[03:11] <robert_ancell> This is on zesty
[14:02] <kgunn> hey guys so i was chatting with dslul in #snappy, he was trying out the mir-kiosk stuff
[14:03] <kgunn> oops...and having network issues too i guess
[14:03] <kgunn> will wait
[14:03] <kgunn> so it fails on the mir-kiosk (server) bringup part

[14:04] <kgunn> Dec  9 11:19:58 localhost snap[1909]: Mir fatal error: Failed to get frontbuffer
[14:04] <kgunn> but it looks like it's finding the kms/drm drivers fine...
[14:04] <kgunn> any ideas?
[14:05] <kgunn> alan_g: camako ^
[14:05] <dslul> kgunn, what does this mean: pci id for fd 7: 1013:00b8, driver (null)
[14:06] <dslul> it is just before the error, and after selecting the driver
[14:06] <kgunn> no idea :)
[14:07] <kgunn> but maybe one of these guys will
[14:07] <kgunn> oh... anpok_ is on... ^^
[14:11] <dslul> I've just installed the overlay, let's see what happens
[14:16] <alan_g> kgunn: well, the "Failed to get frontbuffer" error comes from the kms driver: it's failing to get a buffer for compositing to. But that doesn't tell us why
[14:21] <daniele_> kgunn, I did what you said, added the ppa, then sudo apt update and dist-upgrade, rebooted but lightdm doesn't have the unity8 entry
[14:22] <kgunn> daniele_: right...you have to do one more step, sudo apt-get install unity8-desktop-session-mir
[14:22] <kgunn> then you should prolly reboot
[14:23] <daniele_> unity8-desktop-session-mir : Depends on: unity8-desktop-session (>= 1.0.13) but is not going to be installed
[14:23] <daniele_> I think something went wrong
[14:23] <anpok_> what driver is that?
[14:25] <anpok_> ah qemu
[14:25] <anpok_> switch model from VGA to QXL
[14:26] <daniele_> in virt-manager?
[14:26] <anpok_> yes
[14:27] <daniele_> I can't find this option
[14:29] <anpok_> hm there should be a video section .. in which you can switch the model
[14:30] <kgunn> daniele_: click the little information icon....
[14:30] <kgunn> i think it brings up a panel with all those options...then you can click on video/gfx
[14:30] <daniele_> ok found it
[14:30] <daniele_> it was set to cirrus
[14:31] <daniele_> it works now!
[14:32] <daniele_> thank you
[15:04] <kgunn> daniele_: great! if you have more questions let us know....
[15:04] <kgunn> would love to hear if you have a specific application you're chasing
[15:16] <camako> kgunn, I am not sure if you've gotten to the bottom of dslul's problem, but the "pci id for fd 7: 1013:00b8, driver (null)" is coming from the Mesa driver.
[15:17] <camako> It's not finding the correct dri backend
[15:19] <camako> It's not related to Mir, but rather the setup... I think it has to do with mixing a new Mesa with an old(er) distro... Like Mesa 13.0.x vs Xenial...
[15:22] <daniele_> camako, I have mesa 12, we already solved the problem, it was a misconfiguration in virt-manager
[15:23] <daniele_> kgunn, nothing serious for now, but I worked in IoT and wanted to hack some code in case I needed it in the future
[15:25] <kgunn> glad we solved that too...i'll know if someone else asks
[15:28] <daniele_> maybe you can write it in the tutorial https://developer.ubuntu.com/en/snappy/guides/mir-snaps/
[15:29] <daniele_> btw, it would be great to have support for raspberry pi 2/3, since they are pretty common and cheap
