Problem. Can't load (log in) with OpenGL. Loading indicator is stuck somewhere near 75% and doesn't move. Workaround: export KWIN_OPENGL_INTERFACE=egl and startkde Reproducible: Always Steps to Reproduce: 1. Find PC with Core i7 and Ubuntu 14.10 2. Start separate X session something like 'xinit /usr/bin/xterm startkde -- /etc/X11/xinit/xserverrc :1` Actual Results: Loading is stuck near 75% (indicator from breeze theme) Expected Results: Plasma appears how to get log: ➜ kde_backup cat ~/startkde #!/usr/bin/env bash set -xe startkde > log.startkde 2>&1 and xinit /usr/bin/xterm ~/startkde -- /etc/X11/xinit/xserverrc :1 My log for failed start: http://paste.in.ua/10232/ Workaround: _Groo_ from Freenode IRC channel have said that glx is broken with Intel drivers. So I have added 'export KWIN_OPENGL_INTERFACE=egl' to my 'startkde' script and I have log in successfully.
Created attachment 90271 [details] Log when I can't login (startup indicator freezes) Also can be found at http://paste.in.ua/10232/ . I'm not sure that it is helpful but I let it here.
I use kubuntu ppa if it does matter. deb http://ppa.launchpad.net/kubuntu-ppa/next/ubuntu utopic main My video card is Intel HD 4600 http://ark.intel.com/products/80807/Intel-Core-i7-4790K-Processor-8M-Cache-up-to-4_40-GHz I have seen bugs https://bugs.kde.org/show_bug.cgi?id=335983 and https://bugs.kde.org/show_bug.cgi?id=333249 but they seems not to be related to my issue.
Created attachment 90272 [details] Kwin support information when I have SUCCEEDED to login I don't know will it help but that it is . Also available in http://paste.in.ua/10233/raw/
kwin is 5.1.90
> Compositing is not active You're not compositing in the successfull login. a) can you start the compositor (Shift+Alt+F12) (and provide a new supportInformation) b) otherwise please attach the output of "glxinfo" c) does "export KWIN_USE_BUFFER_AGE=0" help? (revert the egl selection for this) d) does "export KWIN_EXPLICIT_SYNC=0" help? (revert the egl selection for this as well)
I just experienced the same problem with the latest weekly iso. a) + b) nothing interesting (cannot attach as no internet right now on the system) c) nope d) nope

I'm wondering whether 38f1945c6c437cad14e9c22929ab7947009de8e5 could be the cause.
The same to me: c) and d) doesn't help. With EGL I can press A+S-F12 but it doesn't affect anything. If I look at system settings it seems that compositing _is_ enabled. Maybe I'm looking into wrong screen... http://wstaw.org/m/2015/01/07/kde1.png

(In reply to Kakadu.hafanana from comment #10) > If I look at system settings it seems that compositing _is_ enabled. "... on startup" ;-) The setting just *tries* to start the compositor w/ kwin - this can still fail. If you uncheck this, it's not even tried (eg. because you could compose, but don't want to for whatever reason)
Managed to reproduce on a machine reverting 38f1945c6c437cad14e9c22929ab7947009de8e5 made no difference.
we're not calling bufferSwapComplete() I then put some debug into SwapEventFilter::event(xcb_generic_event_t *event), it's failing the test: if (ev->drawable == m_drawable) { if I comment this out, everything works fine and I have sexy compositing again. Obviously I don't think this is a solution, I assume this is checking that the buffer swapped was the one we're meant to be monitoring.. but it's where the issue is.
Aha, and I see why this is a new bug // Qt 5.3 doesn't forward swap events to the native event filter if (version < 0x00050400) m_haveINTELSwapEvent = false; so before we were just falling back to some other swap test method; no we're using this one, but it seems to be rubbish.
This looks fishy: if (m_haveINTELSwapEvent) { m_swapEventFilter = std::make_unique<SwapEventFilter>(window); glXSelectEvent(display(), glxWindow, GLX_BUFFER_SWAP_COMPLETE_INTEL_MASK); } we select events on glxWindow but compare the event window with window. Since the events are apparently read, could you try - m_swapEventFilter = std::make_unique<SwapEventFilter>(window); + m_swapEventFilter = std::make_unique<SwapEventFilter>(glxWindow); ?
Yeah, that does look odd, would fit my symptoms exactly. I can't test now, I need a specific machine which I don't have here, but I'll do so tomorrow morning.
Created attachment 90283 [details] glx: Fix the swap event filter for DRI3 drivers Does this patch fix the problem?
Works beautifully to me, code looks sensible too. Can we ship it?
Possibly related, my .xsession-errors is full of _xgeWireToEvent: Unknown extension 148, this should never happen. you mentioned glXWireToEvent in your patch so this seems very important?
5.2 beta is being tagged imminently so I'm going to push Frederick's change as-is so it makes it into the beta. Hope that's ok with everyone.

The latter being the case with DRI3. __glXWireToEvent() fixes this for Xlib clients by changing the field to the X drawable ID. This doesn't work for xcb clients however, so we have to expect the field to be set to either the X or the GLX drawable ID.

*** Bug 341972 has been marked as a duplicate of this bug. ***
Over the weekend I got a complaint that it still freezes on Haswell-ULT chips. As this is a quite severe issue I suggest that we disable the feature for 5.2, keep it enabled in master and stabilize it for 5.3. Due to the Qt 5.4 dependency it went into the release without any prior testing and we are currently not really able to debug and investigate issues.
(In reply to Martin Gräßlin from comment #23) > ...Due to the Qt 5.4 dependency it went into the release without any prior testing and we are > currently not really able to debug and investigate issues. Unless of course you count myself and every other KDE developer who have been using kwin with Mesa drivers and Qt 5.4 for the past several months. Did the reporter specifically say that this feature is responsible? There are numerous bug reports about freezes that have never been properly investigated, and that predate the use of swap events in kwin.
I upgraded my notebook to Qt 5.4 this morning and there I also get the freeze and it's clearly related to the feature. Disabling it unfreezes the system. Also on my main system I experienced heavy rendering errors lately, by disabling the feature all of them were instantly gone. So yes, I think this is heavily related and not sufficiently tested.

If you are able to reproduce the problem on a computer you own and have access to, then I have to say that I really don't understand what you mean by "we are currently not really able to debug and investigate issues."
that comment was written before I installed Qt 5.4 on that system.
pending issues could be related to driver (version) bugs (and actually hardware combos - i've seen an r100 notebook that did glxgears @0.5 fps - turned out it was the driver-enabled swapinterval...) given the valid concerns about the test sample size, i'd suggest to have this feature env controlled and default the env depending on the risk one is willing to take for the particular version (eg 1 for git master and 0 for releases)

[glxbackend] Introduce env variable KWIN_USE_INTEL_SWAP_EVENT The feature is pretty much untested as it depends on Qt 5.4 and this was not a requirement during the development of 5.2. On the other hand regressions in this feature are very severe as it can freeze the screen and by that render the system unusable. This change disables the feature by default.

removing release_blocker and critical as the bug is worked around. Though still needs proper fixing of course.
As a heads-up I maybe will enabling it again by default. On two systems I have, AMD and Intel, the extension is present and KWin works with the env var set fine. From how I understand it we lose quite a lot of robustness by not syncing with the X present complete notify on vblank through this extension.
Git commit e7da4d65ecbd7dea164a86aa355632ffe156e6c4 by Roman Gilg. Committed on 12/12/2019 at 00:57. Pushed by romangilg into branch 'master'. [platforms/x11/standalone] Use intel swap events by default Summary: Activate intel swap events by default if available. They were hidden behind an environmental variable because of some critical release blocking issue years ago. Manual testing indicates that there are no issues anymore with this extension. Since it allows us to use swap events with MESA drivers for optimized repaints enable swap events by default again. For now leave a modified environment variable to switch back to using no swap events easily.

This is very old and changes have been made, please confirm if this is still an issue
why it's only on glx backend, not in egl backend?
