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] Bug 173265 on http://launchpad.net/bugs/173265 is private [19:11] This is with an intel gma 915 and the -intel driver [19:12] (hardy up-to-date) [19:13] which xv adaptor are you using (textured or video)? [19:21] I don't really know, and I can't find on X/Debugging how to find it. [19:21] (II) Loading extension XVideo [19:21] Not sure if that means video - that's in Xorg.0.log [19:21] mplayer allows you to choose which one [19:22] ah [19:23] mplayer -vo xv:port= [19:24] get the number from xvinfo [19:24] mplayer -vo xv /path/to/file [19:24] ok [19:25] (each adaptor has a "port base" line) [19:27] mplayer -vo xv:port=73 Desktop/andando10.mp4 - black&white [19:27] I only have one adaptor so the number should be the good one [19:28] hmm, i thought only the 965 didn't have a video adaptor [19:29] 915 mobile, that is [19:29] 00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller (rev 04) [19:32] 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 [19:34] I've seen more bugs on lp with similar descriptions (playing a video in totem and then crash!) - bug 175303, bug 174571 [19:34] Bug 175303 on http://launchpad.net/bugs/175303 is private [19:34] Launchpad bug 174571 in xorg-server "Xorg crashed with SIGSEGV" [Medium,Incomplete] https://launchpad.net/bugs/174571 [19:34] dunno if they have the same hardware or not [19:35] Is it crazy to try to get the crash when running X under gdb? I've never done that before [19:35] you need to run gdb over ssh [19:35] but, it usually works [19:36] I could do that, yes [19:36] do you think the backtrace will be helpful? [19:36] make sure you have debugging symbols for the server and driver [19:36] -dbg or dbgsym? [19:36] or both? :) [19:37] either, i think [19:37] i've never used dbgsym === emilio is now known as pochu_ [20:01] let's get started :-) [20:08] I'd have expected https://help.ubuntu.com/community/DebuggingSystemCrash to explain how to run X under gdb :-/ [20:09] https://wiki.ubuntu.com/DebuggingXorg explains how to attach to it though :-) [20:14] ouch, ctrl+alt+f1 corrupted the screen [20:14] hmm, I could have restarted X through ssh instead of a tty...

Was it clear? Just would like feedback since I wrote it. Any suggestions are welcome. [21:49] yeah, I did, and it looks perfect :) [21:49] well that's what I wanted to hear :) [21:50] 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] since ctrl+alt+f1 corrupted my screen and I had to reboot to restart it ;) [21:53] 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. [21:54] pochu_: if ctrl-alt-f1 corrupts your screen that's another problem, but it's a good idea to suggest doing it remotely, thanks. [21:59] * pochu_ looks at fdo to see if this has been reported there [22:05] doesn't look like [22:18] bryce: xserver master needs mesa master [22:19] pochu_: it's crashing because mem->name is NULL... [22:20] but, the mprotect() call just before that shouldn't have failed, i think [22:20] anyway, it'd be good to report the crash upstream [22:22] any X expert wants to do that?
