Hello Dhinakaran, I tested it again and was able to easily reproduce it on SKL with MST hub connected directly to DP, in the output side I only connected ONE DP display and nothing else. Then I disconnected the DP cable and when I connected it again the login screen appears in display, no sound reproducing. Then I logged in and the terminal was closed as described in <a href="show_bug.cgi?id=101314#c1">comment #1</a>. ====================================== Software ====================================== kernel version : 4.14.0-rc2-drm-tip-ww39-commit-f4bd0d1+ architecture : x86_64 os version : Ubuntu 17.04 os codename : zesty kernel driver : i915 bios revision : 5.6 bios release date : 09/29/2016 ====================================== Graphic drivers ====================================== mesa : 17.0.3 modesetting : modesetting_drv.so xorg-xserver : 1.19.3 libdrm : 2.4.81 cairo : 1.14.8 xserver : X.Org X Server 1.19.99.1 intel-gpu-tools (tag) : intel-gpu-tools-1.18-211-g00ce341b intel-gpu-tools (commit) : 00ce341b ====================================== Hardware ====================================== platform : SKL Canyon motherboard id : NUC6i7KYB form factor : Desktop cpu family : Core i7 cpu family id : 6 cpu information : Intel(R) Core(TM) i7-6770HQ CPU @ 2.60GHz gpu card : Intel Corporation Iris Pro Graphics 580 (rev 09) (prog-if 00 [VGA controller]) memory ram : 31.31 GB max memory ram : 32 GB display resolution : 1600x900 cpu thread : 8 cpu core : 4 cpu model : 94 cpu stepping : 3 socket : Other signature : Type 0, Family 6, Model 94, Stepping 3 hard drive : 223GiB (240GB) current cd clock frequency : 450000 kHz maximum cd clock frequency : 675000 kHz displays connected : DP-5 ====================================== Firmware ====================================== dmc fw loaded : yes dmc version : 1.26 guc fw loaded : NONE guc version wanted : 0.0 guc version found : 0.0 ====================================== kernel parameters ====================================== quiet splash fastboot drm.debug=0xe</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
