[11:41] <Walther_> Hello folks! Just did do-release-upgrade -d to saucy and followed isntall instructions on how to install Mir. However, now I'm getting no "unity" - no top bar, no sidebar, but desktop shows and i can fire up terminals via ctrl-alt-t and so forth
[11:41] <Walther_> Also, the display is running in pretty low res
[11:42] <Walther> on the suggested "sudo mir_demo_server", i get the following, pehaps hinting at problems:
[11:42] <Walther> ERROR: /build/buildd/mir-0.0.6bzr848saucy0/src/server/graphics/gbm/gbm_display_helpers.cpp(284): Throw in function int mir::graphics::gbm::helpers::DRMHelper::open_drm_device(const mir::graphics::gbm::helpers::UdevHelper&)
[11:42] <Walther> Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> >
[11:42] <Walther> std::exception::what: Error opening DRM device
[11:42] <Walther> [boost::errinfo_errno_*] = -13, "Unknown error -13"
[11:43] <Walther> Help very much appreciated!
[11:52] <Walther> Also, walther@doppio:~$ grep -i xmir /var/log/Xorg.0.log
[11:52] <Walther> [     8.668] xorg-server 2:1.14.1-0ubuntu0.8+xmir1 (For technical support please see http://www.ubuntu.com/support)
[11:52] <Walther> [     8.678] (WW) "xmir" is not to be loaded by default. Skipping.
[11:57] <mlankhorst> Walther: hybrid, by any chance?
[11:57] <Walther> Nope, pure 7970 only desktop
[11:57] <Walther> core2quad -> no integrated graphics
[11:58] <mlankhorst> is the dri node in use by any chance? lsof /dev/dri/*
[11:58] <Walther> Will have a haswell w/ igpu soon when my new parts arrive, but that's another matter
[11:58] <Walther> mlankhorst: empty
[11:58] <Walther> er, empty response, that is
[11:59] <Walther> I'm pretty sure i'm not getting mir at all, from Xorg.0.log [     8.678] (WW) "xmir" is not to be loaded by default. Skipping.
[11:59] <Walther> also the ps aux grep compositor thingy returns nothing but the grep command itself
[12:01] <Walther> Not afraid of cli/techy stuff, if you have any ideas on where to look / what to try, just mention
[12:02] <Walther> /etc/lightdm/lightdm.conf.d/10-unity-system-compositor.conf has the appropriate lines
[12:06] <Walther> mlankhorst: further ideas, by any chance?
[12:15] <mlankhorst> not atm, is that southern islands? :P
[12:16] <mlankhorst> and does it work with normal X?
[12:17] <Walther> Tahiti, and worked fine on 13.04
[12:18] <Walther> w/ fglrx at least
[12:18] <Walther> but logging in with this 13.10 + mir install -> a desktop without bars/dash and low res
[12:22] <Walther> Hm, apparently by launching gnome-control-center I could adjust the screen res to right. But I think I'm not running mir, and yeah, unity/dash are mising
[12:23] <Walther> Ha, dconf reset -f /org/compiz did the trick
[12:23] <Walther> of getting bars back.
[12:23] <Walther> Still not sure I'm having mir though.
[12:26] <Walther> ...yeah, still getting [     9.099] (WW) "xmir" is not to be loaded by default. Skipping.
[12:26] <mlankhorst> fglrx won't work with mir
[12:26] <Walther> Also, graphics rendering is slow - moving windows around, typing text, etc
[12:26] <Walther> mlankhorst: Yeah, I removed proprietary drivers as per instructions
[12:26] <Walther> on the foss drivers atm afaik
[12:27] <mlankhorst> yeah you have a southern islands chip, most support is in saucy atm except for the ddx :P
[12:27] <Walther> I am running saucy :)
[12:27] <mlankhorst> so you'd need to recompile xserver-xorg-video-ati yourself with glamor enabled for it to work
[12:29] <Walther> but yeah, i'm running saucy, so you said the support should be there
[12:29] <mlankhorst> most support, but you need all support..
[12:29] <Walther> Ah
[12:30] <Walther> hmm, i wonder if xorg-edgers would help
[12:30] <Walther> Or would that just completely break all chances of mir workigng?
[12:30] <Walther> -g
[12:32] <mlankhorst>  if you want mir on that card you need to build glamor support in the xserver-xorg-video-ati source of the mir ppa
[12:33] <Walther> hnggh, are you absolutely sure that's the only option for now?
[12:34] <Walther> i can't find any documentation on the matter
[12:34] <Walther> (of course at early testing / development phases there *isn't* often documentation...)
[12:35]  * mlankhorst points at the 'need'
[12:35] <Walther> Sigh... Well, thanks for help!
[12:35] <Walther> I'll probably purge the mir repo and revert back to "just" 13.10 then, and see how / when things progress
[12:36] <Walther> Should I file a bug or something on Tahiti / Southern island support?
[12:36] <Walther> (and mir compatibility, that is)
[12:40] <mlankhorst> it's the same as normal xorg-server in this case, if normal xorg-server works, mir-ified xserver would probably work too
[12:47] <arsson> u-s-c nouveau support? When...?
[13:12] <mlankhorst> dno, wrote it ages ago
