Monday meeting minutes for 2019-01-28 (week 5)

[Eike Hein]

d_ed
====
‎I did a few little bug fixes, mostly in the cursors KCM
‎In bigger changes, my patch supporting shadows in KWindowSystem is 
nearly done
‎That reminds me. I had a tiny compositor written in kwayland that used 
to recreate the firefox issue
‎Firefox now works there !
‎...but still fails in kwin
‎so it seems something in FF has been fixed accidentally - but we now 
still need to revisit everything on the kwin side


notmart
=======

Kirigami
* Fixed a bug in PageRow whenre replacing the first page didn't work and 
just gave an empty window
* Merged Collapsible drawer items branch
* started a partial reimplementation of PageRow in C++ (to optimize 
memory consumption and fix some bugs that are tricky with qml-only, as 
well as features
* fixed paddings in SwipeListItem
KWin
* continued patches for wayland virtual desktops rows, accepted and landed


romangg
=======

Decided to move pushing my Xwl DND patches to next week to wait for 
after Frameworks release.
Have patches for improved Wayland backend on phab: D18465
 Diff 18465 "[platforms/wayland] Multi output support" [Needs Review] 
https://phabricator.kde.org/D18465
Patch for Xwl Multi DPI: D18486
 Diff 18486 "[RFC] XWayland Multi DPI support" [Needs Review] 
https://phabricator.kde.org/D18486
some other patches are on review which I will push in the coming two 
weeks. Currently looking into xdg-output support to Weston.
which might come in handy for testing multi dpi.


bshah
=====

- Preparing qt5.12 in neon, landing tomorrow at best
- Preparing for PlaMo sprint
- Rebased dmabuf patches to recent master for testing by community 
member on Librem 5 devkit


Sho
===

I cleaned up the libtm code on master to use the new rows API in the PVD 
Wayland protocol and dropped the D-Bus codepath again
I'm looking into some Folder View model bugs now, hoping I find the time 
to get fixes in before 5.15 is tagged
My new laptop has a decent nVidia DGPU. I tried testing nVidia's 
eglstreams backend patch (D18570) just before the meeting, but kwin is 
crashing during the splash screen. I'll debug


Next meeting todos: Schedule 5.16 kickoff; put dmabuf patches into 5.16 
task list


Cheers,
Eike
‎[20:07] ‎<‎Sho_‎>‎ I'll do notes
‎[20:07] ‎<‎Sho_‎>‎ d_ed: gogogo
‎[20:08] ‎<‎d_ed‎>‎ I did a few little bug fixes, mostly in the cursors KCM
‎[20:08] ‎<‎d_ed‎>‎ In bigger changes, my patch supporting shadows in KWindowSystem is nearly done
‎[20:08] ‎<‎Sho_‎>‎ supporting shadows in kws?
‎[20:09] ‎<‎Sho_‎>‎ sounds interesting, what does it entail :)
‎[20:09] ‎<‎d_ed‎>‎ effectively moving the code from Plasma::DialogShadows and Breeze::ShadowHelper / Oxygen::ShadowHelper into KWS
‎[20:09] ‎<‎Sho_‎>‎ neat
‎[20:09] ‎<‎d_ed‎>‎ main reason is that it's plugin based which is a pre-requisite for some changes Martin is doing in kwin with the internal windows
‎[20:09] ‎<‎notmart‎>‎ KWS?
‎[20:10] ‎<‎d_ed‎>‎ KWindowSystem
‎[20:10] ‎<‎notmart‎>‎ ah, kwindowsystem
‎[20:10] ‎<‎notmart‎>‎ neat :)
‎[20:10] ‎<‎Sho_‎>‎ d_ed: did the Fedora-defaulting-to-Firefox-Wayland news stir up anything, e.g. Firefox fixing anything or someone reaching out to you?
‎[20:10] ‎* ‎bshah‎‎ around
‎[20:10] ‎<‎d_ed‎>‎ Sho_: That reminds me. I had a tiny compositor written in kwayland that used to recreate the firefox issue
‎[20:10] ‎<‎d_ed‎>‎ Firefox now works there !
‎[20:10] ‎<‎d_ed‎>‎ ...but still fails in kwin
‎[20:11] ‎<‎Sho_‎>‎ Interesting
‎[20:11] ‎<‎notmart‎>‎ duh
‎[20:11] ‎<‎d_ed‎>‎ so it seems something in FF has been fixed accidentally - but we now still need to revisit everything on the kwin side
‎[20:11] ‎<‎Sho_‎>‎ :) at least it looks like it's something under our control then
‎[20:12] ‎<‎Sho_‎>‎ getting a wayland-native browser will be great ...
‎[20:12] ‎<‎d_ed‎>‎ yeah definitely
‎[20:12] ‎<‎Sho_‎>‎ got anything else, or should we move on to notmart?
‎[20:12] ‎<‎d_ed‎>‎ lets move on
‎[20:12] ‎<‎notmart‎>‎ ok
‎[20:12] ‎<‎Sho_‎>‎ notmart: gogogo
‎[20:12] ‎<‎Sho_‎>‎ this meeting directive not sponsored by Google Go

‎[20:15] ‎<‎Sho_‎>‎ romangg would be next, if you're done
‎[20:15] ‎<‎notmart‎>‎ yes
‎[20:15] ‎<‎Sho_‎>‎ romangg: gogogo
‎[20:15] ‎<‎romangg‎>‎ Decided to move pushing my Xwl DND patches to next week to wait for after Frameworks release.
‎[20:16] ‎<‎romangg‎>‎ Have patches for improved Wayland backend on phab: D18465
‎[20:16] ‎<‎sKreamer‎>‎ Diff 18465 "[platforms/wayland] Multi output support" [Needs Review] https://phabricator.kde.org/D18465
‎[20:16] ‎<‎romangg‎>‎ Patch for Xwl Multi DPI: D18486
‎[20:16] ‎<‎sKreamer‎>‎ Diff 18486 "[RFC] XWayland Multi DPI support" [Needs Review] https://phabricator.kde.org/D18486
‎[20:17] ‎<‎romangg‎>‎ some other patches are on review which I will push in the coming two weeks. Currently looking into xdg-output support to Weston.
‎[20:17] ‎<‎romangg‎>‎ which might come in handy for testing multi dpi.
‎[20:17] ‎<‎romangg‎>‎ any questions?
‎[20:17] ‎<‎Sho_‎>‎ basic question, but multi-output in what sense?
‎[20:18] ‎<‎Sho_‎>‎ so you can do multi outputs in windowed kwin_wayland?
‎[20:18] ‎<‎romangg‎>‎ yes
‎[20:18] ‎<‎Sho_‎>‎ that's terribly neat
‎[20:18] ‎<‎romangg‎>‎ yea, would be nice for testing.
‎[20:18] ‎<‎d_ed‎>‎ RE: 18486 can you split out the rendering smoothing changes
‎[20:19] ‎<‎d_ed‎>‎ as they should be relevant without xwl
‎[20:19] ‎<‎romangg‎>‎ Sho_: you can see it here: https://www.youtube.com/watch?v=FYItn1jvkbI
‎[20:19] ‎<‎romangg‎>‎ d_ed: Yea, I'm just not sure if it's the right solution.
‎[20:20] ‎<‎Sho_‎>‎ romangg: I actually saw the video, but didn't follow the implication :-)
‎[20:20] ‎<‎romangg‎>‎ d_ed: maybe you can give your imponion to https://phabricator.kde.org/D18486#inline-102319
‎[20:20] ‎<‎sKreamer‎>‎ Diff 18486 "[RFC] XWayland Multi DPI support" [Needs Review] https://phabricator.kde.org/D18486
‎[20:20] ‎<‎d_ed‎>‎ romangg: I want to test with the fractional scaling
‎[20:20] ‎<‎romangg‎>‎ *imponion == opinion :D
‎[20:20] <-- DavidRedondo (~davidredo@194.94.98.184) has left this server (Quit: Leaving).
‎[20:20] ‎<‎Sho_‎>‎ r/nottheonion
‎[20:21] ‎<‎romangg‎>‎ d_ed: yea, would be good thing to test.
‎[20:21] ‎<‎romangg‎>‎ I didn't yet.
‎[20:21] ‎<‎romangg‎>‎ Any other questions? otherwise next
‎[20:21] ‎<‎Sho_‎>‎ bshah: gogogo
‎[20:22] ‎<‎bshah‎>‎ - Preparing qt5.12 in neon, landing tomorrow at best
‎[20:22] ‎<‎bshah‎>‎ - Preparing for PlaMo sprint
‎[20:22] ‎<‎bshah‎>‎ - Rebased dmabuf patches to recent master for testing by community member on Librem 5 devkit
‎[20:23] ‎<‎bshah‎>‎ done :)
‎[20:23] ‎<‎bshah‎>‎ That said
‎[20:23] ‎<‎bshah‎>‎ What's blocking dmabuf patches?
‎[20:23] ‎<‎bshah‎>‎ it's fairly disappointing that code is on phab from ~1 year
‎[20:23] ‎<‎Sho_‎>‎ Indeed, and I think there was even some follow-up protocol work in the Wayland community we may now be backlogged on due to it, if my vague recollections are right
‎[20:24] ‎<‎Sho_‎>‎ Let's make sure it's on the 5.16 task board when we do the 5.16 kickoff
‎[20:24] ‎<‎Sho_‎>‎ which I'm guessing we'll discuss the scheduling of next Monday, and do after FOSDEM and PlaMo sprint
‎[20:26] ‎<‎Sho_‎>‎ d_ed, romangg: you got something for bshah on this? otherwise it's my turn
‎[20:26] ‎<‎Sho_‎>‎ oh, and I forgot to poke zzag, you got anything for the meeting?
‎[20:27] ‎<‎Sho_‎>‎ alright, my turn then
‎[20:28] ‎<‎Sho_‎>‎ I had an in-person eV board meeting, installed my new laptop and had some company meetings, so I didn't have that much time for Plasma
‎[20:28] ‎<‎Sho_‎>‎ I cleaned up the libtm code on master to use the new rows API in the PVD Wayland protocol and dropped the D-Bus codepath again
‎[20:28] ‎<‎Sho_‎>‎ I'm looking into some Folder View model bugs now, hoping I find the time to get fixes in before 5.15 is tagged
‎[20:28] ‎<‎Sho_‎>‎ My new laptop has a decent nVidia DGPU. I tried testing nVidia's eglstreams backend patch (D18570) just before the meeting, but kwin is crashing during the splash screen. I'll debug
‎[20:28] ‎<‎sKreamer‎>‎ Diff 18570 "EGLStream DRM Backend Initial Implementation" [Needs Review] https://phabricator.kde.org/D18570
‎[20:28] ‎<‎Sho_‎>‎ Additionally, kwin_wayland doesn't work in windowed mode on nVidia EGL due to the driver not having GL_OES_EGL_image
‎[20:29] ‎<‎Sho_‎>‎ that's it
‎[20:29] ‎<‎Sho_‎>‎ bshah: do you want to do the notes to your standards or should I?
‎[20:29] ‎<‎bshah‎>‎ feel free to.. I am swamped
‎[20:29] ‎<‎bshah‎>‎ sorry :/
‎[20:30] ‎<‎Sho_‎>‎ np
‎[20:31] ‎<‎frinring‎>‎ anyone who could be caught now who can tell what to expect from/do about using opengl in plasma widgets & wallpaper, when it comes to settings like version & Co?  :)

‎[20:38] --> Lord_of_Life (~Lord@unaffiliated/lord-of-life/x-0885362) has joined this channel.
‎[20:40] ‎<‎frinring‎>‎ darn, that silence translates into "nobody". I feel so lonely in this unknown confusing territory... time for some mantras about having a brave heart...
‎[20:44] ‎* ‎frinring‎‎ makes a plan to do some blinking demo stuff to create some attractors to this valley, so hopefully some other people will come over and help to make this an explored & lively place
‎[20:46] ‎<‎Sho_‎>‎ frinring: I didn't answer because I honestly didn't understand the question
