[Impact]
Apport is disabled in the release itself, so this hook should not be getting triggered at all. However, for some users it does. This wouldn't be a big deal, except it also gets triggered in cases where no GPU lockup was experienced (aka False GPU lockups - bug #983640), which gives poor user experience.
[Development Fix]
Since we want any and all GPU lockup reports in the development release, we leave things as they are, and focus on getting a targeted fix to just #983640.
[Stable Fix]
Since we don't intend for the GPU lockup hook to be run at all, whether or not Apport is enabled, in the stable release we forcefully disable the udev hook entirely.
If someone does specifically want this enabled, they'd need to also manually enable apport and so forth, in addition to re-enabling this udev rule. But I think it'd probably be easier for these people to just manually collect the gpu dump and dmesg directly, so don't expect anyone to need the script.
[Test Case]
The issues have been strange corner case problems that seem to be highly hardware-specific, and not synthetically reproducible.
1. On affected hardware, boot into a regular user session normally
Expected Behavior: No apport popups about GPU lockups
Broken Behavior: Apport pops up dialog about a GPU lockup bug, when nothing of the sort had actually happened.
[Regression Potential]
None really, as this is just disabling functionality we don't need enabled in the release.
The class of regressions to watch for with this would be udev-related problems, or odd apport behaviors. But I don't think anything untoward is remotely likely to happen.
