Ubuntu 7.10 upgrade

This entry is just a place to jot down things ...
My Kubuntu upgrade to Gutsy Gibbon 7.10 went fine and did not notice any change until I looked into Xorg.0.log file. The latest X11 server has the guts of AIGLX inside it but it is turned off by default. The reason being it's dependency on restricted nvidia modules. So I followed these steps:
1) Went into adept and installed restricted-manager-kde
2) Ran restricted-manager-kde
3) Selected NVIDIA accelerated graphics driver
which automatically downloads the nvidia kernel driver and updates xorg.conf
4) Readjust xorg.conf to my liking and restart X server

...and now everything is swell.
