I guess ATI should write the list of supported distros for fglrx on the download page... in bold... size 72... with animated GIFs of garden dwarves dancing around...
The release notes state which distros are supported, alternatively
If your distro isn't on the list (or if you start mucking around too much), the message is "You're on your own". Alternatively "Hope for the maintainers to provide assistance".
sh ./ati-driver-installer-YY-MM-x86-x86_64.run --listpkg
fglrx -> select stable distribution releases; for the latest and greatest, feel free to have a look at the FOSS drivers.
Their policy has been hammered down for a while now, what's so hard to understand about it? Also, are stable releases for wussies and lesser beings?
The "but nvidia doesn't do that" argument is as relevant as saying "but in windows I only need to double-click on the icon to launch the installation program". Seriously...
