Public bug reported: Every now and then, maybe one time out of 8, resuming from suspend gives me a black screen, no X.
If I try ctrl-alt-F7, I see a VT with a _ on it, no X or login prompt. If I try ctrl-alt-F1, F2, F2 or F4, X crashes, every time. I've collected X logs from the last two times this has happened; both times, there's a message near the end: EnterVT failed for screen 0 I found a similar but not identical upstream bug: that might be related: https://bugs.freedesktop.org/show_bug.cgi?id=109668 There's also a Redhat bug that looks related and might have helpful info: https://bugzilla.redhat.com/show_bug.cgi?id=1662057 Machine is a Levono Carbon X1 with Intel graphics (hopefully ubuntu-bug attached the relevant info).
