[Kernel-packages] [Bug 1527829] Re: displayport MST external monitors don't return from sleep mode
Additional info: When in intended setup (two monitors on one DP) the ASUS brand monitor flickers occasionally (not a nuisance) - Connecting just the ASUS to the adapter (other HDMI port unpopulated) the monitor flickers repeatedly, indefinitely, often. This is regardless of which of the 2 ports it's on. I have attached verbose (drm.debug=0x05) kernel logs of this behavior - Connecting just the samsung (second external monitor) to the adapter works fine, and when going to powersave using "xset dpms force off" monitor stay off, although the external monitor doesn't come on after resume (topic issue), confirmed multiple times So it seems like the ASUS is causing all monitors/panel to wake up ~15s after display standby. In the attached log, the monitor cycling on/off happens 5 times ** Attachment added: "cycling-onemonitor.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1527829/+attachment/4549558/+files/cycling-onemonitor.tar.gz -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1527829 Title: displayport MST external monitors don't return from sleep mode Status in linux package in Ubuntu: Confirmed Bug description: When displays go to sleep, upon return from sleep the two monitors attached to a belkin mini displayport to 2x HDMI, do not return from sleep.

[Kernel-packages] [Bug 1527829] Re: displayport MST external monitors don't return from sleep mode
the drm-intel-nightly kernel didn't fix the issue. I began attempting to trace the issue and search for clues as to why this is happening. I am attaching three kernel log files with kernel switch: drm.debug=0x05 All of these are kernel logs after a "xset dpms force off". - "success" is with the screen resumed successfully after a few seconds of being suspended - "fail-proper" screen resumed after ~20 seconds, and the issue occurs - "fail-reschg" after about 15 seconds, the computer wakes itself with no user input, external monitors are switched off, and the panel (eDP) drops to 1680x1050 and cannot be set to a higher resolution until a "service lightdm restart" I noticed the existence of errors around "set_hdr_from_dst_qlock" in fail-proper only and came across two patches to drm_dp_mst_topology.c - I applied these four patches and recompiled the kernel module, and the problem still exists. http://www.spinics.net/lists/stable/msg113900.html After this patch it seems like suspending does one of three behaviors: - Wakes itself after 15 seconds with no issues - Wakes itself after 15 seconds and the externals detach, and laptop panel goes to a lower resolution - Doesn't wake, but on user input returns with the two external screens still part of the desktop, but with no video ** Attachment added: "verboselogs.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1527829/+attachment/4549545/+files/verboselogs.tar.gz ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1527829 Title: displayport MST external monitors don't return from sleep mode Status in linux package in Ubuntu: Confirmed Bug description: When displays go to sleep, upon return from sleep the two monitors attached to a belkin mini displayport to 2x HDMI, do not return from sleep.

[Kernel-packages] [Bug 1527829] Re: displayport MST external monitors don't return from sleep mode
Derek, at your earliest convenience, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

[Kernel-packages] [Bug 1527829] Re: displayport MST external monitors don't return from sleep mode
Derek, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/19/product- support/product/xps-13-9333/drivers/advanced an update to your computer's buggy and outdated BIOS is available (A08). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-a08 ** Package changed: xserver-xorg-video-intel (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1527829 Title: displayport MST external monitors don't return from sleep mode Status in linux package in Ubuntu: Incomplete Bug description: When displays go to sleep, upon return from sleep the two monitors attached to a belkin mini displayport to 2x HDMI, do not return from sleep.
