http://bugzilla.opensuse.org/show_bug.cgi?id=968354 Bug ID: 968354 Summary: Missing secondary display with Kernel 4.4 on Sandybridge Classification: openSUSE Product: openSUSE Tumbleweed Version: 2015* Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: kairo@kairo.at QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- With the openSUSE Tumbleweed update to kernel 4.4, my secondary display went dark. This is on a Sandybridge graphics system (i7-2600K) with an Intel mainboard (DH67CL), the same problem persists with 4.4.1 and 4.5-rc1 kernels from OBS (Kernel:Stable and Kernel:HEAD), while a 4.3.3 from home:tiwai:kernel:4.3 makes the display connected to "HDMI2" (actually the DVI connector) work again fine - the main display on "HDMI1" (HDMI connector of the mainboard) works fine with all those kernel variants. I filed https://bugs.freedesktop.org/show_bug.cgi?id=94299 for this as well on the upstream side. -- You are receiving this mail because: You are on the CC list for the bug.
