Comment 30 for bug 939023

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.
