| pochu | hey there. Every video I play is played in black&white colours, but they are full-colour. slomo told me this was X fault, since I tried running them with a different engine from mplayer and it was the same. Also, while trying to reproduce them, I've had some X crashes, one of which I reported as bug 173265 (the backtrace is completely useless). Is there something I could do to help debugging this? | 19:11 |
| ubotu | Bug 173265 on http://launchpad.net/bugs/173265 is private | 19:11 |
| pochu | This is with an intel gma 915 and the -intel driver | 19:11 |
| pochu | (hardy up-to-date) | 19:12 |
| jcristau | which xv adaptor are you using (textured or video)? | 19:13 |
| pochu | I don't really know, and I can't find on X/Debugging how to find it. | 19:21 |
| pochu | (II) Loading extension XVideo | 19:21 |
| pochu | Not sure if that means video - that's in Xorg.0.log | 19:21 |
| jcristau | mplayer allows you to choose which one | 19:21 |
| pochu | ah | 19:22 |
| jcristau | mplayer -vo xv:port=<number> | 19:23 |
| jcristau | get the number from xvinfo | 19:24 |
| pochu | mplayer -vo xv /path/to/file | 19:24 |
| pochu | ok | 19:24 |
| jcristau | (each adaptor has a "port base" line) | 19:25 |
| pochu | mplayer -vo xv:port=73 Desktop/andando10.mp4 - black&white | 19:27 |
| pochu | I only have one adaptor so the number should be the good one | 19:27 |
| jcristau | hmm, i thought only the 965 didn't have a video adaptor | 19:28 |
| pochu | 915 mobile, that is | 19:29 |
| pochu | 00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller (rev 04) | 19:29 |
| jcristau | aiui, the textured adaptor is using the 3d engine to display video, so maybe there's a bug in that part of the driver on your hardware | 19:32 |
| pochu | I've seen more bugs on lp with similar descriptions (playing a video in totem and then crash!) - bug 175303, bug 174571 | 19:34 |

| ubotu | Launchpad bug 174571 in xorg-server "Xorg crashed with SIGSEGV" [Medium,Incomplete] https://launchpad.net/bugs/174571 | 19:34 |
| pochu | dunno if they have the same hardware or not | 19:34 |
| pochu | Is it crazy to try to get the crash when running X under gdb? I've never done that before | 19:35 |
| jcristau | you need to run gdb over ssh | 19:35 |
| jcristau | but, it usually works | 19:35 |
| pochu | I could do that, yes | 19:36 |
| pochu | do you think the backtrace will be helpful? | 19:36 |
| jcristau | make sure you have debugging symbols for the server and driver | 19:36 |
| pochu | -dbg or dbgsym? | 19:36 |
| pochu | or both? :) | 19:36 |
| jcristau | either, i think | 19:37 |
| jcristau | i've never used dbgsym | 19:37 |

| jcristau | heh | 20:51 |
| jcristau | can you go to the i830_unbind_memory frame, and print the value of *mem? | 20:54 |
| pochu | I'm afraid I can't - I've restarted my laptop since I lost the connection :( | 20:55 |

| bryce | jcristau: btw, I was trying to build current xserver git-head with the current debian rules file, but it's failing in some of the glx code | 21:22 |
| bryce | jcristau: xserver compiles fine using a default ./configure, though | 21:22 |
| bryce | jcristau: I'm wondering if it's a mesa version mismatch or something? | 21:22 |
| * tormod updates DebuggingSystemCrash with links | 21:26 | |
| pochu_ | any idea? :) | 21:41 |
| tormod | I don't know what bus_addr is, but that's a seriously big number :) | 21:47 |
| pochu_ | heh | 21:47 |
| pochu_ | I have 1GB of ram, fwiw | 21:47 |
| tormod | pochu_: did you follow DebuggingXorg? Was it clear? Just would like feedback since I wrote it. Any suggestions are welcome. | 21:49 |
| pochu_ | yeah, I did, and it looks perfect :) | 21:49 |
| tormod | well that's what I wanted to hear :) | 21:49 |
| pochu_ | although you might want to say in the part of restarting X after modifying xorg.conf that it's a good idea to do it over ssh, since you have to connect to ssh anyway | 21:50 |
| pochu_ | since ctrl+alt+f1 corrupted my screen and I had to reboot to restart it ;) | 21:50 |
| Q-FUNK | bryce: there's been progress on the -amd driver. it appears that changes in VBE since X core 1.3 might make -amd and several other marginal drivers (such as the siliconmotion on my laptop, also) fail DDC parsing. | 21:53 |
| tormod | pochu_: if ctrl-alt-f1 corrupts your screen that's another problem, but it's a good idea to suggest doing it remotely, thanks. | 21:54 |
| * pochu_ looks at fdo to see if this has been reported there | 21:59 | |
| pochu_ | doesn't look like | 22:05 |
| jcristau | bryce: xserver master needs mesa master | 22:18 |
| jcristau | pochu_: it's crashing because mem->name is NULL... | 22:19 |
| jcristau | but, the mprotect() call just before that shouldn't have failed, i think | 22:20 |
| jcristau | anyway, it'd be good to report the crash upstream | 22:20 |
| pochu_ | any X expert wants to do that? I'm afraid a developer will ask something I won't know how to answer ;) | 22:22 |
| jcristau | don't worry about that, there will be people to help :) | 22:24 |
| pochu_ | :-) | 22:24 |
| jcristau | weird, your two backtraces on #173265 are different | 22:25 |
| pochu_ | the first one looks a bit similar since frame 8 though | 22:27 |
| pochu_ | although mem isn't null in that one | 22:27 |
| jcristau | not the same line number | 22:27 |
| pochu_ | oh, right | 22:27 |
| pochu_ | Do you want me to get a third one? ;-) | 22:28 |
| jcristau | heh | 22:29 |
| pochu_ | not kidding :P | 22:30 |
| pochu_ | are they two different bugs, or could they be the same one? | 22:30 |
| jcristau | i don't know | 22:31 |
