It crashes for me too, whenever gnome-screensaver tries to lock the screen. The screen is locked, ie. I cannot interact with it, however it is not hidden - and there is window that pops out and informs about the abnormal termination of a process. I have to switch to console, login and kill process (gnome-screensaver), and after that I can interact with desktop once again.
I suspect "gnome screensaver helper gl" is incorrectly assuming I have access to OpenGL acceleration, which is not true. -- gnome-screensaver-gl-helper assert failure: gnome-screensaver-gl-helper: ../../src/xcb_io.c:542: _XRead: Afirmação `dpy->xcb->reply_data != ((void *)0)' falhou. https://bugs.launchpad.net/bugs/449216 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
