the Gnome failsafe desktop which does not need compiz.

Hope this helps. By the way, once you get used to linux you'll love it. I
took windows off my system 2 years ago and don't miss it at all. Have fun.

Thanks for your email!!

I'm Spanish. I don't speak English very well.

I Know Ubuntu since four years ago, Compiz is not a
great problem for me.

Bye!!

Thanks for your email!!

I'm spanish and speak English bad.

I have the graphics Cards Ati Radeon 9200 Series. I
don't get an Output TV in Linux and this is my
problem, compiz is a secondary problem, Compiz crashed
when changed the monitor's resolution.

m1330 running w/ 8400gs happens every single time I resume from suspend and hibernation. Side note... would be nice to have boot screen in native wide screen instead of stretched.. no biggie though.

Thanks, of course I have no idea what the Gnome fail safe mode is.

I have been disatisfied with Windows for many years now, it is often buggy
and just really top heavy. I am really impressed with how Linux keeps
improving. For instance, Ubuntu 8.04 Beta is much better at reading my NTFS
files, which is critical for any transition. The biggest draw back at this
point is that more and more offices are going to Microsoft Exchange which
really locks one in. The IT guys at my office said it worked and it worked
well and nothing else out there does what it does. Damn.

Thanks Rob

This bug might be related. I opened it today because compiz.real was crashing as well as consuming 100% CPU.

https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/218721

I just restarted after upgrading to Hardy from Gutsy and the crashes are coming from all over the place

I rebooted again after disabling screenlets which was also crashing before and the crashes didnt happen this time

thanks! I'm not good at english, so I can't say more.

Are you able to reproduce this very crash in the current version 0.7.6-0ubuntu2? Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

Nope, I was trying to repeat the same sequence, and sometimes I've managed to reproduce it, but since the update the bug is not reproducible anymore - at least for me.

I am seeing a whitescreen on Hardy with 2.6.24-19-generic (linux-kernel package version 2.6.24-19.34). Inspecting /var/log/messages shows message like this:

Jun 26 06:17:40 host kernel: [ 1376.955900] compiz.real[6597]: segfault at 00000018 eip 08055a6d esp bfc060c0 error 4

Reverting to 2.6.24-18-generic (2.6.24.13-18.41) restores normal behavior. I have Radeon 9800PRO and xorg-driver-fglrx 1:7.1.9-8-3+2.6.24.13-19.42.

Sounds like this has been fixed.

Yes, I solved the problem by disabling compis.

Updated - restarted as requested - logged in - error reported before anything was done.
This is with Intrepid x86_64.

I was in Mozilla firefox typing in a google request. I doubt that this means much.
I have Intrepid x86_64 and Heron x86_64. Heron is ok, Intrepid is not.
Perhaps the following will help.
Video card - nvidia 8800 gtx
video driver - nvidia-glx-177 version 177.13-0ubuntu8
CompizConfig settings for Intrepid --
- under Accessibility - Negative
- under Desktop - Desktop Wall, Expo, Viewport Switcher
- under Effects - Animations, Fading Windows, Window Decoration
- nil under Extras
- under Image Loading - JPEG, Png, Svg, Text
- under Utility - Dbus, Regex Matching, Resize Info, Scale Addons, Scale Window Title Filter, Session Management,
Video Playback, Workarounds
- under Window Management - Extra WM Actions, Place Windows, Resize Window, Scale, Snapping Windows,
Static Application Switche
- under Uncategorized - Move Window
Let me know if you would like me to try changing any of thes settings.

Read mail and played solitaire in Heron. No problems. Booted and logged into Intrepid and entered mahjongg and made a few moves. Then the error. The effect I'm interested in is fading a window to see what's underneath.
