Hibernate and Restriced Drivers (Was: 4 More days...)
Hello developers, There's the decision to ship with a kernel that breaks suspend/resume on any machine using ATI proprietary drivers (and Nvidia I think, but by that point we'd rolled a custom kernel to fix the Ubuntu breakage). This bug, or this group of bugs, will be a source of annoyance to many users. Basically, when you use restricted drivers (both NVidia and ATI), your system will fail to resume from hibernation most of the time. As restricted drivers are enabled by default, this should be considered a regression from feisty. See for example #34043, which I think is still valid for most NVidia users, or #151471 for a more recent incarnation. Sometimes, following the instructions of: https://help.ubuntu.com/community/NvidiaLaptopBinaryDriverSuspend will help make it work, but often it doesn't. What this means is that suspend won't work out of the box in Ubuntu any more. (And if you try anyway it crashes, with the possibility of data loss). (See [1]) I hope this doesn't sound ungrateful. Ubuntu developers are doing a very good job overall, and dealing with binary blobs isn't an easy task. It's alright to know that something is broken right now, but it's worrying to have the impression that no solution is in the offing at all. I'd love to see some sort of Hibernation team created that tries to tackle the problem in a systematic way.
