http://bugzilla.opensuse.org/show_bug.cgi?id=1000976 Bug ID: 1000976 Summary: Screen remains blank after resume (intel) Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: cycomanic@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 694026 --> http://bugzilla.opensuse.org/attachment.cgi?id=694026&action=edit journalctl log I'm running TW on an Lenovo X1 Carbon (4th Gen). Every Nth time (where N is somewhat < 10), or after N hours (again difficult to specify) the screen remains blank after a resume. My suspicion is that this mainly happens after I unplug the monitor from the onelink+ dock (with 2 external monitors) and suspend. I have tried making sure that the laptop display is running before suspending, but the problem still persists. $ uname -r 4.7.4-1-default I've attached the relevant journalctl log from just before the suspend to after I pressed the power button to reboot the machine. I do see an error: [drm:intel_display_resume [i915]] *ERROR* Restoring old state failed with -22 which I suspect is what's happening, however I can't figure out what is causing this. -- You are receiving this mail because: You are on the CC list for the bug.
