Not really stated anywhere obvious, but apparently Xgl isn’t the preferred mechanism for all the special effects in Xorg post 7.1, it’s AIGLX that you should be using. It’s integrated too 🙂
So after wasting a lot of time trying to get the nvidia driver working properly with XGL after the latest updates I just searched the docs here, there and everywhere and finally picked up on the ‘just use AIGLX’ vibe.
Maybe I should be reading the release notes… or are they in the release notes at all? I managed to survive gutsy and hardy without changing over to AIGLX and it still worked, so I may just have missed this in the notes somewhere.
If it wasn't for carbon-14, I wouldn't date at all
