If your compositor crashes something should take over, either fbdev (which force-restores) or a new compositor (system one or just the one that crashed, restarted). And on modern userspace logind has copies of the fds which it uses to make sure priviledges (i.e. master rights) don't escape to the wrong person. > For me this is serious enough not to go this route. If that doesn't happen you have yet another bug in userspace. I don't think there's a real problem really. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
