After resume from suspend, the screen shows part but not all of its pre-suspend contents (most often the menu used to enter suspend) on a black background, or sometimes garbage or all-black, instead of the password entry screen. This does not happen on resume from screen lock.
I haven't tried entering my password, as I can't see what I might be giving it to; Alt+SysRq+b reboot works.
Ubuntu Trusty (libdrm-nouveau 2.4.52, xserver-xorg-video-nouveau 1.0.10, mesa 10.1.0); kernels 3.13 (default), 3.14rc8 (git as of 26 Mar), 3.11 and 3.8 are all affected.
This is the same machine as bug 71659, but the system logs don't have its error message.
