Writing to the gtk textview buffer crashes xorg

[Florian Köberle]

Woraround: Use the opensource or the nvidia-legacy driver

Activate the description expander in update-manager to get a crash.

the only package wich is marked for update is kate. Maybe the kate update has a desciption text which crash the xserver. (the update function has worked yesterday)

[Florian Köberle (iflo)]

the update manager has two tabs:
"Änderungen" (changes) and "Beschreibung" (description)

When I click on "Beschreibung" tab before the changes text is loaded then the xserver doesn't crash. After this i can click the "Änderungen" tab without a crash.

This is most likely a bug in the graphic driver. Which one do you use? Do you use a binary-only driver like fglrx or nvidia?

[Florian Köberle (iflo)]

I use still the Package nvidia-glx as grapthic driver. (See comment in: https://launchpad.net/distros/ubuntu/+source/xserver-xorg/+bug/47122)

[Florian Köberle (iflo)]

When i use nv as graphic driver it works without crash.

[Martin Pitt (pitti)]

Hm, there is little we can do then, I'm afraid.

[Florian Köberle (iflo)]

with the current (2006-07-06) update it is the same. ("Clicking the description tab" to avoid the x-Server works here too)

packages marked for update: login, passwd, ppp

"Activate the description expander in update-manager to get a crash."

Thats not true for me!!!!!!!!! (The Reporter of the Bug)

It doesn't crash when I click on the description expander! (thats the way how to avoid this bug)

The only thing I have to do to produce the crash is starting the updatemanager. (when i am fast and click the description expander it doesn't crash. Even when I click later on the changes expander.)

It seems this bug has been reported to upstream at http://www.nvnews.net/vbulletin/showthread.php?t=73033. AFAIK those are the "official" Nvidia/Linux forums.

From that post, it seems this bug is actually a duplicate #47122

[Lukas Winter (webmaster-geloescht)]

After switching to nvidia-glx-legacy instead of nvidia-glx, the crash disappeared for me (both drivers support my card). So the older driver did not have this bug.

Lonni from Nvidia gave a super quick reply after I shot of a mail to linux-bugs, after filing a report here (turned out to be a dupe of this report, dont know how I missed this one)

There is a post on nvnews tracking the status of this bug, so I tought it relevant to post a link to it here

Today I got again this bug. Seems each time some packedes from KDE are involved. Updating via apt-get. I believe each time it happens something of KDE needs to be updated!

Instellen van kdelibs-data (3.5.2-0ubuntu18.1) ...

Instellen van kdelibs-bin (3.5.2-0ubuntu18.1) ...
Instellen van kdelibs4c2a (3.5.2-0ubuntu18.1) ...

[David Planella (dpm)]

I don't think it's got anything to do with kde packages.

Although I got the same issue yesterday when upgrading the kde packages, last time I saw this, it happened to me when updating a kernel package.

[Alan (alanrr-sr-yahoo)]

I am getting this error to...same steps as decribed by Florian Köberle:
- click on the update icon
- enter your password
- wait unitl it is loaded
- without doing anything, you should get now the login promt (xserver has crashed)

The error is not continum for me. It happens a lot of time, but sometimes everything works fine.
Extra detail: Nvidia user too and 2 Xservers.

Fixing up package name, but note that this bug was originally reported on the nvidia-glx binary package.

[Florian Köberle (iflo)]

When it is the same bug like this:
https://launchpad.net/distros/ubuntu/+bug/47122

then there are three ways of avoiding this bug:
- install the most current NVIDA driver( >= 1.0-8776): http://www.nvidia.com/object/linux_display_ia32_1.0-8776.html
- install the beta driver of NVIDIA(>= 1.0-9625):
http://www.nzone.com/object/nzone_downloads_linux_display_x86_1.0-9625.html
- use the "nv" driver instead of "nvida"

If this is the case, then there is a exploit for this bug!

[Phil Bull (philbull)]

Have there been any developments with this bug? Does anyone still have this issue?

I'm rejecting this bug for now, as it seems to be due to a closed-source package we have no control over. Please feel free to reopen the bug if you have any further information.
