Debian Multimedia :: Segfault In Libxcb.so.1.1.0 Loading Plasma5
Sep 6, 2015
I'm having some trouble after the day 31 upgrade. Using the lightdm, kdm or sddm I'm unable to start a plasma session. Through dmesg I'm seeing that something is wrong with libxcb:
Code: Select all[ 3036.768102] drkonqi: segfault at 0 ip 00007fe39dce1a74 sp 00007ffce440bbb0 error 4 in libxcb.so.1.1.0[7fe39dcd7000+21000]

And I'm getting this in xsession-errors:
Code: Select allXsession: X session started for cris at Dom Set 6 12:17:01 WEST 2015

As usual when I want to install sid, I downloaded the "mini.iso" image and proceeded with the installation of sid, without problems. However, when rebooted I noticed SDDM was in place instead of KDM; I readly knew plasma5 was installed.
No messages appeared when I selected "KDE" from the installation process, nor there was a "plasma" name there. So can I install KDE4 desktop instead of plasma 5, using the mini.iso? (I don't like upgrades so telling me to upgrade from stable -> testing -> sid will be useless).
How do I get pSX working? I tried copying the psx.ini file from another machine because the thread says pSX works fine after you change the sound device used, but it still segfaults when I try running it.
I have tried to setup a workstation with 3 monitors on two ati videocards, the goal being to span the desktop across all of them.
The process was not difficult at all, but after login X11 crashes and I am left with a console. I am fortunately able to login in safe mode, but I would like to ask for help in debugging this issue.
Here I will try to give as much detail as possible, starting with my system specifications:
The first card, the ATI Radeon HD 4650 is capable of running two monitors at the same time. The monitors, for all it matters, are three identical ACER P206HV 20" connected with their analog interface (due to missing cables which I will buy soon). Resolution 1600x900 each. My motherboard is an AsRock 870 Extreme3 mounting an AMD Athlon II X4 640 3 GHz processor and 8 GB of RAM.
When asked by Ubuntu, I installed the ATI Caralyst driver version 11.6 and set it up for using Xinerama.
As I said, this setup works fine if I login in safe mode, but crashes X11 otherwise (even in classical mode - no Unity). By inspecting the logs (attached) I found this (notice the segfault)
As a test, I tryed to configure Catalyst without Xinerama, an this works, but of course I end up with two separate desktop, which is not what I want. In this mode, xrandr seems to work correctly
After some research I found that XRandR does not support desktop spanning over multiple GPUs, so Xinerama is the only way to go in my case. Since the two are not compatible with each other, after login in safe mode I see that XRandR is disabled
One more test consisted in disabling the XRandR module in the config files, as found in some posts: edits in /etc/X11/xorg.conf
Rhythmbox crashes on startup, Clementine crashes once I try to play any file, Banshee crashes after the first second of any file. Totem actually still works, but it's not a very satisfying media player. :P This occurred suddenly after working fine for, well, months. I read that I should check whether I have the standard up-to-date gstreamer/pulseaudio/liborc versions installed, this seems to be the case.
I just saw this message in the syslog and wondered if it could have anything to do with my previous problems with LXDE crashing:
Code: Select allSep 6 08:03:34 MyComputer kernel: [ 1003.788502] colord-sane: segfault at 21 ip b4de95ba sp b5609fb8 error 6 in libdbus-1.so.3.7.2[b4dbe000+4a000]
I have read a number of bug reports regarding this issue and it appears to go back about two years. It was supposedly fixed but that does not appear to be the case unless there is something peculiar with my Wheezy 7.8 installation.I just found this on a Ubuntu bug report. It is related to a colord-sane but not necessarily exactly the same as what I am experiencing.This is a libsane bug, not a colord bug. If you want to to work around it, change /etc/colord.conf to have UseSANE=false
I removed my .gnome and .nautilus folders and .notifier file. it is working now. I do not know exactly which of these 3 fixed it but I hope this might help someone else!I have some major issue with nautilus which is preventing me from loogging in into my system which is kind of criticle this weekend.I'm running Squeeze with latest updates.
The problem:Today gnome gave some problems caus my taskbar was suddently gone. I couldn't get it back to i reinstall gnome-desktop and updated my whole system. At the update some yes/no questions on a blue screen asking me to restart cups etc had corrupted yes/no buttons. Weird character sets were shown. Well that can happen sometimes i thought.After reinstalling gnome i can't login anymore. My screen keeps flashing while it shows the loading icon of the mouse.Anyone got suggestions? I can't find similar problems on the internet, only problems that happen while already logged in. In my case the segfault prevents gdm starting! Maurice
I have a problem with nautilus thumbnails since a few days. I checked they are indeed generated in .thumbnails, but all I got in nautilus is the "loading.." icon instead of the thumbnail, for all kind of files (pdf, image, video..) + a high cpu load.
I really don't see what to look at here, didn't found any trace of error in several logs/debug tool like gdb (and btw does nautilus have log abilities?)
I don't know which change could have triggered this (it used to work fine), maybe adding the i386 compatibilty with "dpkg --add-architecture i386" ? (I did this a few days ago in order to install acrobat reader)
Also I've been copying all of the home folder files from my previous ubuntu account to the new debian one, maybe I broke something in the process ?
I've had this odd, stubborn problem that seems to be related to the nouveau video driver and certain kernel builds: opening or saving full resolution jpeg image files using GIMP takes from 1-5 minutes and causes xorg CPU usage to reach almost 100%.This also occurs when using UFRaw to open Canon raw image files. The problem is not intermittent, it happens each time I open a file. Opening photos in the default image viewer works fine.This bug has vexed me on and off for the last couple of months, and seems to be triggered by a combination of kernel version and the Nouveau driver. I switched to Debian Squeeze from Ubuntu 10.04 because I was experiencing slow image open times in Ubuntu 10.04 (using the Nouveau driver).I did not experience the bug running Squeeze with the nv driver and kernel 2.6.32-3.
I did not have the bug running Squeeze with the nouveau driver and kernel 2.6.32-5 backported from Sid.I began experiencing the bug again after the Squeeze updates on June 14th (still running nouveau and kernel 2.6.32-5). I update daily so it's likely to be that day's updates which caused the bug to reappear.Just for grins, I installed the Liquorix kernel. The bug does not occur using kernel 2.6.34-0.dmz.10-liquorix-686 and the nouveau video driver.I have a Nvidia FX5500 video card. I prefer the nouveau driver to nv as my display seems to behave better. The Nvidia proprietary drivers are not an option because they produce X freezes when I am doing photo editing. The liquorix kernel seems to be working fine, but for long-term stability I'd rather be running a mainline Debian kernel.
I have recently taken delivery of a Dell Inspiron mini netbook with Ubuntu on, and I am new-fangled .install updates, I clicked the (orange down-arrow) button, and it compalined "E: /var/cache/apt/archives/linux-image-2.6.24-22-lpia_2.6.24-22.45netbook9_lpia.deb: files list file for package `libxcb-shape0' is missing final newline"
This is not directly for me since I don't have an iPhone. it opens automatically with DigiKam he said and that's the only available option in the device manager. All he can do is download photos from the phone. He is running openSuse 11.2 with KDE 4.4.2.
On Ubuntu 10.04, when I select Playlist -> Load From File and select a .m3u file in Rhythmbox, the playlist shows up but is totally blank. This is an m3u file exported directly out of windows media player 12 on a different computer, and when I open it with gedit, I can see all the tracks listed. Why is it blank? I've relied on this feature for almost two years and now it's suddenly gone!
I use to use amarok a lot back in the day and loved it. Saw that I could install it on ubuntu (which was a great suprise, since I though amarok was a KDE application).
Anyways, EVERY time I load amarok, I see it pop up for about 1 or 2 seconds and then my xserver (is that what it is called? the GUI portion of linux) crashes and restarts. EVERY SINGLE TIME. Open amarok, xserver crashes and restarts.
So, now we know where exactly the problem occures. I know only these three commands to debug using gdb. But in case of ns-2 code, I don't know how to use gdb.
I changed a routing protocol's C++ code in ns-2 and successfully recompiled ns-2 but when I run any tcl script with that particular protocol, I get 'segmentation fault'. Now I want to trace what part of the code is causing this. I have tried using 'printf's at suspectable places. Is this possible to debug ns-2 code with gdb just like the segfault.c above? I am useing fedora 9.
I am trying to write a peer to peer application in C++ using pthreads library. There are few types of nodes that run in the program. The 'beacon' nodes form the core of the network. The ordinary nodes 'join' the network by sending join requests to the beacon node. So, my program runs till the join requests and responses are received. When I try to 'connect' using connect function from the socket library, I get a segfault. I am not sure if the segfault occurs for the connect function, because sometimes the program just runs to completion. It could be an issue related to threads or memory allocation.
When I run gdb, it shows me the following: Code: (gdb) run b2-n00.ini Starting program: sv_node b2-n00.ini servant:12600> [New LWP 1] [New LWP 2] [New LWP 3] [New LWP 4] [New LWP 5] [New LWP 6] Before Exiting[LWP 1 exited] procfs: fetch_registers, get_gregs line 3768, /proc/23952/lwp/1: No such file or directory.
I usually use the following command to join several PDF files in one :gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=output.pdf input1.pdf input2.pdfHadn't have to do it for a while but today, I needed it and thus fired my script.lam! gs segfaults.A quick internet search and I found this :https://bugs.archlinux.org/task/22006Though Arch related, while I'm running slackware64-current, the behaviour was exactly the same as mine.In the above thread, one guy linked to a bug report which seems to be theculprit :http://bugs.ghostscript.com/show_bug.cgi?id=691831gcc 4.5.1, gs 9.00, x86_64, indeed, slackware64 seems to be exactly in that situation.
Has anyone had any luck getting a slackbuild to work with the newest version of skype 184.108.40.206? I tried with the static binary but when I go to execute skype I get a segfault. I also tried with a different slackbuild and it doesn't work either.
I have a custom program that has been running on Slackware since about 2004. It was running fine on Slackware 13.0, but an upgrade (following the procedure in UPGRADE.TXT) to 13.1 causes the program to segfault on a read/write op to the serial port (details here).
what might have changed between 13.0 and 13.1 that might affect serial port programming? I've been through CHANGES_AND_HINTS but nothing is jumping out at me.
I have a newly installed centos 5.5 x86_64 running as a guest on a xen environment. I've installed httpd, mysql, php, mod-php, cacti and some how mod-php i causing apache to exit with segmentation fault. I don't understand whats causing the problem, I have similar boxes with the same setup that works.
