Broken driver installation, the only way to run into indirect rendering would be an explicit "LIBGL_ALWAYS_INDIRECT=1" export (bad idea on MESA, ignored on nvidia) or the software rasterizer. What's the output of "glxinfo" (unless that crashes as well) and "lspci" OK, I’ve solved the issue.
# glxinfo | grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL version string: 2.1 Mesa 8.0.4
OpenGL shading language version string: 1.20
"OpenGL 3.1" was selected as composite type in the "Erweitert" ("Advanced") tab, whereas glxinfo tells me that I have 2.1. I’m not sure, if I changed this setting or if it was automatically done. As far as I remember, the OpenGL version numbers in the dropdown are new as of KDE 4.11?
When I select OpenGL 2.0 or 1.2 instead of 3.1 everything is fine.
However, kwin should not crash when the incorrect OpenGL version is selected. Moreover, kwin should be able to figure out the correct version itself.
You are really using openSUSE 12.2? In that case your drivers are just way too old. I think we need to notify the openSUSE developers that it's a bad idea to provide 4.11 for such an old base I think I‘ll do a system update soon (maybe on new hardware). But I don’t think, that’s the point here. Even if it might be a problem with the driver, kwin should not crash. As I wrote before, I think, kwin should handle such situations gracefully. And maybe detect best – or at least a compatible – composite type/OpenGL version itself. KWin has made good progress in the last couple of years. But in the past, KDE has lost some good reputation also due to harmless crashes like this one. So maybe it’s worth fixing this issue. > But I don’t think, that’s the point here.

No, we cannot expect that distros provide KWin for outdated systems. It's the
task of the distribution to integrate the software. If they combine with a too
old stack it's the distribution's fault.
does that mesa version have the context attrib arb? can you please attach the output of glxinfo for that matter? in general it's impossible to know whether a call to another lib will crash that call, if you know a way to do that in general, please share it. this could be a weird variant of bug #327310 > in general it's impossible to know whether a call to another lib will crash

Ok, but it should be possible to determine the OpenGL version of the system and only make API calls compatible with that version. I don’t think users should have the option to choose an OpenGL version that is not even supported by their system.

Welcome to the world of OpenGL - you need to use OpenGL in order to get the
version. The fault here is clearly in openSUSE though and we cannot and should
not try to workaround it. Any up to date version will not crash, so why fix. If
you want to have that fixed, please contact your distribution.
Had GLX_ARB_create_context, GLX_ARB_create_context_profile in Client. Direct rendering is enabled, so there's hardly a legal way to end up in __indirect_glGetString This will indeed be a funky freaky version of bug #327310 About the ability to select some OpenGL version - any detection in the config dialog is as Martin pointed out unfortunately prone to crash the config dialog - so not an option at all. The problematic call *is* compatible with the driver and supported OGL variant. The GL server is supposed to know that a context with the requested attributes is not supported, so not create one and return a null pointer to allow the GL client to go on - that's what the extension exists for in the first place. For this very specific case one could indeed omit the attempt to create a core profile context, because a) the known GL version can predict what the server is supposed to do with the call b) we now know that "supposed" is not equal to "will" in this case but that's nowhere near a general solution, but just hacking around a broken driver. And just for the record, I cannot recall a longer time where there was not the "driver bug of the season". *** This bug has been marked as a duplicate of bug 327310 *** |
Application: kwin (4.11.4) KDE Platform Version: 4.11.4 Qt Version: 4.8.5 Operating System: Linux 3.4.11-2.16-desktop x86_64 Distribution: "openSUSE 12.2 (i586)" -- Information about the crash: Crash when activating desktop effects after updating KDE to version 4.11 (X11 packages might have been updated, too, via system update. Not sure.). Effects were disabled when I first started KDE after the update. Before the update, effects were enabled and working. I consider this a regression,, because desktop effects/compositing had been working almost flawlessly for a long time. What I was doing when the application crashed: I checked "Ich habe meine Daten gespeichert" ("I have saved my data"). Then I pushed "OpenGL-Erkennung aktivieren" ("Activate OpenGL detection"). The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
