I had no problem on 2 of my machines.
However, I have an AMD graphics card on one of mine, and the Catalyst Control Center is giving me headaches trying to re-configure my multi-monitor setup.
Thank goodness my new nVidia card is on the way! nVidia has always provided good driver support, so this should be much better.
Edit: I also decided to do the full disk encryption. I like the way it acts-it actually looks good (not necessary, but it sure is nice to have a decent looking password prompt), and it even prevents you from editing the partitions in GParted.
Correct me if I am wrong, but you can not do custom partitioning in the "Something else" option on install and also have full disk encryption. I may not have a swap partition now, but I am perfectly fine with it, and I am planning on upgrading the RAM when prices drop.
I just wish GParted could enter the password so I could add in a swap partition. Oh well, I guess that is the price you pay for security. At least it is open source, so it is likely to get fixed a lot faster if any security flaws are found.
Probably the best thing about it is the boot time. When I say 10.91 seconds, I mean 10.91 seconds. Note that I mean from the time I press enter after entering my password to the time I see the login screen pop up-measuring the time from the BIOS post screen would be difficult to stop and start my watch at the right time.
