[clug] Head up for those thinking of Ubunty Jaunty with older ATI cards

Can't talk to the older cards, but the evil propriety ATI drivers that can be
installed via Jaunty cause xorg to leak memory like a sieve. 1.3Gb RSS was the
worst I've noticed it gobble.
I was getting about 1 - 1.5 days stable between reboots - eventually X would
... not stop, but have to be pushed to repaint the various windows.

Ended up getting sick of that and switched to an older ('06) nvidia card...
which isn't recognised as 3D capable. Sigh.
/me wantz my compiz!

As Robert mentioned, PPA's are pretty cool. Anyone can have one if they so
desire. Quite a few of the Ubuntu Dev's use them to get suckers^W volunteers
to trial beta builds.
eg Luke aka TheMuso with his pulse-audio updates.

I personally, principally use the bzr ppa's:
deb http://ppa.launchpad.net/bzr/ubuntu jaunty main #BZR PPA
deb http://ppa.launchpad.net/bzr-beta-ppa/ubuntu jaunty main #BZR Beta PPA

for example; to get the latest and greatest bzr versions.

ISTR that the kubuntu folks use PPA's to push the latest and greatest KDE apps
as well.
