Comment 11 for bug 1465706

I spent a lot of time beating on the proposed Trusty nvidia-346 (346.82-0ubuntu0.2) and nvidia-340 (340.76-0ubuntu0.1) packages yesterday, and things seem solid to me.

Package upgrade/downgrade paths I tested:

331 --> 340
331 --> 346
340 --> 346
346 --> 340

I tested that things work correctly re stopping nvidia-persistenced when removing/purging 340/346, and I gave them my usually "does Unity seem to work?" sanity check and ran the unigine-valley demo. Everything seems good.

I also tested the upgrade from the 346.59 packages currently in the System76 stable Trusty PPA, which although not of direct concern to Ubuntu is something I still needed to check and also attests to the overall correctness of these proposed packages. The upgrade from our 346.59 to the proposed 346.82 works swimmingly.

However, I'm not personally comfortable removing "verification-failed", adding the "verification-done" tag as the one thing I couldn't test is Optimus (as System76 doesn't sell any Optimus hardware).

Note I only tested nvidia-340/nvidia-346, didn't directly test nvidia-340-updates/nvidia-346-updates. But AFAIK, the two flavors are currently identical, so I'd expect the results to be the same.

Also note that I tested with the 3.16 and 3.19 kernels, but did not yet test with the 3.13 kernel.

In summary: from my perspective, these proposed packages are good to go after someone else can test on Optimus hardware and test under the 3.13 kernel (and I'll test with the 3.13 kernel tomorrow if I have a chance).

Thanks!
