What's the best way to disable suggesting some drivers?

Any of the following options will work, depending on what you want to achieve:

 - Delete the handler in /usr/share/jockey/handlers
 - Adjust the handler's "available()" method with some custom code if you only want to disable it in particular circumstances
 - Update the fglrx package to drop modaliases (i. e. models) which are known to not work; this could/should even happen in Ubuntu itself

Unfortunately you can't override it in /usr/share/jockey/modaliases (see https://bugs.launchpad.net/jockey/+bug/850223).

Thanks Martin Pitt, that solved my question.

I want to disable fglrx because it doesn't play well with Mutter (and vsynced Clutter in general) and has dreadful issues with dual-screen under Mutter. Since open-source AMD drivers are supported by AMD and work much better, we'd prefer to stick to them by default, but still allow power users to install fglrx if they know what they are doing. So I guess I'll simply delete the Jockey handler.

I'm also leaning towards blacklisting vboxdrv - it also has a lot of known issues and been dubbed "tainted crap" on LKML (see http://www.phoronix.com/scan.php?page=news_item&px=OTk5Mw). In addition, the guest additions version from Ubuntu repos is usually outdated (as of my experience anyway). I hear a redesign of Jockey is upcoming, so you might want to drop it in Ubuntu too.

As for Nvidia, we'll probably investigate installing the proprietary driver on boot to avoid the hit-or-miss reverse-engineered Nouveau. Jolicloud already did that, see https://github.com/jolicloud/jolicloud-hardware

Oh, there's no more handler for vboxdrv. Sorry, my bad.

Thanks a lot for your help!

Hmm, Jockey still suggests installing fglrx even though I've deleted /usr/share/jockey/handlers/fglrx.py
What else shall I tweak to prevent Jockey from suggesting installing it?

Jockey even claims to successfully install the driver despite the fact that /usr/share/jockey/handlers/fglrx.py is missing.

I've found a "disable-jockey-fglrx" package at http://dell.archive.canonical.com/updates/pool/public/d/disable-jockey-fglrx/
Looks like it's exactly what I'm looking for.

For the record, removing the helper didn't help and the above package is complex enough to be useless in our case.

The simplet way to do this for fglrx is to hijack the function available(self) in /data/handlers/fglrx.py and make it always return false.
