When a GPU gets hotplugged while X is already running, glamor_egl_init() gets called and changes the current egl context, without updating lastGLContext, potentially causing the next glamor call on another GPU to run in the wrong context. This causes glamor to e.g. crash in the next glamor_create_pixmap() call (called through the master's screen->CreatePixmap), note this is not the only troublesome entry point I've seen other backtraces when using a compositing window manager. Set lastGLContext to NULL to force the next glamor_make_current() call to set the right context. Note that we cannot use glamor_make_current() here to replace the eglMakeCurrent() call and update lastGLContext for us because glamor_make_current takes a glamor_priv struct as argument and that has not been created yet when glamor_egl_init() gets called.

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: http://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: http://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver http://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: http://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: http://wiki.x.org/wiki/GitPage
