[KScreen] [Bug 366346] Lenovo T460s + Docking station = external displays are broken with Plasma 5
https://bugs.kde.org/show_bug.cgi?id=366346 rubin110 changed: What|Removed |Added CC||[email protected] --- Comment #36 from rubin110 --- I'm also seeing something similar with plasma-desktop 5.7.4 on Debian Sid with a Thinkpad X1 Carbon 4th Gen, a Thinkpad Onelink+ dock, and a few different DisplayPort displays plugged into the dock. KDE doesn't auto-enable the desktop display after the OneLink+ dock has been plugged in. Checking kscreen-doctor -o I see the port is still disabled with no listing of geometry. I have to either open up the display settings panel and enable it there (and yes it's listed there) or do something like xrandr --output DP-2-2 --auto --right-of eDP-1 to bring it up (and also yes, the display is listed under xrandr -q without any other tickling). When I unplug the OneLink+ dock, I can still move my mouse past the edge of my laptop screen and go into the part of the desktop that was created for the 2nd display. The display settings panel only shows the laptop display, and xrandr -q shows the port as being displayed but shows the last known geometry for that port. Doing an xrandr --output DP-2-2 --off will remove the ghost portion of the desktop. And yes I acknowledge the fixes listed here are being pushed out to 5.8. Just figured documenting my experiences might be good. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=366346 --- Comment #30 from Hai Zaar --- Tested on Neon unstable release from Aug 21. The screens resolution is detected properly now - verified on two slightly different docking setups. The only issue, though not sure if it's related, is with visual positioning of screens in kscreen UI - after re-plug, the second screen always jumps to the top. Note that his is only a visual representation issue - the actual desktop is positioned just fine, i.e. if I pass mouse cursor from left to right, it passes all of the three screens on the same height. See the before/after screenshots. Many thanks for fixing this! These changes will make it only to Plasma 5.8, right? P.S. I've sent you email with couple of questions on the future of HIDPI in KDE couple of weeks ago - chances are it got to spam. I'll truly appreciate if you'll have a look. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=366346 Hai Zaar changed: What|Removed |Added Status|RESOLVED|REOPENED Resolution|FIXED |--- --- Comment #25 from Hai Zaar --- Tested on neon-devedition-gitunstable-20160810-0806-amd64.iso There is a good progress, but it's still not perfect. When replugging, displays are recognized and lit up, but one of them has wrong resolution. After going to screen settings, I'm able to set the right resolution and it works, but after another unplug/plug cycle, the resolution is not recognized properly once again. The exact flow: 1. Plug into docking after boot. 2. Displays are detected with proper sizes and ARE ENABLED automatically (in previous version they were not) 3. Unplug from docking. 4. Wait for displays to disappear from screen config tool. 5. Grab kscreen.log.before-plug 6. Plug into docking - displays are detected and enabled (lit up). However the one that is connected through DP->HDMI cable is configured with wrong (smaller) resolution. Grab kscreen.log.after-plug-wrong-resolution Again, adjusting resolution after step 6 through config tool fixed it, but step 6 reproduces through another unplug/plug cycle. -- You are receiving this mail because: You are watching all bug changes.

Committed on 09/08/2016 at 12:20. Pushed by sebas into branch 'master'. [kded] fix monitoring for newly appearing outputs Summary: This patch makes the kded daemon monitor also newly connected outputs, and leads to correctly initialize outputs from a docking station plugged in after session start. For "internal" display connector ports (HDMI, DisplayPort, etc. integrated in the system, we know from the start that they exist. These are marked disconnected. When plugging in a docking station, new outputs (that aren't previously known as disconnected) appear. daemon.cpp only monitors outputs that change connection state, so it doesn't consider newly added outputs. By listening to KScreen::Config::outputAdded, we can detect new output (connectors) as well, so we can trigger the applyConfig code path, which leads to restoring the config. Test Plan: * Reproduced the issue in https://bugs.kde.org/show_bug.cgi?id=366346 and confirmed it fixes the problem on my system (Lenovo Onelink+ docking station which shows the same behaviour). * Added debug calls and confirmed the new outputs are correctly set up. auto-testing this seems to be close to impossible. :/ Reviewers: #plasma, davidedmundson, graesslin Reviewed By: #plasma, davidedmundson, graesslin Subscribers: plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D2374 M +10 -0kded/daemon.cpp http://commits.kde.org/kscreen/68423ccdf3f89e4bbaa53117aff067471455c0a3 -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=366346 Sebastian Kügler changed: What|Removed |Added Version|5.7.2 |git Keywords||multiscreen --- Comment #21 from Sebastian Kügler --- Thanks a lot for the detailed information, it's very useful. Interestingly, the clue is in the log lines that are missing in your kscreen.log. :) The kscreen daemon (kded module) loads a list of outputs on startup and starts watching these for the Output::isConnectedChanged signal. What's happening when you plug in the dock after the session was started (and these outputs initialized) is that new output "connectors" appear -- these are initially disconnected. Then a configChanged signal arrives, and kscreen saves the config -- with disabled outputs. This means the configuration from this point won't work anymore until you manually enable the output again. You can check which outputs are known at all, and which are connected easily with "kscreen-doctor -o" (kscreen-doctor is a small debugging/testing tool I've been working on lately.) I can reproduce this behaviour on my laptop when plugging in a Lenovo Onelink+ docking station. Completely new outputs appear when the docking station is plugged in. The fix is pretty simple: we hook up Config::outputAdded as well, and make apply a known configuration (this was exactly what was omitted in case the docking station appears after startup). I've posted this fix for review on phabricator: https://phabricator.kde.org/D2374 . Once this (or a variation of it) is merged, it would be cool if you could give it another try and see if the change fixes the problem for you. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=366346 --- Comment #20 from Hai Zaar --- Oh, I thought you want to see how these displays are detected when I plug into docking. The exact flow was: 1. Plug into docking after boot. 2. Displays are detected with proper sizes, but are disabled. Enable them. 3. Unplug from docking. 4. Wait for displays to disappear from screen config tool. 5. Move kscreen.log aside 6. Plug into docking - displays are a detected, but shown small with unknown resolution (as in my previous screenshot) At this point I've grabbed the new kscreen.log and posted it. Enabling displays later on was unsuccessful - configuration utility showed error dialog saying something like "Can not apply your screen configuration due to incorrect resolution" (Don't remember the exact wording and I'm not near the computer right now). I'll retest tomorrow and will send you the updated log file. P.S. The last line in the current log is saying QSize(-1, -1). Is this normal? Shouldn't KDE recognize the size properly even-though the screen is disabled?
