[17:19] <dupondje> HDMI output seems completely broken for me on Utopic :(
[17:24] <tjaalton> on what
[17:24] <tjaalton> hw
[17:24] <dupondje> Intel & Nvidia card (optimus)
[17:24] <dupondje> 01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 540M] (rev a1)
[17:24] <dupondje> 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
[17:25] <dupondje> Image of the screen http://dupondje.be/nouveau/20140923_013459.jpg
[17:25] <dupondje> I can move cursor over the screen when loggin in. But after everything is loaded, even cursor doesn't display on it anymore
[17:26] <dupondje> so really don't know where I need to start to debug
[17:29] <tjaalton> the hdmi is likely owned by the nvidia gpu
[17:29] <dupondje> It was even worse, HDMI didn't have any signal at first. But was able to track down the bug for that already (reported upstream https://bugs.freedesktop.org/show_bug.cgi?id=84203)
[17:29] <ubottu> Freedesktop bug 84203 in Driver/nouveau "[NVC1] HDMI gives no more signal since 3.15 (optimus)" [Normal,New]
[17:29] <dupondje> tjaalton: yes, HDMI is on the nvidia card
[17:29] <tjaalton> so it's just nouveau being crappy I guess
[17:30] <dupondje> well in #nouveau they tell me its prolly intel ddx that causes issues
[17:30] <tjaalton> of course
[17:31] <dupondje> ;)
[17:32] <tjaalton> try a later mainline kernel
[17:38] <dupondje> let me try :)
[17:48] <dupondje> tjaalton: same issue.
[17:48] <dupondje> also tries xorg-edgers ppa, but doesn't fix it neither
[17:49] <dupondje> tested http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ btw
[17:50] <dupondje> a quite annoying regression imo :(
[17:52] <tjaalton> regression since when
[17:53] <dupondje> worked on 14.04
[17:54] <tjaalton> well if #nouveau claims it's in the intel ddx then bisect that
[17:55] <dupondje> xserver-xorg-video-intel then? :)
[18:01] <tjaalton> yep
[18:02] <dupondje> quite annoying to bisect no? Cause it depends on some versions of xorg-server ?
[18:03] <tjaalton> build from source
[18:04] <tjaalton> trusty had 2.99.910
[18:04] <tjaalton> utopic has .914
[18:04] <tjaalton> check the versions in between
[18:16] <tjaalton> and file a bug
[20:19] <dupondje> lets bisect :D
[20:53] <dupondje> tjaalton: ok, already got it working
[20:53] <dupondje> now 7 steps to go, and we have the commit :D

[21:04] <dupondje> this one
