Randomly crashes. ( Or -- I just didn't find out what crashed it! )

Direct Rendering works...

Nothing significant happens in the duration thereof.

It seems to be a bug of recent x-servers (xorg), sometimes moving or resizing some window is killing opengl applications. Can't do something against that since it's done by the x-server and is killing the application without a notice, but I will try to find some more information about it since its annoying like hell.

Hrm -- I've been trying to solve this too...

I had beryl-manager on at the time of the crashes without XGL on. ( I closed it because direct-rendering didn't work as effectively while it was opened, I had to DISPLAY=:0 graal to have it ). When I removed the beryl-manager from the session, it seems to have fixed the problem. I don't know why it was doing it: It was pretty inactive as application.

[Novo]

Bah! Still crashes... But at a MUCH lesser frequency ( without beryl-manager )

Novo, what window manager are you using? I've had this bad window position error a lot with KDE, but not at all with WindowMaker or Gnome.

According to Stefan, it's not the windows manager that actually breaks it -- It's the recent update on the X-Server -- Both Gnome and KDE are based on this.

I suppose some windows managers fall on the bug more often though ( Beryl probably crashed so much more due to it being enhanced graphically, and uses a lot more exploitation in the system )

Okay. I'm going to upgrade to the latest X.org server (I was running a slightly older version I'm now upgrading to xorg-x11-server-7.2-56.1.i586 on SUSE 10.1) and see how if it makes any difference in those crashes.

[Questa]

Okay. I upgraded my X.org server and now I get a segmentation fault when opening Graal. Just like I did in this thread. So Stefan, if you are wondering what's causing segmentation faults in Intel graphics accelerators, it's most definitely the newest version of X.org.

But glxinfo and other opengl programs still work?

Yeah, they work great. glxgears gets an awesome framerate and 3D games work too.

[Admins]

Hmmm I can only imagine that there is some special OpenGL command not supported. When its crashing at startup, you still get a ~/.graal/graal4/console.log ?

About the random linux crashes, I have reduced the problem by not redrawing the window when some special events occur, so the next Graal version should work a little bit better.

[Admins]

Ok fixed it. It was quite hard to find because Xerrors are normally not printed when they are happening, so we had to set the XServer to synchronized mode.
