Beware AMD Radeon legacy and NVIDIA GeForce legacy users

As it always happens, proprietary video drivers fall short. This time it's because we are, after one year, upgrading X.Org to version 1.13. This means that some legacy drivers have been removed: - AMD Catalyst 12.6_beta_pre897 - NVIDIA legacy 96.xx They don't work with the new X.Org, so either you are on your own or have to switch to open source drivers. Sorry, it's not our fault.
Kernel updates are not forced to users. If you do not intend to update your kernel or you don't even know what a kernel is, you can happily ignore this notice. However, if you are adventurous and want to update your kernel to 3.6 (or later) and you have an AMD graphics card using the proprietary drivers (ati-drivers), you must add "nomodeset" to the boot parameters, or 3D acceleration will stop working. This is because upstream X.Org OpenSource Radeon drivers are not supporting non-KMS configurations anymore. So yes, OpenSource AMD graphics drivers will work 100% out of the box now.
cosa rischio? perdo il 3D? in quale file va inserito nomodeset?
