| duflu | robert_ancell: Hey just FYI, that scrolling speed problem with Xmir, while it has a fix may not get Fix Released as quickly as Xmir itself. We might end up with more people seeing the problem for a while till the next Unity8 update | 03:57 |
|---|---|---|
| robert_ancell | duflu, is that going to affect the SRU to Xenial? | 03:58 |
| duflu | robert_ancell: Yes, probably. But only for users of X apps in Unity8 on xenial. I'm not sure that's a major audience | 03:59 |
| robert_ancell | duflu, probably not | 03:59 |
| duflu | I'm just warning everyone so they expect the duplicate bug reports when they happen | 04:00 |
| duflu | It is however a bug that already has a fix | 04:00 |

| greyback | alan_g: it used to silence compiler warnings due to the UAL header files | 10:55 |
| greyback | which made compilation with -Werror fail | 10:56 |
| greyback | that situation may have been fixed now | 10:56 |

| aquarius_ | Phone question: how can I launch an application on the phone if Unity 8 isn't running? | 14:17 |
| aquarius_ | Unity 8 does some jiggery-pokery with setting up its own mir sockets and so on, as far as I can tell... | 14:17 |
| alan_g | aquarius_: what are you using as a shell if you're not using U8? | 14:20 |
| aquarius_ | alan_g: at the moment, assume nothing and that I'm launching apps from the command line. (I'm exploring the idea of a different shell, but the first part is to have some way I can launch apps at all without unity around :)) | 14:21 |
| alan_g | well, if you mean phone apps (not command line programs) they need a shell/mir server to talk to | 14:22 |
| alan_g | It would be like launching an X app without an X server | 14:23 |
| alan_g | Doomed | 14:23 |
| aquarius_ | ya, graphical apps -- qml, whathaveyou. So, question: an app can't launch and talk to mir itself? That's not how Mir works, I take it; something needs to be the "display server", and that's Unity 8? | 14:23 |
| anpok | you can launch unity-system-compositor | 14:23 |
| aquarius_ | so if I don't have unity running, I need to write a separate "dummy window manager" to act as a shell? | 14:23 |
| anpok | or you might have it still running.. | 14:23 |
| alan_g | U8 is the Mir server | 14:24 |
| aquarius_ | ah! unity-system-compositor is an alternative mir server? | 14:24 |
| anpok | u-s-c owns the screen and unity8 connects as a fullscreen client to it | 14:24 |
| alan_g | aquarius_: you might find lp:miral a good starting point for an alternative server | 14:25 |
| anpok | but in general it seems that you should write an alternative server | 14:25 |
| anpok | u-s-c could serve as an intermediate replacement but it only accepts full screen clients | 14:25 |
| alan_g | But IIUC you can find what you need in the "running the software" bit of this: http://www.octopull.co.uk/sw-dev/WorkingOnAPhone.html | 14:26 |
| aquarius_ | full screen clients are fine for my use case (which is very simple at the moment! It might get more complex later, but i'm just exploring) | 14:26 |
| anpok | so you are better of launching miral-shell from lp:miral as a client to u-s-c or as a u-s-c replacement. | 14:26 |
| aquarius_ | so, if I have u-s-c running, I should be able to launch (for example) qmlscene and it should work? | 14:27 |
| alan_g | No | 14:27 |
| aquarius_ | ah, so I still need miral-shell or similar running as well? | 14:28 |
| alan_g | USC is very fussy about what connects to it. | 14:28 |
| alan_g | aquarius_: have a skim through the above article - you don't need to build things, but it also covers getting control of the screen | 14:29 |
| aquarius_ | am indeed reading it as we speak :) | 14:29 |
| ogra_ | wasnt there a tiling WM demo in the mir code somewhere ? | 14:29 |
| ogra_ | you might be able to spawn that and run your app in it | 14:29 |
| alan_g | ogra_: there is, there's also a non tiling one. (But the one in MirAL is a better starting point) | 14:31 |
| aquarius_ | alan_g: that demo isn't on the phone already, I imagine? | 14:37 |
| aquarius_ | Certainly I'll take a look at miral, which seems like the right thing to do | 14:37 |
| aquarius_ | I've just gotta set up a build environment and whatnot to play around with that :) | 14:37 |
| alan_g | aquarius_: is isn't installed by default. But if you've e.g. a chroot set up you can install it | 14:38 |
| aquarius_ | kk | 14:38 |
| aquarius_ | that makes sense | 14:38 |
| aquarius_ | I was just sneaily hoping to avoid work ;) | 14:38 |
| alan_g | Or if you've made thing RW you can just use apt | 14:38 |
| * alan_g doesn't recommend doing that though | 14:39 | |
| aquarius_ | yeah. As it happens I have made this RW so I can experiment with things, but I don't really want to install loads of mad stuff and break the system images just yet | 14:39 |
| alan_g | aquarius_: in that case installing mir-demos shouldn't do much harm. And gives you example servers and apps to play with | 14:41 |
| aquarius_ | oh really? that sounds useful | 14:44 |
| alan_g | $ mir_demo_server --test-client mir_demo_client_egltriangle | 14:44 |
| alan_g | But to get serious set up a chroot | 14:46 |
| aquarius_ | certainly I will do when I get serious :) | 14:46 |
| ogra_ | when will *that* ever happen ? | 14:46 |
| aquarius_ | ha! shush, ogra ;) | 14:47 |
| ogra_ | :) | 14:47 |
| alan_g | when the first phone bricks | 14:47 |
| aquarius_ | hm, mir-demos isn't available in the repos. do I need to have a different archive enabled? | 14:47 |
| aquarius_ | the phone points at vivid stuff | 14:47 |
| alan_g | oh, I guess that's in universe | 14:48 |
| aquarius_ | it is. bah :) | 14:48 |
| aquarius_ | and vivid stuff isn't available in the archives any more. Can I use the wily version, or does it change in lockstep with newer mir? | 14:49 |
| aquarius_ | huh. libmirclient9 on the phone is the version from yakkety. So mir stuff is more up to date than it pointing at "vivid" archives would imply :) | 14:50 |
| anpok | vivid stuff is in the stable-phone-overlay ppa | 14:51 |
| anpok | and xenial stuff too.. | 14:51 |
| aquarius_ | huh, darn. mir-demos 0.21 and 0.23 will both not install for dependency reasons | 14:53 |
| aquarius_ | I bet I have to be running rc-proposed on the phone to match the version of mir-demos in yakkety. | 14:58 |
| alan_g | Don't mix with yakkety - the gcc isn't compatible | 14:59 |
| alan_g | Add "universe" in /etc/apt/sources.list, apt update && apt-install mir-demos | 14:59 |
| alan_g | Or is that too serious? | 15:00 |
| aquarius_ | I already have that, though | 15:00 |
| aquarius_ | deb http://ports.ubuntu.com/ubuntu-ports/ vivid universe | 15:00 |
| alan_g | Shouldn't that be deb http://ports.ubuntu.com/ubuntu-ports vivid main universe | 15:00 |
| aquarius_ | deb http://ports.ubuntu.com/ubuntu-ports/ vivid-updates main restricted is in there too | 15:01 |
| * alan_g is out of suggestions | 15:02 | |
| aquarius_ | I suspect this is because mir-demos *was* in vivid universe, but vivid is out of support now :) | 15:03 |
| aquarius_ | (checks packages.gz file) | 15:04 |
| aquarius_ | hey! it's there. | 15:04 |
| aquarius_ | mir-demos, 0.12.1+15.04.20150324-0ubuntu1 | 15:04 |
| aquarius_ | but apt-cache search doesn't find it. That's weird. | 15:05 |
| alan_g | It ought to be in the stable-phone-overlay ppa | 15:05 |
| alan_g | Probably 0.23 | 15:05 |
| aquarius_ | hm, have I ever actually run apt update on this device? | 15:06 |
| alan_g | that would help | 15:07 |
| aquarius_ | it would rather, wouldn't it :) | 15:07 |
| aquarius_ | and there it is. Good one, Langridge, you moron | 15:08 |
| aquarius_ | installed :) | 15:08 |
| aquarius_ | ERROR: Dynamic exception type: St12system_error | 15:09 |

| alan_g | aquarius_: that's familiar (a bug - IIRC there's an LD_PRELOAD workaround) | 15:13 |
| alan_g | not that bug | 15:13 |
| aquarius_ | the bug sorta suggests that i need a mir-graphics-drivers package installed, but I have mir-graphics-drivers-android | 15:13 |

| aquarius_ | woo, spinning triangle :) | 15:14 |
| aquarius_ | very very flickery spinning triangle. | 15:15 |
| alan_g | You "forgot" $ sudo stop lightdm | 15:15 |
| aquarius_ | ah, because unity-system-compositor is still running. I don't want that, right? | 15:15 |
| alan_g | they fight | 15:16 |
| aquarius_ | if I stop lightdm entirely, then the screen goes black | 15:16 |
| aquarius_ | and running egltriangle doesn't show anything on screen | 15:16 |
| alan_g | mirbacklight | 15:17 |
| aquarius_ | ah, as per the doc | 15:17 |
| aquarius_ | I did forget that this time :) | 15:17 |
| aquarius_ | winner! | 15:17 |
| aquarius_ | that works. | 15:17 |
| alan_g | :) | 15:18 |
| aquarius_ | brill. Now to convince qmlscene to start up :) | 15:18 |
| aquarius_ | (thank you, alan_g, this is really helpful, btw!) | 15:19 |
| alan_g | yw | 15:19 |
| aquarius_ | so the mir_demo_server is enough to run mir-understanding clients on top, excellent; is there a layer wich goes in between a "normal" app (say, qmlscene, or a compiled Qt app) and mir-demo-server, or does Qt know how to talk to Mir itself? | 15:21 |
| anpok | aquarius_: QT_QPA_PLATFORM=ubuntumirclient needs to be set | 15:21 |
| anpok | and the user needs to have read write access rights on the MIR_SOCKET opened by the server.. | 15:22 |
| alan_g | Or more generally: https://bazaar.launchpad.net/~mir-team/miral/trunk/view/head:/miral-shell/miral-run.sh | 15:22 |
| anpok | or use the --launch-client <clientbinary> functionality of the various servers.. to avoid having a socket file | 15:22 |
| aquarius_ | I'm using --test-client | 15:23 |
| alan_g | True. --launch-client also deals with the environment variables | 15:24 |
| anpok | then qmlscene still needs QT_QPA_PLATFORM | 15:24 |
| anpok | oh does it now? | 15:24 |
| anpok | ok | 15:24 |
| alan_g | That got added in 0.22 | 15:25 |
| aquarius_ | progress! | 15:26 |
| aquarius_ | LD_PRELOAD=libpthread.so.0 mir_demo_server --launch-client simp.sh, where simp.sh is QT_QPA_PLATFORM=ubuntumirclient qmlscene /opt/click.ubuntu.com/org.kryogenix.fontbrowser/current/main.qml , gives me a tiny mouse pointer in the top left of the screen :) | 15:27 |
| aquarius_ | ah. org.freedesktop.DBus.Error.NoServer: Failed to connect to socket /tmp/dbus-DTpyAMgnHQ: Connection refused | 15:28 |
| aquarius_ | and indeed there is no dbus socket there | 15:29 |
| aquarius_ | although $DBUS_SESSION_BUS_ADDRESS is set. Interesting. | 15:29 |
| alan_g | Prefix with dbus-run-session? | 15:30 |
| aquarius_ | ha haaaaaa! | 15:31 |
| alan_g | Or, maybe, go for an app that doesn't use dbus? | 15:31 |
| aquarius_ | and I have an app running! with no unity 8 at all! score. :) | 15:31 |
| aquarius_ | brilliant. | 15:31 |
| aquarius_ | thank you very much alan_g and anpok | 15:32 |
| aquarius_ | it does still have a tiny mouse pointer :) | 15:33 |
| anpok | and you dont want that? | 15:33 |
| aquarius_ | nope. this is on the phone | 15:33 |
| alan_g | aquarius_: tough. This is an *example* of how to use the mir library, not a fully function mir server. | 15:35 |
| * aquarius_ laughs | 15:35 | |
| aquarius_ | it wasn't a complaint | 15:35 |
| aquarius_ | I have gone from zero to demonstrable in about fifteen minutes with your help, which was exactly what I wanted. Doing this properly needs more than just wiring together existing demos | 15:35 |
| aquarius_ | hence I shall look into miral and so on! | 15:36 |
| alan_g | Good luck | 15:37 |
| aquarius_ | really helpful. Thank you, people. | 15:37 |
| alan_g | anpok: that make me think MirAL ought to have a way to detect pointing devices and a way to disable the cursor. | 15:41 |
| anpok | yes | 15:41 |
