This seems to be a somewhat more general problem than just logging out from KDE; see bug #660152, which I suspect is a duplicate of this.
Now the fun begins. What appears to be happening is that FreeClientResources is being called on the server pseudo-client, which is perfectly reasonable. However, at some the resource list stored in clientTable[0].resources has become corrupted, and one or more of __GLXdrawables stored in there ends up with garbage values. When FreeClientResources hits this resource, DrawableGone from glx/glxext.c is called on the corrupted __GLXdrawable and explodes somewhere, either with a bogus pDraw or calling an invalid ->destroy(). I've traced through the resource code, and these __GLXdrawables are perfectly valid when they're getting added to the resource list. Furthermore, nothing from the resource code seems to be fiddling with them; it looks like some unrelated code is *sometimes* scribbling over *some of* the values in memory. -- X crash on KDM logout (still - yes, really) https://bugs.launchpad.net/bugs/651294 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
