Well, it's just garbage. Attached anyway. When the "screen lock" password prompt screen starts it's completely garbled. When I blind-type in the password, the desktop shows up and it looks kind of OK until a new window is opened and then it looks like rectangular area full of horizontal lines. > Also, does a vt-switch not resolve the issue? No, switching VTs back and forth doesn't help when this happens (it makes things worse actually). It's not 100% reproducible (but close to that on the IVB machine) and I've seen it once on my other machine based on Sandy Bridge too. Thanks, Rafael -- I speak only for myself. Rafael J.
