| RAOF | xnox: Mind if I upload a util-linux patch to fix bug #1708635 | 06:46 |
|---|---|---|
| ubot5 | bug 1708635 in util-linux (Ubuntu) "Valgrind reports " Uninitialised value was created by a stack allocation" in __uuid_generate_random" [Undecided,New] https://launchpad.net/bugs/1708635 | 06:46 |
| duflu | RAOF: So it was more random? :) | 07:07 |
| RAOF | So it didn't reference uninitialised memory when getrandom() returns ENOSYS, such as on a CI machine running a 14.04 kernel. | 07:17 |
| duflu | Oh, right. That's the Linux call and not the ANSI-C pseudorandom call guaranteed to work | 07:19 |
| alan_g | RAOF: should we land the workaround for bug 1708635 to unblock, or is a fix immanent? | 08:24 |

| RAOF | alan_g: I've uploaded a fix* | 08:29 |
| RAOF | (I've obviously not tested it in CI, but I'm confident it's a fix) | 08:30 |
| alan_g | The theory is CI should now work? | 08:31 |
| * duflu senses deja vu | 08:31 | |
| alan_g | duflu: again? | 08:32 |
| duflu | Indeed | 08:32 |
| RAOF | Oh, woops. | 08:34 |
| RAOF | Conflct with package already in proposed. | 08:35 |
| duflu | Heh. Welcome to my world (as I was discussing last week) | 08:59 |
| * alan_g muses: the other workaround would be to move CI to some builders with a recent kernel. | 09:01 | |
| ogra_ | alan_g, mind taking a look at https://forum.snapcraft.io/t/pyqt5-on-raspberry-locale-problem/1574 ? | 10:54 |
| alan_g | ogra_: ack | 10:54 |
| ogra_ | (not sure what the dbus issue there is, i helped as much as i could with the other bit) | 10:55 |
| alan_g | ogra_: the dbus bit is a mystery to me too. I can guess that it relates to the qtubuntu project, and that it's something that broke when we dropped the overlay. | 11:06 |
| ogra_ | well, i guess the demo apps still work, dont they ? perhaps you can just point him to the source for ideas | 11:07 |

| AdamH_ | Good Afternoon Gents, perhaps a daft question but is mir-kiosk supported on Ubuntu Server 16.04 or Just on Core? I want to run a Qt app in a Kiosk type setting. Have it work on a RPi but we need more horsepower so think of using a desktop class machine with Ubuntu Server | 12:30 |
| AdamH_ | Or is there a better way to do this? | 12:30 |
| ogra | the mir-kisok snap should surely also work on a classic (server) install | 12:32 |
| ogra | *-kiosk | 12:32 |
| ogra | (if not, that would be a bug i guess) | 12:33 |
| AdamH_ | ogra: Thanks I thought it should but can't get it to launch. Will keep troubleshooting in that case | 12:35 |
| ogra | file a bug if you cant get it to run ... technically it shouldnt be any different to using it on core | 12:37 |
| ogra | i.e. it should auto-start on boot | 12:37 |
| ogra | but perhaps you need some additional libs installed that are guaranteed to be there on the core images | 12:38 |
| AdamH_ | Thanks, definitely not doing that but will make sure basics are covered first. | 12:43 |
| ogra | journald (or syslog) should actually have some info ... | 12:44 |
| ogra | (a snap always uses a systemd unit to auto-start ... so there should be some errors if that fails) | 12:44 |
| AdamH_ | Thank you, as a side note how would we change the screen orientation of the mir-kiosk-apps demo to be portrait? | 13:02 |
| alan_g | AdamH_: the server image will be missing some part of the "desktop" graphics stack: mesa, mir-graphics-drivers-desktop. If they are in place it should work. | 13:03 |
| AdamH_ | alan_g: Thanks, mir-graphics-drivers-desktop is already installed, I can see it finds the driver in the syslog but can't start | 13:09 |
| alan_g | Could you pastebin the log? | 13:10 |
| AdamH_ | Yes sure http://paste.ubuntu.com/25262948/ | 13:12 |
| alan_g | Thanks. The message "Unknown command line options: --vt 1" tells us indirectly that the mesa-kms driver isn't able to initialize (but not why). | 13:17 |
| AdamH_ | Ah thanks, I did not know that. I wonder if this is to do with me running in a VM | 13:20 |
| alan_g | You installed mir-graphics-drivers-desktop from deb archive? | 13:22 |
| alan_g | Perhaps it's worth trying the miral-examples deb and running "miral-desktop -kiosk" | 13:23 |
| AdamH_ | Yes installed from deb, will try the examples and see what happens | 13:27 |
| AdamH_ | hmmm... Unable to locate package miral-examples, is this available from a ppa? | 13:29 |
| alan_g | which series are you on? | 13:31 |
| AdamH_ | I am using 16.04 | 13:31 |
| alan_g | /o\ sorry | 13:32 |
| alan_g | There's a ppa (ppa:mir-team/staging), but that also has a newer mir in it. | 13:33 |
| alan_g | I fear you're best building miral | 13:33 |
| * alan_g makes a note that a 16.04 miral ppa would be useful. | 13:35 | |
| AdamH_ | Thank you will give it a go | 13:35 |
| alan_g | take lp:miral/release | 13:35 |
| alan_g | That corresponds to the snap contents | 13:36 |
| alan_g | This should help: https://bazaar.launchpad.net/~mir-team/miral/trunk/view/head:/getting_and_using_miral.md#L131 | 13:37 |
| AdamH_ | alan_g: perfect thanks for that | 13:38 |
