Lets post here about the install fest preparations. I have not seen too much posting in our forum since the meetup so I thought I would try to start it.
I installed 7.04 on a machine the yesterday which I imagine would be a lot like the type of machine we would encounter at the install fest. The machine was an average system (AMD Athlon, 512MB ram, 120GB HD, Integrated sound, video, network (nvidia)). This system has Windows XP on it which has been in use for about a year. At least 50GB of drive space had been used up. Finally, I did not bother to defrag the disk simply because we would not know if they did or didn't.
I started the Live CD and played around with it some. I even downloaded the proprietary drivers to play with Beryl. It let me do this without installing. Then I started the install. The first few steps are very simple language/locale type. Then the partitioner appeared. I simply left the partition screen with the default options and clicked next. It took only 10 minutes to repartition. Then I went on with the install. It was able to detect my profiles on the old windows drive and I chose to import these into Ubuntu. Very cool.
30 Minutes of installing and the system was done. The only trouble was on the reboot. X did not start. The xorg config file listed the proprietary driver for my video card. I switched it back to NV and started x. Everything was fine. I went and looked at my drivers and noticed the proprietary driver for video wasn't installed. Pre-Downloading that driver for the live CD must have confused the installer. I re-downloaded the driver and rebooted. Beryl and everything came right up.
That was my most recent experience with the latest installer. Fairly easy.
