| furkan | tjaalton: the new radeon TearFree feature fixes my problem | 19:05 |
|---|---|---|
| tjaalton | furkan: guess it just hides the problem then | 19:31 |
| boax | hello | 22:52 |
| boax | there is a critical bug in ubuntu 15.04! | 22:52 |
| boax | i am talking in #ubuntu-devel and in #xorg-devel | 22:52 |
| boax | in two days there should be the release of 15.04 and its fully unusable on some machines! | 22:53 |
| boax | how to reproduce: dd the most recent daily build into an usb pendrive, boot from it, open libreoffice -> there is an Xorg server crash | 22:53 |
| boax | http://pastebin.com/9K0W1NwU | 22:54 |
| boax | this report here looks same: https://bbs.archlinux.org/viewtopic.php?id=195666 | 22:55 |
| RAOF | boax: Is there an Ubuntu bug filed? | 23:23 |
| boax | RAOF: i was able to face that all down | 23:24 |
| boax | http://pastebin.com/9K0W1NwU | 23:24 |
| boax | is related to an gnome 3.14 bug | 23:24 |
| RAOF | boax: You should have got a prompt to submit an error report to Launchpad? | 23:25 |
| boax | RAOF: check the last message here: https://bbs.archlinux.org/viewtopic.php?id=194819 | 23:25 |
| boax | the bug is somewhat strange. it come on few machines but on those machines it always come | 23:25 |
| boax | and makes those machines somewhat unusable | 23:25 |
| RAOF | Sure. | 23:26 |
| RAOF | Have you filed a bug on launchpad? | 23:26 |
| RAOF | Have you got a ‘submit error’ popup? | 23:26 |
| boax | i cant beleive that i am the only one with that bug | 23:26 |
| boax | or are there only that few people who test upcomming versions like 15.04? | 23:26 |
| RAOF | Because if you submit the bug that way, it'll come attached with all sorts of useful debugging information. | 23:26 |
| boax | the solution for the bug seem to be: backport some things from recent gnome versions that fix that error or bump the version of gnome to the recent one that dont cause this error | 23:27 |
| RAOF | Neither of those is the solution to an X server crash. | 23:28 |
| RAOF | At best, that's a workaround. | 23:28 |
| RAOF | If you submit the bug report to Launchpad we'll get a full backtrace, with symbols, and it'll be much more likely that we can fix it. | 23:28 |
| boax | RAOF: you are a dev that could help when reported the way you explain here? | 23:31 |
| RAOF | Yes. | 23:31 |
| boax | okay. to help you providing the information you need i have to start the system that crashes, let it crash and then when it ask me if it should send the crash report have to answer yes? | 23:33 |
| boax | how can that be done on an machine that does not have an internet connection? | 23:33 |
| RAOF | Hah. That's a little more difficult, but not too much. | 23:33 |
| boax | i have an usb pendrive that can travel the data from the one to the other machine | 23:34 |
| RAOF | When the machine crashes it should generate a /var/crash/_usr_bin_X_something_or_other.crash file. | 23:34 |
| boax | okay. i get that for you :) | 23:35 |
| RAOF | On a machine with an internet connection you can then run “ubuntu-bug that_crash_file”, and it'll do the reporting bits. | 23:36 |
| boax | RAOF: okay. i have the file after making it 777 to be able to copy it to the usb pendrive as a normal user. its about 5mb. the machine i have internet on is not ubuntu. should i upload the file to you? | 23:39 |
| RAOF | Ok; if you can put it somewhere I can download it. | 23:40 |
| boax | uploading... have you already an idea on what part the bug could be? Xorg server? | 23:41 |
| RAOF | If the X server's crashing it's an X bug. | 23:44 |
| RAOF | (Almost certainly) | 23:44 |
| boax | you got the file? Check your query ;) | 23:45 |
| RAOF | Yup. | 23:46 |
| RAOF | You've hit https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1443456 | 23:46 |
| ubottu | Launchpad bug 1443456 in xorg-server (Ubuntu) "Xorg crashed with SIGABRT in fbBltOne()" [Medium,New] | 23:46 |
| boax | i told tarpman that he was right with guessting that this could be the error :) | 23:50 |
| boax | can i help somehow to debug that error? | 23:50 |
| boax | i think its more then "Medium". Its critical or blocking | 23:50 |
| boax | RAOF: can i do something else to help you debugging this error? | 23:54 |
| RAOF | No, it seems pretty obvious what the immediate problem is; glamor shouldn't be passing in a NULL destination to fbCopy. | 23:55 |
| RAOF | This doesn't look like something that should block the release, but should be fixed in an early update. | 23:59 |
