http://bugzilla.opensuse.org/show_bug.cgi?id=1140573 Bug ID: 1140573 Summary: External monitor stops working when coming back from screen save mode (with docking station) Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: vuntz@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I have a new laptop (Dell Latitude 7290) with a dock (Dell WD15), and two external monitors plugged in the dock. Every now and then, when I come back to the computer after a while, one monitor (and sometimes both) fails to wake up. I didn't find a way to restore things -- usually, I end up with no screen at all with my attempts, even when unplugging from dock...
