alf_Saviq: greyback: Could you check which thread is using the CPU? (press 'V' in top to get a forest view with threads)13:01
Saviqfancy13:01
Saviqdoing13:01
Saviqalf_, hmm, only see a process tree, not threads with V13:03
greyback_H maybe?13:03
SaviqH13:04
Saviqyes13:04
Saviqalf_, Mir/Comp13:04
alf_Saviq: greyback_: Right V + H to also get threads13:05
greyback_yep, same here13:05
alf_Saviq: greyback_: Could you pastebin an snapshot of the top output13:06
greyback_alf_: http://pastebin.ubuntu.com/12998801/13:07
Saviqalf_, http://pastebin.ubuntu.com/12998806/13:07
alf_greyback_: Saviq: thanks13:09
alf_greyback_: Saviq: let me try on desktop to see if it's android specific or not (unless you have already tried it there?)13:10
Saviqalf_, didn't try yet, can do in 30s13:11
alf_greyback_: Saviq: Which mir/usc are you using? What's in archive at the moment?13:11
Saviqalf_, rc-proposed, so vivid overlay13:11
greyback_mir 0.1713:11
alf_Saviq: please try it if you can for more data points, I will do that also13:12
Saviqack13:12
Saviqalf_, looks android-specific indeed, couldn't reproduce here (xenial, fwiw)13:21
alf_Saviq: hmm, I can't even start a session with ubuntu-desktop-mir on wily (no overlay)13:28
Saviqalf_, not really tested, we targeted overlay for a while now...13:28
alf_Saviq: yeah, let me install that13:29
Saviqalf_, do you just get a mouse cursor?13:29
alf_Saviq: I get nothing13:29
Saviqalf_, try overlay, if that no worky, we'll see what's going on13:29
alf_Saviq: something is not right, USC log gives me Opening session x-18313:34
Saviqalf_, try a guest/different user?13:34
alf_Savig: Closing session x-183 ... and so on until it gives up13:34
alf_Saviq: ah, wait, you are talking about unity8 session, I am trying ubuntu-desktop-mir?13:35
Saviqalf_, what's that? ;)13:36
alf_Saviq: yeah, unity8-desktop-session-mir works13:36
Saviqalf_, ack :)13:36
alf_Saviq: well, kind of... if I login as normal user I get the greeter but when I login from greeter I get to the greeter again13:38
alf_Saviq: if I login as guest I just get a blank screen with mouse cursor13:38
Saviqalf_, yeah, double greeter expected13:38
Saviqalf_, guest isn't tested well, need to look into ot13:38
Saviqit13:38
alf_Saviq: right, but when I login from second greeter, I don't get into unity8, I just see the (second) greeter again13:39
Saviqalf_, oh, too many greeters...13:39
Saviqalf_, any chance you typed your pwd wrong?13:39
alf_Saviq: no, when I type it wrong, I stay in the greeter. When I type it right, I get a blank screen for a bit, then the second/unity8 greeter reloads13:41
Saviqalf_, ah, sounds like a crash13:41
Saviqalf_, that's with overlay?13:41
alf_Saviq: yes13:41
Saviqalf_, would be interested in /var/crash/ and .cache/upstart/unity8.log after you clear them and try again13:42
