| dupondje | HDMI output seems completely broken for me on Utopic :( | 17:19 |
|---|---|---|
| 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) | 17:24 |
| 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 | 17:25 |
| dupondje | so really don't know where I need to start to debug | 17:26 |
| 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 | 17:29 |
| dupondje | well in #nouveau they tell me its prolly intel ddx that causes issues | 17:30 |
| tjaalton | of course | 17:30 |
| dupondje | ;) | 17:31 |
| tjaalton | try a later mainline kernel | 17:32 |
| dupondje | let me try :) | 17:38 |
| dupondje | tjaalton: same issue. | 17:48 |
| dupondje | also tries xorg-edgers ppa, but doesn't fix it neither | 17:48 |
| dupondje | tested http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ btw | 17:49 |
| dupondje | a quite annoying regression imo :( | 17:50 |
| tjaalton | regression since when | 17:52 |
| dupondje | worked on 14.04 | 17:53 |
| tjaalton | well if #nouveau claims it's in the intel ddx then bisect that | 17:54 |
| dupondje | xserver-xorg-video-intel then? :) | 17:55 |
| tjaalton | yep | 18:01 |
| dupondje | quite annoying to bisect no? Cause it depends on some versions of xorg-server ? | 18:02 |
| tjaalton | build from source | 18:03 |
| tjaalton | trusty had 2.99.910 | 18:04 |
| tjaalton | utopic has .914 | 18:04 |
| tjaalton | check the versions in between | 18:04 |
| tjaalton | and file a bug | 18:16 |
| dupondje | lets bisect :D | 20:19 |
| dupondje | tjaalton: ok, already got it working | 20:53 |
| dupondje | now 7 steps to go, and we have the commit :D | 20:53 |

| dupondje | this one | 21:04 |
| tjaalton | let ickle know | 21:08 |
