[Pieter De Wit (pieter-insync)]

This is an upgrade from 11.10 to 12.04 beta.

[Bryce Harrington (bryce)]

Should be fixed in xserver-xorg-input-evdev 1:2.6.99.901+git20120126-0ubuntu3

[Pieter De Wit (pieter-insync)]

Thanks Bryce, where can I grab the package from ?

[Bryce Harrington (bryce)]

It's in the archive, so unless you have a slow mirror or something, just update normally.

[Pieter De Wit (pieter-insync)]

Hhhhmmmm - I will vote for the slow mirror - still nothing :(

I will search for the package on the main mirror.

Thanks anyways !

If worse comes to worse you can also download the .debs directly from
launchpad. But it should be coming through soon I hope!

[Pieter De Wit (pieter-insync)]

I have been looking at https://launchpad.net/ubuntu/precise/+source/xserver-xorg-input-evdev/+builds?build_state=all and I don't see a new build for it ? I also can't find it on LP, mind giving me a link ?

Thanks !

[Bryce Harrington (bryce)]

Hi Pieter, sorry the fix I was thinking of was in xserver-xorg-input-synaptics 1.5.99~git20120220-0ubuntu3

If that doesn't solve this evdev issue, please collect a full backtrace on this crash - see http://wiki.ubuntu.com/X/Backtracing for guidance.

[Pieter De Wit (pieter-insync)]

Hi Bryce,

Does xserver-xorg-input-synaptics provide evdev support ?

The problem is removing evdev will also remove:

mythbuntu-desktop xorg xserver-xorg xserver-xorg-input-all xserver-xorg-input-evdev

xserver-xorg-input-synaptics is already installed

[Pieter De Wit (pieter-insync)]

Some more comments to add :)

If I comment out the Device and event_key_remap section from the config the module loads. Perhaps something has changed upstream ?

[Pieter De Wit (pieter-insync)]

"Asked" upstream:

https://bugs.freedesktop.org/show_bug.cgi?id=46588

[Bryce Harrington (bryce)]

There's been some changes in Ubuntu's xserver recently for input device handling. (That's where the massive idiocy on my part about the -synaptics stuff earlier came from). That bug led to crashes when input devices were enabled/disabled and synaptics was in use, so I assumed that's all that was going on. However, that bug's fixed, and plus you're not using synaptics.

Thanks for collecting the more detailed backtrace. When you get a chance please also attach your full /etc/X11/xorg.conf and /var/log/Xorg.0.log. The output of `xinput list` might also be relevant.

The code is crashing in VAuditF, with this code:

VAuditF(const char *f, va_list args)
    ...
    len = vsnprintf(buf, sizeof(buf), f, args);

According to your trace, the f parameter being passed in is invalid:

#4 VAuditF (f=0xb <Address 0xb out of bounds>, args=0xb72e1318 "Segmentation fault") at ../../os/log.c:517

0xb certainly doesn't look like a valid pointer. It is curious what call #5 was. Maybe try installing xserver-xorg-input-evdev-dev?

More troubling is that the thing it was trying to print out is "Segmentation fault", which means this crash is occurring while trying to handle another crash, so the real problem is hidden.

[Bryce Harrington (bryce)]

What version xserver are you running? Might try updating it to get the most recent fixes (which pertain to input device detection)

[Pieter De Wit (pieter-insync)]

And strace ! :D

[Bryce Harrington (bryce)]

Aha bingo, I've repo'd the bug on my own hardware.

[Pieter De Wit (pieter-insync)]

Awesome - step in the right direction :)

[Pieter De Wit (pieter-insync)]

Since we are patching.... :)

Change line 1064 to :

#ifdef MULTITOUCH
    int i;
#endif

To avoid compiler warning about unused var i

[Pieter De Wit (pieter-insync)]

And comment out line 1349, after the above "patch" :)

[Pieter De Wit (pieter-insync)]

I am guessing that this will cripple the 12.04 release for people with funky mice and almost all Mythbuntu users ?

[Pieter De Wit (pieter-insync)]

Right - so after a few updates I decided to try this again. I now get the nvidia logo, then X dies with this message:

It looks the same (to me) as the previous erros, shall I go and do all the logs again ?

[Pieter De Wit (pieter-insync)]

I see there is another update to edev, tried it, same result :(

[Pieter De Wit (pieter-insync)]

Hi Bryce,

I know you must be busy with the 12.04 release, but can you confirm you saw comment #26

I want to make sure that you guys don't get flooded with requests once 12.04 ships :) or at least confirm that I am smoking my socks with regards to the funky mice :)

Cheers,

Pieter

[Bryce Harrington (bryce)]

Hi Pieter,

Yes, despite not commenting here I've been keeping a regular eye on this bug and others like it. I did see comment #26, and concur that this is an important issue, and also would like to ensure users don't see it post-release. Let me give you an update of where we stand with this.

On IRC, Sarvatt, RAOF, cnd, and myself hashed out about this and other input-related crash bugs we've been seeing recently. We believe we understand the cause. For Precise, we are using xserver 1.11 as a base (to remain compatible with proprietary video drivers), but have backported the XInput stack from xserver 1.12 (needed for multitouch). It is our belief that there was an irregularity in how this backport was done; specifically, the code for parsing the input section of the xorg.conf. See comments #6 and #7 of bug #931397 for details and for the actions we're taking based on these findings.

While we don't think it'll solve every input related xserver crash, we do think it will solve your bug as well as bug 931397. I'd appreciate it if you could continue testing after the fix has been applied, and confirm whether or not it did so.

[Pieter De Wit (pieter-insync)]

Hi Bryce,

Thanks for the update !

I have missed the IRC stuff so I see where the disconnect came in. All
good now and I will carry on testing. You will have a few happy users once
this is solved :)

Cheers,

Pieter
